So, my buddy bought an after market add on electric hot water heating element to his LP Gas fired hot water heater then shamed me into buying one so I can "keep up with the Jones's" lol. He and I have a friendly rivalry regarding who has a certain after market goody on their RV, and if one buys something the other just has to have the same or bigger or better lol
I was reluctant to buy one because I didn't what to break my neck getting under the cabinets to cut away insulation to mount the thermostat against the aluminum tank (like other units I've seen) . Then I'm searching E Bay and find one (Hot Shot Lightning Rod RV Water Heater) with the adjustable (90 to 150 degrees) T stat that simply zip tie mounts to the heaters external relief valve which is soooooooooooo much easier to mount. My LP Gas Heater is an Atwood (no sacrificial anode rod like Suburban) so I had to remove the plastic 1/2 MPT drain plug and install the 120 VAC heating element in its place. I used Teflon thread tape so its easy to remove for normal winter draining yet seals fine. Then all I had to do was supply switched 120 VAC down to the t stat which wires to the heating element (wire nuts for easy removal for draining). I TRIED IT OUT AND IT WORKS FINE. They are only like 400 watts so heating and recovery time takes a while, but they eventually bring the temperature up to the t stat setting.
The reason to have one is we stay at some camps that have electricity yet we are NOT billed separately for its use. THEREFORE when there we can heat water with the electric element and NOT waste our LP Gas. Yet to be determined is if and when we go ahead and keep the LP heater on (can use BOTH at same time no problem) since it has a much faster recovery and can extend shower time because it kicks on shortly after the shower starts. In other words, if the gas is left on the second shower can come much quicker plus the first will have hot water a tad longer. If the wife has enough hot water WITHOUT the Gas being left on, there's less need to keep it on, unless I need my shower shortly afterwards (then Gas will have it hot much much sooner) .
Well I also added an Oxygenics water saving shower head and a China Toilet, so I'm ahead of my buddy for a while at least lol
The RV is put to bed yet not winterized, I'm thinking Florida and Antique Tractor Shows and Bluegrass Festivals yayyyyyyyyyyyyyy lol
Ol John T and all in Indiana (except when at Crater Lake as in the picture)
