Combi Boiler

A combi boiler is a compact unit that provides both central heating and hot water directly, heating water from the mains without needing a separate storage tank or cylinder. It’s a popular choice for households applying for boiler grants or the free boiler scheme, as part of a boiler replacement scheme under government funding initiatives.

System Boiler

A system boiler is a type of boiler that integrates most of the key components for central heating and hot water within a single unit but requires a separate hot water cylinder for storage. It's an ideal choice for larger homes or properties with multiple bathrooms, where there is a higher demand for hot water.

Regular Boiler

A regular boiler, also known as a conventional or heat-only boiler, provides central heating but requires both a separate hot water cylinder and a cold water storage tank, typically located in the loft. Cold water is fed from this storage tank to the boiler, making it well-suited for homes with traditional heating systems and higher hot water demand.
