PA House made of stone - approx 6500 sqft. Six people and a dog.
Radiant in floor heat under hardwood floors. A/C through the duct system.
1. I want to control humidity year round. I am comtemplating a ventilating dehumidifer (Therma-Stor Ultra-Aire) for the summer and a steam humidifier during the winter (looking for product recommendations). Both of these systems would use a/c ductwork - part of which is in uncondition attic space. I would imagine that the "uncondition" part is problematic, I just do not recall why?
2. This house has 3 wood burning fireplaces. Do i need a ventilation solution (hrv/erv) or is there going to be alot of air already flowing in and out? I would characterize the building as being tight. I cannot seem to understand if bigger houses with more occupants need less or more ventilation or if it matters at all.
3. For additional air quality, i am considering media and uv filters. any best practices on this topic?
