This model, the 30kW, has an output of 28kW for central heating and 30kW for hot water, making it perfect for smaller homes with up to 15 radiators and multiple bathrooms. 

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. We also advise checking out the Ariston E-Combi One 30kW Gas Boiler.

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 three output models with outputs of 24kW, 30kW and the 38kW, therefore, if your home has a lesser or higher demand for central heating and hot water, there are other options available.
