Could your pellet stove use a lot of electricity? It probably has electric ignition, a fan to circulate combustion air and maybe a fan to circulate indoor air. What about your water system? Do you have a reverse osmosis system or other water conditioner that could use a lot of electricity? Is your garage or other quasi-outdoor space heated? How many people in the home? Is your home poorly insulated?
The pellet stoves don't use much electricity other than for the fan. Ignition is very efficient and only takes about two minutes most of the time. The water system is idle most of the time. Pump in the well pushes the water to the tank and maintains pressure. We hear it kick on and off when we are using the water, but not otherwise. There's no conditioner or filtration system (our well water is the freshest and sweetest water you've ever tasted! I miss it when I am away from home). The garage is unheated, and only opened and closed twice per day when we go to work. There are only two of us humans here, three large dogs (Newf, Saint, and Leonberger) who prefer to be outside most of the daytime hours, and two cats. The house was built in 1985 and probably is in need of insulation in the attic, and I wouldn't say it is poorly insulated, though, to be honest, I have no idea what's in the walls. We use only led light bulbs, dry the clothes in front of the pellet stoves in the winter and line dry in the summer, and generally don't use much power. Our total utility bill averages about 200.00 including the water which is from the well (and therefore free), sewer, which is septic (and therefore free except every five years or so when I have it emptied/serviced). I looked at installing a propane furnace a few years ago, but the numbers didn't support it. We don't cook as much as we should, so the stove isn't eating up much energy. I do work from home on Thursdays and Fridays, so that could make a difference, though I only really heat my office on those days. The hot water heater is relatively new (2011) and efficient, but we have an older refridgerator (2001). The washer/dryer are newer, high efficiency models.
In comparing my total bill to the ones that folks are posting, I am feeling a little better about my total costs of running this house. The bill I posted was the only bill I have to pay every month (other than the Internet and satellite). I love where I live here in the mountains, but there are drawbacks... I still do not have high speeds for my internet, for example, and they are not planning to upgrade our service in the near future (top speeds below 3000). Netflix barely streams sometimes and we have no digital cable service available so must use satellite (Dish) for the TV. When it rains, we lose internet service because there is so much line degradation between us and the nearest node. Last Sunday I had to go outside and knock the ice off the satellite dish so I could get a signal to the tv so I could watch the Broncos...
Thanks to all of you who have posted your bills. It helps to see what others pay for their utilities across the country. It reinforces my goal of moving someplace with warmer winters and less snow!
