Assembly, installation, piping of a boiler room in a private house – prices

An effective boiler room is essential for maintaining a warm and comfortable home. Constructing or remodeling a home necessitates meticulous preparation and thought when installing a boiler room. Every step counts toward keeping your house toasty warm all year long, from choosing the ideal boiler to setting up the plumbing system.

Selecting the ideal boiler type for your house is one of the first stages in building a boiler room. Boilers are available in different sizes and varieties, such as system, combi, and conventional boilers. Every variety has pros and cons of its own, including space needs, hot water demands, and energy efficiency. Through comprehension of your house’s heating requirements and expert advice, you can choose the boiler that best meets your needs.

Installing the boiler is the next step after selecting it. Careful attention to detail is necessary during boiler installation to guarantee safe and effective operation. This entails choosing a suitable location for the boiler, taking ventilation needs into account, and adhering to building codes and regulations. It is strongly advised to hire knowledgeable experts for installation in order to prevent any potential problems and guarantee proper setup.

The plumbing system must be set up to effectively distribute hot water throughout the house after the boiler is installed. In order to reduce heat loss and guarantee uniform heating throughout every room, proper piping layout and insulation are critical. The layout, diameter, and material of the pipes, among other things, all affect how well the heating system works. Collaborating with proficient contractors can assist you in creating and executing a successful plumbing system that is customized to your house’s layout and heating requirements.

Budgeting for the assembly and installation of a boiler room can be complicated by a number of factors. The boiler’s size and type, the installation’s difficulty, and the materials used all affect the final cost. Labor expenses and the cost of any extra parts or accessories should also be considered. Although there may be initial costs associated with purchasing a high-quality boiler and hiring a professional installer, the long-term energy savings and improved comfort of the home can make the investment worthwhile.

In conclusion, there are a number of crucial steps involved in building and installing a boiler room in a private home, ranging from choosing the appropriate boiler to setting up the plumbing system. You can design a dependable and effective heating system that will keep your house warm and cozy for many years to come by carefully evaluating the heating needs of your house, speaking with experts, and setting aside money appropriately.

What you need to know about boiler room ventilation

To keep the combustion process going, a functional boiler needs oxygen, which must be drawn from the surrounding air. Additionally, there is a need to stop carbon monoxide from building up in the boiler room and entering the house. In comparison to the outflow, there should be three times as much fresh air entering the boiler room.

In the boiler room, supply and exhaust ventilation must be installed. Create a channel in the wall across from the boiler to allow for natural ventilation of the boiler room. The channel should have a diameter of 13–15 cm for outputs up to 35–40 kW and 17 cm for higher outputs. It has a ventilation pipe put into it that has a mesh screen and a flap.

Doing the boiler room’s natural ventilation on your own is simple. However, you cannot regulate the amount of air that enters and exits; instead, the weather determines how well ventilation works.

If the boiler room is housed in a different room, louvered grilles installed in the lower portion of the entrance door can be used to supply air from the outside.

If the air draft originates from the street, the standard air inlet size is 8 cm2 of cross-sectional area per 1 kW of boiler output. The entire house’s ventilation system is linked to the boiler room ventilation system. If the air is coming from within, a different standard (30 cm2 per 1 kW) should be used to calculate the opening’s size.

Natural ventilation can be supplemented or replaced with forced ventilation. It is connected to the boiler equipment so that the fans only rotate when the boiler is operating, reducing the amount of electricity used. To prevent explosions and ignition, the ventilation system in gas and diesel boiler rooms should be installed inside the housing.

Automated climate systems are an innovation for people who are curious about the workings of a private home’s boiler room device. Without requiring human input, they automatically maintain the room’s predetermined climate parameters and make adjustments as needed.

An annex housing the boiler room features a steel vertical chimney with a built-in natural draft. The ceramic pipe will last longer. You may want to think about going with a steel-cased ceramic chimney. The durability advantage is still present, but installation is simpler.

Every heating boiler has a combustion chamber, either closed or open. There are no restrictions on the amount of space that can be used for equipment with a closed combustion chamber, and a window is not required. In the first scenario, a vertical chimney allows a natural draft to expel the smoke outdoors. It is vital to maintain continuous ventilation of the room because some of the room’s air also goes there.

In the second scenario, a fan is used to forcefully remove the combustion products from the chamber through a unique coaxial double chimney. One pipe is encased in another pipe within it. The air required to sustain combustion is carried by the outer one, while the inner one carries the smoke.

A typical vertical chimney has a minimum length of five meters. Its end needs to extend past the roof’s upper ridge, and technically, it’s not always feasible to construct a through shaft beneath it.

A chimney in a chimney can be pointed horizontally and is shorter. It is crucial for both kinds of chimneys that their cross-sectional areas are equal to or greater than the cross-sectional areas of the branch pipes they are connected to. Lastly, a few remarks regarding the burner’s design

They are supercharged and atmospheric. Only gas boilers use devices of the first kind. The pressure produced in the gas main or cylinder provides the gas. There’s nothing else to hear, just the sound of the flame burning.

And lastly, a few remarks regarding burner design. They are both supercharged and atmospheric. Only gas boilers use devices of the first kind. The pressure created in the gas main or cylinder provides them with gas. There’s nothing else to hear, just the sound of the flame burning.

In devices of the second kind, air and gas are mixed by a fan to promote more even combustion. Fan noise is something you must endure. Supercharged burner boilers run on both gas and diesel fuel and need a smaller cross-section chimney.

In a coaxial chimney, the combustion products travel through the inner channel, which warms the air from the street as it passes through the pipe. The heated air that enters the furnace lowers fuel consumption and boosts equipment efficiency.

General regulations for the arrangement of boiler rooms

When planning a boiler room project of any kind, the following considerations must be made:

• there must not be more than two boilers in the room;
• the walls and floor must be made of non-combustible materials, for the walls will be suitable brick or concrete, for the floor – non-slip tiles, steel sheet or concrete;
• the door for the boiler room must be fireproof and open only to the outside;
• If the boiler is located in a separate annex, there should be two doors: one leading into the house, the other – to the street;
• the room must necessarily have a window with a vent;
• there must not be any combustible materials in the boiler room;
• any part of the heating system must always be freely accessible.

The best course of action, if the house is newly constructed, would be to incorporate a boiler room room, constructed in compliance with SNiP standards, into the design. It is simpler to install the boiler in an annex or other standalone structure if the house is already constructed.

Installing a mini-boiler room, a unique container housing all of the heating equipment, is the answer if there is limited available space. Such boiler rooms are small enough to be placed anywhere.

A mobile boiler room, which is a distinct room constructed from sandwich panels and finished with non-combustible materials, is an additional method of conserving space.

Electric boiler for a private boiler room

The electric boiler is the safest type of boiler to use in a private home. It does not require the equipment of a separate boiler room. The coolant doesn’t require ventilation because it produces no combustion products when it heats up.

These boilers are easy to install, quiet when operating, and require little maintenance. Electric boiler efficiency can be as high as 99% in certain situations. The drawbacks include the network’s high power requirements and reliance on steady operation.

As long as it is convenient, the electric boiler can be positioned in any corner of the house. It is mostly used as an extra source of heat and uses a lot of electricity.

The electric boiler is connected using various schemes: radiators are connected to it, and a cascade installation option is provided in case you need to heat a large area. There are two schemes used for the piping: straight and mixing. A burner controls the temperature in the first scenario, whereas a mixer with a servo drive controls the temperature in the second.

Basic requirements to the room for the installation of gas boilers

Every gas boiler has a different design, which includes a different kind of combustion chamber. When it’s closed (a coaxial chimney is installed), the room’s measurements are irrelevant. Additionally, there are some standards (at the very least) for models with open chambers:

• 7.5 m3 – for appliances up to 30 kW;
• 13.5 m3 – up to 60 kW;
• 15 m3 – for boilers with output over 60 kW. In this case, for each additional "kilowatt" of the device must be added 0.2 m3 of space.

As we all know, volume is the result of multiplying length by width by height. Thus, the final parameter is fixed and cannot be smaller than 2 m. As a result, it is essential to determine the room’s size by "looking back" only at its height.

Location of the furnace room

On any level, including the ground and basement. This holds true for all models in which a pump forces liquid (such as water or antifreeze) through pipes. However, only in the cellar or basement if the boiler series TLO (natural circulation of the coolant) is in place.

Illumination

There must be at least 0.03 m2 of glazed surface in each "cube" of space. Additionally, a minimum of one 0.25 m2 window facing the street (devices with closed chambers are exempt from this requirement).

Boiler installation place

• From the front panel of the boiler to the wall (door) – at least 1 m.
• There should be free access to the device from all sides. This is necessary for the convenience of carrying out maintenance work in its entirety.
• Boilers are placed on a pedestal, the height of which, as well as fire requirements for its arrangement are stipulated in the Instructions for installation of the device.
• The wall (or walls) at which the boiler is located must be of non-combustible materials (or securely protected against thermal effects).

Remember that everything mentioned above only applies to individual homes with centralized gas supplies. When using liquefied gas (cylinders), there are certain quirks. For instance, in this instance, installing the boiler in a basement room is not permitted. Consequently, more details about these subtleties ought to be provided.

Ventilation

• The room is connected to a common ventilation system, the connection is located on the ceiling of the boiler room.
• The boiler room chimney consists of 2 ducts, with a spacing of at least 25 cm. One of which is used directly for the installation of the chimney, and the other for its cleaning.
• As a rule, fresh air is supplied through a ventilation grille installed at the entrance door to the boiler room.
• There are standards for the size of ventilation inlets: for external air intake – 0.08 m2 x 1 kW of boiler output, for internal air intake – 0.3 m2 x 1 kW.

Requirements for the premises of the boiler room in a private house

The specifications for the technology of equipment installation in a private boiler room and the room itself are spelled out in detail in SNiP. The principal ones are:

• The walls of the room can be made of concrete or building bricks. It is allowed to apply ceramic tiles or fireproof plaster coating. These requirements are dictated by fire safety considerations
• When installing a floor boiler, the floor is covered with a concrete screed (in the future, tiling is possible) or sheet metal coating. A podium must be made under the boiler
• The wall-mounted boiler is mounted on the wall with the preliminary installation of a metal sheet on it. There is another option, in which this wall must be covered with tiles
• Flammable and explosive substances are not allowed in the boiler room. Only fuel stored in a special way can be excluded
• There must be sufficient space around the boiler for unobstructed access to it during operation. In addition, it is necessary to provide space for maintenance or possible repairs. That is why, before starting work on the installation of equipment in the boiler room with a small area, we strongly recommend making a plan of its arrangement
• For the boiler room in a private house when installing gas boilers there is a strict regulation on the overall dimensions and arrangement

Room Size: 0.03 m2 / 1 m3

Being there. Required opening to the exterior

• To the premises in which the solid fuel boiler is installed, there are also some requirements. The distance between such a boiler and the nearest wall must be at least 10 cm. There is also a condition on the required minimum window area in such rooms. Namely, for each kilowatt of the calculated thermal output of the boiler must be provided – more than 8 square kilowatts. cm. glazing. The chimney should have the same size of the transverse diameter along its entire length and, if possible, contain as few turns as possible. If it is supposed to install a boiler that uses coal or wood as fuel, the area of the room in which it is installed should be – more than 8 m2
• Electrical wiring in the premises under consideration should comply with the PUE norms. If an electric boiler is to be used, its conductive terminals must be earthed
• The arrangement of the boiler room, which operates on diesel fuel, assumes in the immediate vicinity of the structure to place a large (volume of 1.5 m3 or more) metal thick-walled fuel tank in the ground. In the boiler room itself, a tank is installed, into which the fuel enters from the underground tank. It is necessary to ensure unobstructed access to this tank

In addition to the previously mentioned, a great deal of subtleties and bottlenecks need to be considered when installing the boiler room in order to produce a high-quality end product.

Working with "ViDstroy Engineering" gives you ownership of a boiler room that satisfies all SNiP requirements and is safe, dependable, and technically sound!

Boiler room size in a private house depending on the boiler

• At capacity up to 30 kW the volume of the room is 7,5 meters.cube. In this case, the boiler room can be built into the house or combined with the kitchen.
• 30 – 60 kW – respectively 13.5 m.cube (in this case the boiler room can be represented by an annex or a separately allocated room on any floor of the house);
• 60 – 200 kW – at least 15 m.cube (a separate building, annex or the first, basement or cellar floor of a house).

Having a minimum 0.55 m window is required.The boiler room needs to have a condensate collection drain, 0.8 m wide doors, and a separate room.

Dimensions for gas boiler room

There needs to be a chimney in the gas boiler room, one that is level with the roof and has a cleaning channel.

There needs to be an emergency gas shut-off system installed in the gas boiler room. If liquefied gas is utilized instead of regular gas, the boiler room’s location in a cellar or basement is not allowed. Either way, the ceiling height needs to be 2.5 meters or more.

Dimensions for an oil boiler room

Waste oil, fuel oil, or diesel fuel can be used in liquid fuel boilers.

The same measurements that apply to gas boilers also apply to the boiler room size required for private homes. There is a fuel tank and an area of 4 sq. m. per boiler when calculating area. It is also possible to install the fuel tank outside of the boiler room.

As diesel boiler rooms are noisy, it’s best to set aside a different space for them. The space needs to be properly ventilated for both gas and liquid fuel boilers. For the boiler room’s bottom air inlet, one of the walls needs to have a louvered window. For every cubic meter of space, there should be a window measuring 0.03 m square meters (but not less than 0.5 m). In this instance, a vent ought to be in the window. door width of at least 0.8 meters.

Because they must adhere to the strictest fire safety regulations, liquid-fuel boilers are rarely used.

A built-in or annexe boiler room lacks the safety, noise, and living space savings that a freestanding boiler room offers.

Dimensions for a solid fuel boiler room

The most cost-effective boilers use solid fuel since it is the least expensive and doesn’t explode, making the regulations less stringent.

With an efficiency of no more than 75%, the solid fuel boiler’s low efficiency is perhaps its greatest deterrent. Fire extinguishing equipment is a need for boiler rooms with solid fuel boilers. Boiler room dimensions must be at least 8 meters square. The interior finish of the solid fuel boiler room should be composed of non-combustible materials, and the room itself should be freestanding. The boiler room, where the coal-burning boiler is located, needs to have concealed wiring. Given that coal dust can be explosive, the best option is in steel pipes.

Dimensions for an electric boiler room

Installing an electric boiler room in a wooden house is the only appropriate solution because, according to all safety rules and regulations, they are the most fire-safe. The quality of the wiring in electric boiler rooms is crucial, as they save space and don’t require any additional ventilation. They do, however, need a safety circuit breaker. The priciest method of heating a home is with an electric boiler.

It is not required to have a separate room for the boiler room; the boiler can be installed anywhere that is convenient.

When designing a private home, the type of boiler to use, its location, and its capacity should all be considered, keeping in mind the heated area, needs, and capabilities of the building. A sensible solution to the issue of providing heat for a private residence is individual heating, which complies with safety regulations and standards and lets you adjust the temperature to suit your needs.

What to be guided by

A unique document dated July 1, 2003, specifies the requirements for private boiler rooms (we are talking about SNiP 42-01-2002). This paper ought to act as a blueprint for setting up the furnace room. Understanding the standards has some benefits, even though project development is typically carried out by experts. This allows the likelihood of using various equipment types and the approximate amount of installation work to be determined in advance.

As a result, the dwelling meant for the boiler room can be modified to meet SNiP requirements even at the construction stage. It is advisable to work with the design department of the gas supply company to resolve any issues or contentious issues. Every unique building has unique quirks that can only be resolved in relation to the floor plan.

Finishing the boiler room from the inside

The boiler room’s brick and concrete walls are painted with water-emulsion paint and plastered. Metal facing panels and ceramic tiles are examples of additional decorative finishing. Leaving the wall surface in its original state is not recommended. The boiler equipment is negatively impacted by the dust and its presence.

A fireproof compound is applied to the walls of a wooden house. It is advised to plaster them and cover them with non-flammable plasterboard sheets from above. Additionally, aluminum sheets should be attached to the wall surface behind the boiler to provide insurance.

Another defense against smoke, fire, and other elements is plastering. By applying a specific type of heat-resistant plaster, you can raise the fire resistance. It can endure heating at high temperatures for up to 30 minutes, as well as an open flame. for a maximum of 2.5 hours.

A cement-sand screed is used to level the floor. Ordinary ceramic tiles are not strong enough to cover the entire floor because there is a chance of dropping a heavy object due to the weight of the boiler equipment. Porcelain stoneware will be more dependable. Because of their extreme strength and resistance to fire and high temperatures, these tiles are highly durable.

The drainage gutter will be shielded from unintentional leaks. If this isn’t feasible, the boiler should be elevated on a pedestal to prevent potential water contact and waterproofing should be installed around the perimeter at a height of 5 to 10 cm from the floor. It is simple to construct out of bricks and covered in porcelain tile meant for flooring.

The boiler room’s floor and walls are tiled, which will help to maintain the space clean.

Its installation is identical to that of similar operations in other rooms, but before beginning any work, make sure that all points of entry for communications are marked accurately.

It is preferable to select light-colored ceramic granite with a matte texture for the floor.

There are faint shoe prints and dust on it.

It is preferable to select a light-colored ceramic granite with a matte texture for the flooring. Dust and shoe traces are less noticeable.

Pipes and wires are located in the boiler room under the ceiling. Construct a box out of the same drywall that was used for the walls to conceal them. The outside of the box is painted and plastered. It makes sense to keep the revision windows in there and use detachable metal grids to close them.

Installing wooden or plastic windows in the boiler room makes no difference. Both will burn in a fire. Additionally, plastic will start to melt and release harmful compounds.

2. The main elements of the boiler room in a private house

It is advantageous if the house is small and one small, two-circuit gas boiler can handle all of the hot water and heating needs. However, this won’t usually be sufficient; instead, you’ll need a complete set of tools, which could include a number of the following components:

• boiler – the heart of the whole boiler room. It will be responsible for heating water for the heating system. Heat can be obtained by burning different types of fuel: liquid, gaseous or solid fuel. A separate case – electric boilers. In some cases it is installed two boilers at once, to ensure that the private house is completely energy independent;
• boiler. If a single-circuit boiler is used, then a boiler will have to be used to heat water for the hot water system;
• expansion tank. Water from the heating system will flow into this tank, if the pressure in it rises. In this way, pipes and radiators are protected from bursting;
• heat accumulator. Installed not always, despite the fact that it is a very useful element. In this tank accumulates superheated coolant, "excess heat", which is then fed into the heating system. In this way, resources are saved and safety is improved. Especially relevant is the presence of this element for solid fuel boilers and if there are two boilers of different types;
• distribution manifold. Necessary for proper distribution of the coolant throughout the system, regulates the temperature;
• circulation pump. Necessary only in systems where the coolant is forcibly circulated;
• chimney. Necessary for the removal of combustion products outside the house. The chimney is not necessary only for an electric boiler;
• safety and control group – a set of devices that monitor the temperature and pressure in the boiler and system. It can also include sensors that monitor the condition of the air in the boiler room;
• automatics receives commands from the user regarding the required temperature, collects the data of the safety group and allows the correct regulation of the main parameters of the system;
• shut-off valves Necessary to control the flow of coolant;
• pipes, through which the water from the boiler flows to the radiators;
• filter required for water purification before it enters the boiler and boiler system. If the water in the region is saturated with salts and contains mechanical impurities, you can not do without a filter – otherwise the equipment may soon fail.

Utilizing each of these components is not required; their selection is based on a variety of criteria. The house’s location and fuel type come first.

Requirements for a furnace room in a separate room

The following extra requirements must be met in addition to the basic requirements if you wish to equip the boiler room separately in the basement or annex:

• fire resistance of the walls separating the rooms;
• natural light;
• ventilation system with the frequency of air replacement 3 times/hour;
• separate exit to the outside;
• Ensuring easy access for boiler maintenance;
• the volume of the room is not less than 15 cubic meters.

If you install the equipment in a separate standing boiler room, you must also adhere to the fundamental SNiP norms:

1. The foundation of the separate building must not be in contact with the foundation of the dwelling house.
2. The walls and roof must be finished only with fire-resistant materials.
3. When erecting the building, mortar with sand must be used.
4. For the boiler you need to build a separate foundation 15-20 cm from the floor.
5. A drainage system must be installed so that the coolant can be drained out of the system if necessary.

The fact that the gas heater won’t be audible while it operates is a nice bonus of this setup.

Building regulations

Any fuel can catch fire. Gas is likewise exploding. How to choose a boiler for heating a private home explains that floor standing boilers are large and not very compact. The open furnaces found in half of the heating equipment models inevitably allow gas, smoke, and carbon monoxide to seep into the surrounding area in the event of a leak.

As such, installing the boiler requires a separate room. Here, you can arrange the system’s components in the best possible way to allow for easy access to them and to prevent unintentional mechanical impact.

The aforementioned qualities are not present in electric boilers, and a boiler room is not required. However, for aesthetic purposes, the electric boiler can also be positioned in a different space (what are electric water heating boilers).

Boiler room configuration variations in private homes:

• in the basement, on the ground floor;
• in the uninhabited room of the cottage;
• in the attic or on a flat roof;
• in an annex;
• in a freestanding technical structure (in a barn, utility block, garage, etc.), the size of the boiler room in a private house is determined as 15 cubic meters plus 2 for each kilowatt (instruction MDS 41-2).);
• in its own mobile unit.

Let’s look at the essential specifications for a gas boiler room in a private residence (they are a little bit more than for units on other fuels). Boiler capacity determines boiler room dimensions in private homes (general requirements for the room for installing a gas boiler in a private house).

The boiler room in a private residence must have a minimum area of 15 cubic meters if it is over 60 kW, 13.5 if it is within 60 kW, and up to 30 kW if it is wall-mounted.

In the final scenario, if the following conditions are satisfied, the boiler may be installed in the kitchen:

• The wall for installation – capital, made of fireproof materials. Wooden wall must be plastered beforehand. Another option for tiling is tiling in the boiler room in a private house;
• The ceiling must not be lower than 2.5 meters;
• It is obligatory to install an additional ventilation system. Above the floor, an opening for supply ventilation is equipped and is taken away by a grille. For ventilation there must be a vent or transom;
• good natural light. The area of the window in the boiler room of a private house – at the rate of 30 square meters. centimeters of glazing per cubic meter of room;
• door width – from 0.8 meters.

Requirements for a separate furnace room in a private residence—possibly a little bit more. There must be a minimum 45-minute fire resistance on the walls dividing it from the living rooms. At least three air exchanges should occur each hour. A private home’s boiler room door must open outward, toward the street.

A second door that leads inside the house might exist; it needs to be fireproof. According to instruction MDS 41-2.2000, a private home’s boiler room capacity greater than 60 is equal to 15 cubic meters plus 0.2 per kilowatt. Basements are not permitted to have LPG boilers installed.

A few more requirements are provided by SNiP (2008 edition) in the event that the boiler room is situated in a detached mini-block or the garage of a private residence. The building needs to be situated apart from the main one and not next to it.

Depending on its weight, the boiler may need its own foundation underneath, or it may just need a concrete pad that is no more than 20 centimeters above the floor. The roof and walls are made of materials that resist fire. For the walls, the foundation, etc., use concrete mortar. – including sand in the mixture.

Separate sewer branch for coolant draining. If the boiler room is located in an annex, it must be next to the house’s blank wall, at least one meter away from the doors and window openings.

Free access to the operational components is required by design guidelines for a boiler room in a private residence in case of maintenance or repairs.

A minimum of 70 centimeters should separate the boiler from the wall, and a minimum of one meter should separate the front panel from the wall. The passageway for models with side or rear service should be 1.5 meters.

The boiler is installed at least 10 centimeters from the wall if the service lumen is not needed. Place a non-combustible screen (roofing steel, asbestos 3 mm) on the wall. Installing a screen between the wall and the wall-mounted model is required. Dimensions: 70 cm at top, 10 cm on three sides as a reserve.

Gas boiler room pros

As of right now, the primary heating systems for homes, businesses, construction sites, and greenhouses are gas boilers, both domestic and foreign. In addition to the previously listed benefits, this type of system’s affordability and simplicity of use were also major factors in its broad application.

• Gas boiler room

A heat exchanger, which enables the conversion of one form of energy into another in the boiler room, is the fundamental component of any manufacturer’s gas heating system. When using a gas boiler, the chemical energy of the gas is transformed into thermal energy of the water, which serves as the room’s primary source of heating.

Boilers are classified into two categories: wall-mounted and floor-standing models. The boiler must actually be raised to a level above the floor because it is sometimes not feasible to place it on the floor due to building layouts. Wall-mounted boilers are smaller and somewhat lighter than floor-standing boilers, but it’s not always convenient.

Furthermore, gas boilers are classified based on the energy intensity principle. Boilers are classified as single- and double-circuit boilers based on this feature. Heat is transferred directly to a single tank (cavity) in water by means of the combustion chamber’s walls in a single-circuit boiler. After that, the water enters the heating mains via the extraction system. As a result, a single-circuit boiler is limited to space heating and can only produce one line of heat carrier.

There are multiple water jackets surrounding the combustion chamber of a two-circuit boiler. Convective heat exchange between the second circuit’s water and wall provides heat to it because the burner, the energy source, heats the adjacent circuit. Consequently, two heating mains can receive full heat supply from gas two-circuit boilers simultaneously. Additionally, one line may serve as a dedicated heat source, while the second line may serve as a steady supply of warm water.

Boiler room ventilation system

In order for the heater to function as efficiently as possible (and the principle of its operation, once again we remind you, is based on the combustion of gas and the subsequent release of heat), it is necessary that the room is constantly supplied with fresh air, which is essential for the removal of fuel combustion products. In most cases, normal natural ventilation is sufficient for the air exchange in the boiler room to reach the required level. Weathered doors and window frames, as well as a number of other places where there are gaps for one reason or another, provide quite a sufficient volume of fresh air. But if all this is not enough, because the room is sealed, it is desirable to look at the possibility of equipping an additional ventilation system. And if this is not done, the products of combustion will remain inside the room, leaving behind traces in the form of soot and soot on all surfaces. Moreover, the unattractive appearance of the furnace room is only the least of the problems that will befall you in the absence of proper ventilation.

Natural ventilation

If the power of the heater will not exceed 30 kilowatts, then for the installation of natural ventilation, it is necessary to simply drill holes in the walls 10-15 centimeters and install in it a plastic pipe of the appropriate size – so we will make a kind of channel-air duct. The only thing left to do is to protect this channel from insects and debris entering it. For this purpose, we can use an ordinary mesh made of iron or plastic. In addition, the inner part of the channel should be provided with a back draft valve, which is necessary for the air to leave the room. The ventilation hood should be equipped in the same way, and it should be protected from atmospheric precipitation at the outlet.

However, where would be the ideal location for the air inlet? What can we learn about this from the specifications for a boiler room in a private residence? They state that such an opening needs to be situated from the bottom, close to the fuel box. In this instance, fresh air enters the combustion chamber directly and does not circulate throughout the furnace room. It is preferable to equip the hood directly above the appliance because, as you are aware, combustion products rise upward.

Artificial ventilation

It is not always feasible to install natural ventilation. After all, you have no control over its operation and it primarily depends on the weather. Then, it is preferable to use the other option, which is artificial character ventilation.

It’s crucial! The primary components of this design are the fans; the choice of fans should be made in accordance with the boiler’s maximum air flow rate, plus an additional thirty percent. In reality, we have everything on ventilation.

In actuality, ventilation covers it all.

In this article, we delve into the assembly, installation, and piping of a boiler room in a private house, focusing on the associated costs.

Installation of the ceiling with your own hands in a private house

Installing the home’s ceiling.

For the upper floor, the primary need is that it be lightweight. This is to guarantee safety because the upper portion of the building will sustain the most damage in the event of an explosion. Because of this, the energy can only be destroyed by demolishing the upper ceiling and not the walls.

Furthermore, adherence to insulation standards is required. Heat-reflective film or KVL or GKL sheets covering the ceiling can be used for this purpose. The boiler room needs to be 0.75 hours fire resistant in order to stop fire from spreading throughout the building. The boiler room’s fire-resistant components must be treated with a specific composition and the right building materials must be used.

4. Boiler room in a private house safety requirements

It needs no explanation that the boiler room is a place of increased danger. That is another question. How should the space be set up to provide optimal safety, comfort, and equipment accessibility?

Standard specifications for a private home’s boiler room:

• The walls should be made of concrete or building bricks. It is allowed to use ceramic tiles or plaster – these are non-combustible materials;
• when installing the boiler on the floor, a concrete screed is required; the floor can also be covered with a sheet of metal;
• when installing a wall-mounted boiler, the wall area must be tiled or covered with a sheet of metal;
• explosive and flammable substances must not be stored in the boiler room. This does not apply only to the fuel, which will be stored in a special way;
• sufficient space must be left around the boiler so that it can be easily accessed for operation, maintenance and repair. If the boiler room is allocated a small room, it will be difficult to place all the equipment – it is better to draw up in advance the layout of the boiler and other elements;
• the door leading from the boiler room to the house must be fireproof.

Making a project for the equipment placement and considering all the requirements set forth by regulations such as SNiP on boiler plants II-35-67, Code of Regulations for the design of autonomous heat supply systems SP-41-104-2000, and Instruction on the placement of heat generators MDS 41-2.2000 is preferable, ideally, even before the boiler room is constructed.

Boiler rooms with a gas boiler

If a gas boiler is installed and operated improperly, it can result in a fire or even explode.

The following elements need to be considered when installing a gas boiler:

• the room where all the equipment will be located must be at least 6 m2;
• the height of the room is not less than 2.5 m;
• volume of the room – 15 m3 or more;
• boiler room walls adjacent to living quarters must have fire resistance of not less than 0.75 hours;
• the minimum size of the window opening is 0.03 m2/1 m3 of the room;
• availability of a podium under the floor boiler with a height of at least 5 cm;
• 1 m2 of free space must be left in front of the boiler; between the equipment, walls and other objects there must be a passage at least 70 cm wide, otherwise access to the boiler will be difficult;
• mandatory ventilation and sewerage;
• width of the doorway is not less than 80 cm, the door opens outwards;
• for boilers with a capacity of more than 350 kW it is necessary to build a separate building;
• if the boiler room is located in an annex, it must be near a blank wall. Minimum distance to the nearest window – 1 m.

This is in addition to the need to fulfill all prerequisites.

Boiler rooms with fuel oil boilers

In this instance, it is necessary to consider the following requirements:

• the distance from the boiler to the nearest walls and objects – from 10 cm;
• 8 cm2 of window opening must be provided for every 1 kW of output;
• the chimney should have the same diameter along its entire length and as few turns as possible;
• the inner surface of the chimney can be plastered, but it is not necessary;
• the chimney must have a special opening for its maintenance;
• for boilers that will work on coal or wood, the area of the boiler room must be at least 8 m2;
• when using a coal-fired boiler, it is necessary to make a concealed type of wiring, as coal dust is characterized by high explosion hazard;
• the space in front of the boiler must be free, so that it is possible to add fuel and clean the ash pan;
• walls made of insufficiently fire-resistant materials should be lined with 2.5 mm thick steel sheet.

Boiler room with diesel boiler

The following is a list of requirements:

• in the boiler room, or better outside it, it is necessary to place a metal thick-walled tank with a volume of at least 1,5 m3. From it the fuel will flow into the boiler tank. Free access to the tank must be provided;
• from the boiler burner to the opposite wall must be at least 1 m of space.

Boiler room with electric boiler

An electric boiler has no noise, no smell, and doesn’t burn fuel. There is no need to set aside a specific space, and ventilation needs are not unique under. All that needs to be kept in mind is that the boiler’s conductive terminals need to be grounded.

Types of boiler rooms in a private house and norms according to SNiP

A private residence is heated by boilers:

• gas;
• solid fuel;
• electric.

SNiP II-35-76 contains the requirements for each type’s installation and operation.

Gas boiler

According to SNiP, the space in which this equipment is intended to be installed needs to meet the following requirements:

• area – not less than 6 sq. м;
• ceiling height – more than 2.5 m;
• room volume of at least 15 cubic meters. м;
• window glazing area – 0,3 and more sq. m. m per cubic meter of room.

It is not necessary for gas equipment that has a capacity of 30 kW or less to have its own room.

In the event that the boiler room falls short of the necessary measurements, an exhaust duct larger than 150 mm can make up for it.

A door may have a minimum width of 0.8 meters.

The interior finish of the room needs to have a fire resistance coefficient higher than 0.75 hours. In this case, tile and plaster work well.

Installing methane gas boilers in the basement or attic is permitted. The equipment cannot be installed above the first floor if it runs on liquefied gas.

The following conditions must be met by SNiP if the gas boiler room is to be housed in a different structure:

• the foundation of the boiler room must not be connected to the foundation of the house;
• the roof, walls and floor must be made and lined with fireproof material, as gas-fired equipment gets very hot;
• the device must be installed on an additional foundation, at least 20 cm high;
• another foundation is needed for the chimney pipe.

Since gas equipment produces a lot of noise when it operates, having it in a different building will greatly lessen the noise pollution.

Water from the heating system must be discharged into a sewerage pipe located in the boiler room, along with a water supply system.

If both boilers have the same heat exchanger resistance, an alternative fuel boiler can be added to a room that has gas equipment.

Solid fuel boiler

Since solid fuel boilers do not explode like gas-fired boilers do, there are laxer regulations regarding how a boiler room should be set up.

The specifications for the gas boiler room and the solid fuel boiler room should be the same:

• floor area – from 6 sq. m. м;
• height – at least 2, 5 m;
• volume of the room – more than 15 cubic meters. м.

There must be a steel sheet in front of the boiler and non-combustible materials for the walls and floor. The wall has to have an asbestos screen on it.

The device itself should ideally be installed on a second foundation that is 8 to 10 cm high.

In the boiler room, at least one window is required. Its measurements are based on the boiler output and are computed using the following formula: 0.88 square meters per kW.

The spigot’s diameter and the chimney’s size need to match. Since smoke stains chimneys, there needs to be a cleaning access point on the chimney itself. If this isn’t done, the fire will eventually go out and the draught will get weaker. The boiler will thus produce less heat as a result. Either the chimney needs to be sanded, or an asbestos-cement pipe needs to be put inside of it.

Diagram showing the proper chimney height ratio

The chimney needs to be at least five meters tall. There should be three or more pipes if you require any that have bends or turns in them.

The formula is used to determine the hood’s size. Per 8 square centimeters of hood, the device uses 1 kW of power. hood circumference in cm. The 8 square centimeters would become 24 square centimeters if the equipment was found in the basement.

The location of the device itself should make it simple to access any part for maintenance or routine inspections.

Solid fuel equipment is not completely safe, so the space needs to have a fire safety system. A fire extinguisher, sand, etc., are essential.

Electric boiler

In SNiP, there are no explicit limitations for this kind of boiler. Although installing it in a different room is not necessary, fencing it in is advised. A water supply system cannot be located close to the electric boiler. Since there are no combustion products produced when an electric boiler operates, a ventilation system is not required.

The electric boiler is thought to be the safest and most user-friendly because of its complete automation of the heating process.

Every client request is considered throughout the boiler room’s design and installation process. Should these desires deviate from SNiP, we will modify them and accommodate them within the appropriate boundaries.

Types of boilers

Separate single- and two-circuit boilers based on their operating principles. In the first scenario, the boiler only supplies power to one circuit—the heating circuit—and heats water for household use. One way to think of this design is like a storage water heater. In the second scenario, the boiler’s built-in heat exchanger supplies hot water to the hot water supply system, which functions similarly to flow-type water heaters.

You can store and use hot water in a reserve regardless of the heating operation when you have a system with a single-circuit boiler and boiler. With two-circuit boilers, the house’s hot water supply comes first, and heating is turned off while the hot water is being used. Two-circuit boilers are typically found in summer homes that are not occupied during the colder months, or in smaller homes with low hot water consumption (up to 150 m³ with one or two bathrooms).

Boilers can be classified as wall mounted or floor standing depending on the type of construction.

1. Floor standing boiler is installed on a podium in a room specially designed for boiler room (boiler room). It is possible to erect a freestanding building. The boiler can be steel or cast iron. The latter is more durable, its service life can reach 50 years. The boiler room itself is subject to strict SNiP requirements, if it is not complied with, the boiler room cannot be commissioned.
2. Wall-mounted boiler is made of steel and can be installed in any room of the cottage except for the bathroom. This is a modern compact device, which already includes a hydraulic pump, expansion tank, and the necessary set of automatics that can ensure comfortable operation of the heating system. Wall-mounted boilers have only two disadvantages: relatively short service life (compared to floor standing boilers) and low power (12 – 25KW). They are installed in houses up to 150m2 and apartments with autonomous heating. Today you can find boilers of higher capacity – up to 40KW, which can heat areas up to 400m2, but they are very expensive.

Boiler room diagrams

The scheme of heating (diesel (Fig. 3), gas, etc.) is made up of pipes, a boiler, and other crucial communications components that allow the system to operate efficiently.

The heating boiler seems to be a heat source. The fuel burns in the chamber, heating the unit’s heat carrier. Heat is brought into the space by radiators and pipes.

Residents get hot water from a boiler, also known as a water heating tank. The water is heated by a tube inserted into the center of the tank. The collector conducts and distributes the heating system coolant circulation in a convenient manner.

The purpose of the expansion tank is to remove water, which expands in volume when heated. A safety group with a deflator, pressure gauge, and extra valve prevents emergencies.

There are specific requirements for every gas boiler in your home because they pose a greater risk of explosion. The gas heating systems’ electrical equipment is removed from the space. The concealed electrical wiring is housed in steel pipes, and the luminaire needs to be hermetic. It is important to read the instructions carefully before purchasing a gas boiler as they provide information on how to connect the appliance. The installation of the gas unit must follow the specifications found in the technical documentation. It will be challenging to comprehend on your own, so it is wise to speak with an expert who knows the gas boiler’s connection scheme better than anyone else.

Gas boiler room, schematic (Fig. 5)

The requirements are significantly less stringent for boilers that run on liquid and solid fuel instead of gas. Electrical wire needs to be concealed, and lighting equipment can be shielded with metal mesh. The boiler room is equipped with the following scheme of work: sewage and water pipes are connected to it, and the communications need to be insulated.

Design of gas installations

Complex equipment cannot be installed without specific documentation governing its location at the site and ongoing operation. Thus, it is essential to complete the design of a gas boiler room before making the purchase and installing it. SNiP II-35-76 states that it must consider the room’s technological features. The following steps are involved in the actual process of developing a gas boiler room project:

1. Information gathering (the area of the room shall be specified);
2. Specifying the purpose and capacity of the boiler room;
3. Carrying out a thermal calculation;
4. Selection of equipment;
5. Execution of drawings and notes to them;
6. Project approval.

Not only must the installation’s purpose and capacity be determined, but the calculation that is part of the gas boiler room’s design must also be completed for the equipment to meet the requirements. This will facilitate the proper unit selection and ensure that the equipment operates efficiently. It is necessary to consider the following parameters when performing this calculation:

• Gas pressure in the system;
• Lighting;
• Ventilation;
• Design features of the equipment;
• The window area of a gas boiler room;
• Placement.

The gas pipeline must be able to sustain a pressure of 3 kg/m² for residential and public boiler rooms and 6 kg/m² for production boiler rooms, per normative requirements. There is also control over lighting. A gas boiler room’s total lighting and glazing area cannot be less than thirty percent of the building’s largest wall. Lighting in the boiler room is provided by fire-safe sources at night.

Because the gas is toxic to humans, it is necessary to set up a three-way air exchange in the areas where the equipment that uses it is located. A valve composed of asbestos board with an area of at least 0.15 m² must be installed on boilers.

View this video to learn the prerequisites before installing a boiler:

Equipment placement is done while closely adhering to safety regulations and maintaining the space between building structures and heating units. The gas boiler needs to be insulated with fireproof walls if the boiler room is situated in a nearby room.

The equipment’s power is chosen based on the dimensions of the space. A unit up to 30 kW is appropriate for a 7.5 m³ building. Only boiler rooms with a minimum volume of 15 m³ are suitable for the installation of more potent units.

Mounting and installation of the boiler room

An installation like this consists of multiple components that function as a single complex. For this reason, only experts with the necessary credentials should install a turnkey gas boiler room. It is also impossible to characterize the procedure as simple. The following actions must be taken while performing installation work:

• Analyze the area of the room;
• Evaluate the capacity of ventilation;

Examine additional factors that need to be considered in order to ensure the boiler room operates safely.

Furthermore, installations that run on any other fuel type in addition to gas are subject to these regulations. Given that each of them is a sophisticated piece of equipment, careful consideration must go into both selection and installation.

Watch the video to see the relationships and subtleties at work:

Only experts should be assigned such tasks. After all, it is extremely difficult to comprehend the peculiarities of the equipment’s functioning without the requisite knowledge and experience. Furthermore, even the smallest mistakes and computation errors during the installation process may result in future emergencies in addition to depriving you of operating permission. And there could be dire repercussions from this.

Gas boilers should be installed at the locations close to the central mains, according to experts. In this instance, installing tanks to store fuel reserves won’t be necessary because this gas is thought to be among the most profitable. According to experts, the lifespan of gas-fired boilers is significantly longer than that of their oil-fired equivalents. However, because a gas leak could result in an explosion, installing such equipment is only feasible with strict adherence to all technological standards. Gas boiler rooms are typically outfitted with leak detection sensors or specialized pressure control systems to guard against this.

Businesses that offer boiler equipment installation services include all required technological processes in their prices, from unit selection and transportation to configuration and testing.

Service	Price (USD)
Boiler Installation	$2000 – $5000
Piping Installation	$1000 – $3000

A boiler room installation is a major investment that can significantly increase your comfort and energy efficiency in your private home. Even though the initial expenses could seem high, you might end up saving money on energy bills over time.

It’s crucial to account for the cost of labor, pipework, insulation, and other extras when estimating the costs of building and installing a boiler room in addition to the boiler itself. The size of your home, the boiler type you select, and the difficulty of the installation are just a few examples of the variables that may affect these costs.

Getting quotes from several contractors is a good idea if you want to make sure the price is reasonable. But it’s also crucial to put quality and dependability ahead of just going with the cheapest option. A boiler room that is installed correctly can provide years of effective heating and hot water, but an installation that is done incorrectly can eventually result in more frequent breakdowns and higher maintenance costs.

The efficiency of your boiler room can also be greatly impacted by making an investment in appropriate insulation for your home. Reduced heat loss through floors, walls, and roofs will lighten the load on your boiler and save energy costs even more. Furthermore, adequate insulation can lessen the need for excessive heating by helping to maintain a more comfortable temperature throughout your house.

In conclusion, the long-term advantages in terms of energy savings, comfort, and dependability make the initial costs of building, installing, and plumbing a boiler room in a private home reasonable. You can make sure that your boiler room provides dependable and efficient heating for many years to come by carefully weighing your options, getting several quotes, and placing a high value on quality.
