Heat Recovery Ventilation


Energy Efficient Ventilation

Villavent Heat recovery and Ventilation systems are designed to continually replace stale, damp air with fresh, warm, clean, filtered air. The installation or Heat Recovery and Ventilation systems are now being recommended by Uk Building Regulations and Villavent's systems have been designed to exceed these.

Heat Recovery

Norwegian efficiency has ensured that Villavent Heat Recovery units recover between 65% and 90% of the heat normally lost through window trickle vents and other break-out points in the building structure. Units can be sited in the roof void, above a Villavent cooker hood, at high level on a wall, or in a cupboard. Ducting is used to remove stale air from "wet" areas and to deliver filtered, fresh air into the living rooms. Villavent Heat Recovery Units are constructed from double-skinned galvanized steel sheet with thermal insulation, and are very quiet in operation.



The Villavent Revolution

Villavent recommends installing a rotary wheel heat exchange unit because it has the ability to:

  • 1: automatically switch the heat exchanger on and off, which will help to keep your property cooler in the summer months.
    2: has 80% heat recovery efficiency
    3: requires no condensate drain as is necessary with all other types of units.


High Performance Filtration

An EU7 pollen filter is fitted to most units, along with an electric pre-heater to eliminate cold draughts. The EU7 pollen bag has a Seal of Approval from the British Allergy Foundation. Where there are specific concerns about air quality, an additional filter can be supplied. The EU7 electrostatic filter removes 97% of all airborne particles down to 0.1 micron. This includes pollen, bacteria, smoke, viruses, country odours and traffic fumes. This is a sound investment, particularly for allergy suffers and families with young children. The system is controlled by a low-voltage control panel, which can be remotely located to suit the customers requirements. More than one control panel can be used, if required.

Summer Ventilation

Without doubt the aspect most people talk about when they have installed a Villavent heat recovery ventilation system is the ability to keep the house fresher in summer. Villavent's latest technology enables the summer bypass of the heat exchanger to operate automatically without the need for user intervention.
