The need

Newer houses are constructed with good insulation, however, another major method of heat loss from a building is via the ventilation system.

The solution

EnerSearch Solar offers a heat exchange system that recovers heat from the outgoing exhaust and pre-heats the intake air. It is combined with solar air collectors (constructed as the balcony balustrade) that heat the incoming fresh air.
