Understanding Energy Recovery Ventilation: Types and Benefits
Written by Ray.Victorell

What is Energy Recovery Ventilation?

Energy Recovery Ventilation (ERV) is a mechanical system installed in homes to improve indoor air quality and energy efficiency. The system works by exchanging stale indoor air with fresh outdoor air and recovering the energy from the exchanged air. The ERV system is composed of two ducts that run parallel to each other. One duct brings fresh outdoor air into the home while the other duct exhausts stale indoor air. The ERV unit recovers the heat and moisture from the outgoing air and uses it to pre-condition the incoming air, thus reducing the load on heating and cooling systems.

The benefits of having an ERV system in your home are numerous. Firstly, an ERV system improves indoor air quality by constantly introducing fresh outdoor air into your home, which is especially important in homes that are tightly sealed to reduce energy loss. Secondly, an ERV system reduces the energy consumption of your home by recovering up to 80% of the energy from the exchanged air. This means that your heating and cooling systems do not have to work as hard to maintain comfortable indoor temperatures, resulting in lower energy bills. Thirdly, an ERV system helps regulate humidity levels in your home, which can prevent the growth of mold and mildew and improve overall comfort.

In addition to these benefits, an ERV system also has a positive impact on the environment. By reducing the energy consumption of your home, an ERV system reduces your carbon footprint and helps mitigate climate change. Furthermore, an ERV system can help reduce outdoor air pollution by filtering outdoor air before it enters your home, which can be especially beneficial for people living in urban areas with high levels of air pollution.

Overall, an ERV system is a worthwhile investment for any homeowner looking to improve indoor air quality, reduce energy consumption and costs, and make a positive impact on the environment. With its many benefits, an ERV system is a smart choice for anyone looking to improve their home’s overall comfort and efficiency.
