Rats, Jim. That wasn't what I was lookin' for!
Sure miss the system we had in our last house. Although forced air, the humidifier was totally automatic and took into account the humidity needs. Oh well. I'm going to noodle this a bit and see if there's a better way. I was thinking of some kind of humidifier pans (verrrrrry long and verrry narrow) that would fit atop of the floor heaters. Could set just above the fins. Will have to do some serious thinkin' on this.
Thanks for your reply.
