Energy Recovery Ventilator

With the energy efficient timber frame, we recommend installation of an energy recovery ventilation system (ERV). An energy recovery ventilation system will improve the indoor quality of the air and keep the humidity in the home at a constant. In any climate, this is beneficial to help control indoor relative humidity. In the heating season, an ERV will preserve essential moisture in the home while keeping it below excessive levels.

During cooling season it minimizes the added moisture that the incoming airflow may contain. An energy recovery ventilator continuously exhausts stale, polluted indoor air and replaces it with fresh outdoor air. Energy from the indoor air (warm air in winter, cool air in summer) is extracted and transferred to the fresh incoming air so there is little energy loss.

The energy recovery ventilator system will be installed by your local heating and air conditioning contractor and be an integral part of your heat and air conditioning system. In heating climates, remember heating the air may dry it to below a desired humidity level, in which case added humidification may be needed. The use of an energy recovery ventilation system in your timber frame home will enhance the indoor air quality and humidity levels to the most comfortable zone for you and your family.

Features
An Aprilaire Ventilation Control System allows you to manage the quality of your home’s air year-round, with little effort. An Aprilaire Ventilation Controller:

• Will not ventilate if the outdoor temperature is above 100° F
• Will not ventilate if the outdoor temperature is below 0° F
• Only ventilates if a call for heat is received by your central heating system when the outdoor temperature is between 0° F and 20°
• Will not ventilate if the outdoor air will raise indoor relative humidity above 55%
• Has cycle times ranging from every one to four hours, with ventilation times lasting from zero to sixty minutes.
