With an output of 21kW for central heating and an efficiency rating of 94%, not only could this regular boiler help lower your energy bills, but it is also ideal for homes with moderate demand for central heating, with up to 15 radiators and a single bathroom. However, if you feel that your home has a higher demand for central heating and hot water, the Clas One System Gas Boiler range may be better suited to your home. This boiler range includes 18kW and 24kW.
Regular boilers such as this model are ideal for homes with a high demand for instant hot water. This is thanks to the additional hot and cold water tank, and the feed that is installed alongside your boiler unit. These are usually installed in the attic and airing cupboard of your home.
Although they can be a great option for larger homes, if your home has limited space, then we would recommend either a combi or system boiler.
