The LWZ 170 E PLUS delivers up to 90% heat recovery and provides a pleasant ambiance in detached houses. The ventilation system even has a bypass function that uses cooler temperatures overnight to help cool the home down. The LWZ 170 E PLUS uses a cross current design to effectively recover the heat in the air indoors as it exchanges this with fresh air from outdoors. This unit is ideal for low energy buildings and passive homes.
