The Ultimate₃ regular boiler provides outstanding heating performance in a 25kW model, and is best suited to homes with high hot water demands, where a hot water storage cylinder and a cold water tank are already installed.

Being both lightweight and very compact, the Ultimate₃ regular boiler can easily be installed within a kitchen cupboard if required.

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.
