How often should a gas boiler be serviced?
Usually once a year, ideally before the heating season. Most manufacturers require an annual service to keep the warranty.
My boiler shows an error or does not heat. What should I do?
Write down the error code and the boiler model. You can reset the boiler once as described in the manual. If that does not help, call us: +48 512 487 207.
I can smell gas. What should I do?
Do not switch anything on or off and do not use open flames. Turn off the gas valve, open the windows, leave the building and call 992 (gas emergency) or 112.
How much does it cost?
A service depends on the boiler, a repair on the fault and parts. We give the price by phone or after you send the form. A new boiler is priced separately.
Where do you work?
Mierzęcice and the area within 50 km, including Siewierz, Będzin, Czeladź, Tarnowskie Góry, Katowice Airport (Pyrzowice) and Zawiercie.
