Energy Recovery Ventilation Systems (ERV's)

Energy recovery ventilation systems help ventilate and improve the indoor quality of a home while minimizing energy loss. During the winter, they transfer the heat from outgoing warm inside air to incoming fresh cold air. The reverse occurs in the summer as warm fresh air from the outside transfers its heat and is cooled by the cool inside air being exhausted. These systems can recover about 70% to 80% of the energy in the exiting air, delivering that energy to the incoming air. The greatest benefit of ERVs is health and comfort due to improved air quality.

Two types of systems are heat recovery ventilators (HRV) and energy-recovery ventilators (ERV). Each contains a heat exchanger, controls, and fans to push air. The main difference between the two is that the heat exchanger in an ERV transfers some moisture along with heat, while an HRV system transfers only heat. In humid climates, an ERV helps keep humidity constant during winter months as inside air transfers moisture to drier incoming air and in the summer by transferring moisture from incoming humid air to outgoing drier air. In addition, HEPA air filters can be integrated with HRV systems, which filter pollutants and odors and increase the air quality of the home.

Improved Air Quality in Platinum LEED Home

A Venmar Energy Recovery Ventilator (ERV) will be installed in our home to improve comfort and air quality. The ERV will be able to run in conjunction with a water-to-air geothermal heat pump, or on its own ECM motor. Below is a product description of the unit to be installed. Please contact us regarding information on installation and cost of an ERV for your home.

Highly reliable HEPA 4100 ERV air exchangers improve indoor air quality while providing year-round ventilation. Along with exchanging polluted indoor air for a continuous supply of fresh outdoor air, these ERV's help retain heat in cold climates and reduce the load on cooling systems in warm climates.

 

  • The healthy solution for optimal indoor air quality
  • The Venmar HEPA 4100 is the ultimate system for optimal indoor air quality.
  • This model features the remarkable HEPA filter with antimicrobian protech, which can help reduce symptoms of respiratory ailments and allergies.
  • Its unique energy recovery core extracts outdoor humidity during the air-conditioning season and transfers it, in part, to the contaminated air leaving your home, thereby preventing the humidity outside from getting inside.
  • The process is reversed during cool seasons to replace moisture loss due to home heating.
