I would love to, but I've had my Uncle, who is an electrical engineer crunch the numbers for me, and it seems that in a flow-through system that heating becomes really inefficient. The water just doesn't stay in the tank long enough to increase the temperature very much. Currently the water is replaced in the tank about four hours. This means that most of my energy goes to heating the discharge water. If I turned down the nozzles to .25 gpm instead of 2 gpm I would have a better ability to heat the water but the water quality would start to suffer. It's a Catch-22. Warm water or good water. I've got my choice. When I move to the farm it will be easier to do because I'll be able to visually monitor the water much more closely and I'll get a little gutsier.
