We are building a new 4000sf home in Victoria BC. Heating will be in-floor radiant (no ducting). The floors are mostly hardwood with tile in a few areas. The year-round average humidity here varies between 25% to 100%, with a mean of about 75%.
The architect wants to install a whole-house humidifier to protect the hardwood floors. I am reluctant to install a humidifier because (1) We have lived in a similar situation (current house, also radiant heating) with no issues; (2) the mean humidity sounds plenty high to me (this is not a desert - not even Toronto); and (3) I have heard stories of bacteria and mold collecting in humidifiers, which then distribute them to the whole house.
We also have a papyrus plant that drinks a gallon of water a day, and presumably releases the moisture into our environment.
Am I missing something important? Do I need a whole-house humidifier? Thanks
Edit: To answer a comment (I can't seem to comment myself, maybe because I'm a new user on this thread), I don't know what level of humidity is appropriate. I would guess anything above 50% would be fine for any scenario?
