Each type offers distinct advantages in terms of efficiency, space, and heating performance, and our team will help identify the best fit for your property. We install a wide range of boilers to suit varying heating requirements:

Combi boilers combine central heating and instant hot water in one compact unit, making them a popular choice for smaller homes or properties with limited space. They heat water on demand, which means there’s no need for a separate hot water cylinder or storage tank. This efficiency not only saves room but also reduces energy usage and running costs. Combi boilers provide hot water quickly, perfect for day-to-day convenience, and are ideal for homes with one or two bathrooms.

System boilers require a hot water cylinder but no separate cold water tank, making installation simpler and more efficient compared to traditional setups. They are suitable for homes with multiple bathrooms or higher hot water demand since they can deliver water to various outlets simultaneously without pressure loss. System boilers also integrate easily with modern heating controls. Their design allows for quicker installation times and better maintenance access, providing reliable and consistent heating for medium to large homes.

Conventional boilers, also known as regular or traditional boilers, rely on both a hot water cylinder and a separate cold water storage tank, typically located in the loft space. They are well-suited for larger properties with existing pipework and where multiple bathrooms demand hot water simultaneously. These boilers provide a steady and plentiful water supply, ideal for households with high water usage. Although bulkier and requiring more space, modern conventional boilers are designed for increased efficiency and durability.
