this is a reply for David and Cecil. I agree that it has been a very mild year. We had temps in the 40's as little as a week ago. Snow just arrived this week. So yes it has been mild as far a us here in the North. In response to the person earlier we tell some of our customers that if you are interested in ice skating and or fishing on your ponds then you can turn them off. But be sure that the ice is safe before you let anyone else on them. You might want to open a hole above the diffuser once you decide that you want to turn them on again, this eliminates creating a mound on the ice and opens the water faster.
Hope this helps
