The role of ventilation in a room with a gas boiler

In a gas boiler, oxygen air actively participates in the fuel combustion process. As a result, the amount of it in the boiler room rapidly decreases, the gas burns incompletely, which causes soot to more actively settle on the chimney’s walls and makes the space stuffy. Under such circumstances, a person’s health can rapidly decline and they may even lose consciousness.

If gas leaks from the house’s internal gas pipeline occur, things could get more complicated. The situation blows up, possibly with dire repercussions.

A ventilation system should be installed in every room containing gas devices to stop this from happening. Because of the infusion of fresh air from space and the extraction of contaminated materials, it enables continuous mode room refreshment.

Through wall-mounted ventilation holes, fresh air is brought into the boiler room.

Ventilation requirements in a private house with a gas boiler

Small-power gas boilers, up to 30 kW, are most frequently used in private homes. It is not necessary to have separate boiler rooms for their installation. These kinds of appliances can be installed in kitchens that satisfy the following criteria:

• The area of the room is more than 15 m 2;
• ceiling height of at least 2.2 m;
• The area of window openings is more than 3 cm 2 per 1 m 3 of the volume of the room. The window should be opened completely or to be equipped with a window;
• the presence of supply ventilation through the holes along the bottom of the door (4–5 holes with a diameter of at least 20 mm);
• the distance from the wall of non -combustible material to the boiler is at least 10 cm. It is allowed to install an additional cement-stove or metal sheet to cover the wall site next to the boiler.

You need to finish the non-combustible material on the wall next to the boiler.

The boiler installation site is subject to certain unique requirements in addition to the ventilation device. Boiler rooms are permitted to set up:

• in premises attached to the residential house;
• in separate buildings;
• in attics;
• in separate rooms in the house.

Boiler houses are frequently outfitted in a building’s basement. Devices that use liquefied gas are exempt from this. Because of its greater density than air, it can accumulate at the floor in the event of a leak, initially remaining invisible at the height of human growth. The atmosphere becomes explosive as a result.

Standardization of ventilation during operation of gas boilers

It is important to remember that gas equipment poses a higher risk. As such, the state has standardized the process for the construction and functioning of boiler houses, and it strictly monitors adherence to these regulations.

"Construction standards and rules 2 are applied and applied" in order to simplify all requirements.II-35 ", and II-35–76 on April 5. The preceding description covers the fundamental specifications for gas boiler premises.

Additionally, this document governs:

• the procedure for developing technical documentation;
• dimensions and power of ventilation systems for different types of buildings;
• Their types and procedure for arrangement.

How to arrange ventilation of a gas boiler in a private house

There are various kinds of ventilation available for spaces that have gas boilers:

• supply;
• exhaust;
• supply and exhaust;
• Natural.

Practically speaking, none of the listed species are used independently. Combinations of these techniques in different combinations yield the most effective ventilation strategies.

Natural supply ventilation

This is the most popular and required method of providing the boiler room with fresh air.

Air enters the room through the bottom input holes in the supply natural ventilation scheme and exits through the upper exhaust channels because

The ventilation duct is made by the following manufacturer:

1. Marking is made according to the diameter of the pipe with a margin of approximately 10 mm. The diameter of the duct pipe should be at least 15 cm.
2. The hole is drilled. You can use a drill with carbide attacks (for walls made of construction stone) or a special crown.

Using a perforator and crown or a drill along the contour, the ventilation canal hole is made.

A grill covers a portion of the ventilation pipe that exits into the street to keep out small animals and trash.

A ventilation duct’s output should be at least one meter away from the boiler when choosing a location for it to be installed so that cold air won’t interfere with the unit’s functionality. Modern automation can handle this situation with ease, of course, but there’s no need to overload it.

Although the effects of weather and other external factors on the natural ventilation channel’s ability to function should be considered, one of its undeniable benefits is that it will continue to function regardless of the mains, guaranteeing a steady supply of outside air.

Forced exhaust ventilation

Fans, filters, and callerifers make up the widely adjustable combined supply and exhaust systems. These are, in fact, climatic systems. Considering that contemporary boilers are outfitted with multiple regulators that autonomously regulate their operation based on the boiler room’s microclimate, employing these ventilation devices not only ensures optimal heating unit performance but also significantly reduces fuel consumption.

The operation of fans installed in the laid ducts provides and selects supply ventilation systems.

Channel and free ventilation systems

Ventilation systems are classified based on a number of factors, including their design and air movement mechanism.

Because of the building project, the channel ventilation system enables the construction or use of specially designed air ducts. Here, a number of niches, the suspended ceiling’s mounting area, and ventilation shafts are utilized. When such components are not included in the building’s design, the ventilation systems are installed directly on the walls and concealed by the room’s décor details.

The supply and exhaust ducts must be installed for the channel ventilation system.

It should be mentioned that a building’s ventilation cannot be solely taken into account for a single room, not even a boiler room. All airflows are combined into one system and either forced or naturally expelled from the home. Gas appliances are suitable for use in the living room (gas fireplace), bathroom (gas column), and kitchen (stove). The same standards apply to the air exchange principles in each of these objects.

Pipes are the primary means of moving air. Most well-liked:

• Rectangular products made of galvanized steel. They are convenient in installation, always provided with components of elements – angles, bouncers, etc. D.;
• Aluminum pipes corrugated. Practically do not require additional fittings, since they themselves are flexible products. It is quite convenient to work;
• plastic air ducts rectangular and round section.

The decorative lattices of the gear, connecting elements, and air intakes can be used to douche all of the aforementioned products. Because of their use, installing an air duct has become easy and reasonably priced, even for those without the necessary skills.

You can assemble a ventilator of any configuration with your hands thanks to the air ducts’ lightweight and compact components, as well as the availability of all the fasteners and connecting parts you need.

The steps involved in installing exhaust and supply ventilation in the boiler room by hand:

1. Punch holes in the wall to install air intake.
2. Install the pipe with a reverse slope into the hole, fix it with mounting foam.
3. Put on a safety net on the outer part of the air intake.
4. Connect the axial fan if the forced supply ventilation is installed. Mount the check valve.

The ventilator has a fan installed to regulate the room’s air supply.

Using an aerator that is mounted on the roof, the spent air is released from the building through the ventilation channel.

The calculation of the section of ventilation

The following information is required in order to accurately calculate the cross section of the boiler room ventilation system pipeline:

1. Cubature of the room of the boiler room depending on the height of the room. According to the requirements of SNiP, its height should not be less than 6 meters. It is obvious that in a village house such a requirement is impossible. When calculating, it should be borne in mind that when this indicator is reduced by 1 meter, the amount of air required for combustion of fuel should be increased by 25%;
2. Air flow rate (at least 1 m/s).
3. The frequency of air metabolism. The value depending on the height of the room of the boiler room.

The computation’s output will be the amount of air required, from which the ventilation system’s pipeline segment can be identified using specific tables.

The formula V = L x S X (6 – H) x 1.25 x N is used in the computation, where:

Therefore, the actual size of the room and the increase in air turnover are taken into consideration when determining the need for air. Once the required value has been obtained, the duct’s diameter can be chosen from the table.

For ventilation with gas devices, it is best to set up a redundant ventilation system so that at least one of them functions.

When the electricity is turned off, the building will be naturally ventilated using its natural circulation routes.
