How the Zehnder HRV/ERV System Works

Allen Gilliland of One Sky Homes describes the importance of designing and building to ensure optimal indoor air quality in a high performance home. In the video, he shows how the Zehnder balanced ventilation system provides continuous fresh air to the home.

Zehnder’s California Dealer, Hayward Lumber, describes the importance of continuous ventilation and how Zehnder’s system ensures a healthy indoor environment.

Beside being quiet, the Zehnder HRV is visually discreet. In this video, Skylar of Hammer & Hand takes a walk through the house and shows us the small supply and exhaust ports. He also explains why controlled, balanced ventilation makes sense in any house: Besides saving energy, increasing comfort, and guaranteeing good indoor air quality all year round, it’s really the only way to know where the house’s makeup air is coming from.

The whole house heat recovery ventilation system works continuously to extract moist, stale air from wet rooms (kitchens, bathrooms and utility rooms) and supply fresh, filtered air to habitable rooms (bedrooms, living rooms and dining rooms). Up to 90% of the heat in the extract air is recovered by the heat exchanger in the unit and used to heat the incoming fresh air.

Brooklyn Independent Television gives a great look at some Passive Houses in Brooklyn aiming to reduce heating and cooling by up to 90% and using Zehnder Ventilation.
