Improve energy efficiency through heat and energy recovery

One of the most efficient ways to supply high-quality indoor air is by upgrading to energy recovery ventilators (ERV) or heat recovery ventilators (HRV). Both are able to provide fresh outdoor air while recovering the most energy possible from outgoing air. We can help you upgrade, with expert help and incentives to speed up payback.

What you need to know about ERVs and HRVs

Every building needs ventilation to bring in fresh air, recover energy from outgoing air and control moisture. To achieve this, most buildings are required to have a mechanical ventilation system to supply outdoor air indoors.

A heat recovery ventilator (HRV) is a ventilation system that uses a counter-flow heat exchanger between the inbound and exhaust airstreams of a building to provide fresh air and controlled ventilation. An ERV combines this ventilation system with the ability to transfer temperature and humidity in and out of a building. Choosing between HRV and ERV requires careful consideration of climate and other factors that affect indoor humidity levels.

  1. HRVs
    HRVs are designed to keep heat in while moving stale air out. What separates an HRV from other ventilation systems is the heat-exchange core. The core transfers heat from the exhaust stream to the incoming stream to warm the incoming air and reduce heating costs. HRVs are ideal for:
    • Reducing demand on HVAC systems and associated natural gas consumption and costs.
    • Improving ventilation which enhances indoor air quality while reducing buildup of moisture, mildew, fungi and bacteria.
  2. ERVs
    Where HRV only transfers sensible heat (change in temperature), ERV is able to transfer both sensible heat and latent heat. The incoming fresh air is tempered with an energy recovery core. Heat is then exchanged through the core and water vapour is transferred with a rotating wheel, allowing for the transfer of humidity as well. ERVs are therefore able to:
    • Capture the energy savings of the heat exchange.
    • Recover the energy associated with humidity levels in the air.
