What gas water heater has an option of a tank replacement without an integral burner?Valuethinker wrote: ↑Fri Nov 10, 2017 4:14 am
I think the consensus is this is not a good idea for reasons of convenience and resale (would put off some buyers, potentially).
New tanks are very energy efficient - you can get one with excellent insulation (one form of loss is via the ground, so insulated feet help). Energy consumption thus similar. Cost of a 40 gallon and a 30 gallon should be similar.
Your main problem may be a change in dimensions *that* could force you to downsize.
The real alternative is to go tankless. A lot of considerations there, for a couple that should work but it will have inconvenience. I am a fan of sticking to what works (i.e. retain current approach, get a new highly insulated tank)-- avoids having to replace the burner.
Here (UK) we have a "boiler"-- the hot water is heated indirectly by the same furnace (boiler) that heats the water in the radiators. So what I mean was "replace the thing that heats the water". Agree it's a totally different bit of kit and if I'd thought about it, I would not have written "burner". I was trying to get an idea across and got lazy and did not think it through
My tank is called a "Megaflo cylinder" and it cost a bomb-- but the heat loss parameters are really impressive. 110 litre is close to US 40 gallon.

.BTW other's have posted about "hot water heater". I have 2 water heaters, but they both heat cold water.
That's a so common bit of usage I think we can wear that? Technically it is not what is happening, but hot water comes out the end .
