It comes down to, you have a steam humidifier that has run for two years without service. I guarantee you that it is loaded with deposit. Loaded with deposit, the humidifier will still come on and pull the same amps, but not produce even half the rated capacity.

Thanks for pointing out my errors. You are right. .2 ACH is an air change in 5 hours. That is 5 air changes in 24 hours or 15 lbs. of moisture per day.

My guess is that with radient cabinet heat loses, 66% of the heat goes to evaporate water. One lb. of water takes 1,050 btus of heat to evaporate. So maybe 3 lbs. of humidification for 1.4 kw. per hour. This is 5 X 1.4 kw X $.10/kw X 30 day = $21 per month if the home has .2 ACH.
If the home has .4 ach double that or $42/month. Thanks for straighting me out the details. The fact remains, low occupancy homes need some humidification.
Bear Rules: Keep our home <50% RH summer, controls mites/mold and very comfortable.
Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
Use +Merv 10 air filter. -Don't forget the "Golden Rule"
No problem. After reading ascj's post, I bet he's hit it on the head if the house is, indeed, as tight as the OP says. It is unclear whether the OP just had the humidifier installed this Winter, or if he's had it this whole time, and just this season his electrical usage has spiked. If it's the former, then that still leads me to believe that the house is not as tight as believed. Maybe he can clear that part up for us.
