Heat Recovery Ventilation

The Problem

It has been reported that modern, well insulated homes with central heating suffer air pollution up to 10 times worse than outside.
Surveys by the (Department of Environment Transport Region) DETR and the Building Research Establishment (BRE) have found Carbon Dioxide levels in some homes to be above World Health Authority guidelines.

Current UK Building Regulations call for extractor fans in all wet areas of the property including the kitchen, bathroom, utility, en-suite, WC and trickle vents in all the windows to allow air back into the property, at a cost to the homebuilder. In France regulations already require mechanical ventilation of the whole house.

The Solution - Heat Recovery

Villavent VM400The Villavent® Heat Recovery system is designed to completely change all the air in the property at least once every two hours, continually replacing the stale damp air with fresh, warmed, clean, filtered air.

The Villavent® Heat Recovery Ventilation system recovers 60-70% of the heat normally lost through trickle vents and other breakout points in the building structure. Systems can recover 70% (crossflow) 80% (rotary wheel) or 90% (counterflow).

By installing a Villavent® Heat Recovery system you are providing filtered fresh air thus creating a healthier indoor environment alleviating allergy sufferers.

Generally the Villavent® Heat Recovery unit is of Scandinavian construction. The casing is constructed from double skinned galvanised steel sheet with thermal insulation and is very quiet in operation. The large cross flow heat exchanger is manufactured from aluminium giving both higher efficiency and longevity. The British Allergy Approved EU7 pollen bag filter and electric heater battery are fitted as standard in our VX - E/EV range of units.

Our systems comply with the current Building Regulations 2006 Part F and in Scotland standard 3.14 and therefore no noisy extractor fans or draughty trickle ventilators in windows are required. By negating the need for trickle ventilators in the windows noise pollution and heat loss is greatly reduced.
