Overview

  • Many homes today require ventilation air due to tight construction. Fresh air needs to be introduced and air must be exhausted to balance building pressure.
  • The Exhaustflow Technologies system utilizes the building/home exhaust air being rejected to enhance HVAC equipment efficiency.
  • Heating operation typically provides the greatest efficiency gains due to the significant temperature difference between the exhaust air and ambient conditions.
  • This reduces reliance on supplemental heating sources such as gas or electric backup heat, further improving overall system efficiency.
