Fanco Heat Recovery Ventilation Units are designed to provide constant fresh clean air into homes while also extracting the moist stale air out. This is all done while most importantly retaining the temperature within a home due to the heat exchanger within the unit allowing the outgoing air to pass on its heat to the fresh incoming air without the two air-streams ever mixing.
What this does for households is reduce the energy costs associated with keeping a home warm during winter as the Heat Recovery Ventilation Units create a self-contained environment where the air is kept at a constant temperature without relying so much on the household heater constantly heating the air within a household. Instead the warm air within a house is used to heat incoming fresh air as they pass each other within the heat exchanger.
