What Is an Energy Recovery Ventilator?
An energy recovery ventilator is a ventilation system that exchanges the stale air from your home with fresh air from outside without wasting energy.
How Does an ERV Work?
An ERV works by transferring the thermal heat and moisture between exiting and entering air streams. During the winter months, the stale, warm air from your indoors is exhausted to the outdoors; at the same time, cool, dry, fresh air from the outdoors is drawn indoors by a fan. In the core of the ERV, the thermal heat and moisture from the outgoing air is applied to the incoming air. This action pre-treats the incoming air so that it is warm and has extra moisture before it enters your air flow. In summer, the opposite occurs: the outgoing dehumidified air pre-treats the incoming warm, moist air, removing excess moisture and cooling it before it enters your system. The pre-treating action of the ERV provides numerous benefits:
- Better energy efficiency – the pre-treating action of the ERV helps take some of the workload off your system; when your system doesn’t have to work as hard to produce the temperature you want, you use less energy.
- Better indoor air quality – with an ERV, your home has a steady, constant stream of fresh air, which can significantly improve your indoor air quality.
- Balanced moisture control – during the winter season, the air inside your home can become too dry, making the temperature feel cooler than it is; in summer, excess moisture can cling, making the temperature feel warmer. An ERV can help provide better moisture control by adding moisture to incoming air during winter and dehumidifying it in summer.
If you’ve been looking for a way to improve your energy efficiency and indoor air quality, an ERV may be just the device you need.
