What is a combi boiler?
A combination, or ‘combi’ boiler does two things; heats water and provides central heating for your home in one compact unit.
How does a combi boiler work?
To heat hot water a combi boiler works by taking water directly from the mains, igniting the gas burner and heat exchanger, and transfers this energy to the water to heat it up within seconds.
To heat your home, a combi boiler uses control valves to allow water to flow through your central heating system at your desired temperature. When hot water is required, the control valves will divert the hot water to your hot water tap as needed.
What are the benefits of a combi boiler?
Combi boilers are one of the most popular choices for homeowners in the UK due to their size, efficient delivery of central heating and hot water, and lower installation costs.
Their compact size means that they don’t dominate the room as some alternatives might do. Also, unlike system boilers and regular boilers, a combi boiler doesn’t need a water tank or hot water cylinder to deliver hot water around your home. Hot water cylinders take up extra space which some smaller homes may not have, which is why a combination boiler is often favoured by homeowners. With no need for a hot water cylinder, less pipework is needed to install a new or replacement combi boiler making installation typically cheaper than system or regular boilers.
Combi boilers are available in a range of sizes and outputs, making them suitable for everything from studio flats all the way up to large family homes with multiple bathrooms.
