Ariston Clas One 38kW Combi Boiler

With an efficiency rating of 90% and an ErP A-rating for central heating and hot water, this combi boiler could potentially help to reduce both your carbon footprint and your energy bills, depending on the efficiency of your current heating system.

Combi boilers can be found in many UK households as they are loved for being great space savers. Combi boilers combine both the water heater and the central heating element in one nifty unit, making it compact and lightweight. This allows them to be installed neatly inside your standard kitchen cupboard.

As mentioned, the Clas One combi boiler range has three output models with outputs of 24kW, 30kW and 38kW, therefore, if your home has lesser demand for central heating and hot water, there are other options available.
