WHAT IS HEAT RECOVERY?
Heat recovery is a process of continuously preheating incoming cool supply air by warming it with the outgoing exhaust air. Warm air is not simply exhausted to outside. Highly efficient heat exchangers transfer a larger percentage of heat energy to incoming supply air.
A Mechanical Heat Recovery Ventilation (MHRV) system offers a solution by bringing fresh air into all habitable areas without letting the heat escape. Stale air contaminated with humidity, toxins and smells is extracted from grilles in toilets and wet rooms. Areas such as bathroom, en-suite, utility rooms and kitchens allows a constant or demand oriented air flow volume to be extracted.
Fresh air is fed directly from outside into the ventilation system initially through a filter, then the heat taken from the extracted air is used to warm the fresh filtered air in the heat exchanger and then enters the ducting system. By continuously supplying preheated air into living areas and extracting contaminated air from wet rooms, you create a whole house ventilation system. Air is allowed to circulate from supply air rooms to rooms with extract via undercuts on all internal doors and / or by the use of transfer grilles.
