Heat Recovery Ventilator

Life inside today’s tight homes generates both moisture and pollutants. The moisture comes from cooking, washing, showers and breathing. At excessive levels, moisture condenses on windows and can cause structural deterioration. Areas of excessive moisture are also breeding grounds for mildew, fungi, dust mites and bacteria. You know you have a problem if you find moisture collecting on your windows, or if you notice black spots on walls. These unsightly spots indicate mildew growth. Small spores and dust easily become airborne and circulate freely throughout the house, possibly causing a range of symptoms and allergic reactions.

Heat-recovery ventilators (HRV) are similar to balanced ventilation systems, except they use the heat in from the outgoing stale air to warm up the fresh air. What makes an HRV so unique is the heat-exchange core. The core transfers heat from the outgoing stream to the incoming stream. It is composed of a series of narrow alternating passages through which incoming and outgoing airstreams flow. As the streams move through, heat is transferred from the warm side of each passage to the cold, while the airstreams never mix.



Depending on the model, HRVs can recover up to 85 percent of the heat in the outgoing airstream, making these ventilators a lot easier on your budget than opening a few windows. And, an HRV contains filters that keep particulates such as pollen or dust from entering the house.

  • Recovers up to 85% of outgoing heat, saving you money
  • Enhances your comfort and helps control wintertime condensation
  • Reduces mould and mildew
  • Recovers up to 5 times more energy than it costs to operate
  • Starting January 2016, HRVs are required in new homes



Remember, your HRV wasn’t designed to last forever, but you can keep yours running smoothly for longer with proper maintenance and repairs as necessary. We carry a variety of water products to meet your needs. Contact us for details.
