There’s a dilemma for modern homes when it comes to maintaining a balance of fresh air and comfortable indoor temperatures: when doors and windows open to allow fresh air in, the outdoor temperatures come with it, making it hard for an AC or heater to maintain pleasant conditions without massive energy waste. During hot summers and cold winters in Iowa, this presents a serious problem. How can you stop a home from becoming stuffy and dust-filled without letting in too much outdoor air?
There are solutions: heat and energy recovery ventilators (HRVs and ERVs). Baxter Comfort Solutions has technicians who can install these appliances into your ventilation system so that fresh air enters your home either pre-cooled or pre-heated. Contact us in Baxter, IA or elsewhere in the “golden circle” between Ames, Des Moines, Newton, and Marshalltown to learn more about the benefits of an HRV and ERV system.
The two devices operate in a similar fashion. They are integrated into the HVAC system to draw fresh outside air into the ducts. The fresh air moves through the HRV/ERV where it passes through a counter–current of stale air pulled from inside the house. Heat then moves from one current to the other. This is called counter–flow heat exchange, and it works no matter the season.
In winter, the cold outside air heats up from the warm inside air. In summer, the warm outside air cools down as it loses its heat to the cooler indoor air. Either way, the fresh air moves through the rest of the HVAC system already pre–conditioned to match the current indoor comfort needs.
What energy and heat recovery ventilators essentially do is "recover" the energy used to heat or cool the interior of a home and then apply it to the air entering the home. The average house will recover around 85% of the energy it would have otherwise lost to the outside air—and this results in two major benefits:
In addition, an energy recovery ventilator helps with balancing humidity, since it transfers moisture between the air currents. (Whether an ERV or HRV is the better choice for your home is something you can leave to the installers.)
