The Vitodens 100-W 25kW System provide a modern unit at an affordable price. Built-in Wi-Fi offers smart capabilities, while the clear LCD screen control offers simple manual usability. Suitable for mid-sized homes.

The Viessmann Vitodens 100-W range is well known for its high-efficiency ratings and ErP ratings. The 25kW demonstrates this, with an efficiency rating of 94% and an ErP A-rating for heat. With these ratings, not only is the 25kW a reliable system gas boiler but can also help to reduce both your carbon footprint and your energy bills.

The 25kW is a compact and lightweight system boiler, that can be installed into your standard kitchen cupboard, neatly out of sight. It is important to consider that system boilers need an additional hot water cylinder when purchasing a new or replacement system boiler. The water for a system boiler is supplied directly from the mains, similar to a combi boiler, however, the heated water is then transferred into a hot water storage tank for when it’s needed. While this does take up more space than a combi boiler, it makes system boilers great for homes with multiple bathrooms and high demand for hot water. 

With a 25kW central heating output rating, this boiler is best suited to properties with up to 15 radiators and 1-2 bathrooms. If your property needs a more powerful system boiler then Vitodens 100-W range also includes a 32kW model. The 11kW and 19kW are available for those with lesser demand.
