The Intergas Xtreme combi boiler is a reliable and efficient solution for heating water and the home. With its modulating burner control, built-in weather-dependent regulator, and energy efficiency class A for both space heating and water heating, it saves energy and increases comfort in the home.
The Xtreme utilizes the proven concept of a dual aluminum two-in-one heat exchanger. The patented Intergas design with two separate copper circuits ensures optimal heat transfer and minimal heat loss. The second heat exchanger (WTW unit) is integrated into the flue gas discharge of the unit, which further cools the combustion gases. Additionally, the residual heat from the flue gases is used during space heating to preheat the domestic hot water.
To prevent damage to the additional heat exchanger in the flue gas pipe (the corrugated stainless steel hose), it is recommended to install the supplied water hammer arrestor in the hot water pipe – at least 60 cm away from the unit.
All Xtreme units are Hybrid Ready, meaning these units are suitable for expansion into a hybrid heat pump system. This can be done at the time of purchase or later on.
All Xtreme units come standard with an RF module and are fully prepared for the future. This makes it even easier to control the heating via smartphone in combination with the Intergas Gateway, the Comfort Touch thermostat, and the Comfort Touch app.
This boiler is equipped with an 80/125mm concentric flue gas discharge.
