Have You Heard of Energy Recovery Ventilators?

If you are frustrated by the stale air in your home, a ventilation system may provide you with the remedy needed to not only eliminate odors but also dilute pollutants. Home sealing is great for improving the energy efficiency of your home comfort system, but it can also foster a polluted environment. This may be surprising, but the reality is that everything from air freshener to chemicals in your home’s structural materials can taint the air that you breathe. An energy recovery or heat recovery ventilator may help.

What Is a Heat Recovery Ventilator

There are different types of ventilation solutions available.

  • Exhaust-only ventilation expels contaminated air but doesn’t address the need for a supply of fresh air.
  • Supply ventilation systems use central fans to pull in fresh air.
  • Recovery ventilators pull in fresh air while expelling polluted air, providing an exchange that leads to dilution of the pollutants in the home.

The recovery aspect addresses the potential for energy loss based on the introduction of hot or cold air into the house. An HRV allows for heat transfer between the incoming and outgoing airstreams, allowing the incoming air to be preconditioned to avoid a severe impact on indoor conditions. During winter months, for example, the incoming cold air is able to absorb heat from the outgoing air, creating less disparity as the incoming air mingles with the indoor airstream. Similarly, the incoming air is cooled by outgoing conditioned air during summer months.

What Is the Difference Between an ERV and an HRV?

Energy recovery ventilators and heat recovery ventilators are almost identical. The only major difference is that an ERV includes a paper core that allows humidity to be absorbed from incoming air to limit the effect on the indoor relative humidity. An ERV is recommended for humid climates, and an HRV is often the best choice in colder climates. However, there are many cases in which either system is suitable.
