The article describes the types of heating of private houses: solid fuel boiler, electricity, air, etc., find out what to choose here tells about the types of heating systems and the right decision on the choice of heating schemes and installation stages.
Describes the materials used to construct the heating system.
Find out about the fuel used to obtain thermal energy.
Comfort and microclimate in housing are responsible for health, performance and aspiration to development.
In order not to depend on natural phenomena, it is necessary to equip heating in a private house .
Organized in a common heat supply system from one source to a large number of consumers.
In the boiler room heat is generated by burning fuel and the heated coolant through the pipeline network supplies heat energy to houses and apartments.
This system is suitable for a large number of consumers in close proximity to the heat source. Cities and large villages.
It is used for private housing or apartment buildings at a great distance from the boiler room.
Electric energy is used for heating, which is converted into heat by special devices, electric convectors.
The most common. The heat carrier in the heating system uses water or antifreeze, which are heated in special boilers and are fed through internal pipelines to radiators to heat the air.
It emits heat energy by the stove when burning solid fuel and heating the air, in a special large-diameter pipe system.
Through them, warm masses are supplied with the help of fans to all rooms of the house.
The simplest system in design.
Heat sources are heating elements that heat the air:
These devices heat the surfaces of objects such as furniture, floors, walls by means of an infrared heater.
Power is supplied to these devices through a cable of the appropriate cross-section. The scheme includes a safety system in case of an emergency.
Heating operation is regulated by thermostats and thermostats.
Important! Due to possible outages of the centralized power supply, it is necessary to have an alternative power supply system. Electric petrol generator with fuel supply.
Its operation is based on heating the liquid in the boiler and transferring heat by delivering it to the radiators through the pipeline system.
Its type depends on the nature of the fuel; gas, solid fuel, liquid fuel and electric boilers.
The decision of which boiler is better to choose is made based on its cost and fuel availability.
The heat carrier is supplied to the radiators and removed from them through one pipe looped to the boiler. Separated by filling method; top feed and bottom feed.
The positive side of is the economy of pipes, shut-off and connecting fittings, ease of installation.
The negative factor is only that the last radiator warms up less. This issue can be solved with a circulation pump.
But its absence will be imperceptible when heating a small room.
The heated liquid enters the radiators through one separate pipe, and is discharged through the other.
The two-pipe system is the most effective, but economical in materials. There are also two filling methods; top feed and bottom feed.
All the necessary materials are purchased, and the boiler is selected according to its capacity. The tool is linked.
Important! It is better to purchase consumables with a 5% margin. These are fasteners, pipes.
First of all, the boiler is installed in a specially equipped separate room.
The power of the equipment is calculated according to the principle 1 kW heats up 10 m 2 rooms. Pipelines with water and fuel are supplied to it.
The automation and security system is being installed.
Chimney pipes are connected.The heated liquid supply pipeline is removed, and a pipe is connected for supplying the cooled coolant to the boiler (return).
The next step is to start assembling the main heating system of a private house. Work begins with a shut-off valve.
The coolant supply pipes, in accordance with a previously drawn up plan, are installed at the beginning.
Then pipes of a smaller diameter are attached to them to inject liquid directly into and out of the radiator. Pipes are attached to the wall every 1 m / p.
Important! The diameters of the main pipes are calculated according to the load on the entire system, but not less than 40mm. Supply pipes to radiators 20 mm.
The volume or number of sections in the batteries can be found by the formula described in the equipment passport. On average, three sections heat 1m 3 rooms. Shut-off valves are installed in front of and after the radiator.
They are necessary to cut off equipment from the general system during repair work or its complete replacement. On the last section, in the upper plug, a Mayevsky valve is installed to drain the accumulated air when the system is filled with water.
Radiator mountings are only used with special devices. The batteries carry the bulk of the liquid and must be secured.
Attention! All threaded connections must be sealed with red fum tape for heating or sanitary flax.
The expansion tank is an important element of the system. It prevents overpressure of the liquid when it is heated.
There are two types:
The required volume is equal to 20% of the amount of all used fluid in the system.
The application of the circulation pump depends on the scale of the entire structure. The greater the length of the pipelines, the greater the need to use the device. Its power is calculated according to the table supplied by the manufacturer.
The pump is installed in the last section of the return pipe before the boiler and increases the speed of the liquid through the entire system.
The final stage of the heating system installation is pressure testing. It is produced by an air compressor that builds up pressure in the pipeline.
Exceeding the indicators should be 10% more and held for at least 10 minutes. The normal pressure of a liquid is 1.5 atmospheres.
Important! Pressure testing is carried out only on the internal system, the boiler and other devices are cut off for this time.
A more traditional type of heating is air heating . It is based on obtaining heat by burning solid fuel in a furnace.If you have a small room, one or two sources are sufficient.
In modern systems, special furnaces are used with steel pipes mounted in them to heat the air.
The hot air then enters the piping system, which distributes heat to all rooms. Their diameter is larger than that of water heating, radiators are not required. Warm air is supplied to the room through the grilles.
When choosing which heating is better, it is necessary to take into account the basic conditions:
Prices for materials, equipment, installation costs by specialists.
