Ferroli LEB Boiler

Since its foundation in 1955, Ferroli has established itself as one of the most dynamic and innovative boiler brands in Europe. Ferroli places emphasis on energy efficiency and focuses on creating environmentally friendly products such as solar-powered boilers. 

Ferroli entered the UK market in the late 80s, and has now worked its way up to one of the UK’s favourite boiler brands. The LEB is one of Ferroli’s latest eco-friendly offerings; it is an electrically powered boiler suitable for small homes and flats in need of an alternative heating solution. 

The LEB boiler is a compact, yet powerful unit, with features that make this electrical boiler one of a kind. If you are considering the LEB as your next boiler, read ahead for all the tips and information you may need. 

How Much Does The LEB Cost?

The LEB comes in four different output ratings; you can expect to pay anywhere between £500 to £1000 depending on which model your home will need. This price includes VAT. 

The installation cost is an extra cost to consider, which is not included in the boiler cost. Installation costs can often equal the boiler’s cost, so this is an important fact to consider. 


Is This Boiler Suitable for My Home?

The LEB is a brilliant heating alternative to traditional gas boilers as it runs off electricity instead of burning carbon. This makes it an excellent option for homeowners looking for a more sustainable heating solution. It is also a fantastic option for homes off the grid, without access to the mains gas network. 

The LEB comes in four different power outings; 6kW, 7.5kW, 9kW and 12 kW. These are all suitable for smaller homes with no more than 8 radiators and one bathroom. In order to decipher which kW your home will need, you will need to get your home assessed by a heating engineer. 

The LEB is a compact electric boiler that will fit in tight spaces, which makes it an excellent option for homes with limited storage space. It is suitable for both radiators and underfloor heating, and it can even be linked to a DHW tank to create a full central heating and hot water system.
