Which Vaillant Boiler is Right For Me?

Vaillant's boiler range includes models for homes of all sizes; whether you need a combi, system or heat-only, you can find it here. 

• Vaillant Combi Boilers: Short for combination boilers, these remove the need for an expansion tank and hot water cylinder, saving you as much space as possible. These are the perfect solution for small homes, fitting into nearly all cupboards with ease. If you're in a small house, the Vaillant ecoFIT pure is a great choice fitting into any kitchen cupboard. If you have a larger household with up to 3 bedrooms, the Vaillant ecoTEC pro 28 will be better suited for you.

• Vaillant System Boilers: Also known as sealed boilers, these keep a large amount of hot water stored away so you have a constant supply around the clock. The Vaillant 630 system boiler is the perfect choice for large-family homes with multiple hot water taps running at the same time.

Vaillant Heat Only Boilers: Also known as open-vent, regular, or conventional boilers, these are often installed in airing cupboards and connected to a cold water tank in the loft. These provide a lot of hot water at the same time making them ideal for larger homes with multiple bathrooms, or medium-sized homes with low water pressure. 

Please note that we update our stock throughout the year. If you cannot find the boiler you're looking for, please don't hesitate to get in touch with us via or 02895434399 to find more information on availability.
