Maintenance costs for HRV/ERVs

user-719615 | Posted in Mechanicals on

I am considering using a high efficiency ERV that uses a rotating wheel type heat exchanger. Someone told me that this type of design is much more maintenance intensive compared to other HRV/ERVs that use a crossflow or counterflow heat exchanger core. Does any one have any data or experience to support or debunk this claim?

    You're not getting any responses so, even though I've got no first hand experience with ERV's, I'll offer the obvious.

    Any mechanical device that relies on a motor, belts or other drive mechanisms, bearings and seals is going to require more maintenance and cost more to operate than a similar device with passive elements.

    I've had one cross flow unit running on a clock timer with only filter maintenance for over twenty years and I've had one that was on a user controlled switch in the master bath that needed a new fan motor after 8 years. Replacing that motor was a pain but not all that expensive once I got all the right parts together. No complaints or maintenance beyond filters on the others I've installed but I don't know what their service history is either.

    I've only installed one of the dessicant wheel units and have lost touch with the owners of that house, it was quite a while back. I think it was made by Honeywell and it seemed not as durable as the others I had done so I went back to cross flow after that, my understanding is that that model has been discontinued.
