The heater isn't designed to heat the entire pond, just keep a small hole in the ice. The heaters tend to be a lot cheaper as well and really don't use that much energy. Most are only 100 watts I believe.
When using them, you just need to make sure they keep up with the weather. The pond air pumps work well also, but the good ones tend to be a bit expensive. I have a heavy duty pond air pump and it works nicely, but I use the heater and pump together.
950 GPH in a 100 gallon pond is a good amount of flow. That means your turnover rate is 9.5 times an hour....decently heavy filtration. Is your filter designed to handle that much flow? I know the Fishmate 2000 handles up to 1300 GPH and that's for up to 2000 gallon ponds. Its always good to over filter, but you want to make sure your filter can handle that much flow. It should say on the specifications its maximum GPH.
