With an efficiency rating of 92% and an ErP A-rating for heat, the Biasi Advance 25kW system boiler could potentially help you to lower your energy bills, depending on your current boilers efficiency rating. This system boiler has an output of 25kW, perfect for small to medium-sized homes with up to 15 radiators and the main bathroom. For homes with a higher demand for instant hot water, the Biasi Advance Plus 7 30kW and Advance 30kW system gas boiler are also available.
System boilers are ideal for homes that have a high demand for instant hot water to two bathrooms simultaneously, this is thanks to the additional hot water cylinder that is installed alongside your boiler unit, which allows you to keep unused hot water in a sealed tank until you need it.
Although system boilers are ideal for homes that have an instant demand for hot water, they do take up more space. For this reason, we don’t recommend system boilers for homes with limited room.
