Depends where your at, and how bad the winters are.

You can not beat a stock tank heater. 1500 watts doing its best to keep
your pond at 35 degrees. Not cheap, but it works when the others fail.

You should have that as a back up, if everything else fails.

Who has the link for the dude with the indoor water heater that pumps
