Installation of a double -circuit gas boiler in a private house

Are you thinking of replacing your house’s heating system? Putting in a double-circuit gas boiler in your home could completely alter your situation. This cutting-edge heating solution keeps your space warm during the cold months while supplying hot water for your household’s needs.

For homeowners, finding a cost-effective heating solution is essential due to the rising cost of energy. Natural gas, which is less expensive than electricity or oil, powers a double-circuit gas boiler. These boilers use the power of gas to heat your house and water effectively and economically.

The adaptability of a double-circuit gas boiler is one of its main advantages. Double-circuit boilers have a separate circuit for hot water, in contrast to single-circuit boilers, which only heat. Because of this, you can take advantage of a constant supply of hot water for baths, showers, and household tasks without sacrificing heating efficiency.

Worried about the effects on the environment? When compared to other heating options, double-circuit gas boilers are renowned for having a comparatively low carbon footprint. Modern gas boilers are engineered to reduce emissions thanks to technological advancements, which makes them a more environmentally friendly option for homeowners who care about the environment.

It is crucial to evaluate the hot water and heating requirements of your house before beginning the installation process. Determining the ideal boiler model and size for your home can be facilitated by speaking with a qualified heating technician. Over time, proper sizing will save you money by ensuring peak performance and energy efficiency.

Installation of a double -circuit gas boiler – recommendations, instructions

Today, gas boilers and speakers are used everywhere both for heating water and for heating houses. For the most part, separate single -circuit boilers or one single -circuit boiler and an indirect heating boiler are used for heating and hot water supply, which creates certain inconvenience in their placement. Therefore, in houses and apartments with small consumption of hot water, the installation of double -circuit gas boilers is gaining more popularity, combining water heating, both for household needs and for heating. The installation of gas boilers is associated with a number of certain difficulties, related to a greater extent in compliance with the norms and requirements for boilers than with the process of their installation.

Double -circuit boiler device

Dual-circuit gas boilers are designed similarly to standard single-circuit boilers, in which the coolant-heated heat exchanger is heated by the gas burner. The primary distinction is the ability of double-circuit boilers to simultaneously heat water for domestic needs and house heating. This is made possible by the heat exchanger’s pipes for hot water supply and heating being placed in tandem.

At first glance, the heat exchanger of a double -circuit boiler is an ordinary coil with a radiator grill. But it should be noted the following, the coil of a double -circuit boiler most often is a combination of pipes 2 in 1. Another one is placed inside the main pipe, along which water for heating flows, for hot water supply. In this case, it should be noted another very important point. Water in such a double heat exchanger circulates in opposite directions in each contours. This was done specifically to improve heat transfer and this must be taken into account when designing and connecting a water supply and heating system to a dual -circuit boiler.

The number of connected pipes had an impact on the existence of two heating contours. As opposed to a single circuit, which had a single gas supply and three pipes for driving and supplying water. A double-circuit boiler comprises five of these pipes. The double-circuit diagram of the gas boiler shows the following (from right to left):

  • a pipe with an incoming coolant for heating;
  • supply pipe for hot water supply;
  • pipe supplying gas;
  • pipe with outgoing hot water for water supply;
  • Pipe with outgoing coolant for heating.

Crucial! Examine the instructions carefully before connecting your own boiler using the above scheme. It’s possible that your boiler’s connection will be made slightly differently. For instance, the supply pipes come from the left and are both on the right side.

It’s also important to note that wall-mounted and floor models of double-circuit gas boilers are currently available. Apart from their installation methods, the floor and wall differ in that the floor needs a dedicated boiler room, whereas the wall can be installed in the kitchen or in the boiler’s designated space. We’ll talk more about where and how to install gas heating boilers later.

Norms and requirements for the installation of gas boilers

The installation and connection of a double-circuit gas boiler can only be carried out by specialized organizations that possess the necessary authorization and license. Reservations must be made immediately. There are hefty penalties associated with independent installation and connection. However, some work related to getting ready for the boiler connection and designing the required permits will still need to be done on your own.

Apart from the fundamental regulatory documents, such as SNiP 42-01-2002 "Gas distribution systems" and SNiP II-35-76 "Bolen Instances," which contain guidelines for the design of autonomous heat supply systems SP-41-104 -2000, the following recommendations and rules apply. The specifics of what can and cannot be done when installing gas equipment are outlined in these regulatory documents. We’ll talk about the most crucial specifications for installing gas boilers.

1. The gas boiler installation space must have a minimum floor area of 4 m2 and a minimum ceiling height of 2.5 m.

2. The room’s doorway needs to be at least 80 centimeters wide;

3. There ought to be windows open on the property. The following specifications are used to determine the window’s size: 0.3 m2 of area per 10 m^ of area;

4. To guarantee continuous gas burning, the room must have excellent ventilation. 8 cm2 of opening space should be available for every kW of boiler power. This also holds true for boilers with closed combustion chambers, which combine the functions of combustion removal and product supply into the boiler through the use of coaxial chimneys;

5. The diameter of the chimney is determined using a specific formula and chosen based on the boiler’s power. Boilers with a power output of between 30 and 40 kW are typically used to heat homes. Chimneys measuring 130 mm and 170 mm in diameter are thus installed;

6. The chimney’s upper end should stick out 50 centimeters above the roof skate. When using a coaxial chimney, make sure the withdrawing end is at least 20 cm away from the air intake;

7. Metal pipes should be used for the home’s gas pipeline. But you can use flexible corrugated pipes to connect the boiler to the highway;

8. The boiler needs to have a unique automatic thermal and current protection system;

9. A gas analyzer ought to be installed in the building housing the boiler;

10. Only private homes are permitted to install gas boilers in their basements. Gas boilers can only be installed in kitchens or boiler rooms that are specifically designated for this purpose in apartment buildings.

11. Every boiler needs to have a gas meter installed;

12. A cold water pipeline is necessary in the room;

13. The walls in the space where the boiler will be installed need to be plastered and leveled;

14. It is not permitted to install boilers in basements of apartment buildings, on combustible surfaces, in hallways, restrooms, hostels, balconies, and rooms without windows;

15. The boiler needs to be positioned at least 15 centimeters away from the wall. There should be a minimum of 20 centimeters between the top of the chimney and the ceiling. The chimney’s exterior should extend thirty centimeters beyond the house’s wall. A thermal insulation panel needs to be positioned between the wall and the boiler, and the installation height for a hinged boiler should be between 0.8 and 1 m from the floor.

Crucial! If the boiler is a double-circuit model with a closed combustion chamber, then having windows in the room is not required.

It’s easy to obtain permission to install a double-circuit boiler at home if you follow these straightforward guidelines. Of course, since the aforementioned guidelines are broad and specific cases may require different restrictions, familiarizing oneself with the SNiP will not be unnecessary.

Coordination of the attitude in the authorities

The challenges associated with installing double-circuit boilers don’t end with SNiP compliance. The majority of the time will be needed to arrange for the installation and obtain the required permits. In order to get approval, you need to do the following:

1. You need to obtain the technical requirements for connection before connecting a private home or apartment to the urban gas supply. We write a statement in the city gas service to accomplish this. The estimated amount of gas used per hour needs to be specified in the application. It will require a week or two to process your application. The technical installation conditions will then be placed in your hands.

2. After obtaining technical requirements, a project to supply gas must be developed. This is actually the connection points, gas pipeline laying, and boiler installation diagram. The gas communications laying scheme for the site is also included in the private house. Design engineers licensed in gas communications are working on the project in a specialized bureau. Gorgaz makes it simple to find the contact details of design firms.

3. The project is sent to Gorgaz or another capable service (Raigaz, Oblgaz, Mingaz) after it has been created and refined. Reaching an agreement on a project could take a week or three months. The length of the approval process is determined by how complicated the project is. In addition to the project, the following related documents must be submitted:

  • Coiler registration certificate;
  • instructions for its operation;
  • certificate of compliance with technical and sanitary requirements;
  • the conclusions of the examination for compliance with the boiler with all the necessary requirements.

When purchasing a boiler, it is crucial to confirm the availability of these documents as they are supplied by the manufacturer with the boiler.

Naturally, there is always the option to deviate from the project. In this instance, you must receive an official document outlining the project’s modifications as well as the reasons for the rejection. You will be granted permission to install the boiler once the revisions and re-application for approval are completed.

Installation of a double -circuit gas boiler

After determining the location for a double-circuit gas boiler installation and connecting it to the hot water supply and heating system, you can move on to installing the boiler itself. It is imperative that a reservation be made immediately because the same materials and components will be needed for installation and strapping whether the boiler is mounted on a wall or on a floor. A general list of what will be needed for dependable operation is provided below:

  • Ball Valves;
  • coarse filter;
  • magnetic filter;
  • mesh filter;
  • gas filter;
  • Drills;
  • flexible corrugated hose;
  • manometer;
  • thermal regulator;
  • coaxial chimney;
  • Surproser valve for 3 bar.

Crucial! The gas boiler’s connection diagram determines the quantity and equipment of related materials.

Gas boilers with dual circuits are installed in nearly all rooms that are approved for them. Its installation can be done on your own, but connecting gas equipment directly requires a specialist who has the necessary certification to do this kind of work. There will be fines for the boiler being self-connected.

Setting up a location for the installation of a double-circuit gas boiler comes before connecting it. This primarily relates to the provision of pipes for heating and hot water, as well as the drilling of chimney openings and the application of refractory wall covering. When everything is prepared, we start the boiler installation process:

1. Cleaning the boiler pipes system will be the first step in removing any potential dirt particles that may have entered during boiler assembly at the factory. Next, we replaced the previously removed plugs on them.

2. Special strips that are included are used to attach the wall boiler. The wall boiler installation height should be between 0.8 and 1 m from the ground. Drill holes in the wall beneath the bar and fasten them with self-tapping screws. Use anchors for dependability in place of self-tapping screws.

Crucial! It is imperative to keep an eye on the planks that have been installed. This determines where the boiler should be placed. The boiler heating system can quickly fail due to even the smallest skew.

3. Mount the boiler using the fasteners. Verify the exact value of it. We make the necessary corrections and fixes.

4. We locate the incoming pipes and connect them to ball valves before filtering the water to remove either fine or rough particles. This will enable you to clean and wash filters throughout the system when needed.

5. After that, attach the ball valves to the input and output. Their availability is required because the boiler, hydraulic area, and heating systems all greatly benefit from their upkeep and repair.

6. Installing the drives will be the next action. They are the ones who will attach the boiler to the hot water and heating system pipes.

Crucial! We keep our hands off the gas supply pipe. A specialist from a gas company with authorization to perform such work will install a meter, valves, and handle its connection and crimping.

7. Next, we attach the heating system. In order to get rid of the scale and salt from the boiler, you must first rinse it multiple times if it is connected to the old system.

8. We integrate the updates to the boiler’s heating pipe. Installing a circulation pump between the burning and the pipe is an option if needed.

Crucial! We ensure that the direction of water movement from the system to the boiler is indicated by the arrows on the taps, drives, and filters.

8. Finishing the outgoing pipe connection from the boiler to the heating system is the process of connecting to the heating system. In the meantime, we ensure that the fittings’ water movement direction matches reality.

9. Turn on the hot water supply. With the exception of placing a thin cleaning filter or a magnetic filter in place of a rough cleaning filter, all operations are actually the same as connecting heating.

10. We fasten the boiler to the chimney. To accomplish this, a chimney pipe is started into the hole that has already been prepared, and it is then connected to the boiler’s chimney fitting through the knee.

Crucial! If you purchased a boiler with an open combustion chamber, the chimney pipe needs to meet the requirements listed below:

  • the pipe should be made of metal resistant to the acidic environment;
  • The chimney is excreted above the skate of the house;
  • A hatch for cleaning should be mounted in the chimney itself;
  • The chimney itself should consist of no more than three knees;
  • Parts of the chimney from the boiler to the street should not exceed 25 cm.

The boiler gas double-circuit flooring is installed in the manner described. The main distinction in installing a floor boiler is the creation of a dedicated room beneath it, complete with walls and floor equipped with fire protection. Furthermore, the boiler is typically fixed to the floor rather than mounted to the wall using brackets.

It is still necessary to wait for the double-circuit boiler to be connected to a gas pipe and turned on after installation is complete. This phase of the boiler installation is carried out by a gas company specialist. It should be mentioned that you should ask the masters for assistance if you have never completed this kind of work before. All of the work will, of course, come at a penny, but the connected boiler will also be far more reliable and secure.

Articles on the topic

This post will discuss installing a double-circuit gas boiler in a private home, outlining the advantages and important procedures. A double-circuit gas boiler is a flexible and effective option for homeowners as it can meet their needs for both hot water and heating. A suitable boiler size must be chosen, the house’s heating needs must be evaluated, and safety precautions and adequate ventilation must be guaranteed. For maximum performance and safety, professional installation is also essential. Installing a double-circuit gas boiler can help homeowners save money on energy bills and lessen their environmental effect while providing a dependable source of hot water and heating.

DIY gas boiler installation

Natural gas boilers have been used more frequently recently to heat country homes. Their basic operation involves heating the coolant. Gas boilers have several benefits, including being quiet, small, easy to operate, and suitable for installation in a private residence.

The boiler’s efficiency determines how heated the entire house is. However, since gas, which is used as a coolant, is a highly explosive material, care should be taken when selecting this equipment. Additionally, when installing a gas boiler, follow current regulations.

Installing a gas boiler on your own is a responsible, time-consuming, and complex task. The required certificates are given to employees of gas supply companies; their presence, however, only permits direct access to the gas pipeline.

And the capable and diligent individual can succeed! Furthermore, connecting electricity, supplying water, and installing the boiler are tasks that practically any man can handle.

Furthermore, installing heating equipment on your own can save a lot of money.

Introductory video instruction manual

Basic species

Gas boilers are categorized based on a number of indicators, including installation technique, power output, traction type, and purpose. Boilers with single circuits are installed solely for the purpose of heating the house; double circuits enable the provision of water for heating as well as the warming of the premises.

Medium-sized aggregates in a two-stage boiler operate on a single-stage principle of adjustment for low-power boilers. Typically, modulated power adjustment is offered by high-performance boilers.

Boilers of the closed-type operate on ventilation thrust. Additionally, open-type or atmospheric gas boilers with natural traction are available.

Gas boiler installation can be done on the floor or on the wall of a private residence. Heat exchangers made of copper are used in the first scenario, and steel or cast iron in the second.

A flowing double-circuit boiler that runs on automation is the best option for use in a private home. In addition to heating water for cooking, dishwashing, and showering, it provides heating for the building during the winter.

The automatic system, which has a microprocessor and two thermostats, makes it much easier to operate the equipment. It also lets you monitor the temperature inside the rooms and outside, and it can be programmed to turn down the heating when no one is home, such as during the day when everyone has left for work.

When compared to equipment with manual or semi-automatic control, installing a boiler with fully automatic control can help you save anywhere between 30% and 70% on fuel.

However, without electricity, an automatic home boiler room will not be able to heat the entire house, so circumstances pertaining to force majeure must be covered while the boiler is being installed.

Make sure a complete set and a certificate are present when purchasing a gas boiler. Buy additional fasteners if needed to install the unit on the wall.

Requirements and rules for installing a gas boiler

You can mount a basic gas heating boiler by yourself. Complicated equipment should only be connected to specialists. Furthermore, there are specific installation guidelines that apply to both basic devices and gas systems that use DIS.

In particular, combustion products can only pass through three bends or pipe turns, and exhaust should be directed to a separate vertical gas wrap (not the chimney!). The chimney’s horizontal section should not be longer than 3 meters, and the pipe connecting the chimney to the boiler should not be longer than 25 centimeters.

The requirement for the premises

Additionally, the location of the boiler room or furnace—where gas equipment will be installed—must meet specific regulations. These specifications are pretty stringent. However, non-compliance will result in penalties from the auditing bodies, and observance will help avert mishaps because gas is a flammable and explosive material that requires extreme caution when handling.

A gas boiler can be placed in a kitchen, basement, closet, or special addition that has a hood and ventilation. Mounting gas equipment in the living room, bathroom, or toilet is also strictly prohibited. The remaining specifications vary based on the boiler type.

Therefore, all rooms in the house may install a low-power single-circuit boiler up to 60 kW, with the exception of the ones mentioned above. It is not possible to install double-circuit boilers in kitchens.

The room where the equipment will be installed can be on any floor of the house as long as its total capacity is within 150 kW. Only the first and basement floors of a private home may be equipped with more powerful gas boilers and equipment (150–350 kW).

The boiler room must be 0.2 m3 in size for every 1 kW of equipment power at a ceiling height of 2.5 m, but not less than 15 m3 of the total volume, according to the regulations for installing a gas boiler.

A minimum of 0.75 hours should be the fire resistance limit for walls. It is not appropriate to install a false floor and false trip. All devices and auxiliary equipment must have easy access in order to be regulated, maintained, and charged.

The boiler room must also get natural light. In order to achieve this, a window must be built in the space at a rate of 0.03 m2 of opening area for every 1 m3 of boiler room volume. A window has to be present in the window.

The boiler room door must be at least 80 cm wide in order to meet certain requirements. Be aware that the width of the door leaf—not the opening—is being discussed here.

Furthermore, you must install a ventilation grille or leave a tiny opening in the lower portion of the door. Additionally, a ventilation grill can be built into the wall next to the room beyond. Based on the boiler’s power, the ventilation production section is computed at 8 cm2 for every 1 kW.

A second exit to the street should be installed in the boiler room if the gas boiler is situated in the basement. If the gas boiler is installed in the addition, it should be placed close to the residential building’s deaf wall, no more than 4 meters away from the closest window, and 8 meters above the overlap (SNiP 41-01-2003 and MDS 41-2.2000).

Drawings and installation circuits of a gas boiler

A few installation circuits for the gas boiler and associated equipment are shown below.

  1. General scheme for installing a gas boiler with a DHW system.

  • Binding diagram of a double -circuit gas boiler.
  • Card of a boiler strapping in an open system. More information can be found in the instructions that are attached to each device.

DIY installation (installation) process

The installation of gas boilers in a private house begins with the paperwork and ends with a chimney device. First you need to conclude an agreement on the supply of natural gas to your house. Then you should contact a gas -filling enterprise and get a project of gasification of the house and the installation of gas equipment with a boiler strapping scheme . The simplest boiler, the so -called "water heater" consists of a gas burner and heat exchanger. Water and gas are connected to it, and the exhaust is displayed into the chimney. But even the installation of such a simplest system requires obtaining the appropriate permission! Let us consider in detail the installation process of the wall and floor gas boiler of a more complex structure. Installation of a wall boiler

  1. We protect the section of the wall where the boiler will be located, a layer of refractory material, leaving a gap of 4.5 cm between it and the wall.
  2. Prepare the boiler for installation. Under the high pressure of the water, we clean the walls of the inlet tubes from small litter remaining after assembly.
  3. Install the filter and shut -off valves on the pipe for water supply – before and after the filter.
  4. We mount the chimney. Certain requirements are also imposed on this device: the diameter is no less than indicated in the guide to the gas boiler; The section is similar to the boiler chimney; Anti of the roof skate is not less than 0.5 m (section 6 SNiP 41-01-2003, section 4 and Appendix 6 MDS 40-2.2000). It is best to use a steel cylindrical chimney with a cleaning hole.
  5. Check traction. In case of its deterioration, the automation, which modern boilers are equipped, must stop supplying gas.
  6. Using a steel pipe and a special capacity, for its installation, we insert the boiler into the gas pipeline. To carry out this work, it is necessary to invite gas service specialists.
  7. Connect the gas boiler to the power supply and connect an automatic device to protect against overload.

Maybe you would also find an article about selecting a heating coolant interesting.

Putting in a floor boiler

  1. We build a strong pedestal that can withstand the severity of a cast -iron boiler. In the extension for this, pour the concrete screed, in other rooms on the wooden floor we put a piece of galvanized sheet gland.
  2. Install a gas boiler with our own hands, controlling its position using the level.
  3. We connect the boiler to the chimney and, if it is not equipped with a forced exhaust, check the traction.
  4. Connect the boiler with the intra -domestic heating system. At the same time, to protect the unit from blockages, we install a coarse cleaning filter, placing it after a drive line filling the system with water, before entering the back line boiler.
  5. We attach a double -circuit boiler to the water supply, performing the insert closer to the house, before the start of the branching.
  6. Using a steel pipe, we insert the boiler into the gas line, as in the previous case, with the participation of specialists.

Operation Rules

However, just like in other establishments, gas boilers can only be installed and used in dry rooms in private homes. Elevated relative humidity hinders the airborne dispersal of foreign materials, such as gas vapor. As a result, the regulations governing the installation of gas boilers are much stricter than those governing combustion boilers (see. higher).

Using a coarse cleaning filter to shield the heat exchanger from dust and debris is essential to maximizing its efficiency. Filters are another essential tool for raising the quality of water.

Gas equipment should be maintained either before the heating season begins or at its conclusion. And this needs to be done on a regular basis to prevent dangerous situations!


During the maintenance process, the system as a whole, the filters are cleaned and washed, and the condition of the chimney and ventilation system are assessed. Use detergents that efficiently remove different types of deposits to accomplish this.

Remember to keep the burner clean. We guarantee that worn-out components will be replaced! Make sure that all of the connections are tight before powering on the system.

The system’s service life will be extended while fuel consumption is decreased through adherence to established standards, skillful gas boiler connection, rule-abiding operation, and prompt maintenance.

How to install a double -circuit gas boiler in a private house

  • Preparatory work
  • Implementation of installation work
  • Creating ventilation and launching equipment

Different types of gas equipment In a private home, a double-circuit gas boiler will become essential for both heating and hot water use. This equipment comes in two primary varieties: one with a boiler and the other without one. The way they operate is determined by how much hot water is used.

The quick heating of the water provided by a double-circuit boiler is its convenience. One such boiler can raise the temperature of six liters of water to 37 degrees in just one minute.

When the amount of water heated to thirty degrees Celsius is less than fifteen liters per minute, a running gas boiler is installed. The boiler that has an integrated boiler ensures that there is always hot water in at least 50 liters.

A double-circuit boiler could be any of the following, depending on how the burning gas is removed:

  • chimney (withdrawal of combustion products into the pipe);
  • condensation (removal of condensate in a sealed chimney);
  • turbocharged (a fan is used in the chimney).

Additionally, there is a boiler unit for wall and floor products. Many people favor the final option. First off, using a wall gas boiler is thought to be more practical in both private homes and apartments. Thermostat connections are supported. Second, every component of the heating system is present in the boiler:

  • expansion tank;
  • firebox;
  • pump for air circulation;
  • protective reinforcement;
  • electronic control unit.

The following are the key benefits of utilizing a wall-mounted heating boiler:

  • efficiency of fuel consumption;
  • ease of installation (due to the small mass and compactness) and maintenance;
  • silent work (achieved due to the hydraulic system);
  • the possibility of connecting with other external devices;
  • installation anywhere at home or beyond.

Preparatory work

Setting up a gas boiler.

What is needed to install a gas boiler is:

  • boiler;
  • Ball Valves;
  • pipeline;
  • hacksaw;
  • anchors;
  • Americans;
  • filters (gas, magnetic, rough water purification);
  • gaskets;
  • FUM-love;
  • sealant;
  • clamps;
  • Bolts with washers of engravers;
  • drill;
  • pipes;
  • file;
  • chisel;
  • roulette;
  • level;
  • burner;
  • set of keys (wretched, end and divorce);
  • Screwers.

Diagram showing how a double-circuit gas boiler is bound.

The wall gas boiler’s connection diagram must first be created. The installation of equipment with your own hands will be aided by preliminary equipment wrestling. Based on the forced circulation principle, the heating scheme considers several objective criteria, including:

  • location of the boiler;
  • compatibility parameters for size in size;
  • The location of water supply, heating and gas supply systems.

Filters and ball cranes are essential components of a gas boiler. Heating pipes are not directly connected to the boiler. The American’s collapsible nuts serve as a sort of middleman.

This connection method makes it simple to remove the boiler for repair (or replacement) or to turn it off from the heating system without having to drain the water.

Hydraulic strapping diagram for gas boiler.

Ball taps must be installed properly for the boiler in the home to function efficiently for an extended length of time. They belong in every configuration of the trunk:

  • on cold and hot water;
  • on the feed, “return” and draining of heating pipes;
  • Signs and filters.

Different threads are used in the connection diagram (image 3) between cranes and pipelines: both with two internal (BB) and external and internal (VN). Apart from their primary functional "responsibilities" (coolant supply), ball valves assist in the following areas:

  • drop pressure in the water supply system;
  • check and flushing the highways;
  • carry out water drainage in winter during repair.

An apparatus for gas boilers.

One issue is actually resolved by strapping the boiler with ball valves, which enable you to disconnect the boiler and filters from the heating system. You can easily clean these components by shutting off the taps.

The development of a filtration system is required to stop the entry of different particles that could cause the machinery to malfunction. A wall gas boiler’s strapping invariably makes it possible to install a coarse cleaning filter. He collects sizable sand, rust, and warden particles that travel with water from the water system on his way to the boiler.

On a return pipe that has been heated down a nut, a coarse cleaning filter is installed. Many will wonder why the filter is installed on the "return" pipe rather than the feed pipe. The circulation pump in the boiler is located precisely on this pipe, which explains this. Thus, the installed filter simultaneously safeguards the boiler and the pump.

Two additional filters, one magnetic and one gas, are part of the double-circuit heating boiler installation plan. Gas revenge is caused by scale, which forms when water is heated. The magnetic filter shields the equipment’s heat exchanger from this risk. Scale frequently disables both the boiler and itself. On a pipe that receives cold water, the filter is installed prior to heating apparatus.

Gas is cleaned of dust, scale, rust, and resin particles by the system’s strain when it is equipped with a gas filter. Two filters must be installed on the boiler’s two sides. The gas equipment’s operating time is significantly extended by this procedure.

Implementation of installation work

Prerequisites for setting up a heating boiler.

Choosing the type of installation is the first step in installing any heating device in the home. Ten millimeter thick standard anchors are used to mount the wall boiler. Their length is determined by the weight of the boiler and the material used to build the wall.

The floor boiler is situated on a concrete podium that is 80–150 mm above the floor’s overall level. Installing boilers at the place of operation generally requires that they be placed strictly horizontally. The catwalk’s height can be decreased if the boiler has legs. Ignore the rules and don’t smile down at the ground.

Two pipes are located at the rear of the boiler to connect the heating system. Both pipe and metric threads are possible for the pipes. connecting the accuracy with flange components. After winding one side of the flange around the boiler’s bell (necessarily in the order feed to feed, return to return), the threaded connection is sealed. You can apply it to obtain it:

  • carving coating with a heat -resistant sealant;
  • winding on it of the FUM-tall of large thickness;
  • Application of paint.

The flange is covered with a sealing gasket. Welded joints, paronite, and textolite should be disregarded. Installing an oil-resistant rubber or cork laying will yield the best results. This will improve the material’s flexibility, heat resistance, and resistance to early drying and cracking.

Bolts with puck-grave connections hold the flange together. Their tightening is executed with extreme precision. It is required to fill the boiler after connecting it to the system in order to verify that all of the connections are tight. Two holes on the dual-circuit boiler diagram are intended for the supply of hot water and are used for both lifting and removing water. Their sizes can differ. The holes typically range in diameter from ¼ to 2.5 inches (adapters can be used to remove the required size). As a result, the material chosen for the water input/output is contingent upon the boiler type.

Go back to the contents table.

Step Description
1 Choose a suitable location for the boiler installation, preferably near the existing gas supply and water pipes.
2 Ensure proper ventilation in the installation area to prevent gas buildup and ensure safe operation.
3 Shut off the gas supply to the house before starting any installation work.
4 Install brackets or a mounting frame securely on the wall to support the boiler.
5 Connect the gas supply pipe to the boiler inlet using appropriate fittings and ensure it is securely sealed to prevent gas leaks.
6 Connect the water pipes to the boiler, ensuring the correct connection of the hot water and heating circuits.
7 Install a flue pipe to safely exhaust combustion gases outside the house.
8 Connect the boiler to the electrical supply and ensure proper grounding to prevent electrical hazards.
9 Fill the heating system with water and purge any air to ensure proper circulation.
10 Test the boiler for proper operation and ensure all safety features are functioning correctly.

When it comes to insulation and heating in your private home, installing a double-circuit gas boiler can make all the difference. It offers efficiency and convenience in one package since it can heat and provide hot water.
