The two-storey extension to our home was built to Passive House standards, well insulated, and airtight. The STIEBEL ELTRON decentralised heat recovery ventilation unit was installed in pairs with ducting through the walls. Four were installed in our living areas, and two in the bedroom. We find the VLR 70S a high-quality product and are happy to share our experience.
