Heat Recovery Ventilators Fantec SH704 (HRVs)
Heat Recovery Ventilators are complete whole house ventilation systems that incorporate a supply motor and an exhaust motor in one unit. The supply motor draws fresh air in from the outside and the exhaust motor pushes stale contaminated air out. The two air streams are separated by a heat/energy recovery core which tempers the air making it the most comfortable solution for a healthy indoor environment.
How do they work? An HRV is designed to bring in a continuous supply of fresh air into a home while exhausting an equal amount of contaminated air. HRVs use what is called a “sensible” heat recovery core. This special aluminum core transfers heat from the exhaust air stream to the incoming air stream. Fresh incoming air is tempered by the heat that is transferred from the outgoing air so you save on energy costs. Fantech HRVs are equipped with automatic defrost mechanisms so even if you live in the coldest climates you can use HVR all year long.
New homes and renovations are being made so tight with good sealing windows and doors. The buildings are being wrapped tight with the intent to save energy costs. This good intention will cause others problems with indoor air quality. The tighter homes can no longer breath. Stale air and excess humidity from cooking and showers will become trapped in the home which will cause sweating on windows. Cooking odors may linger for days due to the tight home. Exhaust fans can remove the humidity and odors at a cost, the air being exchanged must be replaced with air coming in any place it can to balance the pressure in the home. This replacement air is coming in cold and will increase your heating costs.
