Thanks to its high-efficiency rating of 89.2% and an ErP A-rating for central heating, the Ultra Heat 21kW regular gas boiler is known for being a highly reliable boiler that could potentially help you to lower not only your carbon footprint but also your energy bills.
The Potterton Ultra Regular gas boilers have been designed to be compact and lightweight, meaning that they can be installed neatly into your standard kitchen cupboard. Although the boiler unit itself is small in size, it is important to remember that when purchasing a new or replacement regular boiler, that you will be to make room for an additional hot water storage tank usually fitted in an airing cupboard and a cold water tank, along with a feed, which is typically located in the attic. For this reason, if your home has limited space then it may be better to consider a combi or system boiler.
The Potterton Ultra 21kW is one of the more powerful units when it comes to boiler output, it can heat a home with up to 15 radiators and a bathroom. However, if you are looking for a boiler that meets a higher demand for central heating and hot water, the 24kW outputs may be better suited to your home. Meanwhile, many homes do not need this demand for central heating and hot water, in this case, the 12kW, 15kW or 18kW are available.
