Have you heard about a ventilator from an HVAC dealer before, but didn't really understand the purpose of the product completely? A ventilator is part of an overall indoor air quality strategy. Its job is to replace stale indoor air with fresh air from outside without losing all of the energy used to condition the indoor air. A ventilator is like opening up a window in the middle of the winter without losing heat energy and humidity. Too good to believe? It's true! There are two types of ventilators - read on:
Heat Recovery Ventilator
A heat recovery ventilator (HRV) brings fresh air into your home while exhausting stale indoor air in an equal amount. A heat exchanger core inside the unit conserves heat energy from escaping into outgoing air, thus protecting your energy costs.
Energy Recovery Ventilator
An energy recovery ventilator takes it up a level by also transferring humidity. Like the HRV model, a heat exchanger core conserves thermal energy from escaping into outgoing air while the ERV model can also transfer some humidity into the incoming air. For summertime use, an ERV model can remove humidity from the incoming air.
The important thing to remember about all indoor air quality options is that they are not mutually exclusive. A ventilator cannot perform the job of a UV lamp, and an air cleaner cannot perform the job of a whole house humidifier. You do not have to implement everything to experience results, but overall HVAC efficiency and air quality benefits the most from all four options integrated into your system.
