.........The pilot light is not going to keep the water hot or even
appreciably
warmer that the surrounding temperature. ......
sorry but you're wrong
I guess when I was working on my vacant SoCal home that had the water
heater left on "vacation",
that the water was really cold & not warm.
Funny how when I took a shower to clean up before leaving, that the
water was warm enough for a short shower.
Additionally I wonder what energy from the gas that was burned by
pilot did? I guess it really didn't keep the water warm.
Sorry but my experience with my water heater contradicts your
theory.....I stick with mine, the data (10+ years) confirms it and so
does the arithmetic.
When the ambient air temp is in the 70's +, a water heater in an
enclosed space (utility closet or small utility basement) has very low
standby loses. The pilot can easily make up the difference.
The control on OP's water heat MAY be broken but depending on his
locale ... the pilot can & will keep the water water than he
surrounding air.
combustion / thermodynamics.
