Just got my City of Loveland electric bill today -- 808 KwH for December!!! -- 35% higher than normal. Geez...
Tracked it down to two things -- one obvious, one not...
- Christmas lights -- my battery bank is offline at the moment, or else I would have run them with my gen and PVs. Plus we went with traditional "big bulbs" for the outside trees this year, along with the old-style mini-bulbs we've had for years instead of switching to LEDs for the indoors.
- Ran into a problem with my CNG furnace this month. Now, you're probably asking, how can this drive up my electricity consumption? Here's how:
a) The main blower was wired incorrectly, and apparently had been for sometime. The medium-speed AC winding finally quit running, but was still drawing tons of electricity when the furnace attempted to start it. Switched it over the the high-speed heater winding, and all is good again. I will have to watch the motor for the rest of the season, though, as the run capacitor and start windings are probably going to die -- and I'll have to replace the motor in the spring (new gen project?).
b) The ignition system would light the gas and heat up the combustion chamber. The control board was programmed to fire off the blower within 180 seconds; however, since the blower wasn't running, the combustion chamber would overheat and kill the flames. But, because we have decent natural flow in the house (plus a mini exhaust motor), the chamber would cool down in 3 minutes and call for the ignitor to fire again. Basically, the igniter would fire every three minutes until the house eventually warmed up -- probably didn't use up any more CNG than normal but lots of electricity (plus probably took several years of life off the igniter).
Just when I thought I could afford Christmas presents for the family this year... (not to mention that, because of all the snow and ice, I have to pay for a gas tank repair on my wife's car). Damn.
