Boiler Service in Cardiff

Because the water here is soft to slightly hard, a boiler service in Cardiff is not really about descaling — that is a hard water preoccupation. What matters on Cardiff systems is combustion, seals and the condition of the water already circulating in the radiators. A service that does not look at the system water is missing the thing most likely to shorten the boiler's life.

The city's terraced stock typically has older steel radiators and pipework that has been drained and refilled through decades of alterations, so inhibitor levels are frequently at zero. That allows magnetite sludge to form, which is what eventually damages heat exchangers and pumps. Checking and correcting inhibitor is a small part of a service visit and makes a genuine difference to how long the appliance lasts.

A proper service also covers flue integrity and combustion analysis, checking the condensate route — which on Cardiff terraces is very often an external run in a side return and a freezing risk — and leaving you with a completed Benchmark record. All our gas work is carried out by Gas Safe registered engineers, and you are entitled to see the card. If an engineer does not check the flue or record readings, you have not really had a service, whatever the invoice says.
