It keeps a hole in the ice to allow gas exchange. You are not dumb. Most of us have been down this path so please don't be shy asking. It is not like a pond heater that cycles on and off keeping a six inch hole in the water rather, it heats a very small amount of water and keeps ice from blocking the tube which links the pond to the atmosphere. It is actually oxygenating tremendous amount of water in the pond. Also, don't worry if it 'lists' slightly. It is still working. I don't think it is a good idea to pull it out when plugged in. I am sure it is working. Let it do it's job tonight. It will freeze in place as it is supposed to do.
