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 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 also comes prepared with a 5 year out the box guarantee. This can be increased to a 10 year guarantee when your Gas Safe registered installer registers the installation WITH a Glow-worm Power Filter on the myREWARDS loyalty programme.
