Commercial water heater in home

I bought a used water heater at an auction (at a defunct Grainger
warehouse). Model G91-200-1.
Here's a link to this model's description:

I bid on it without thinking too much, because it looked expensive. I
would like to ask if a heater like this can be used at my home.
My home water heater is old and needs to be replaced at some point,
and I thought that it would be a very nice high end replacement,
providing a lot of hot water.
The heater that I bought was installed in 2011.
How can I evaluate its condition (I know that it works, but this is
all I know), and generally can this be used at home? I am quite
ignorant about plumbing and water heaters, I only installed one of
them in my life (at my warehouse).
Thanks

Got yourself a heck of a deal there Ig. Should work just fine at home. Now your women can take unlimited showers and never run out of hot water :)
I assume you already have natural gas and adequate room to install it.

Not only women, I want to take long hot showers. I have a great high volume shower head in the basement.
I think so, yes. I have residential gas supply at low pressure and 3/4" gas pipe.

91 gallons! Now that would be a great unit for an in floor heating system.
Heck, it might even make enough hot water to deal with my niece and her 45 minute showers...
To check it over you would drain it disconnect it and look inside with a good light or better yet an inspection camera. As long as it isn't full of crud and the anodes and such are good you're good to go.

You could fill it with water with a hose and see if it leaks.
In case you don't read the political junk, what did you learn in Russian school about Lenin's New Economic Policy? We studied that period in fair detail in High School. jsw

I thought you said it was old. Did you mean 2001?
That will be very inefficient for household use, Ig. Sell it and buy a new tankless gas heater. They're extremely efficient but cost 2x to 3x that of tank heaters. If you can make a grand off the big one, you're all set.

Rinnai is the best rated company on the market. Check for rebates from both Illinois and Federal sources for increasing your efficiency and lowering your utility bills. I think you get more for upgrading to gas from electric.

It does not leak for sure. I was more concerned about sediment and crud build-up inside.
I did not learn all that much in school -- maybe a chapter -- but I then went on to read a fair amount about Russian history, it was always fascinating, like a detective story.

It will if they waste hot water all day. Otherwise, it will be highly inefficient. A tankless will pay for itself (gas savings) in a year under those conditions, I'll bet.
I have a lower-flow, higher-pressure shower head and love it. It beats the soap off my body and gives me a tingle, but doesn't waste water. I take very short showers, too, you wasteful bastids.

Ig could do something the rest of us can't because our heaters are too small. Set the temp to just above shower temp maybe 110 degrees. Considerable improvement in efficiency and he won't run out of hot water.

That's only if you don't -get- one for weeks, son. ;) For those of us who shower daily, quick is sweet.
And, speaking of sex, I haven't had any for so long, I can't remember WHO gets tied up...

Right. Then Iggy can get legionnaires disease. Water in the tank

=============== That's a theoretical, unproven problem, based on an old report from Canada. Remember that our public water supply has been treated to disinfect it. I can't be giving specific health recommendations here, but look up the temperatures where the bacteria stop multiplying versus where they die.

"And while there is a very slight risk of promoting legionellae
still considered safe for the majority of the population."
Untreated well water is different.
I leave mine at the minimum setting unless an ice storm is predicted, then I set it to max to make it stay warm longer without power and sterilize the tank.

Hey , my camper W/H is set up that way ! Only problem is that it's only 7 gallons , and that means short showers unless you need a cold one .

Probably won't be very efficient. Pour a couple of gallons of white vinegar in with some hot water and let it sit for a while to loosen any scale and flush it well.

OK, a couple observations. 590 Lbs dry weight plus 91 gal of water weighs 1318 Lbs! Can your floor take this weight? Second, can your flue take 199K BTU without burning down the house? My water heater has a 3" flue connection, I think. This thing needs a 6" flue, and it burns more gas than the furnace on my 2600 sq. ft. house, which is 138K BTU, I think. Third, it apparently needs electricity for the draft blower and safety controls, so you get no hot water during a power failure.

One of you knows the right way... always tell your date to bring a lunch, because its going to take all day.

I put in a sink spray head on an extended hose to wash the dog and liked it myself so much I removed the fixed shower head. It puts the blast of hot water right up close and shuts off when releases, wasting no water while I soap up.
