I use a 1250w floater. Last year I saw a $20 increase on the power bill over winter. I rarely plug in the car, so most of that would be from the heater. (My pond is 18' x 10' x 3.5', 7 koi between 6" - 18"). Making a spa cover for your pond will help cut that down as well. 2x4 frame with 1 1/2" compression board, 1/2" plywood and a good tarp works well.
How much water do you have? How deep is your pond? Less than 3' can be problematic for wintering fish around here. Also, fish under 6" generally don't carry enough body fat to make it through our extended winters without feeding. I keep a 300g holding tank in the garage for the little guys and usually feed them once a month over the winter.
