Addy I would not be too worried, your winters are very mild, here my bottom pond the ice gets to be so thick I can walk over it, and I am NOT a small person at all! (Big but quite fit). Wayne might have a big air pump so that just could be fine, over the heater. Just cause I don't know any people who had success with air pumps, does not mean they don't work. Some of the people I know may have not been checking the pond every day during extreme cold spells, maybe they forgot that in the winter there can be lots of evaporation and let the water level get to low? When the air temperature gets very cold, combined with open water created by a heater, then you get the "pot of hot water in the stove effect", so lots of evaporation happens when the air is - 40 and the water is zero and warmer, around the open water holes. You can see the stream rising when its cold, so I run a hose out the bathroom window and top the bottom pond off twice a week for sure in the extreme cold, if not more!
