This is how decentralized home ventilation works with the HeLuVent X1

The HeLuVent ventilation system consists of two ventilation units arranged in pairs. They always work in push-pull mode.

The fan delivers warm, used air outwards for 70 seconds.

The valuable thermal energy from the exhaust air is stored in two high-performance heat exchangers made of special ceramics and released to the outside as cool exhaust air.

Then the direction of rotation changes.

Fresh outside air is conveyed through the two warmed-up high-performance heat accumulators and released into the living room as heated, fresh air. As soon as the stored heat has been released to the fresh outside air, the fan's rotation changes the direction again, and a new exhaust air phase begins.

This means that up to 90% of the heat can be recovered.
