Commercial Heating Faults We Repair

Common commercial heating problems we diagnose and fix.

Complete Heating Failure

No heating across the entire commercial premises. Usually caused by a failed commercial boiler, a faulty pump, a control system fault or a gas supply issue. We prioritise complete heating failures.

Intermittent Heating

The heating works sometimes but not reliably. Offices warm up then go cold. Can be caused by a faulty thermostat, a failing pump, a control timer issue or an undersized system struggling in cold weather.

Uneven Heating

Some areas of the building are warm while others are cold. Can be caused by zone valve failures, balancing issues, blocked radiators or a faulty pump not circulating water to the furthest parts of the system.

Commercial Boiler Faults

Commercial boiler lockouts, ignition failures, overheating, pressure problems or flue issues. Commercial boilers have specific fault codes. We carry diagnostic equipment for all major commercial boiler brands.

Warm Air Heater Failure

Warm air heating units commonly found in warehouses, factories and retail units that have stopped producing heat. We repair gas fired and electric warm air heaters.
