Sample interview questions: Have you ever worked with hydronic systems that include heat recovery ventilation? If so, can you explain your experience with them?
Sample answer:
Yes, I have worked with hydronic systems that incorporate heat recovery ventilation (HRV).
In one project, I installed an HRV system into an existing hydronic heating system. The HRV unit was connected to the supply and return air ducts of the home, and to the hydronic heating system via a coil. Fresh air was brought into the home through the HRV unit, preheated by the heat exchanger, and then distributed throughout the home by the air ducts. Stale air was exhausted from the home through the HRV unit, passing through the heat exchanger and transferring its heat to the fresh air. This system allowed the home to have a constant supply of fresh air without losing heat.
In another project, I designed and installed a hydronic heating and cooling system that included an HRV unit. The HRV unit was connected to the supply and return air ducts of the home, and to the hydronic heating and cooling system via a coil. In the winter, the HRV unit preheated fresh air… Read full answer
