heat exchanger - device that transfers heat from one liquid to another without allowing them to mix. device - an instrumentality invented for a particular purpose; the device is small enough to wear on your wrist; a device intended to conserve water.
Depending on the unit selected there will be a choice of controls to operate the unit in properly. During the heating seasons, heat is transferred from the warm indoor exhaust air into the cold outdoor supply air inside the HRV heat exchanger. The ERV heat exchanger not only transfers this heat, but transfers some of the moisture in the more humid exhaust air into the less humid supply air. This heat/energy transfer means that your home heating system uses less when compared to any other form of ventilation.
