Thanks to its efficiency rating of 91.1% and an ErP A-rating for central heating, this regular boiler could potentially help you to reduce your energy bills. Thanks to these ratings, the Promax SL Heat regular boiler has been recommended and approved by the Energy Saving Trust.
The boiler itself is one of the smallest and lightest boilers on the market, with a low-lift weight of 26kg, meaning that this boiler can be fitted inside your kitchen cupboard, out of sight, out of mind.
The Potterton Promax SL 12kW is an open vent boiler that can be used in flats and smaller homes, as long as you have a hot water storage tank or an economy 7. Usually, regular boilers are fitted with an additional cold water feed that is installed in the attic of your home, as well as a hot water storage tank, typically located in an airing cupboard. Therefore, if your home has limited space, a regular boiler may not be the best option for you.
The Promax SL Heat 12kW is the least powerful of its range, however, it is ideal for homes with up to 10 radiators and a bathroom. For larger homes where demand for hot water and central heating is higher, the Promax SL Heat 15kW and 18kW are available. For even larger homes, check out the Promax HE Store.
