Heat Recovery Ventilators (HRV) and Energy Recovery Ventilators (ERV) are all about ventilation.
The primary purpose of a Heat Recovery Ventilator (HRV) is to expel stale air in a home and bring in fresh air from the outdoors without wasting energy spent on indoor heating and cooling. It allows air to circulate while minimizing energy loss.
What’s the Difference?
HRV’s use the heat in stale air to preheat air coming in from the outside. This exchange helps to reduce energy bills by bringing the air from outside up to the current room temperature. This can be especially useful during those frigid winter months, when every ounce of heat can make a world of difference.
ERV’s perform the same function as HRV’s while also capturing humidity. It keeps your home from getting too humid during the summer season or too dry in the winter, thus helping reduce energy costs by alleviating the load on your A/C units or dehumidifiers.
Both systems can be turned off with the push of a button, giving you control of when you have either running.
Which One is Better?
Both HRVs and ERVs are useful appliances. Above all, your home, climate, and person presences factor into this decision. Keep in mind the and HRV could increase humidity levels during the summer, so if you live in an area with higher humidity and ERV may be the way to go.
