An Energy Recovery Ventilator (ERV) is a heat exchanger device that works with two airstreams. Using two fans, one will pull outside air into a building while another pulls stale, potentially polluted air out of that indoor environment. As the airstreams move past each other (BPE ERVs have next to no crossover between the streams), the energy from the departing heat and moisture is used to heat or cool the incoming air. Hence, the term, ‘Energy Recovery’. The use of this recovered energy via a high-efficiency ERV contributes to lower energy bills.
If the heat exchanger only recovers heat, but not moisture, it is an HRV (Heat Recovery Ventilator), not an ERV. If an HRV is needed in the event that a building is overly humid during winter, BPE ERVs can be modified to be HRVs upon request.
For most building or home purposes, a BPE energy recovery system can save 70% to 95% thermal energy when heating and cooling! The payback on such a system is typically eight months to a few years. Meanwhile, you’ll enjoy healthy indoor air quality immediately!
If only heat recovery is needed (and not moisture control) an HRV is needed. BPE ERVs only discharge moisture to the outside and can be fully sealed to act as an HRV on request. BPE makes ERVs and HRVs that can be expected to have a service life of over 20 years with reasonable maintenance.
