Combi (Combination) Boiler
Combi or combination boilers, are the UK’s most popular type of boiler.
They provide heat to all your radiators plus limitless hot water on demand by heating water directly from your mains supply.
This makes them an economical solution for many households as they only heat the water you use. There is no need to store water meaning you don’t need room in your loft for a cold water tank or space for a hot water cylinder.
This often makes them great for smaller homes where space is limited.
If you are using more than one tap at the same time, the flow of hot water may be reduced, meaning they are not always suitable for bigger homes with several bathrooms.
- Compact sizes make combi boilers perfect for smaller properties.
Ideal where there is little or no loft space.
- No need for a hot water cylinder allows increased living space.
No cold water storage tank frees up a loft for conversion.
- No risk of loft pipework freezing.
Less pipework in the home makes installation typically cheaper.
Depending on your mains water pressure, the flow of hot water could be reduced when you use more than one tap at the same time.
The water can sometimes take a few seconds to heat up.
