Device that switches between ERV and HRV?
We live in a 1910 craftsman style bungalow in very northern Illinois (climate zone border 5a/6b) that has undergone some VERY heavy insulation/airsealing retrofits. Now as the weather gets cooler and the air dryer, the inside RH stays VERY high all winter.
We are thinking about getting an HRV or ERV as a remedy. But aren’t sure which to purchase. (I’ve read extensively the blogs/Q&A on here [and elsewhere] regarding them).
The issue is our climate. I would like to preserve the low RH air in the summer when the A/C is on and the outside air is EXTREMELY humid so that would mean an ERV. But, in the winter, we’d like to lower the RH so an HRV would be the way to go.
Does anyone know of a product that you can switch between ERV/HRV modes? (perhaps exhaust only too?)
