2-in-1 heat exchanger: NO breakdowns!

Our heat exchanger is guaranteed for 10 years but it’s never failed since its groundbreaking introduction over 18 years ago.

Innovative heat exchanger

The groundbreaking back-to-back, two-in-one heat exchanger combines high-efficiency in both domestic hot water and central heating modes, resulting in a unique energy efficient design. The double two-in-one heat exchanger is one of only 12 components in the revolutionary Intergas® high-efficiency condensing boiler range.

And, as there’s no diverter valve, no valve motor, no hot water plate heat exchanger, no air vent and no air pressure switch, just 4 moving parts, installation and servicing are highly energy efficient too.
