Heating diagram for a private house with a gas boiler

A comfortable private home should have comfortable heating. Even during the design process, it is necessary to lay out and think through the layout of the heating systems. Gas heating is often chosen as heating. Since this heating system reliably and efficiently heats the entire room.

Which heating scheme with a gas boiler is best suited for a cottage or private house?

When you plan to arrange the entire system without the help of professionals, you need to calculate the heating circuit.

There are two types of gas heating circulation:

• forced circulation is produced thanks to pumps;
• natural produces movement due to the difference in the densities of hot and cold water.

IMPORTANT. Natural works better when installing equipment at a lower level relative to radiators.For stable movement of the coolant, you need to make a natural slope of the pipelines.

With an artificial one, it is possible to install a pump. Installation is simple, but the pump with artificial circulation has disadvantages: uneven heating, dependence on electricity and the possible appearance of air locks.

Heating distribution is:

1. Single-pipe. Suitable for a not too large area with a small number of rooms; when using this wiring, the temperature in the pipes varies.
2. Two-pipe. Difficult to implement, suitable for adjusting the temperature in different rooms.

ATTENTION. When using single-pipe wiring, a big disadvantage is revealed: the lower part of the radiator does not heat up well. Radiators will warm up differently on different floors of the house. This problem can be solved by installing jumpers to the batteries and increasing the capacity of the batteries. It is also recommended to install pumps to ensure sufficient coolant movement.

The advantage is the easy installation of wiring, which you can do yourself. During installation, a small amount of materials is consumed, which is also a plus.

Two-pipe distribution heats the pipes evenly. However, it requires a large amount of material for installation and pipe laying. The advantage of two-pipe wiring is the ability to regulate the pipes using shut-off valves.

REFERENCE. There is also a Leningrad wiring. A pipe is connected to it, which circulates liquid in parallel. This system is suitable for furnishing a cottage or private home.

The optimal option for arranging equipment in the basement would be a two-pipe distribution with natural circulation.

Standards for installing a gas boiler in a private house

Installation of equipment is carried out by employees of the gas organization. There are official requirements that must be met when installing equipment in a cottage. Such documentation includes:

• SNiP "Gas distribution systems".
• SNiP “Gas Supply” does not contain mandatory requirements, however, it will help you understand the installation.
• In addition to these requirements, there are a number of necessary rules described in SNiP.

According to official regulatory documents, setting up a gas boiler is allowed in the basement, on the basement of the house.

Safety measures and precautions for installing a double-circuit gas boiler in a private house

It follows from the rules that when setting up gas appliances in a cottage, the room for the boiler room must meet the following parameters:

• room area - 4 m²;
• the entrance opening to the room is 80 centimeters wide;
• lighting, natural as well as artificial light; window - from 30 square meters;
• ceiling - two and a half meters;
• a grounding loop is required for installation;
• a cold water pipe is required for installation;
• the chimney must be proportionate to the power of the device;
• The walls need to be leveled.

Therefore, dual-circuit appliances should be installed in the kitchen. Since the kitchen has a layout that meets all safety requirements and regulations. Wall-mounted appliances are best suited for the kitchen, as they can be easily placed in the room and will solve the problem of connecting cold and hot water. And to install a floor-standing device, an additional room or boiler room is required.

For a wooden house, all requirements and standards remain the same. But there are a number of nuances that need to be observed:

• If the power of the device is approximately sixty kilowatts, then the space required is more than 27 square meters. Units less than 60 kW can be installed in the kitchen, but the installation must meet all requirements.
• If the power of the device is not more than 150 kW, then the unit should be installed in a separate room.
• As for the first option, for the second the walls in the room where the equipment is installed must be protected from temperature changes.

How to install a gas boiler in a private house

Installation of boilers always begins with the preparation of relevant documents and the conclusion of an agreement for the supply of gas to a private house. After this, you need to contact the appropriate organization and obtain consent for gasification and installation of equipment.

Installation and connection of a gas boiler

There are only two types: floor-standing and wall-mounted boilers. Installation of devices differs slightly.

Installation of wall equipment:

1. we protect the wall on which the unit will be located in advance with fireproof material;
2. when preparing the apparatus, it is necessary to clean the walls of the inlet pipes from debris and dust under high pressure of water;
3. install a filter and shut-off valves on the water supply pipe;
4. installing a chimney;
5. checking traction;
6. Next, you need to insert the unit into the gas pipeline; this work is best left to gas service workers;
7. connect the device to the power supply.

Procedure for installing floor-standing equipment:

1. it is necessary to build a strong pedestal that can support the weight of the unit;
2. level the gas equipment using a level;
3. connect the equipment to the chimney, test the draft;
4. connect the device to the heating system of the house;
5. install a filter that will protect against blockages;
6. you need to connect the unit to the water supply;
7. Cutting out the gas apparatus to the main line is best done by gas service workers.

Grounding a double-circuit gas boiler in a private house

Before performing grounding, it is necessary to select a grounding conductor; there are artificial and natural grounding conductors. Grounding a double-circuit boiler is a complex process, in which you need to check the equipment resistance and soil conductivity in advance. Grounding consists of a number of actions:

1. You need to dig a rectangular groove in the ground, 35–40 cm wide, 50 cm deep.
2. Drill holes at the corners of the ditch.
3. Drive corners 60 millimeters wide and 3 meters long into the pits.
4. Scald the triangle with a 4 cm strip, stretch the same strip from the ditch to the house.
5. Weld a spire onto the end of the strip and attach a ten-centimeter spire to the base of the building.
6. Ground from the spire to the gas equipment.

Grounding guarantees the safety of using the gas boiler.

The nuances of installing a wall-mounted gas boiler

The wall-mounted device must be free of dents, signs of damage and repairs. If a gas boiler has external defects, you should contact the store where it was purchased.

The chimney for a wall-mounted boiler must meet certain standards:

• in diameter not less than the required one, which is specified in the instructions for the device;
• identical cross-section of the chimney and the opening of the device;
• the height of the chimney must be more than 5000 mm above the roof;
• For a wall-mounted boiler, it is recommended to purchase a cylindrical chimney.

Wall-mounted boiler piping

The necessary piping guarantees the long-term service of the boiler. There is a direct and mixing method for tying a wall-mounted boiler. It involves an emergency strapping method, which is divided into:

• water supply source - water supply;
• gravitational circulation;
• power supply from UPS;
• emergency circuit.

The nuances of installing a floor-standing gas boiler

When installing the device, three outlets must be installed inside the chimney, throughout it. And the length of the pipe that connects the boiler and the chimney should be around 25 cm.

You need to choose the correct position of the floor-standing boiler for ease of repair in the future. Also, shut-off valves and valves must be installed in each line of the boiler, which will allow it to be removed without draining the coolant from the entire system.

Wiring diagram for floor equipment

Floor-standing equipment is capable of heating a large space. Installation of this equipment is more complicated and expensive, as is its wiring diagram. It is more complicated, since the floor equipment comes together with the security group. And that is why it is necessary to independently mount the pump and expansion tank.

Floor-standing boiler piping schemes are divided into two types:

• with a jumper: the sensors are located outside, and a pump is mounted in place of the jumper;
• with three-way valve.

What is important to know for constructing a heating circuit and connecting a gas boiler in a private house

When choosing a gas heating system as a heating system. You need to know that when connecting and designing a heating circuit, you need approval from government organizations. This is necessary to comply with safety regulations. When constructing a diagram, you need to start from the selected gas boiler model. The best option is a two-pipe boiler, but its installation and installation requires the help of employees of the gas organization that supplies gas to the house.
