Vaillant EcoFIT Pure 630 System Boiler

Thanks to its high-efficiency rating of 94% and an ErP A-rating for heating and hot water, this model is not only reliable but can also help you to reduce your energy bills. Its compact and lightweight design means that the EcoFit Pure can be installed neatly into your standard kitchen cupboard, out of sight, out of mind.

The EcoFit Pure 630 is the most powerful in its range with an output of 30.5kW. This is ideal for homes with up to 20 radiators and 2 bathrooms. Some may feel that their home does not require this kW output for heating and hot water, if you are one of those people, Vaillant has also designed the EcoFit 612, 615, 618, and 625, which have output ratings between 12kW and 25kW.

It is important to note when considering buying a new or replacement system gas boiler, you will need to accommodate for an additional hot water tank. Although system boilers take up slightly more room than a combi boiler, they are perfect for homes that need hot water instantly. This is because, with a system boiler, the water is supplied from the mains directly into the boiler, heated up, and then stored in the hot water cylinder for when it is needed.
