High Efficiency Combi Boilers

Glow-worm’s combi boilers are the ideal solution for all your hot water and central heating needs.
We’ve all been there: you turn on the shower, leave it running for a while and step in… only to be shocked by a torrent of cold water. Whilst this may be something every household has gone through before, it needn’t happen to you ever again.
Glow-worm produces a wide range of heating and hot water products, including first-class, high-efficiency combi boilers.
