While one of the advantages of boiler and radiator systems is their long life and low maintenance, they should still be serviced annually to ensure trouble-free operation. You can easily learn to check the safety valve and the pressure and water level gauges, but for safety reasons, heating system maintenance should be done by a qualified Service Professional.

Routine annual service should include checking the controls and gauges, and inspecting and adjusting the burner. In addition, the chimney and flues should be inspected for blockages or leaks. If it is a steam heating system, the air valves on the radiators should be checked and adjusted to regulate the heat.
