So Confused: HRV, ERV, Dehumidifier, Ductwork
I’m gut renovating a 100 year old, 4500 sq-ft, 3 story home (plus unfinished, but in-the-envelope basement).
I’ll most likely be spray foaming and have a pretty tight house.
I’m trying to figure out the HVAC and ventilation plan. I really like radiant heating, but that doesn’t solve the ventilation or AC needs.
I’ve been reading about ventilation needs, ERVs and HRVs, positive and negative pressure, etc.
House is in Sullivan County, NY, where the Winters are zero degrees (F) and the Summers are 100 degrees and the humidity has a range almost as large.
House is 34×45 with 11′ ceilings on 1st floor, 10′ on second floor and 3rd floor is dormer/attic style with average ceiling height of ~7′ (roof slopes down to touch exterior walls and peaks at 14′). Basement average ceiling height is just under 7′.
Should I use radiant heat? Should I go with a ducted HVAC? Mini-Split? Separate AC? Integrated ERV/HRV?
Sure would appreciate some advice.
