Our Glow-Worm boiler range
If you're looking for a high-performance, A-rated (i.e. over 90% energy-efficient) boiler that guarantees quality, reliability and exceptional value, then a Glow-Worm boiler may be the answer. Glow-Worm have been keeping British homes nice and warm for the past 80 years, and are renowned for their compact micro boilers which offer state-of-the-art technology.
Why choose Glow-Worm boilers?
Reliability & peace of mind
Glow-worm Boiler and Fireplace Co Ltd have been offering exceptional and durable energy solutions since 1934. As a matter of fact, Glow-Worm boilers go through extensive tests and quality checks before leaving the factory in Belper, Derbyshire – ensuring that reliability comes as standard with every model. It was acquired by the Vaillant Group in 2001.
Cost effective & energy efficient
The complete Glow-Worm boiler range is A-rated and operates at more than 90% efficiency, which means that more than 90p of every £1 you spend on fuel is effectively used to generate heat. In turn, G-rated boilers waste around 30p of every £1 you spend. What’s more, all Glow-Worm boilers are condensing boilers, which means that they recover heat from the exhaust gases that escape in the flue allowing you to cut down on carbon emissions and save money at the same time.
Traditionally associated with some of the most successful 20th century heating products in the UK (e.g. the Micron model), Glow-Worm continue to push the boundaries of what is possible with regards to functionality, quality and boiler design. As a result, the company still produce very compact domestic boilers which are small enough to fit in a kitchen cupboard and a good choice if you’re struggling for space.
Glow-Worm combi boilers
Combi boilers are an all-in-one solution that serve as both a central heating boiler and hot water cylinder. Their space-saving quality and increased efficiency make them a popular choice among smaller and larger households alike. In fact, did you know that over 50% of all new domestic gas boilers installed in the UK are combi boilers?

Glow-Worm conventional boilers
Conventional boilers require both a hot water storage cylinder and a water tank (or cistern) and can provide large volumes of hot water to multiple bathrooms. They’re also known as heat only, traditional, open vent and regular boilers.

Glow-Worm system boilers
System boilers work on the principle of stored hot water – much like conventional boilers. However, system boilers differ from conventional boilers in that the individual components are built directly into a system boiler, which makes the installation a lot quicker and less expensivce. In addition, system boilers do not necessarily need a water storage tank, which makes them a great choice for homes where space comes at a premium.
