Repair and Maintenance of Wall-Mounted Gas Boilers

No matter how high-quality the boiler that heats your home is, it is still not insured against breakdowns. If we talk about the most common problems faced by users of wall-mounted gas boilers, the following can be named:

1. The room has a gas smell. The main reason is a leak of “blue fuel” at the connection points between the boiler and the main gas pipeline. A leak, in turn, can occur due to a weak threaded connection or complete wear of the gaskets. The malfunction can be fixed by replacing the gaskets or tightening the connection elements more securely. Usually, the tightness of the connections is checked with a soap solution, but it is better to use an electronic leak detector.
2. The boiler’s burner cannot be ignited or goes out immediately after ignition. This problem can have many causes:
   • the draft sensor is faulty or there is no draft;
   • the ionization sensor does not enter the flame formation zone;
   • the contact between the sensor and the electronic board is broken;
   • the electronic board is faulty.

After identifying the specific cause of the malfunction, specialists choose the boiler repair in Lviv. This may involve repairing or replacing the draft sensor, correcting the position of the ionization electrodes, and other operations.

1. The three-way valve does not work. This often occurs due to its corrosion. The main way to fix this is cleaning or replacing the valve.
2. The temperature in the heating room differs from the set value. The problem here may lie in several reasons:

• incorrectly set temperature curve;
• clogged main heat exchanger;
• clogging in the heating system, for example, in radiators;
• external temperature sensor installed on the sunny side or near a window;
• faulty thermostats on radiators;
• air in the heat carrier.

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

• secondary heat exchanger is clogged;
• faulty three-way valve;
• faulty boiler sensor;
• the electronic board is out of order.
