Right now our DHW is heated by oil. As near as I can figure I'm using at least 1 gallon/day for hot water ( 80 degree rise x 8.4 x 200g/day) . It comes to about 135k btu/day. At 350g of heating oil per year I've got an incentive to try an trim it down.
If I do the numbers on what I can get from a panel I'm only looking at 20k/day on an average day. Not enough to flub up my roof and waste 4 grand.
Am I missing something?
