I’ve been reading, reading and reading about the various ERV options. Once I think I’ve narrowed it down, I read a new article or a new model has be released. What is the latest thoughts on the ERV market ranking them from best and also value?
It seems like Zehnder and UltimateAir are the primary unites installed in a Passive House. These are the two on top of my list. However, I’m trying balance the value question and budgets always get pinched. The Broan, Venmar and RenewAir report decent specs on the HVI.org site. Is anyone able to rank or provide insights into the following units? Or add one I’m missing?
1. Zehnder ComfoAir 350
2. UltimateAir 200DX
4. RenewAire EV200
5. Panasonic Intelli-Balance 100
6. Broan ERV (model?)
7. Venmar ERV
I like equipment that is stupid simple and efficient, easy to maintain / change filters / find parts. I also like the idea of a boost mode while taking showers and a night time bypass during the cooling season. The flex pipe if the Zehnder is cool but not a primary selling point for me.
