Energy combi boilers

Our Energy combi boiler is built right here in the UK at Glow-worm’s award winning factory in Belper. It uses an aluminium heat exchanger which is designed to last longer and reduce your energy bills. The heat exchanger is also super quiet – you’ll barely even hear your boiler when it’s on!

The compact size and rear flue option gives it great flexibility to install it in more spaces, including kitchen cupboards.

The Energy combi boiler also has a highly efficient, modulating, Grundfos pump which lowers your running costs as it deftly adapts to the actual heating and hot water demand in your home.
