On the subject of water heater wear and tear: does anyone turn the water heater off when not in use? Ours seems to heat very quickly. Corrosion is a chemical reaction, which goes faster at a higher temperature. I don't have a textbook to look up the q10 of rusting, but if it were 2: 140 F - 70 f= 70 degree hotter. 70 / 1.8 = 40 C.So 2 to the fourth power is 16. corrosion goes 16 times faster if heater on. If water heater on 4 hours/day, it would corrode about 5/24 as fast as 24h/d. plus less heat to fight w ac if used.
