Ultimate₃ Combi Boilers

Built with an automotive, grade aluminium heat exchanger, the Ultimate₃ is designed to offer high performance. The Grundfos modulating pump also helps to reduce energy use meaning the boiler is ErP A rated when it comes to efficiency.

The boiler features a modern, bright, LCD display with an easy-to-use interface, and is also compatible with Glow-worm’s popular MiGo Link app based control (sold separately). This means you can control your heating and hot water from anywhere at anytime by simply using your mobile phone or tablet.

The Ultimate₃ comes with a 5 year guarantee as standard with the option to extend up to 10 years* when registered by a Glow-worm myREWARDS installer. Glow-worm's installer reward scheme is open to installers who are Gas Safe registered or MCS certified. The program offers Silver, Gold, and Platinum tiers, with increasing perks varying by tier. Contact your local installer to see which benefits will be available to you.

“Our boiler installer recommended this boiler. He fitted and commissioned it in the day and it has worked perfectly since then, keeping our radiators lovely and warm also plenty of hot water. We have had a Glow-worm boiler previously which served us well for over 20 years and with a 10 year guarantee we hope this boiler should see us well into the future” ~ Trusted Customer
