I had put one of these dehumidifiers in my first house and it was a mess

Now my Aprilaire 560 has no moving parts but drips water over a honey
comb, ceramic coated aluminum pad to evaporate in the furnace air. Pad
is rinsed by excess water and would probably last a few years but I
change it every year. Water drains into my French drain which can
handle it and in the Summer condensate from AC goes into same drain.
Never a problem.

Thread just got me to check it and it is working fine. It's as old as
the house, ~40 years.

Sounds like a totally successful dehumidifier.

Except, that it isn't. Oops.

===============================
When I did HVAC installs, my boss used to really
love the flow through humidifiers. Wasted a little
water, but much lower maintenance.


I don't think it uses much water. It only goes on when the furnace is
on and it is only a trickle. My French drain has no sump pump and is
only wet for a few feet beyond the exit. Besides, with a well, I don't
pay for water.

You can also throttle it back if you want to, by partially closing the
valve. AA tells you not to, but I've tried it and haven't seen any difference. It's also not just the water, but the fact that it's heated
water going down the drain. Still, I agree it doesn't amount to much.
I'd rather have a reliable, trouble-free design that uses some water,
than one that has to be cleaned more often, can grow mold, etc.
