Glow Worm Boilers

The range of glow worm boilers available at PlumbProud

In 1934, the Glow-worm Boiler and Fireplace Co Ltd started manufacturing boilers with its factory directly powered by the River Derwent. For years, the company was best known for its technologically advanced back boilers eventually coming late to the fast-growing combi boiler market in 1988 with its Hotwater Express.

Since then, the Glow Worm brand has synonymous with innovation. In the early 90s, it manufactured the first condensing boiler which broke through into people’s consciousnesses and it created the ultra-thin and eye-catching ‘Micron’ combi model – the smallest central heating system appliance ever seen in Britain.

In 2001, the company was taken over by Vaillant but it’s never stopped thinking big…and small. Its research and development team focuses on achieving much lower energy consumption and in making their boilers as small as feasibly possible, best characterised by the stunning BetaCom C model from 2008.

Glow worm boilers and the company itself are held in high esteem by their customers. Over 5,000 people have given the company a 4.7 out of 5 on Trustpilot. These sentiments are echoed by our customers who love the robustness of their boilers and how efficient and cheap to run they are.

    I'm more than happy with the service received from PlumbProud. Right from the moment I enquired online about the cost of a new boiler, the service has been thorough. I received a call very soon after my enquiry and organised a next day visit. The representative was friendly and understood what i needed in terms of boiler size etc. He also talked me through the finance options available. Installation took a day and I was extremely impressed by the standard of work and professionalism of the two young men. They worked efficiently, politely and tidily to take out a monster of an old boiler and fit the new one in it's place. They took the boiler with them at my request leaving only the box for me to put with the recycling. The office staff are polite and friendly - working to get all the paperwork done and see to any modifications needed. Im very happy to recommend this company.
