Having seen different metal pipes joined without isulating joints, they range in terms of how much corrosion. In my house, I have a few and the dissimilar unions have shown some galvanic corrosion but this was after 30 years!
so in all honestly, depending on moisture of the surrounding pipes and formation of dew, etc, I doubt he'll be seeing corrosion anytime soon.
If you seriously want to gauge how much corrosion will occur, you can measure the voltage against a reference voltage from usually copper sulfate.

If a rubber tube bursts it isn't going to matter if you're home or not. Still going to be one hell of a mess to clean up.
This is why I asked him to strip the can and take some pix...
Seam welded 150WPSIG vessel will not bulge out that far without splitting seams. A badly misbehaving pet perhaps?

I actually considered it. However, when researching them online I found that in addition to the HUGE upfront expense to install them, they are still buggy and EXPENSIVE to maintain. the amount they save just does not pay off when you add the initial expense, upkeep, and headaches.

Lowes has a 50 gallon flame lock natural gas low nox water heater for $378. The natural gas tankless water heater is $498.
What is the average annual cost of running a natural gas water heater for a 2 person residence, with an average of 15 minutes per person per shower per day?

I dunno - the PET SEEMED to be functional. I AM curious too, so I'll try to pop it open before 'kicking to the curb"
if I had to guess, I'd say corrosion or weak spot in the inner vessel.

I got the Whirlpool (40 gallon flamelock) from Lowes for $260. The "on-demand" unit they have for $498 only supports ONE application at a time (you choose shower, dishwasher, or clothes washer, but no two at the same time). The larger unit was around $998. Plus - I believe they were the Bosch units. do some google searches and you will find less than stellar reliablilty reports

That is for a very small tankless heater. Not good for a family. You need something closer to $800-1000 for a family size heater. Then you need to add the cost of installation. More than likely you will need to reroute the gas line and change your flu. Which may include adding a chimney liner...
There is more involved than just the price of the unit.

I didn't realize that... I figured the maintenance would be the same as any normal water heater...
When we build our new house (years away), we will probably go with a combination of solar heating and electric tank (with solar/wind electricity generation). Where we're living now we have a natural gas stove and furnace, and at first we loved it, but it gets a little scary when the pilot lights keep going out and the house fills with a gas smell. In our new house I want to put in geothermal / heat pump heating/cooling combined with electric heated water pipes in the floors. And use central air for even temperature distribution, filtration, and (de)humidification. I know, dreaming...

What they need to come out with if they haven't already, is a smaller dual-chamber tank (like 20 gallons) that provides available hot water and water pressure for multiple applications, while quickly resupplying the hot water with an on-demand boiler.
You're lucky you caught it in time. My in-laws had a water heater explode in their beach house (very small house, too) -- repairs were about $60,000, mostly covered by insurance, but my father-in-law had just finished fixing up the entire place because they stopped using it as a rental property. I only saw pictures, but it looked like a bomb had gone off (which it did!).
Never had a hose burst, did have my shut off valves go to leaking though. Just my sort of bad luck.
Playing "can you identify this appliance" with your new water heater pic with some friends. I'm not very encouraged by the results so far.

It is a LUXAIRE early 1950s vintage I think (my house was built in 1951 and I *THINK* this is the original furnace)
It is *HUGE* (about the size of two average refrigerators lying down stacked on top of each other!) Not the most fuel-efficient furnace by any means, but it is so reliable I am reluctanct to give it up.

I looked into a tankless system, it would have cost $1K to install it as a retrofit. It never would have paid for itself.
Tankless in new construction is significantly more practicle, and would pay for tiself.

Damn, wtf? So is this a common occourance?
Why does it happen? Is it from not checking on your heater enough.. the anode is eaten up, and then.. your tank gets eaten, from the inside out?
I installed an Automatic Washing Machine Water Shutoff Valve from Home Depot:

Machine drawing electricity turns the valve on, otherwise it is off. Also replaced hoses with steel braided.
