When You Need Central Heating Repair
Common central heating faults include radiators that are cold at the bottom (sludge build-up) or cold at the top (air lock), a pump that’s not circulating water, thermostats that don’t respond, a zone valve that’s stuck open or closed, and pressure that drops repeatedly. Cardiff’s hard water contributes to sludge and scale in older systems that haven’t been power flushed.
Our Central Heating Repair Process
We assess the system methodically starting with the boiler and working through the pump, zone valves, radiators, and controls. We test water flow and return temperatures across radiators to identify where the problem lies. Once diagnosed, we give you a clear quote and complete the repair. If sludge is found, we may recommend a power flush to restore full system performance.
Central Heating Repair Cost in Cardiff
Costs depend on the fault. Minor issues like bleeding radiators or replacing thermostatic valves are low-cost jobs. Pump replacements and zone valve work cost more. We always quote before starting.
