The question came up a while back about how long a water heater lasts.
Out of curiosity I checked the date code on the GSW (gas) water
heater I installed shortly after we bought this house in 1982, when
the house was 8 years old. It (the water heater, not the house) was
built August 1983
The current water heater was installed on the Canadian Thanksgiving
weekend in 1983 (I believe that's columbus day for the Americans).
So the original lasted 9 years - and the replacement has been in
service now for TWENTY SEVEN YEARS.
Sun? What is the.... OH, you mean that glowing disk-shaped thing in
the sky that is sometimes seen filtered through the clouds? Yeah,
they don't see much of that in the Pacific Northwet.
The tank is an electric model, cranked to thermonuclear temps.
It mostly depends on your water quality. In central Indiana where I grew
up, the burner and clockwork parts usually crapped out before the tank
did. 20+ years was routine.
Guess I oughta check the year on mine, here in SW MI. Pretty sure it is
ten years plus at this point. Seems to work fine, and so signs of any leaks.

Yes they last, and nobody cared about efficency so they were not
designed for it. Gas units get less efficent every year from scale,
not electric though. Most new regular grade Ng tanks only have an EF
rating now of 55-60, and that is their new efficency rating 55-60%.
Then factor in a dirty burner, wasting pilot light and unefficent
design of 20 years ago and you have a bigger gas bill. I pulled out a
20 yr tank and cut it open for fun, it had nearly 13 inches of rocky
scale that was blocking heat trasnfer. My new tank cut my summers gas
bill in half, so there are other reasons to replace them, and if it
blows, will it ruin anything in the basement?
I bet Its under 45% so its crap.
Unless you are paying to cool your house the heat *lost* actually is lost
inside your house ands the heat from the standing pilot gets absorbed into
the water you were going to heat anyway.
Either cheap electricity or expensive gas could sway the cost factor to
electric however usually gas is the cheapest.
It's staying 'till it leaks, and then I'll look at higher efficiency.
Replacingg my 30+ year old furnace with a non-condensing high
efficiency (tempstar 80+) furnace didn't cut my gas bill a penny. It
DID lower my electric bill. So I'm not going to pay a huge premium
for a few points in efficiency. DEFINITELY won't go to electric.
