BACK BOILER Meaning and
Definition
-
A back boiler refers to a heating unit that is commonly installed in a fireplace or stove, functioning as an additional source of heat for domestic water and central heating systems. It is named so because it is positioned behind the fireplace or stove, within or connected to the chimney breast.
Typically, a back boiler consists of a reservoir or vessel that holds water, directly connected to a range, fireplace, or stove. The water in the back boiler circulates through a network of pipes, often referred to as a heat exchanger, which transfers the heat generated by the fireplace or stove to the stored water. This heat exchange process allows the water to warm up, providing both hot water for household purposes and heating for radiators or underfloor systems.
Back boilers are usually integrated into open fireplaces or stoves and offer a way to utilize the heat produced by such appliances effectively. They are known for their efficiency and can be used with various fuels, including coal, wood, and gas. However, it is necessary to note that back boilers are typically designed to be used in conjunction with a complete central heating system and are not standalone heating units.
In recent years, back boilers have become less common due to the development of more sophisticated heating systems, such as combi-boilers and condensing boilers. Nonetheless, they still serve as a practical solution for homeowners who prefer traditional fireplaces or stoves and desire an efficient and environmentally friendly way to heat their homes.
