Heat Recovery Ventilation is one of the most important, and most overlooked, requirements in any modern well insulated home.

A well insulated and airtight dwelling is the only way to restrict energy loss. But this also causes problems. How do you ventilate? Relying on natural air changes through cracks, gaps or untight windows is no longer an option. Opening windows and doors or having tickle vents defeats the purpose of building an energy efficient house. With a GENVEX Heat Recovery Ventilation System you can have both - an energy efficient house with controlled constant natural fresh air ventilation with almost no heat loss.

Heat Loss

The diagram above shows the proportion of heat energy escaping through the building envelope. It shows how many litres of heating oil are consumed per m2 each year. The data for older buildings is shown in pink and those for low energy housing in red.

Benefits of a GENVEX Heat Recovery System

Moisture build up from bathing and cooking can be avoided thus eliminating mould grown.

Fresh filtered air constantly replaces the stale air inside your home so no more unpleasant odours from smoking, cooking, bathroom or pets

Helps maintain healthy humidity levels in your home making it less inviting to dust mites.

Helps to save money by reducing your heating requirements by reusing the heat that would normally be lost through uncontrolled ventilation.

What is a Heat Recovery Ventilation System?

	A ventilation appliance is usually mounted in your loft or utility area, connected via ductwork to ceiling terminals. One fan extracts stale warm air through these terminals from your wet rooms (kitchens, bathrooms etc) and takes it to the ventilation appliance to be exhausted outside.

	Meanwhile, another fan draws fresh filtered air from outside and supplies it through ceiling terminals in the habitable rooms of your home (bedrooms, dining rooms, studies, living rooms).

	During this process, a heat exchanger within the appliance transfers up to 95% of the heat from the outgoing stale air to the incoming fresh air. In warmer months, the heat recovery process can be bypassed to ensure that cooler fresh air enters the home.

GENVEX Range

Genvex produce four categories of HRV units

1) Standard Range - basic heat recovery ventilation

2) Enhanced Range - heat recovery ventilation with heat pump offering additional heat boost to the incoming fresh air.

Also available with comfort cooling option.

3) Combi Range - heat recovery ventilation and domestic hot water

4 Vanvex Range - domestic hot water provision

Genvex DO NOT produce a "One size fits All" unit. It is important that the HRV unit is correctly sized to suit your home. Too big a unit and it causes air turbulence, too small a unit and it is ineffective.

We also use Lindab Safe duct fittings and a solid spiral duct. Inferior ducting will not allow your system, or any HRV system, to operate properly.
