After years of frustration about my neighbor's bubbler, I started using a tarp curtain to contain the warm water to their property. The top of the tarp is wrapped around swim noodles, using tie-wraps to hold them in place. Along the bottom, a chain is wrapped with the tarp and again, tie-wraps are used to keep it there. Some years, I deploy the tarp before the ice sets in, but other years, I've use a chain saw to cut a slot in the ice. That helps install with precision. It works best if the tarp is curved, to direct the moving water back towards their dock. It gives me a week or more longer access to the lake on both sides of the season.
