Our Range of Alpha Boilers

Boilerhut aims to provide quality gas boilers that offer longevity, efficiency and value. Alpha boilers are an affordable solution for instant hot water and home heating.

Alpha combination boilers are single-unit systems that offer home heating and hot water. They heat water on demand and circulate it through your radiators or compatible underfloor heating systems while also delivering hot water directly to your taps. With no separate hot water cylinder required, combi boilers can be a practical choice for many homes.

Alpha system boilers are great for larger homes with multiple bathrooms. They work with a hot water storage cylinder and can supply hot water to several outlets simultaneously. While they require additional storage space for the cylinder, system boilers can meet a higher hot water demand.

Alpha heat-only boilers work with a cold water storage tank alongside a hot water cylinder. They are a budget-friendly choice for homes with an existing traditional heating system and are relatively straightforward to replace and repair.

Alpha Boiler Models

Alpha manufactures a range of gas and LPG boilers to provide efficient and reliable home heating. All of our boilers are installed by expert Gas Safe registered engineers and boiler installers. Boilerhut also offers an annual service plan for all boilers installed by us.
