2.Is this a permanent or temporary installation?

3.Are you referencing a portable propane cylinder such as a 20# grill cylinder, or are you referring to a permanently installed bulk propane tank?

Most natural gas hot water tanks do not convert to propane, also called Liquefied Petroleum Gas (LPG). Propane is heavier than air and most hot water tank burners are not designed to burn this gas safely.

You have to check with the water heater manufacturer for a conversion kit. Also, your local building codes must be followed as far as proper placement of the tank, running the lines, and proper hookup.

Rheem has a model that will convert from natural gas to propane.

Your local propane dealer may have more information for you.

The tank must be specifically designed to use propane as fuel. Otherwise, No. Do not hook up a propane tank. An explosion may result when the gas ignites.

Just don't expect to get much hot water out of a Bernz-O-Matic bottle! That might run your heater for a half-hour or less! But yes, some are made to run on propane, others natural gas. If you can run it on propane, you'd need a 20 or 30 pound tank, minimum. -And OUTSIDE the house, per code.

NO NO NO NO NO NO
If your tank in the house is not propane then you CANT DO IT.
Tanks are made for Nat-gas or propane.
You can buy a conversion kit to change them to either 1
The problem is the orfice in the hot water tank.
Now if you have a propane HWT and you want to use a tank from a grill or something (You can do it and it would work) BUT IN NO WAY am I saying this is a good idea to do.
Im a Plumber 20yrs plus and I have seen people do things likes this and 4yrs ago someone did It and well lets say this He is no longer around to tell any good stories.
Goodluck

So long as the heater is run on propane and you have a regulator for the tank. But I wouldn't trust some stranger over the net... Consult an expert in person before you blow your house up.

Not a good idea, first of all the valves are different and it won't burn right, it may give off to much carbon monoxide and kill everyone in the house. Consider that.
My hot water tank up North, in Minnesota was propane, like everyone Else's but they were also "changed" over for it.

The burner orifice for propane is much smaller than the one for natural gas. If you put propane through a natural gas orifice it likely would form a mixture that was too rich to burn, but if it did finally ignite, it would likely tear your exhaust ducting apart with the explosion and probably light the house on fire.

I would guess that your local or state codes would actually require conversion work on a water heater to be done by a qualified gas plumber.

is the water heater a propane heater? or natural gas? makes a difference, things might go boom! i would do the hook up outside if i were to do it, not inside the house.

You can if the inside water tank has the right orfice, If it was on propane before it will be fine. If it was on natural gas, you will need to go down to the gas company and get the proper orfice for propane.

Yes but, the heater has to be rated for propane.
