How does hard water cause a water heater tank to leak?

How does calcium cause a water heater tank to leak?

What chemical reaction are you speaking of?

Thank you for your helpful answer.

Wise old man is not so wise. The difference is the warranty length AND the
size/quality of the sacrificial anode that retards the corrosion of the
tank. A longer warrantied gas water heater **will** last longer before it
fails.

Where is this anode? Is it replaceable? A friend has a WH in a cabin upstate
and says he has to replace the WH every 3-4 years due to the mountain water.
Would replacing the anode every year or 2 extend the life?

Thanks

Mine has two.

Sacrificial anodes have nothing to do with the energy source. An electric
unit's heating elements are insulated.

I see that somebody else has suggested otherwise wrt water heaters, but
I do recall car batteries being sold with varying-length warranties, and
as far as I could see it was the same battery, but they punched a
different warranty expiration date depending on the price paid.

Hi, MB
You just showed your ignorance.
Battery has many different quality. Thay are not all same.
First look at their rigidity of casing and weight.
Are they same?

Umm, no, that is not true about car batteries. If you
compare same size batteries with different warrantees (same
store), you will notice that the cranking power or whatever
power measurement they use is different and increases with
the length of the warrantee. A 36 month battery is
different from a 60 month, which is different from a 72
month. You will note, however, if you compare batteries
with the same warrantee, that the electrical rating varies
with the size. So when you shop for a battery, if you pick
a specific size, the longer warrantee will be a more
powerful battery. In many cases several sizes will fit, so
pick the largest size that will fit, not necessarily the
original size or the size of the last replacement.

Hi,
Largest does not necessarily mean the best for the application
if alternator can't charge it full. Structure of battery and
materials used makes the difference in quality.

I can't imagine a car battery where higher capacity is not
better or a car that couldn't fully charge it the same as it
would a smaller capacity battery. If the alternator fully
charges the smaller battery, then it will fully charge the
larger battery assuming the same load. Structure and
materials do make a difference but are largely the same in
any manufacture's basic series of batteries. Anyway, no one
needs more than a 5-year battery. The point is the length
of time of the battery warranty relates to the battery
capacity, not just some added on amount for a warrantee.

Exactly. It's ALL number crunching, and anybody that believes
differently is burying their head in the sand.

It's all sitting in an Excel file in a computer at the
battery/water heater/? company:

They have historical data on how long the product lasts before
failure.

With that data, they can calculate failure rates for the
entire lifespan of an average battery.

With that data, they can calculate how muct to charge for the
"extended warranty" (longer guarantee) so they still make
money on the deal.

Economics 101. Capitalism 101. God Bless America.

Maybe they do that where Minnie shops, but not the places I
shop. If it were just punching in new numbers then explain
why the capacities of the batteries with the longer
warrantees are larger or in some cases the number of plates
and the weights are different.

I no longer recall where I encountered this, but I distinctly remember
the battery having been already taken off the shelf or brought from the
storeroom, and *after that* I was asked how long a warranty I wanted.

Of course it is possible to find batteries with different capacities and
different CCA ratings and perhaps correspondingly different warranty
periods -- and that may even be the more common situation -- but I do
not believe that it is universally and necessarily so

((Snipped))

Sorry for disputing you, but I've never seen it or heard of
it and I've bought quite a few batteries at a lot of
different places. In fact, the only auto item I know of
where you buy different length warranties and the item
doesn't physically change is extended service warranties on
vehicles.

Hey guys, don't be so hard on Tommy Pedophile. You see, his self esteem has
been badly bruised since that Megan's Law listing was made public...


Tommy has proven time and time again that he doesn't know anything about air
filters, electricity, home wiring, appliances, HVAC-R, combustion venting,
and now about soft water and water heaters.

Since there are no Pedophile newsgroups, he just posts here to try to
rebuild his warped reputation.

Why do gas water heaters fail?

They don't study the night before the exam?

I have read in this newsgroup that water heaters with 12
year warranties cost about $100 more than heaters with a 6
year warranty.


I had read that the 12 year warranty models usually had to anodes vs
the one anode in the 6 year warranty model. They know that you aren't
going to actually replace the sacraficial anode.
