Vokera Vision 20s System Boiler

Thanks to its efficiency rating of 89% this model of boiler can also help to reduce your energy bills if you have an older, inefficient boiler. However, many newer boilers offer efficiency ratings of up to 96%.

The Vokera Vision 20s has an output of 20kW which is powerful enough to heat a home with up to 15 radiators and a single bathroom. If you believe that your home has a higher demand for central heating and hot water, the Vision 25s is also available with an output of 25kW. 

However, it is important to note that when purchasing a new or replacement system boiler, you will need to have the room in your home for an additional hot water cylinder, which is typically located in an airing cupboard of a home. For this reason, system boilers are not recommended for homes with limited space. On the plus side, the Vokera Vision range is also available as a combi boiler if space is limited in your home.
