If your home is built with energy efficiency in mind, that means it’s tightly sealed to thwart energy-wasting air leaks. With such a tightly sealed home, however, it’s recommended that you look into installing some sort of ventilation system. The best type for South Florida’s climate is an energy recovery ventilator (ERV). Here’s a look at how ERVs work and what benefits you can expect by adding one to your Florida home.
How an energy recovery ventilator works
This type of system ventilates your home with minimal energy loss. Energy recovery ventilators introduce fresh air from the outside while simultaneously exhausting stale air out. As cool, dry outgoing air passes by hot, humid incoming air, between 70 to 80 percent of the heat and moisture is transferred to the outgoing air. This is made possible by a heat exchanger included in the system.
Benefits of an energy recovery ventilator
- Moisture control: An energy recovery ventilator helps with excess moisture, which is an issue in Florida nearly year round. Because moisture from fresh incoming air is transferred to stale outgoing air, indoor humidity stays relatively constant.
- Energy savings: Other types of ventilation systems simply exhaust stale air and supply fresh air from outside without transferring any of the humidity or heat to the outgoing air first. This can cause the air conditioner to run nonstop. Thankfully, an energy recovery ventilator provides the fresh air you need in your energy-efficient home while allowing you to save on cooling costs.
- Customizable: Depending on the weather, it may be better to keep the energy recovery ventilator off for a while, such as when conditions outside are humid but not too hot. To help keep humidity levels comfortable indoors, you can program the energy recovery ventilator to run only when the air conditioner runs.
