One of our newest additions to the range, the Xtreme, is packed with user-friendly and energy-saving features. There are easy-to-read-and-use icons on the new illuminated touchscreen display panel, an expansion vessel is incorporated within the boiler, there’s a combined PRV and condensate connection, an integral filling loop and dual OpenTherm inputs. The Xtreme also has a passive built-in flue gas heat recovery (PFGHR) unit which raises energy efficiency to a whole new level. PFGHR reclaims more heat from waste gases than a conventional condensing boiler can achieve, which means even less energy is needed to produce hot water for the home which reduces, still further, both energy bills and emissions. The Xtreme comes with a free 10-year parts and labour warranty.

If you fit an Intergas System Filter when you install any of our boilers, we’ll add two more years to the warranty!
