Extreme energy efficiency

Our revolutionary bithermic heat exchanger is in every Intergas boiler and is the component that guarantees extreme energy efficiency. Thanks to its intelligent design, there’s no need for a diverter valve (in combis), valve motor, auto air vent or secondary hot water plate heat exchanger, so all the parts that tend to stick, leak or let you down aren’t there. Made from aluminium, with two separate copper circuits, its large surface area and increased waterways ensure optimal heat transfer and minimal heat loss.

All our heat exchangers come with a 10-year warranty.
