Thanks to its efficiency rating of 89.1% and ErP B-rating, this system model boiler is not only reliable but can also help to reduce your energy bills. The Vokera Vision 25s has an output of 25kW, powerful enough to heat a home with up to 20 radiators and a single bathroom. If you believe that your home has a lesser demand for central heating and hot water, the Vision 20s is also available with an output of 20kW, better suited to homes with 15 radiators.
It is important to make a note that when purchasing a new or replacement system boiler, you will need to ensure that your home has the extra space required for an hot water cylinder. These are typically installed in an airing cupboard, or a similar sized space in your home. For this reason, system boilers are not recommended for homes with limited space. However, if a Vokera Vision is the boiler model you want, it is also available as a combi boiler, better suited to smaller homes with less space.
