Stand alone Humidifer system with Duct?
We'd like to improve the humidification of our house, the humidity is in the 20% range throughout this winter and just too dry. The sticking point is that we have a radiant boiler for heat (cast iron radiators) and an air conditioning system which is in the attic. I have been doing a TON of air sealing in this house (build in 1950) and going to do blown in cellulose in a month's time when I'm done with the attic. Realistically I don't want to use the a/c system for humidification because there is no water up there and it's cold (and turned off) in the winter. It would be feasible to run a small duct system in the basement (not yet finished) and into the 3 bedrooms and the living room from a central location with water and power. I could fit a 6" duct in the chase that I have to make, but not much larger. Is it feasible to run a humidifier with a fan that kicks on with a humidistat? Basically at the start of the line would be a blower or fan inside a square duct, humidifier above and then trunk off to the 4 locations. The run would be less than 30 feet to the 4 locations I'm thinking, and I could use metal (not flex duct), but there wouldn't be a furnace to dry out the duct. I could even just run a single line up into the large living room if the humidity would spread out.
The whole point is to get humidification in the entire house, instead of room by room humidifiers which we have to refill. We have pretty hard water so steam would be out of the question. I don't have a problem with maintenance of pads etc... as long as it's just 1 humidifier instead of 4.
Has anyone ever seen something like this before? Any other ideas? Thanks
