Heat Recovery

'Life inside a home without proper heat recovery ventilation can be an ordeal due to both moisture and pollutants. The moisture is generated from cooking, washing, showers and breathing. If moisture condenses on windows at excessive levels, it can well lead to structural deterioration. Excessive moisture provides congenial environment for mold, mildew, fungi, dust mites and bacteria to grow. If you find moisture collecting on your windows, or if you notice black spots on walls, you can take it as a warning sign. These spots indicate mildew growth. Mold spores and dust easily become airborne and circulate freely throughout the house, possibly causing a range of symptoms and allergic reactions. In addition to excessive moisture and biological contaminants, appliances that utilize combustion have the potential for allowing gases, including carbon monoxide, and other pollutants to escape into the air. So you need a strong heat recovery ventilation get rid of this menace

In absence of natural ventilation system, the heat recovery ventilation acts as a mechanical ventilation system to fill the vacuum. It is a balanced-type ventilation system as it removes and replaces equal volumes of air from the home. No pressure imbalances occur in the house for heat recovery ventilation, on the contrary it improves energy efficiency, comfort and safety. It will eventually increase vapor transmission into the structure and insulation of the house, or cold drafts. The unparalleled feature of heat recovery ventilation is that it recovers 60 to 75% of the heat in the exhaust air and returns it to the home. This mechanism is instrumental in recovering moisture from the exhaust stream and helping to maintain indoor humidity in cold climates. You can locate this ventilation in a closet or utility room and that aspect makes it a quiet ventilation system.

A heat recovery ventilator is similar to a balanced ventilation system, but the main difference is that it uses the heat in the outgoing stale air to warm up the fresh air. A typical unit features two fans; one is used to take out household air and the other to bring in fresh air. What makes a heat recovery ventilator most sought after is the heat-exchange core. The core transfers heat from the outgoing stream to the incoming stream in the same way that the radiator in your car transfers heat from the engine's coolant to the outside air. It's 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. If you want to replace several bath and utility room fans with a single high-quality, long-lived system, then switch over to heat recovery ventilator now.
