Vaillant EcoFIT Pure 612 System Boiler

Thanks to its efficiency rating of 94% and ErP A-rating for heating and hot water, depending on your current boiler’s efficiency rating, this system boiler could help you to reduce your energy bills.

System boilers are great for those who require hot water on demand. This is because a system boiler has an additional hot water cylinder that stores the heated water supplied from the mains. It is important to note that you will need to accommodate this extra cylinder when purchasing a new or replacement system boiler.

The EcoFit Pure 612 is the least powerful of its range, with an output of 12.3kW. If your home has a higher demand for heating and hot water, don’t panic, Vaillant has designed the EcoFit Pure 615, 618, 625, and 630, which have outputs between 15kW and 30kW.
