How it Works

An energy recovery ventilator (ERV) works much like our lungs, drawing in fresh, healthier air from outside and effectively conditioning and filtering the air before it's circulated throughout your house.

The ERV system draws out unhealthy, stale air to the outside, while transferring the temperature of the exiting air to the fresh incoming air, minimizing temperature loss. This results in a fresh and healthy indoor environment.

ERV systems utilize a core mechanism that enables the exchange of heat and energy between outgoing and incoming air streams. This core is typically made of a heat exchanger material.

A heat recovery wheel, also known as a Rotary Heat Exchanger, is a popular component in ERV systems. It consists of a rotating wheel with a honeycomb-like structure that alternately passes through the incoming and outgoing air streams.

As the wheel rotates, heat is transferred from the outgoing air to the wheel and then to the incoming air, resulting in heat recovery. This process is essential for maintaining a comfortable indoor temperature.

Installation and Placement
