Gas boiler heat exchanger cleaning
If radiators stay lukewarm, the boiler is slow to heat, or it short-cycles — scale in the heat exchanger is a common cause. It cuts heat transfer, raises gas consumption, and can overheat the unit.
On diagnostics the technician flushes the primary and secondary exchangers, checks temperature sensors and the return filter. We agree the scope and price before cleaning starts.
