I have a 33 years old house in Bedford, Nova Scotia, Canada. The existing air exchanger is out of order and need to replace with something newer. Question is should I get a HRV or ERV system.
As I understand:
- HRV only recovers heat
- ERV recovers both heat and humidity (C$200 more)
That kind of easily makese sense to go for an ERV system so that in winter it doesnt get too dry and in summer it doesnt get too humid inside the house.
But at the same time it may not make significant difference depending on the weather in my location. Thats where I need an expert opinion or someone already have a previous experience on this.
Question is: Which one would be a good choice to go with HRV or ERV? How can i make the decision?
