Ventilation

Adequate ventilation is required in all houses for various reasons. However draught proofing of doors, etc reduces heat loss and improves comfort. Mechanical ventilation with heat recovery can help reduce heat loss - warm moist air is extracted from bathrooms and kitchens and the heat is recovered in a heat exchanger. Incoming air is also pre-heated in the heat exchanger - reducing the energy required to heat the house.
