Products - Ventilation & MVHR

Benefits of MVHR

Even as the UK struggles with some of the most polluted outdoor air in the world, indoor air quality can be even worse, as poorly ventilated homes allow humidity, carbon dioxide, mould and toxins to build up with no easy means of escape. This is compounded in winter, when windows and doors are kept firmly shut to stop cold air getting in and heat escaping. Poorly ventilated homes are strongly linked to respiratory problems, allergies and asthma. A well-designed ventilation strategy can turn your house into a healthy home.

A Mechanical Ventilation Heat Recovery (MVHR) system meets the ideal for both good quality ventilation and a warm home in winter. With an MVHR system, indoor air is extracted from rooms at rates which keep excess humidity, carbon dioxide and toxins at healthy levels. This warm extracted air is run through a heat exchanger and the heat is passed to incoming cold air from outside. At efficiency levels of up to 96 per cent, an MVHR can re-heat cold outdoor air from zero to 18 degrees Celsius. When this fresh air comes back into the home it’s at a much more comfortable temperature. MVHR systems also contain filters which remove pollen, carbon dust and other toxins from outdoor air, and can even be fitted with NOx units to deal with toxins from diesel fumes.
