My concern was ice pushing my permanent dock round in northern Wisconsin. I purchased the 1/2HP model. On March 28, 2026, I drilled through 17" of ice, drop in the de-icer and within 12 hours a 20' diameter of ice around the dock was gone - open water. Amazing!
This unit was a godsend! Didn’t get our pontoon boat out in time, and it took care of melting the ice underneath the whole boat
Well designed and simple to install
Bought it for my pond. Constantly frozen temperatures were not allowing my ducks and fish to make it through winter. This provided a large area where the wildlife could still do their thing. Wish I would've purchased this a long time ago, instead of going out and constantly breaking holes in ice. Customer service was also very helpful and answered my questions and call on a Sunday!
