With a bypass unit it uses both. :-)
Have you bought the humidifier already? If no you may want to consider
what units are available. There appears to be a large gap in how happy
owners are after a year or two between brands and models.
Remember the flow throughs only work when the furnace fan or burners( in
some cases) are running. If your furnace is not getting much run time, guess
what, your not putting humidity in the air. Running your fan all the time
might help a little but then you'll be paying more in electricity. Gofish
has it right !
I am not disputing what Gofish said.
My original observation was that the General Aire 81 (evaporative pad), connected to the cold water supply was more than adequate while the Wait 6000 (flow through), connected to the hot water supply did a lousy job.
Steam humidifiers are something that I am not familiar with.
I have to find a distributor in the Toronto area.
Aprillaire Recomends the use of hot water if you are
using the humidifier on the cold air return duct or not geting enought
humidity output.I've had two Aprilaire units and like them both. if you have
hard water or softened water you pretty much have to have a drain type,
other wise you could go back to the drum type.
I'm assuming the manufacturer had you check the water flow from the
discharge to make sure the unit was getting water ?
