Based on my experiences with hot tubs and the like, I think this would be an inaccurate method. In testing, I think you would find that losses vary a great deal from things like room temperature, floor temperature, humidity, the placement of the cover over the pool and so on. I recommend a much smaller body of water in a better insulated container. - Jed
