So next year I will be moving into a house and Im planning on having an indoor pond. Size has not been determined yet but im thinking of using a kiddie pool or stock tank. The basement is cold and not heat efficient. I need to heat the pond but I dont want to raise the electricity bill too much. Im trying to figure out how to heat it the most efficiently. Im thinking if I built and wooden enclosure around the pond and filled the gap with insulation and lifted to tank off the cold floor AND built an insulated lid for it, I should be able to keep it heated fairly cheaply right?
