Combi Boilers by Glow-worm

High-Efficiency Combi Boilers for Every Home

Combi boilers are one of the most popular types of boilers on the market because they are incredibly compact, deliver high performance heating and hot water almost instantly, and are incredibly energy efficient.

For smaller homes and apartments with up to two bedrooms and one bathroom, our super-compact 25kW boilers like our Easicom range will help you maximise your available space whilst keeping you toasty warm. Larger homes with up to four bedrooms and two bathrooms will find that our 30kW combi boilers, including our most popular Energy Combi Boiler, are the perfect match for your needs. Homes with five plus bedrooms, or an increased demand for hot water, 35kW boilers such as our Energy 35 Combi won’t break a sweat - even if you do!

When you choose a Glow-worm combi boiler, you’re choosing the best for your home, and your family. We are a manufacturer of high-efficiency combi and condensing boilers. In fact, we developed the technology for the very first mass-produced condensing combi boiler in the 1990s. So if you’re looking for a combination boiler, you’re in safe hands.
