Repair and maintenance of wall-mounted gas boilers

No matter how high-quality the boiler that heats your house is, it is still not immune from breakdowns. If we talk about the most common problems faced by users of wall-mounted gas boilers, then we can name the following:

1. There is a smell of gas in the room. The main reason is the leakage of "blue fuel" at the points where the boiler and the central gas pipeline are connected. Leakage, in turn, may occur due to a loose threaded connection or complete wear of the gaskets. You can fix the problem by replacing the gaskets or tightening the connecting elements more tightly. Leak testing of connections is usually done with a soap solution, but it is better to use an electronic leak detector.
2. The burner of the heater cannot be ignited or immediately after ignition it dies out. This problem can have many causes:
   • the traction sensor is out of order or there is no traction;
   • the ionization sensor does not enter the flame formation zone;
   • the contact of the sensor and the electronic board is broken;
   • faulty electronic board.

Having determined the specific cause of the malfunction, specialists choose a method boiler repair in Lviv. This may be repair or replacement of the thrust sensor, correction of the position of the ionization electrodes and other operations.

1. The three-way valve does not work. Most often this happens due to its fermentation. The main way to fix the breakdown is to clean or replace the valve.
2. The temperature in the heated room differs from the set one. Here the problem can be for several reasons:

• temperature curve set incorrectly;
• clogged main heat exchanger;
• blockage in the heating system, for example, in radiators;
• the outdoor temperature sensor is installed on the sunny side or near the window;
• thermal heads on radiators are faulty;
• air in the coolant.

1. There is a smell of smoke in heated rooms. The main reason is a blockage in the chimney and a malfunction of the draft tipping sensor. It is necessary to dismantle the chimney pipe and clean it of accumulated soot, replace the draft sensor.
2. The DHW line does not work well or hot water is not supplied at all. There are also several possible reasons for this:

• clogged secondary heat exchanger;
• faulty three-way valve;
• faulty boiler sensor;
• the electronic board has failed.
