Heating System Diagnosis & Repair – where to start?
1. Determine what type of heating system is installed
Hot Water or Steam Heating Systems – Boilers:
If the heat in your building is provided by warm or hot metal radiators, heating baseboards containing finned copper tubing, or wall convectors that look like a radiator but contain finned copper tubing, or if heat is provided by flexible rubber, plastic, or metal tubing run in building floors or ceilings, then the warm or hot water circulating in those devices is probably being delivered by piping circulating water heated by a heating boiler, or possibly by a steam boiler or a heat pump or geothermal system.
What’s the difference between hot water boiler and steam boiler?
A steam boiler delivers heat to the occupied space in the form of steam: the boiler boils water and sends steam through steam riser pipes and through steam radiators in the occupied space.
If your heating radiators have valves which hiss and let air escape as heat is coming on your heat is probably being delivered in pipes which circulate steam from the steam boiler up through radiators in the occupied space.
