I think you got confused with DEhumidifier. Humidifiers are cheap to operate.

  Nope. It's a humidifier that uses resistive heating to vaporize water, and that takes a lot of energy.

    That's like cautioning about the price of cars because you bought a Hummer instead of a Corolla. Drum humidifiers use a couple watts on any central forced-air system. And, since the heating season is there only time you need humidifying on this context, all the "waste" heat is just heating your home.
