After market electric water heating elements

My water heater is propane only. Was wanting to get some advice on buying the Lighting Rod or Hott Rod to be able to cut the propane use down to heat water. Is there pros and cons to using these. Would like to hear some feedback on this subject

I have installed and use 2 Hott Rod kits on older coaches we owned, and never had a problem. You have to provde adequate 120V power to the system. That could be a problem depending on how your coach is set up.

A lot depends on what kind of water heater you have. Most recent Suburban water heaters require the use of an anode rod to protect the inside of the tank from rust. If your aftermarket electric heating element replaces the anode rod, you could be asking for corrosion that could cause a leak down the road.

The Atwood wh in my Hurricane has a Hott Rod added. It does work great. The only issue I have with it is that it takes the place of the drain plug, and in my case it very difficult to get out as it is wedged against the gas feed line.

I own the Weekend Warrior FTL 4005 and it has the Atwood 10 gal hot water heater. It has existing wires from underneath the kitchen sink where there is a 110 outlet to the water heater. Was just wondering where you mount the thermostat to measure the temp of the water or does the probe measure the temp of water and shuts off and on when the temp gets to the setting you have set it for?

I own a 1999 Born Free 23RK Class C and like you, the water heater was propane only. I installed a Lighting Rod kit, tapping into an existing 110 wire under the sink, and it has worked flawlessly for us. Sure saves propane!

Most of those heating elements are between 1000 to 1500 watts.. so using 120VAC it would be between an 8-12 amp draw.

I have a Hott Rod that PO installed. It works great. When camping in the summer months (95 degrees plus) I plug directly into the power post to reduce the draw on my 30 amp system. When on generator, during the summer, I use propane to heat water.

I have the same set up asWildtoad and it is a pain to drain and reinstall the Hott Rod element.

I have the Hot Rod in my 10 gal heater and have no issues yet. I have a 50amp system. The only pain is to pull it out when I want to clean the tank. I usually clean my tank every month. I have been using the campground 110 and not usuing my plug under the sink. When you have alot of people taking showers I use propane also to keep up with the heat. Usually takes 10-15 mins to get water heated back up. Thanks for all the advice. Great forum to get info from.
