Heating scheme of a private house with a gas boiler

A comfortable private house should have comfortable heating. Even during the design, it is necessary to lay down, think over the scheme of heating systems. As heating, gas heating is more often chosen. Since this heating system is reliable, it effectively heats the entire room.

What heating scheme with a gas boiler is best for a cottage or a private house

When you plan to equip the entire system without the help of professionals, you need to make a calculation of the heating circuit.

There are two types of gas heating circulation:

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

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

In the artificial installation of the pump is possible. Installation is simple, but the pump during artificial circulation has drawbacks: uneven heating, dependence on electricity and the possible occurrence of air jams.

Wiring heating is:

  1. Single tube. 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. It is difficult to implement, suitable for adjusting the temperature in different rooms.

ATTENTION. When operating a single-pipe wiring, a big minus is revealed: the lower part of the radiator does not heat up well. Radiators will heat up differently on different floors in the house. This problem can be solved by installing jumpers on the batteries, to increase the battery capacity. Also, for sufficient movement of the coolant, it is recommended to install pumps.

The advantage is an easy wiring setup that you can do yourself. During installation, a small amount of materials is expended, which is also a plus.

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

REFERENCE. There is also a Leningrad wiring. A pipe is attached to it, which circulates the fluid in parallel. This system is suitable for arranging a cottage or a private house.

The best option for equipping the equipment in the basement will be a two-pipe wiring with natural circulation.

Norms 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 followed when installing equipment in the cottage. Such documentation includes:

  • SNiP "Gas distribution systems".
  • SNiP "Gas Supply" does not contain mandatory requirements, however, it will help to deal with 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 safety measures for installing a dual-circuit gas boiler in a private house

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

  • room area - 4 m2;
  • entrance door to the room - from a width of 80 centimeters;
  • lighting, natural as well as artificial light; window - from 30 square meters;
  • ceiling - two and a half meters;
  • Mandatory installation of the ground loop;
  • mandatory installation of a cold water pipe;
  • the chimney must be proportionate to the power of the device;
  • walls need aligned.

Therefore, double-circuit appliances should be placed in the kitchen. Since the kitchen has a layout that meets all safety requirements, standards. Wall-mounted appliances are best suited for the kitchen, as it is easy to place in the room, the problem of connecting cold, hot water will be solved. And for the installation of a floor device, an additional room or boiler room is needed.

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

How to install a gas boiler in a private house

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

Installation and connection of a gas boiler

There are only two types: floor-standing, wall-mounted boilers. Instrument installation is slightly different.

Installation of wall technology:

  1. protect the wall in advance on which the unit will be located with refractory material;
  2. preparing the apparatus, it is necessary to clean the walls of the inlet tubes from debris and dust under high pressure of water;
  3. install a filter, shutoff valves on the water supply pipe;
  4. we mount a chimney;
  5. check traction;
  6. then you need to make the insert of the unit into the gas pipeline, it is better to provide this work to the employees of the gas service;
  7. We connect the device to power supply.

Procedure for installation of floor equipment:

  1. it is necessary to build a strong pedestal that can support the weight of the unit;
  2. level gas equipment using 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 the gas apparatus to the main line is best done by gas service workers.

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

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

  1. It is necessary to dig a rectangular groove in the ground, a width of 35-40 cm, a depth of 50 cm.
  2. Drill pits at the corners of the ditch.
  3. In the pits, score corners 60 mm wide, 3 meters long.
  4. Scalp the triangle with a strip of 4 cm, stretch the same strip from the ditch to the house.
  5. Weld a spire onto the end of the strip, attach a ten-centimeter spire to the base of the building.
  6. From the spire, ground to gas equipment.

Grounding guarantees the safety of the gas boiler.

The nuances of installing a wall gas boiler

The wall-mounted unit must be free of dents, signs of damage and repair. If the gas boiler has external flaws, then you should contact the store where it was purchased.

The chimney for a wall-mounted boiler must comply with some standards:

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

Wall boiler piping

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

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

The nuances of installing a floor gas boiler

During the installation of the apparatus, inside the chimney, three outlets must be installed, all over it. And the length of the pipe that connects the boiler and the chimney should be around 25 cm.

It is necessary to choose the correct position of the floor boiler, for the convenience of its repair in the future. Also, in each boiler line, it is necessary to install shut-off valves, valves, which will allow you to remove it without draining the coolant from the entire system.

Floor equipment strapping scheme

Floor equipment can heat a large space. Installing this equipment is more complicated and expensive, as is its strapping scheme. It is more complicated, because the outdoor equipment is being shared with the security group. And that is why it is necessary to independently mount the pump, expansion tank.

Floor boiler piping schemes are divided into two types:

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

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

When choosing a gas heating system as the 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 rules. When constructing the scheme, you need to build on the selected model of a gas boiler. The best option is a two-pipe boiler, but for its installation and installation, you need the help of employees of the gas organization that supplies gas to the house.
