What is the difference between Heat Recovery Ventilation and Energy Recovery Ventilation?

Both ERV (Energy Recovery Ventilation) and HRV (Heat Recovery Ventilation) systems work effectively to ventilate home and commercial environments but do so differently.

An ERV system uses a heat exchanger to not only transfer sensible heat (basic temperature difference) but also latent heat (the heat required to covert a solid state into a liquid or vapour). Because both temperature and moisture are transferred, ERVs are considered total enthalpic devices. The core material for ERVs is permeable to enable the transfer of moisture.

An HRV system can only recover sensible heat and remove moisture rather than use it in the heat recovery process. HRVs use non permeable cores so moisture cannot get through. For this reason an HRV system will require a drain outlet.

Depending on your individual requirement, a qualified installer will be able to ascertain which type of system is best for you.
