Boiler (water heating)
The term Boiler may refer to an appliance for heating water. Applications include water heating and central heating. Using combustion, the heating provided by the burner, and thermal absorption surfaces, boilers supply the heat required in industries, buildings, and pools.
The boiler heats water to a temperature controlled by a thermostat. The water then flows (either by natural circulation or by a pump) to radiators in the rooms which are to be heated. Water also flows through a coil in the hot water tank to heat a separate mass of water for bathing, etc.
A back boiler is a device which is fitted to a residential heating stove or open fireplace to enable it to provide both room heat and domestic hot water or central heating.
