Ultimate₃ system boiler

The Ultimate₃ System boiler provides outstanding heating performance in a 25kW model, and is suitable for homes with high hot water demands (when combined with a hot water storage cylinder).

Built with an automotive grade, aluminium, heat exchanger, the Ultimate₃ is designed to offer high performance. Its Grundfos modulating pump reduces energy usage, meaning the boiler is 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 app based control (sold separately) – meaning you can control your heating and hot water from anywhere at anytime by simply using your mobile phone or tablet.

The Ultimate₃ also comes prepared with a free 5 year parts and labour guarantee when your Gas Safe registered installer registers the installation on the Glow-worm Club Energy installer loyalty programme.
