With 65,000 BTUs of power, this thing heats up instantly. It adjusts the power based on the incoming water temperature and flow rate, so the shower water stays at a steady 109°F no matter how much I adjust the flow. Even in the winter, the water gets hot enough and there’s plenty of it. We never have to worry about running out of hot water or rushing through showers. It’s great for comfortable showers in the RV.

This model is a lot sturdier than older RV water heaters. It has two adjustable legs that give it solid support on the RV floor, so it’s not hanging off the door frame. This is especially helpful when driving on bumpy roads – the vibration-resistant design keeps everything secure and working smoothly.

The box comes with everything you need to install it, including a showerhead and hose for outdoor RV showers. The manual is really clear with easy-to-follow steps, so the whole installation process was super simple. After hooking it up to the RV’s 12V power and propane tank, everything worked perfectly.

I love this water heater which has transformed my RV camping experience. It delivers a consistent supply of hot water meeting all my needs from showering to cleaning dishes. The double water outlet is a fantastic feature enabling me to use hot water in the kitchen and bathroom simultaneously without any hassle. I find its compact size fits perfectly in my RV, and the 12V power requirement matches my setup. The controller is simple to use allowing me to adjust the temperature with ease and the freeze protection is reliable in cold weather.
