Kair^TM Heat Recovery Ventilators provide a continuous air change, replacing stale moisture laden air with fresh, warmed air from outside. Kair^TM units are easy to fit and provide an effective solution to stale, musty indoor air condensation and mould growth problems in any room in which they are fitted.

Energy efficiency

Unlike conventional extractor fans which suck out and waste expensively produced heat, Kair Single Room Heat Recovery Ventilators (SRHRV) recover up to 86% 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.

Health Dividend

As long ago as 1989, an article in the British Medical Journal referred to the health hazards associated with condensation and mould growth in dwellings. The Statutory Fitness Standard clearly states that dwellings with inadequate ventilation, condensation and mould growth problems are unfit for human habitation and Building Regulation Guidelines require a supply of fresh air and the removal of pollutants. Kair^TM units, by reducing humidity to optimum levels (Kair Health Line^TM), eradicate condensation, prohibit mould growth and discourage the spread of bacteria, viruses and dust mite activity. By expelling dust particles, gasses and other household pollutants, the units create a dramatic improvement in the quality of the indoor air supply.
