The idea of having fresh, dry air circulating throughout the home is a simple one. In days gone by, that was achieved simply by opening windows and doors and allowing air to pass through the house. That’s no longer a reality for many, especially those who live in terraced housing or apartments.
Even for those who live in standalone houses, the reality of opening windows and doors throughout the day is generally not possible with houses often locked and shut during work hours. Without the right – or any – ventilation system, that means a buildup of moisture and stale air.
In turn, this puts more pressure on heating devices like heat pumps that work harder and cost more to operate because they are heating moist air rather than fresh, dry air.
“It’s as a result of these issues that we are seeing people turning more and more towards whole-home ventilation and energy recovery systems,” HomeTech’s Manny Boyack says. “Our energy recovery system is a whole-home ventilation system that is known as a balanced system because it equally extracts moist, stale air while inputting fresh, dry air into the home.”
The system reduces the home’s energy load because it removes moisture in the air, allowing heating appliances to work less to maintain the desired temperature.
“One of the key benefits of this system, aside from the moisture control, is the system’s ability to temper the incoming air with that which is being extracted,” Manny says. “When the air passes out through a heat exchange unit in the roof cavity, up to 80 per cent of the heat in that air that is being expelled is recovered, and that heat is then tempering the air that is being drawn into the home.”
