Heat Recovery Ventilation

Heat recovery ventilation , also known as a heat exchanger is a ventilation system that extracts the warm moist stale air from the building and replaces it with clean filtered fresh air, without letting the heat escape.

HRV provide fresh air and improved climate control by improving air quality and protecting the fabric of the building.

As building are intentionally made more air-tight, they become less ventilated. In order to get more fresh air into the house, windows can be opened but this can cause a problem both in summer and winter due to the heat and humidity that will be lost.

Therefore it may not be a practical solution as far as the climate and energy efficiency for the indoor climate.

Heat Recovery Ventilation provides high efficiency ventilation throughout the house and are economical to run.

The system recovers up to 95% of the heat from the extracted stale air through a heat exchanger, the incoming air is filtered to reduce the incidence of pollen and dust.

This kind of systems can be very beneficial to people who suffer from allergies to dust and also those who are asthmatic as the air in the house stays fresh. Sick Building Syndrome
