Hot Water Heating Boiler Operation Details - 39 steps in

On a typical oil fired heating boiler in the U.S. the wall thermostat is controlling the hot water circulator, turning it on or off. It is the temperature of the water circulating through the system (sensed at the primary control on the heating boiler) that actually turns the oil burner on or off to re-heat the water.
