What is the Difference Between an HRV and an ERV?
Having a better understanding of the inner workings of your HVAC system will enable you to take better care of it. As HRV and ERV systems are the chief cooling methods employed by HVAC systems, you’ll need to know the differences between the two.
HRVs transfer heat, while ERVs transfer heat and humidity. They reclaim energy wasted in an exhaust air stream and reduce the cost of ventilation. These products have been performance evaluated for airflow and heat or energy transfer. Bounds Heating & Air, your trusted air conditioning repair contractor, explains further:
Heat Recovery Ventilator (HRV)
HRVs are most often used in colder climates during the winter. They keep the home supplied with a steady flow of fresh outdoor air while expelling warm, stale air from the home. Its heat recovery core warms the incoming fresh, cold air before distributing it within the home. This results in a constant supply of fresh air with greater home comfort and no unpleasant drafts.
Energy Recovery Ventilator (ERV)
An HVAC repair professional can also install an ERV that coordinates with your existing unit, allowing you to enjoy fresh air without putting an extra load on your HVAC system. It works by pulling fresh air into your home while expelling indoor air from the structure. This exchange of air would usually affect indoor temperatures, but an ERV conditions the incoming air before it joins your airstream. It heats or cools the air as needed for minimal impact on the comfort of your home.
Additionally, dehumidification features ensure that incoming air doesn’t bring in excessive amounts of moisture. An ERV is usually the better option if you have air conditioning and live in a humid climate. Before installing either one, make sure to check for air quality issues in your home.
