In order to heat their country houses or premises with a large area, people acquire double-circuit gas boilers. What are the main advantages of these boilers? The advantage is that the natural gas that the devices run on is publicly available economically. In our country, it is now difficult to imagine even the smallest town without a gas pipeline. Although this is a problem in the villages, no one forbids refueling the tank with natural gas and heating the living room with it. Also, the advantage of double-circuit boilers is that the need for heating the water in the house disappears, plus setting the required temperature in the room, the boiler itself will maintain it, which in itself saves your energy and money, since the need to install boilers and columns disappears. However, like any equipment, a gas boiler can break down or become unusable. Most often this is expressed in a drop in pressure. How and why pressure drops in a gas boiler we will describe in this article.
General information
In most modern gas heating boilers, when the pressure in the system drops, it ceases to function, that is, turns off. At the same time, there is a threat of failure of the heating system and equipment itself. In order to find out the reason why the pressure in the boiler drops, it is necessary to know its working value. Usually it is static, dynamic and maximum working pressure. In our case, in order for the system to function normally without malfunctions, this is the dynamic working pressure. When installing and connecting a gas double-circuit boiler to the system, it is necessary to study the instructions and instructions for its proper operation. For each device and the system assigned to it, there is its own pressure, as well as the position in which it is indicated in which cases it can exceed or be less than the permissible working one. The pressure in the heating system pipe is measured in atmospheres or abbreviated ATM. Typically, the minimum pressure is possible during the initial injection of the coolant into the system. This is due to the fact that after the system heats up, the pressure also rises to an acceptable level.
All double-circuit gas boilers have a complex structure, so when one of its components fails, a malfunction occurs. Therefore, self-repair of equipment is not recommended. If a malfunction of the system is detected, it is necessary to call a specialist who will perform the necessary maintenance with high quality and without difficulty.

Causes of the problem
If you find malfunctions and malfunctions in the operation of a gas heating boiler, you must immediately search for the cause. In most cases, a breakdown occurs for a number of reasons, and without special equipment it cannot be detected:
- There was a water leak from the system;
- downtime in the absence of electricity;
- malfunction of the heater tank;
- This boiler is not suitable for your system.
If there is a reduced pressure in the water supply system, then it does not enter the tank. If the gas pressure is reduced, then the device turns off, while it gives a certain signal. In order to avoid such problems with the equipment, it is necessary to carry out diagnostics and maintenance as often as possible in order to prevent the cause of the malfunction. Also, reduced pressure may occur due to air congestion. This is because:
- water was initially pumped incorrectly;
- air is not pumped out from the heat carrier;
- the heating system is poorly sealed;
- valve clogged.
The first sign of traffic jams in the system is the occurrence of noise and vibration. In this case, all connections can be weakened by these vibrations, which leads to leaks, and naturally lower pressure. Also, air is a poor conductor of heat, and therefore the pipes may not warm up to the desired temperature, because of which the equipment will work for wear and you will feel a blow to your wallet.
Troubleshooting
How to fix the problem? First of all, do not panic and take up repairs if you do not have sufficient experience and knowledge in this area. Although in some cases, nevertheless, intervention is simply necessary.
If water or gas leaks are found, first you need to shut off the supply valves and take up the place where the malfunction is detected. Further, depending on the complexity of the system, it is necessary to replace the area where the problem is noticed, while disabling the outputs to the radiators and the boiler. This type of work is done by people with special equipment for this.
After fixing the leak, the system is uploaded in a new way and the pressure and the health of the devices are checked. This process can take quite a long time, it depends on the size of your system as a whole.
We hope that this article helped you understand the question of why the pressure in a gas boiler drops.
