Viessmann Vitodens 100-W 19kW Combi Boiler

The Vitodens 100-W 19kW is a reliable combi gas boiler, with an output of 27.3kW for central heating and 19kW for hot water, which is ideal for medium-sized homes with up to 15 radiators and a single bathroom and en-suite. For larger homes with a higher demand for hot water and central heating, the Vitodens 100-W 25kW and 32kW. 

Thanks to its high-efficiency rating of 94% and also an ErP A-rating for both heat and hot water, the 100-W combi boilers are known for their reliability and their ability to reduce your carbon footprint and energy bills. Also, thanks to its compact design, this model can be installed neatly into your standard kitchen cupboard.

Combi boilers are often preferred over a system or regular boiler as they remove the need for any additional storage tanks or cylinders, as both your central heating and a water heater is combined in one unit, saving you space in your home.
