Product Overview

The LWZ 370 Plus is the largest of the centralised ventilation systems offered by STIEBEL ELTRON. Designed to deliver air flow rates of 100-400m3/h the great design can recover up to 90% of the indoor heat.

Product Details

The LWZ 370 Plus removes stale air from inside and replaces this with fresh air from outside through its multiple fans. The two air flows are routed through a unique cross current exchanger which effectively recovers up to 90% of the heat. The energy saving design can help reduce heating costs but also provides a healthy indoor air quality by managing humidity as well as reducing pollutants indoors. The ventilation unit has multiple fan settings to create ideal comfort and the settings can be adjusted by a qualified installer to suit your home perfectly.
