A boiler is a unit where fluid (most likely water) is heated up. Contrary to its name, the water inside does not actually boil. What the fluid does do, however, is exit the boiler in order to be used for a number of different appliances that use heating such as water heating, central heating, cooking and more.
How Does It Work?
A boiler uses a type of fuel source (most commonly water or glycol) to heat the fluid inside. It is then worked through your hydronic heating system and transferred to a number of different devices such as radiators and floor heating to warm up your house. A boiler can also be used as your home’s water heater giving you all of the hot water needed for your washing machine, kitchen and bathroom(s). This type of heat method is found in older homes and does not need any ductwork.
