Full details
The Envirovent HeatSava 100 HT is an ideal ventilation solution for homeowners living in well-insulated properties struggling with damp, mould, and poor air quality. By providing up to 75% thermal efficiency, this unit recovers heat from extracted stale air to pre-warm incoming fresh air, significantly improving comfort while reducing heat loss. While it is highly effective at managing humidity levels automatically, the unit is specifically limited to wall thicknesses of up to 330mm, requiring precise measurement before installation.
