Ariston Clas One 24kW Combi Boiler

This model, the 24kW, has an output of 22kW for central heating and 26kW for hot water, making it perfect for smaller homes with up to 15 radiators and a single bathroom.

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. They 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 to output models with outputs of 18kW, 30kW and 38kW, therefore, if your home has a higher demand for central heating and hot water, there are more powerful options available.
