50 gallon gas water heater recommendation
thanks to all

Doubt if you are going to find that. Is the old water heater 18" in diameter? is it larger than 30 gallon?
With all the new efficiency standards and regulations, does anyone make 18" of any size?
I predict you are going to be doing some ductwork in the near future.

The 50's I've had from Bradford White were I think 22" going from memory. I know it's in that neighborhood because of my basement stair with.
I'm guessing tankless isn't an option due to piping or the meter?Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

Will be hard pressed to find a standard 50 gallon that is no more than 18" wide. Not even a standard 40 gallon.
Aosmith GCB-40 is 18"
And that is with most of the insulation removed to accommodate the 18" diameter and provided externally for you to wrap around the tank after installation.
You can extend hot water availability by increasing the temperature and adding a mixing valve at the outlet.

Hi @zepfan , Do you have any photos of the setup? Sometimes there can be work-arounds. Also, are there any places close by, where the piping and vent could reach? The heater will need to be replaced again someday, and easier access would be nice for that eventuality and any service in the meantime.
Yours, Larry1 -

Not gas, but HTP makes a 10 gallon electric that would work. Maybe a couple of them in parallel?0 -
Bradford White 40 gallon RG140T6N is 18"
Rheem Performance Platinum Induced Draft 30 Gallon XG29T12XR60UO has a better first hour rating and recovery than a standard 50 gallon apparently and is 17.75" https://s3.amazonaws.com/WebPartners/ProductDocuments/A4C263BA-2A21-4535-9047-62181E3CB766.pdf
Professional Classic Plus PRO+G29-60N RH70 ID is similar and same diameter https://s3.amazonaws.com/WebPartners/ProductDocuments/A60D9868-BEEF-4BDE-9301-EBC0243CA4A7.pdf1 -
Easy. Rheem heat pump water heater, seal off the flue and put it wherever you want.

I’ve seen it done. Any room to hang a 40 or 50 gal electric awh from the ceiling? If so pipe a 30 or 40 gallon awh in series with it. No need for wiring the 50 gal, it’s a holding tank. A little taco circulator tied in for constant temperature and now you have 50 to 60 gallons of hot water before the cold starts to dilute the temperature.0

Thanks to all that responded. I am just going to remove and re install the duct. Replace it with a 50 gallon that matches what is currently there. The gas meter is no large enough for tankless, plus there are only two occupants of the home, with no whirlpool bath tub. I did have a question about the mixing valve that @dko mentioned. What do you normally set the dial to on the gas control when one of those are installed? c, d or very hot? I have only installed those on electric water heaters, and have a job where another contractor removed a 75 gallon gas heater, and installed a 50 gallon in it's place. The homeowner runs out of hot water on occasion. I was going to install the mixing in hopes that it will resolve the issue. Thanks to all0

If you're doing this professionally you would set it for roughly 120F at the faucet(s) after running for a while.
Be warned, a few Bradford White's I've installed ran about 130 on "normal". I run them at 140, but it's in my own home.Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

I was referring two two different jobs, the first 50 gallon was for a home with only two people with no large tub. The second job is one where a 75 gallon was taken out by another contractor, and a fifty gallon was installed in it's place. The second job is the one where they do have a large tub and run out of hot water on occasion. I was going to install a mixing valve on the second one. Thanks to all that responded0

My now very long hair runs out a 50.EBEBRATT-Ed said:Two people shouldn't run out of hot water with a 50 gallon gas and no large tub. Wondering what they are doing? A 40 should be plenty.

the answer to the tank temp if you are trying to get more hot water and using a thermostatic valve is as hot as it will go if it is a consumer tank. You only get a bit more by storing the water hotter but the thermostatic valve needs a certain minimum differential, usually around 10 degrees, between the hot in and the mix out to regulate properly.zepfan said:I was referring two two different jobs, the first 50 gallon was for a home with only two people with no large tub.

I can run out with a 50 if I try.EBEBRATT-Ed said:Two people shouldn't run out of hot water with a 50 gallon gas and no large tub. Wondering what they are doing? A 40 should be plenty.
Yet, we had a family of 3 survive with a 20 gallon 120V electric for a few months. We made due with what we had.
Saying what should be plenty is kind of impossible. Everyone is different in that regard.Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.
