In response to Re: Possible excessive gas usage by water heater
If a water heater is using gas, it is heating water. And if it were heating that much water without it leaking someplace the water heater would either explode or drain the excess out the relief valve pipe. I assume you have a concrete slab house and my experience has been that when an electric or gas water heater starts using extra power, it is due to a water leak in the piping under the slab. The heater is not turning off since the water is leaking faster than it can produce hot water, which is also the reason the water is not overly hot.


: Our hot water heater started leaking after 8 years
: of use. We had it replaced by a similar model
: (40gal, same BTU) by the same company (A.0.Smith)
: on November 20th, 2000. Since then we have the
: sensation that there isn't as much hot water as with
: the previous water heater. Additionally, I received
: a gas bill of over $400 last month. I went back and
: compared our gas usage with the previous year and
: this is what I found.

:
: Usage Period 10/01-11/01 11/01-12/01 12/01-01/01
: 2000

: Usage (CCF) 61 173 275

: Usage Period 10/15-11/15 11/15-12/15 12/15-01/15
: 1999

: Usage (CCF ) 71 132 167

: Before I got the large gas bill we had complained
: to the plumbing company that installed it on two
: occassions (we noticed some water leaking from the
: new one). They explained that the sensation of
: not enough water was due to the colder winter this
: year. Since the water coming into the house was colder it takes longer to reheat after draining the tank.
: The leak was explained as condensation. While both
: explanations seem plausible, the difference in
: gas usage is so startling compared to the previous
: year that I can't help but be suspicious. Also, we
: never seem to have had the sensation of not enough
: hot water in the previous 8 winters with the old
: water heater.

: Could there be something wrong with the water heater
: that could explain this (the jump in gas usage
: coincides with the installment of the new water
: heater)?
