The Intergas Xtreme Combi boiler combines performance, intuitive operation, contemporary design, and extremely high efficiency in hot water production.
The Intergas Xtreme uses the proven concept of the 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 heating water and cold domestic water flow directly through the heat exchanger, so the exhaust gases are cooled to the maximum, and the condensate heat is utilized efficiently.
In addition to this proven heat exchanger, the Intergas Xtreme uses a second heat exchanger (heat recovery unit). This second heat exchanger is integrated into the flue gas outlet of the unit, further cooling the combustion gases. Furthermore, the residual heat from the exhaust gases during central heating use is utilized to preheat the domestic water. As a result, less energy is needed to bring the water to temperature, which ensures an extremely high efficiency.
All Xtreme units are Hybrid Ready, meaning they are suitable for expansion into a hybrid heat pump system. This can be implemented immediately upon purchase or at a later stage, making it a forward-looking investment for a sustainable future.
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 when combined with the Intergas Gateway, the Comfort Touch thermostat, and the Comfort Touch app.
