up until the time between WW2 & Korean War most homes in FL had passive solar hot water tanks on the roof... last year we helped a friend put one inside a reflector box on his roof
old water heater that won't hold pressure for standard use painted black
plywood box with tank mounts and reflectors inside with a clear glass top and holes for pipes in one end
supposedly this type of 'frontier' water heater has been used as far north as Wyoming
