Thanks to its high-efficiency rating of 89.2% and an ErP A-rating for central heating, this regular gas boiler could potentially help you to reduce your energy bills.
Regular gas boilers are not recommended for homes with limited space, this is because they need to be installed with additional hot water and cold water storage tank, which are typically located in the attic and the airing cupboard of your home. However, if space is not limited in your home, then a regular boiler could be ideal.
The Potterton Ultra Regular gas boiler range has 5 boilers with different output ratings. Included in these are the 12kW, 15kW, 18kW, 21kW, and 24kW. Although the 15kW is one of the lesser powerful gas boilers in the range, it can heat a home with up to 10 radiators and a bathroom. However, if you are looking for a boiler that meets a higher demand for central heating and hot water, the higher kW output models may be better suited to your home.
