Ventilation systems with heat recovery are ideal for efficient homes built air tight. By installing a LWZ 170 E Plus ventilation system you can greatly reduce your heating and cooling costs. With a ventilation system installed in your home, you can prevent condensation and the growth of mould. The LWZ 170 E Plus also features a summer bypass function which can quickly provide cooling by exchanging warm indoor air with cooler outdoor air.
