Low pressure in the heating system of a private house
The reasons
Private house heating system
includes such
boiler equipment,
as a gas heating boiler (solid fuel, diesel or electric),
heating manifold
, circulation pumps, expansion tank, piping and
aluminum heating radiators,
steel, cast iron or bimetallic. Also, the system may include a water heater (boiler).
If each element of the system is correctly selected and correctly installed, there should be no problems and interruptions in work, but sometimes, for example, after a long downtime, a reduced pressure in the heating system.
This is due to the fact that there is air in the system, which gradually exits through automatic air vents or when manually de-airing the radiators. Therefore, at first
private house heating system
may require frequent recharge.
If more than a month has passed since it was launched heating system of a private house,
all the same
the pressure in the heating system drops
, the reason may be in the expansion tank, or rather, in the incorrect calculation of its volume. Then the safety valve releases the water and the pressure decreases when it cools.
If everything is normal with the expansion tank, the reason is the leakage of the system. This may be due to the fact that when the installation of heating in the house,
did not pay enough attention to commissioning, or there is a leak somewhere.
If a heating boiler
and the pump is running, but there is no circulation of the coolant in the system, it is necessary to check
radiators for home heating,
perhaps airing is taking place. Often the reason is closed taps. Next, you should clean the filters. Typically, these actions are 90% guaranteed that
private house heating system
will work.
But if all of the above actions did not help, it is best to contact the specialists who will conduct repair of the heating system
quickly and efficiently, carry out diagnostics and commissioning of heating equipment.
Gas boiler maintenance and repair
Preventive repair and maintenance of gas boilers allows you to prevent more serious malfunctions in the system. Service should be regular. As a rule, it includes such work as: cleaning burners and combustion chambers, checking the tightness of the structure, cleaning the gas outlet and gas supply channels of the boiler, checking built-in electronic devices, dirtying the chimney, the composition of the gas in the combustion chamber, etc.
Most often, there are problems with the boiler control board. Repairs may vary depending on the brand of equipment. But, as a rule, the boards have a lot in common. If a person does not understand the device of the heating system, does not have a certain level of knowledge and skills, repairing the control board of a gas boiler will be very difficult for him.
Rules when repairing the gas boiler control board:
- before proceeding with the repair, you need to carefully read the instructions for the gas boiler;
- all sensors must be connected with correct data suitable for the operation of a gas boiler. To avoid surges, you can use a special device - a voltage stabilizer for a heat boiler;
- You do not need to apply full voltage to the board immediately Otherwise, the entire boiler automation may burn out.
Repair of heating pipes
To country heating system
worked like a clock, providing a normal level of heating and hot water supply, it is necessary during the installation process to pay maximum attention to the design, installation and selection of system elements, especially pipes. Often, in order to save money, the owners install plastic pipes, since they are cheaper than copper ones, but, unfortunately, they do not justify themselves and fail much earlier. Therefore, we have to spend
pipe repair.
The weak point of plastic pipes is the connections, so in no case should they be hidden in the walls. The exception is copper heating pipes.
So, a leak has been detected - it does not matter if it is a water pipe or a heating pipe, what needs to be done:
- Disconnect it from the water supply (heating) - it's good when it was mounted country heating system,
a collector was provided, then you will not have to sacrifice comfort, especially in winter, and turn off the entire system. - If fittings are the cause of the leak, it is enough to replace them with new ones, but if the pipe bursts, it will have to be reinstalled, since repair of a plastic pipe
it is useless in heating and water supply systems - due to the high pressure, it will leak again. Alternatively, you can cut out the damaged piece and weld a new one, but since it is plastic, there is no guarantee that the joints will not start flowing over time. - Pipe repair
made of plastic most often involves their dismantling, therefore, it is better to install immediately
copper pipes for heating,
at least in this area. With the help of adapters, they can be combined with plastic, and
brazing copper pipes
is sealed and will not break even during pressure surges. In addition, they can be hidden in the wall, unlike plastic ones. - After repair of heating pipes
will be carried out, it is necessary to turn on the system, but do not immediately give a large pressure, first check the reliability of the connections, and then diagnose the system.
Repair of heating pipes in a private house
you can do it yourself if you have the skills, but it is better to contact the specialists, preferably those with whom it was mounted
suburban heating system.
They will carry out the whole range of work much faster and better, as well as check and adjust the normal operation of heating equipment.

Heating system repair stages
Without exception, all repairs, including those related to the heating system, provide for the following:
- Removal of old heating equipment and replacement of radiators. At this stage, old heating radiators are dismantled with their subsequent washing, repair and replacement (if necessary). Compared to cast iron radiators, special care for bimetallic and aluminum batteries is inappropriate.
- Flushing of pipelines, if the user does not want to update them, planning to use the old structures.
At this time, flushing of the heating system pipelines is carried out in two ways: chemical and pneumohydraulic. The first is used if scale or corrosive build-up has formed inside the pipeline. The second technique is used when it is necessary to eliminate sludge deposits from the pipeline.
Any method of flushing involves the use of a compressor that pumps water, similar to transporting a heat carrier through the nodes of the system.
When it comes to large households, each individual heating circuit is flushed. In this case, the following sequence is observed:
- The radiators of the heating system are washed.
- The heated water supply pipelines are washed.
- The pipelines of the return circuit, through which the cooled water flows, are flushed.
The simplest technique for cleaning pipelines of a heating system is flushing, during which caustic or soda ash is added to the water.Before performing this procedure, the batteries and tubing must be disconnected and removed from the brackets.
Further, the plug of one hole is implemented, followed by the supply of the prepared liquid from the other side of the radiator. As soon as the liquid fills the cavity of the structure, it is necessary to plug the second hole. After an hour and a half of waiting, the working fluid is drained and the radiator is flushed with clean water. You can use a compressor to pump it.
Also, a special liquid can be used to flush the heating system, which is used to clean car radiators. You can keep such a liquid inside the battery for no more than ten to fifteen minutes. Further, clean water is supplied for the final flushing of the radiator. It should be noted that only hot water is used with the automotive fluid.
So that the above deposits do not accumulate in the batteries, and the heating system works efficiently, you should:
- Do regular flushing.
- Use only purified water during flushing. Using a high-quality liquid will allow you to flush the radiators irregularly. It will also extend the period of operation of the heating system.
