Abstract: . . .  With a gas hot water heater operating at 60% efficiency, it would take 25,043,866 BTUs per year to heat the foregoing amount of water for a family of 4. For a gas hot water heater, then, it takes 25,043,866/100,000 = 250 therms per year at a cost of 250 x $1.74 = $435 per year. Switching from gas to solar saves $435 x 0.70 = $305 per year. This amounts to $6.35 per month per person, or $25 per month for a family of 4.
