Conventional Hot Water Boilers

Hot water boilers (HWB) are pressurised vessels that burn combustible fuel or use electricity to heat water. 

A gas or oil fired burner that is attached to your hot water boiler generates heat that is transferred to the water by a heat exchanger.  The hot water is circulated through pipes throughout your building into radiators or other components to disperse the heat.
