Comparison to HRV
Plusaire Ventilator Vs. Heat Recovery Ventilator
To maintain a good healthy air quality homes need different amounts of ventilation air at different times. This balance is created by the amount of furnace use; exhaust fan operation and the varying amount of people in the home at any given time. It is not possible to balance a house running at a negative pressure using a system such as an HRV. To help understand the difference between a Plusaire and HRV we have compiled this comparison.
Heat Recovery Ventilators (HRV)
- Costs about $300 per year in maintenance and hydro.
- When the HRV is operating heated house air is exhausted to the outside.
- Does not add the extra air needed for combustion.
- Does not add the extra air needed to feed the exhaust fans.
- Does not correct negative air pressure.
- Brings in a fixed amount of outside air regardless of the amount of air needed.
- Internal filters need cleaning monthly.
- Water condensates within the HRV and must be drained away.
- The fan noise is irritating to some people.
- Installed cost for a 2600 sq.ft house is around $3000.00.
- Does not use any hydro (electricity).
- Constantly senses and corrects the air requirements, silently and efficiently, Eliminates negative air pressure.
- A Plusaire is self adjusting, adding combustion air to feed the fuel burning appliances as required.
- A Plusaire is a powered system when the house furnace is operating and a passive system at all other times.
- Plusaire uses the house furnace fan to draw in outside air, the furnace to warm it, the furnace filter to clean it and the ductwork to deliver it around the house.
- Operating costs vary but are about 3% of the homes heating cost.
- A Plusaire Is maintenance free and comes with a ten-year guarantee.
- Plusaire does not exhaust any house air outside or collect or trap water.
- A Plusaire installed in a 2600 sq.ft. home costs around $1100.
