Over the past couple years, I've spent hundreds of dollars on LPG. I have also been tired of switching my Atwood LPG water heater on and off to save money, and the unit not working when it's raining. So, I decided to look into electric elements for RV gas heaters. The one here seemed to be the best one I could get for the money.
Installation was straight-forward and simple. First step: read the instructions (and take your time). The instructions were well written, and easy to read, even had illustrations, which came in handy, as I'm more of a carpenter than an electrician. I followed the instructions step by step, double-checked everything, and when I was finished, turned the unit on. It took around an hour for the water to heat up to the pre-set 120F, but once it got there, it keeps it there really well.
I do know that this unit will save me a ton of money on propane. I've had the unit switched on for a couple weeks now, continuously, with no problems or issues, just hot water.
