Preferred™ Upflow Heat Recovery Ventilator HRVCRSVB

Designed for smaller homes in a colder winter climate with moderate or low summer humidity, this HRV is like having a “one-way” window that lets fresh air in without letting your energy dollars out. Its special crossflow core transfers indoor heat energy to the incoming air before sending the stale air out. It’s a much better way to enjoy fresh air and cozy comfort inside when it’s cold and dreary outside.
