mechanical ventilation with heat recovery MVHR

Moist and polluted air, if allowed to remain, leads to condensation. This results is streaming windows, peeling wallpaper, damp clothing and bedding and eventually unsightly mould growth leading to permanent damage of the building fabric.

Mechanical extraction fans, with sophisticated sensing systems are often the most cost effective way of controlling levels of indoor contaminants. In order for these systems to work efficiently, a similar amount of air to that extracted must be allowed into the building. A convenient air entry point is not always available leading to reduced ventilation levels.

MVHR units solve these problems in three ways:

Firstly, the extraction of pollutants and simultaneous intake of fresh air balances the air movement.

Secondly, up to 90% of the heat energy in the extracted air that otherwise could be wasted is transferred to the incoming air thereby warming the room.

Thirdly, heat recovery ventilation will dry the excessive airborne moisture, greatly reducing the humidity of moist rooms like bathrooms or laundries.

Warmer, drier, safer more comfortable buildings with uncontrolled condensation eliminated.

The microscopic droppings of the house dust mite can cause asthma, rhinitis, bronchial and other allergic problems. Mechanical ventilation with heat recovery can reduce relative humidity to below 70% which inhibits the ideal living and breeding conditions of the house dust mite.

The long term benefit is global. Domestic housing uses a very large percentage of the UK's total energy production so the whole world will benefit from the energy savings gained from using heat recovery equipment, in turn this will reduce the potential of global warming and the greenhouse effect.

Controlled heat recovery meets the demands of today's life style, and sets the trend for the future of ventilation.
