A combi boiler provides both central heating and hot water from a single compact unit. It heats water directly from the mains when required, meaning there is no need for a separate hot water cylinder or cold-water storage tank.
Combi boilers are space-saving, energy efficient and provide hot water on demand. They are often a popular choice for homes where storage space is limited.
It depends on the number of bathrooms and the household’s hot water demand. Larger homes with multiple bathrooms may benefit from a system or regular boiler instead. Our team can advise on the most suitable option for your property.
A combi boiler heats water directly from the mains and does not require a hot water cylinder. A system boiler stores hot water in a cylinder, making it better suited to properties with higher hot water demands.
Modern A-rated combi boilers are highly efficient and can be significantly more economical to run than older heating systems. Replacing an ageing boiler may help reduce fuel consumption and heating costs.
A well-maintained combi boiler can often last between 10 and 15 years or more. Annual servicing helps keep the boiler operating safely and efficiently throughout its lifespan.
The correct boiler size depends on factors such as the size of your home, the number of radiators, bathrooms and your hot water usage. We can carry out a survey and recommend the most appropriate boiler output.
We install trusted manufacturers including Worcester Bosch, Vaillant, Glow-worm and Grant. The best choice depends on your property, budget and heating requirements.
Combi boilers can provide excellent hot water performance, but properties with several bathrooms being used simultaneously may be better suited to a system boiler with a hot water cylinder.
Yes. Annual servicing helps maintain efficiency, identify potential issues early and may be required to keep the manufacturer’s warranty valid.
