ERV/HRV

Improve energy efficiency through heat and energy recovery

Upgrade to an energy recovery ventilator (ERV) or heat recovery ventilator (HRV) and enjoy a constant flow of fresh outdoor air—without wasting energy. Enbridge Gas makes it easy to improve your indoor air quality and energy efficiency with professional guidance and access to incentives that help you save more.

How do ERVs and HRVs work?

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 air streams 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. HRVs are ideal for:
    • Reducing demand on HVAC systems and associated energy 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.

Disclaimers:
Eligible equipment is ERV/HRV with a minimum sensible effectiveness of 55 percent at 32 F (for CAN/CSA C439 performance test) or 35 F (for AHRI 1060 performance test) for spaces with no ERV/HRV or for spaces where ERV/HRV is not required by code (OBC, SB 10, SB 12) and ERV/HRV with a minimum sensible effectiveness of 65 percent at 32 F (for CAN/CSA C439 performance test) or 35 F (for AHRI 1060 performance test) for spaces where ERV/HRV is required by code. Incentive paid is based on the operating CFM of the ERV/HRV and to qualify for an incentive, the sensible effectiveness used to validate the above criteria must be at the operating CFM level. The offer is not eligible in: areas where the operating CFM sensible effectiveness level is below the minimum requirements above; systems where DCV or scheduled setbacks are used during operated hours; spaces where 100 percent of the exhaust air must be evacuated from the building in order to avoid cross contamination (100 percent fresh air is required such as described in OBC section 1.1.1.4. spaces where no recirculation is allowed by codes or standards, for instance, any limitations as per CSA Z317.2_10 Special Requirements for Heating, Ventilation and Air Conditioning (HVAC) Systems in Health Care Facilities); and areas where contaminants (gases and vapours) may be present and the ERV/HRV may bring them back into the breathing zone. In-suite installations may be eligible at a different incentive level.

Any references to energy savings is based on the assumption that the participant is reducing their natural gas consumption through participation in the Prescriptive Incentive program.
