just don't turn the propane on...keep it simple.

no reason to be afraid of propane but don't use it.

Have a 18 ft Jayco and hot water heater went out. Wanting to see if anyone has ever replaced the original with a smaller electric one. Don’t really like the use of propane for anything inside.


If you know you're always going to have electricity why not. I assume you mean a conventional 6 gallon electric heater. It is certainly cheaper than an RV water heater.

A lot of misinformation in this thread. An RV water heater on electric does not take hours to recover, it takes 1 hour (1400 watt element). A conventional residential heater takes less than an hour (1650 watts).

An add in element for an RV heater is an option but will take more than 2 hours or so to recover (675 watts), and if its a Suburban removing the anode rod to install one is not a good idea.


What GDS said is SPOT on. I was going to replace mine with the 6 gallon electric. You have to make sure you have the space needed to do this. With the water lines coming out of the top I didn't have enough space to make it happen. Make sure you do the measuring.

I put a Rheem 10 gal. water heater in a cargo trailer conversion. Pretty sure it was on a 20A breaker and it never flipped. Plenty of hot water for the 2 of us. But we came from a 30’ sailboat, so we were used to taking a “small” shower.
I turned it on right after setting up so no real worry with waiting.
However, a 120V water heater is not cheap.
I would look into the electric/propane unit first if I was to do it again.

The Rheem 20 gallon fit in a 24x24x36 space. It is rated for 2000W so you need to make sure if you plan on using a generator it will do 2000W continuously. I could not find an advertised recovery time for either the 10 or 20 gallon unit.

You could always swap out the element for a lower wattage one.

If you do downgrade to a residential water heater, remember to have double the height available so you can pull the anode rod out the top. Yes, it has one.

The members of this forum crack me up. He has an 18 foot trailer and says he wants to go to a smaller water heater. I'm pretty sure he isn't worried about having enough hot water for multiple showers.
I will agree with one of the posts above. Put in the same size dual use water heater and use electric only.
As for electric not heating up fast enough, we have a 10 gallon duel use. We never run it on propane. Three of us can take showers in a one hour period and not run out of hot water.

Long time between showers ! Of course if the shower is big enough, you could always "shower with a friend" !

You must be a plumber ! Never heard of ANYONE changing an anode, not that it is bad idea.

I just thought it would be better to have an element that could be powered as opposed to one that trips the breaker and provides no heat.

It is true that very few have a clue. The major big home improvement stores quit stocking anodes because folks are irresponsible and destroy much of what they own.

I check the anode rod in my residential water heater every year. I thought everyone did.
If you change to all electric, you are restricted to camping CG with electric or carrying a gen set or being without hot water and heat. I like boondocking to much for that.
