The improved design of today’s homes has increased the energy efficiency of a house, dramatically reducing energy costs but creating an environmental problem by trapping pollutants and humidity which could be a threat to your families’ health and comfort.
A better insulated house combined with energy efficient doors and window systems creates a shell, trapping humidity, cooking odours, dust, and cigarette smoke, chemical off gassing of carpeting, furniture, building materials and plastics. This stale air could cause or aggravate numerous health conditions including asthma.
Humidity caused by cooking, laundry, showers and occupants is trapped within the house causing the warm humid air to condense on cold surfaces like windows and walls. The moisture stains paint, corrodes plaster encouraging mould growth and may cause structural damage.
Heat Recovery Ventilation (HRV) units can eliminate these problems. The compact electrically powered HRV moves stale, contaminated, warm air from inside the house to the outdoors. At the same time it draws fresh, oxygen laden air from outside and distributes it throughout the house. As the two air streams pass through the HRV they do not mix. They pass on either side of an aluminum heat exchange core which transfers heat from the outgoing air to the incoming air. The efficiency of the HRV is so great that virtually none of the warmth collected from your home is lost to the outside.
