Nick,

How can a dehumidifier produce mor heat than the equivalent of the
electricity it uses. A heat pump does that because it extracts heat
from outside. A dehumidifier is usually self contained...the whole
thing is all in the same space. All electricity consumed should be
converted to heat. Even though it converts the water vapor to liquid
water, the total heat is still there because it never left the room,
only changed form.
