Gas Fired Boiler


Gas Fired Hot Water Boiler
A hot water boiler is an appliance used to heat water for a hydronic heating system. The hot water is distributed through the home in pipes and radiate heat into the rooms with either a steel radiator (newer homes) or cast iron radiator (older homes) or baseboard convectors or "fin-tube" (newer homes). Once the radiator or baseboard fin-tube convector is heated with the hot water, the water is returned back to the boiler to be re-heated and the water circulation loop continues. In addition to radiators, the hot water boiler is also used with radiant floor heating systems.

These boilers can be fueled either with natural gas or propane (gas-fired) or they can burn fuel-oil (oil-fired). Fuel-oil boilers are higher maintenance than their gas burning counterparts and require regular attention to the blower and oil filter.
