COMPARE AND CHOOSE WISELY
Combi Boilers
Combi (combination) boilers are ideal for small to medium-sized homes. They provide hot water and heating from a single compact unit, without the need for a separate water tank. Combi boilers heat water on demand, making them energy-efficient and space-saving. However, they may not be suitable for homes with multiple bathrooms in simultaneous use.
System boilers are designed for homes with higher hot water demand. They work alongside a separate hot water cylinder but do not require a cold water tank in the loft. This setup ensures a steady supply of hot water to multiple taps at once. System boilers are a popular choice for larger households or properties with multiple bathrooms.
COMPARE AND CHOOSE WISELY
System Boilers
Electric boilers are an efficient choice for homes without a gas supply. Quiet, compact, and easy to install, they are ideal for small properties, apartments, or flats. They don’t produce carbon emissions at the point of use and require less maintenance. However, electricity is generally more expensive than gas, so running costs may be higher.
COMPARE AND CHOOSE WISELY
Electric Boilers
Also known as regular or heat-only boilers, conventional systems are perfect for homes with traditional heating setups. They use both a hot water cylinder and a cold water storage tank—typically located in the loft. While they take up more space, they provide a reliable flow of hot water and are compatible with older radiator systems.
