The causes of pressure drop in the gas boiler

In order to heat their holiday homes or premises with a large area, people buy two-circuit gas boilers. What are the main advantages of these boilers? The advantage is that the natural gas on which the devices operate is generally available economically. In our country it is now difficult to imagine even the smallest town without a gas main. Although in the villages with this problem, but no one bans to refuel the cylinder with natural gas and heat the living quarters. Also, the advantage of dual-circuit boilers is that there is no need to heat the water in the house, plus putting the necessary temperature in room, the boiler itself will support it, which in itself saves your strength and money, as it eliminates the need to install boilers and columns. Nevertheless, like any technique, a gas boiler can break down or become unusable. Most often this is expressed in a drop in pressure. How and why the pressure in the gas boiler drops is discussed in this article.

General information

Most modern gas heating boilers with pressure drop in the system, it ceases to function, that is, it turns off. At the same time, there is a threat of failure of the heating system and equipment. In order to find out the reason why the pressure in the boiler drops, you need to know its working value. Usually this is the static, dynamic and maximum working pressure. In our case, in order for the system to function properly without malfunctions, this is the dynamic working pressure. When installing and connecting a gas dual-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 a pressure, as well as a position in which it is indicated in which cases it can exceed or be less than the permissible worker. The pressure in the pipeline of the heating system is measured in atmospheres or in abbreviated form. Typically, the minimum pressure is possible when the coolant is first pumped into the system. This is because after the system heats up, the pressure also rises to the acceptable level.

All double-circuit gas boilers have a complex design, so if one of the constituent parts of the boiler fails, a malfunction occurs. Therefore, independent repair of equipment is not recommended. If an incorrect operation of the system is detected, it is necessary to call a specialist who will perform the necessary maintenance qualitatively and without any difficulties.

Causes of the problem

If there are any malfunctions and malfunctions in the operation of the gas heating boiler, it is necessary immediately to look for the cause. In most cases, the failure occurs for a number of reasons, and without special equipment it can not be detected:

• there was a leakage of water from the system;
• simple equipment in the absence of electricity;
• heater tank malfunction;
• This boiler is not suitable for your system.

If there is a reduced pressure in the water supply system, it does not enter the tank. If the gas pressure is lowered, the device switches off, while giving a certain signal. 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 can occur due to air congestion. This is because:

• the water was originally pumped incorrectly;
• air is not deflated from the coolant;
• poorly sealed heating system;
• the valves are clogged.

The first sign of the appearance of traffic jams in the system is the occurrence of noise and vibrations. In this case, all connections can be weakened by these vibrations, which leads to leaks, and naturally to a decrease in pressure. Also, air is a poor conductor of heat, and so the pipes may not warm up to the desired temperature, because of what the equipment will work for wear and you will feel a blow to the wallet.

Troubleshooting

How can I fix the problem? First of all, do not panic and take up repairs, if you do not have enough experience and knowledge in this area. Although in some cases, however, the intervention is simply necessary.

If a leakage of water or gas is detected, the flow valves must first be closed and the site where the fault is found. Further, depending on the complexity of the system, it is necessary to replace the area where the problem is noticed, while disconnecting the outputs to the radiators and the boiler. This type of work involved people with special equipment for this.

After fixing the leakage point, the system is pumped in a new way and the pressure is checked and the devices are working. This process can take quite a long time, it depends on the size of your system as a whole.

We hope that this article has helped you to understand the question of why pressure in the gas boiler is falling.
