Today we carried out another boiler service in North london. We only carry out a full service, we dont take a quick anayliser reading and leave! Depending on the boiler we may need to replace combustion chamber seals, but on every service the burner is removed and cleaned. As well as the ignition electrodes and on condecing boilers the condence trap is removed and cleaned. If your paying for a service make sure you are getting your monies worth!!
