Potterton Ultra 15kW System Boiler

With an efficiency rating of 89% and an ErP A-rating for both heating and hot water, this system boiler could help you to reduce not only your carbon footprint but also help you to lower your energy bills.

It is important to note that when purchasing a new or replacement system boiler, that you will need an additional hot water storage tank, which is typically located in your airing cupboard. Although, most of the important parts of the hot water and heating system such as the pump and expansion vessel are built-in on a system boiler, making it quicker and cleaner to install.

For this reason, if space is limited in your home, it may be better to go for a combi boiler. However, if space is not an issue in your home and needs instant hot water, then the Ultra system boilers might be a perfect choice for you.

The Ultra 15kW is one of the least powerful system boilers of its range, however, it is the perfect choice if you have a smaller home with up to 10 radiators and one bathroom. If you are looking for a system boiler that can meet higher demands for central heating and hot water, the Ultra range has outputs of 18kW, 21kW and 24kW, so there is an option for everyone.
