Vaillant completes its high-efficiency condensing-boiler range

The launch by Vaillant of the high-capacity 35 kW ecoMax 635 boiler completes the company’s range of high-efficiency condensing boilers. Its output is sufficient for large domestic properties and means that Vaillant now has a high-efficiency boiler for every type of dwelling. It has a SEDBUK A rating. As with other boilers in the ecoMAX range, this new model has a fully modulating, low-NOx burner that can be regulated down to 10.5 kW. A fully controllable pump adds to efficiency. The circular stainless-steel heat exchanger captures the maximum amount of heat from the combustion process. The push-fit condensing flue system is available in a standard 100 mm-diameter for lengths up to 10 m or 125 mm for lengths up to 20 m. Up to 21 m can be achieved with the horizontal 125 mm concentric flue, so that it is now possible to install a condensing boiler in almost any location. This boiler has a built-in 10-litre expansion vessel, automatic system bypass and 2-stage frost protection.
