No gas available here...except propane, which is pretty spendy. Our house has Cadet electric wall heaters.220/240v, 2000 watts. Let's see...2 in the living room, one 1600 watt unit in my office, one 1600 watt unit in the laundry room, one 1600 watt unit in each of the 3 bedrooms, one in the "spare" bathroom. (master bath has a combo fart fan, light, heater)
When we first moved in here, those were our sole heat sources. Our light bill ran $300-$350/month...and they just didn't do a great job of heating the downstairs. (they'll drive you out of the bedrooms if you don't pay attention to the thermostat setting)
4 years ago, we installed a smallish Harman P43 pellet stove in the living room. That does a GREAT job of keeping the downstairs toasty warm...and the heat that makes it up the stairway does a decent job in the bedrooms...except when it's hella cold outside.
Our electric bill (all electric house...water heater, cooking, heating) runs around $125-$150 year round since I installed the pellet stove.
I buy pellets by the ton. A pallet of fifty 40 lb bags runs about $250...I get 3 pallets every year when the local lumber yard has a sale. Saves about $1/bag. They have a "pellet bank" where you pay for your pellets, then pick up as many as you want as you need them. I usually get 20-25 at a time. Most of the time, I get 1.5 to 2 days out of a bag of pellets, but when it's REALLY cold, I might go through 2-3 bags in a day. (fortunately, that only lasts 2-3 days, once or twice a winter) I usually have at least 1/2 pallet of pellets left at the end of the heating season...and carry those over to the next year.
Am I saving money? Maybe a bit most months, but the comfort level in the house has greatly improved.
