Continuous Running, Energy Efficient, Heat Recovery Ventilator For Flats, Bungalows, Kitchens and Bathrooms

Unlike conventional extractor fans which suck out and waste expensively produced heat, Kair^TM Trakmaster KHRVF100 Heat Recovery Ventilators recover up to 65% of exhaust heat, even when operating on boost mode. The world is becoming increasingly aware of the enormous cost of energy production, and this, plus the use of fossil fuels to generate power, is a momentous environmental issue. Extractor fans potentially waste over a million kilowatts of energy every year. This is comparable to the total output of two large power stations. Replacing conventional extractor fans with heat recovery systems could save at least half of that energy loss.

"I am very grateful that all the fungus and black on the walls in each room has completely disappeared. I feel very much healthier" - Councillor Shaw, Brent
