How a boiler works – A guide to your gas boiler |

A gas boiler functions in a similar way to oil or biomass boilers, with the central element being the burner; this is switched on and off by a heating control.You can either trigger the switch manually or by setting the thermostat to react when the temperature drops below a certain level.. A Piezo ignition, ignites for a period of one to two seconds and then after around one second the gas
