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 24kW is the most powerful boiler when it comes to boiler output. It can heat a home with up to 20 radiators and a bathroom. Meanwhile, many homes do not need this demand for central heating and hot water, in this case, the 12kW, 15kW, 18kW or the Ultra 21kW are available for those with lesser demand.
