Smallest ERV unit vs. RecoupAerator
We have a small home (1320 sq ft) in SW Wisconsin, and we are bermed into the hill and using a tight envelope with passive solar, high thermal mass and radiant floor heat (that we may not use very much).
We are going to put in the ductwork for an ERV because of what I've read about air quality and our concerns about humidity control.
I need advice because most of the units are much larger than we need (e.g. RecoupAerator) but have higher efficiencies and lower energy use. I have found the EKO by Venmar but that is only in the HRV model. We have found Broan or Venmar make a small unit that is better sized for our home, but runs on 50 to 150 (Max) watts.
Does anyone know of a smaller unit that has the lower energy use, or do you think the larger unit would be cost-effective in the long run?
