You can add a "Hot Rod" element - one example: (http://www.amazon.com/Camco-11673-Wa.../dp/B0024ECCJW). It will heat much slower than on gas or compared to a water heater with built in electric because the element is fairly low wattage (425 watts compared to 1500 for a built in element), but it works.

Many people have used the Hott rod conversion kit successfully, but it may void any warranty from Atwood. We haven't tried it yet since our water heater doesn't seem to use a whole lot of propane, plus I don't know if it would contribute to corrosion.

Take a look at the Hott Rod.

Hott Rod Water Heater Accessory - PPL Motor Homes

I have another question for the Atwood. The plastic drainage plug broke apart on mine and so far I can't find a replacement.
Because the Atwood tank is aluminum it doesn't need an anode, but the drain port is the same as the drain/anode port on the steel Suburban tank. Neither Lowe's nor Home Depot carry a simple plug that size. While at it I'd prefer to find a brass plug to replace the broken plastic one.

Most fg trailers use the Suburban tank and wouldn't run across this problem.

I installed the Hott Rod electric conversion in our '96 Casita and am very happy with it. We spend a couple months in one location in the winter so plugged in to shore power all that time. Then for one month we moved every couple days and it still worked great. Bought it from Amazon. I did buy the switch kit but didn't use it, instead I put in an outlet with a switch. When you install the Hott Rod, there is a temperature sensor that has to go against the side of the tank, so be sure you can get at it. Have to cut away some insulation and stick that sensor against the bare metal of the tank

I replaced the plastic drain plug with a reducer and length of 3/8" galvanized pipe
with a cap, to extend the drain out to just inside the access cover. It makes removing the cap easier, and lets the water run out into a bucket, instead of splashing all over the place

I used the Hot Rod in a previous camper I had. It worked good when connected to external power. However I rarely camp like that anymore so I don't have one in my current camper. I almost always boondock. I probably haven't installed one because it goes where the drain plug goes and makes it a little more difficult to drain the tank at the end of camping season.

Thanks Thom and Radar. I've ordered it from Amazon, but if anyone finds a brass one, I'd happily double up.

Any RV dealer has the plastic plugs . I bought a package of 2 for a couple of bucks . I would be cautious about installing a steel or brass plug in an aluminum tank. There is a reason Atwood uses a plastic plug and not a metal plug . The drain plug on an Atwood water heater is 1/2" NPT , the anode / drain opening on a Suburban water heater is 3/4" NPT.

Atwood uses a plastic plug for a reason. Brass and aluminum do not get along too well. You will get some corrosion from the reaction of dissimilar metals. Stainless steel would be a better choice.

Drain Plug

Hello,

You could probably find a brass plug at ACE Hardware.

I broke my plastic plug and bought a PVC pipe one at
Home Depot... works OK.

I don't think that I would use a brass drain plug myself due to dissimilar metal corrosion caused by electrolysis.
