Zehnder ventilation
Zehnder is known for balanced ventilation, that is system D. Both supply and extraction are mechanical, and a heat exchanger recovers heat from the outgoing air to pre-warm the incoming fresh air. You keep healthy indoor air with limited heat loss.
When does a Zehnder system fit?
Balanced ventilation with heat recovery is mainly attractive for new build and deep renovation, where full ducts are possible. Comfort is high: continuous filtered fresh air and little heat loss. Ventilatiesysteem.info is independent and does not sell or install Zehnder products.
