What is one of the key features of using an HRV system?

The use of a Heat Recovery Ventilation (HRV) system is primarily designed to retain energy by transferring heat between incoming and outgoing air streams. This process is essential in maintaining indoor air quality while minimizing energy loss, especially in climates where heating or cooling is necessary most of the year.

An HRV system allows for the ventilation of fresh outdoor air into a building while expelling stale indoor air. As the stale air is expelled, it passes through a heat exchanger where it transfers its heat to the incoming cold air. This means that in the winter, the heat from the outgoing warm air pre-warms the incoming cold air, reducing the energy demand for heating, and thus retaining valuable energy that would otherwise be lost.

This feature is particularly important for maintaining energy efficiency in modern homes that are often well-insulated. By efficiently recovering heat, the HRV contributes to lower energy bills and a more sustainable living environment.
