Glow Worm Energy 15kW Regular Boiler

With an output of 15kW, this regular gas boiler is one of the least powerful in its range, however, it is powerful enough to heat a home with up to 10 radiators and a bathroom. If you feel that you require a higher demand for heating and hot water, Glow-worm has also designed the Energy Regular 18kW, 25kW, and 30kW. Meanwhile, the 12kW is also available for those with lesser demand. 

It is important to note that when buying a new or replacement regular boiler that you will need to accommodate space in the loft for an additional cold water storage cistern, as well as a hot water cylinder, which is typically located in an airing cupboard. For this reason, we don’t recommend a regular gas boiler for homes with limited space.

On the other hand, regular gas boilers are perfect for homes that require a high demand for hot water and central heating, as the hot water is stored when needed.
