Funny that I was talking to someone who has solar heated hot water last night. It does a good job April thru October. I will eventually go to something high efficiency. I wonder what portion of the 500 gallons burned was for hot water? All four of us tend to take long showers. We do a lot of laundry and run the dishwasher often.
