Let's not forget that dehumidifiers are heat pumps.

You are right, I had never thought about that part of it.

Moving a pound of 55 F 100% RH basement air with 0.0093 pounds of
water vapor up into an airtight house and warming it to 65 with
0.24(65-55) = 2.4 Btu and drying it to 30% RH so it contains 0.004
pounds of water, releasing 1000x5.3 = 5.3 Btu, provides 5.3-2.4 = 2.9
Btu more heat than the electrical energy needed to operate the
dehumidifier.
