Glow-worm is a boiler manufacturer with over 80 years of experience in the heating industry.
Although slightly less popular than other more common brands, Glow-worm’s products are by no means sub-standard. With a range that spans combi, regular and system configurations, Glow-worm boilers are more than capable of meeting your heating demands.
When buying a new boiler, it is essential to consider all available options at the time of purchase. To help you make an informed decision, Compare Boiler Quotes has conducted an in-depth review of Glow-worm’s products to provide you with the information you need, including:
Glow-worm is a UK-based boiler manufacturer that has been in operation since 1934. With facilities in Derbyshire, Glow-worm is one of the only brands in the market to develop its products inside the UK.
In 1992, Glow-worm claimed to have possessed around 40% of the heating industry’s market share, whilst also being the first company to popularise the condensing boiler.
In 2001, Glow-worm was acquired by then competitor Valliant, providing Glow-worm with an even larger competitive advantage in the industry.
Although Glow-worm’s popularity has dwindled in recent years, its products are still regarded as being some of the best available.
Much like its competitors, Glow-worm offer an extensive range of regular, combi and system boilers in various configurations. Many of them come with long warranty periods of up to seven years, in addition to Quiet Mark certifications due to their low noise.

Larger households with higher energy requirements may wish to choose a boiler with a slightly larger heat output. The Glow-worm Ultimate3 is a great choice for larger families with multiple bathrooms due to its more competent heating abilities – Read our full Glow-worm Ultimate3 review.
The Betacom range of boilers is better suited for smaller homes or even apartments with less occupants.
