  • Great Buy
Color: Black
We had one put in our old Winnebago when the water heater went out and fell in love. When we upgrade to a new camper we IMMEDIATELY put this in, in place of the one we had. This is a MUST HAVE.

  • Buyer beware!!
Color: Black
Defective out of the box. There is no power getting to the control panel from the motherboard. Everything else has power. Sadly, outside of the return window by 10 days so we are out almost $300 for a defective product. Buyer beware.

  • Smaller then expected but does the job.
Color: White
After the 8gal water heater failed in my 5th wheel failed. I wanted something that gave me a longer shower. I followed the instructions, it works greats. Been using it daily for 2 weeks no problems. Everything I needed was included, even the crimpable wire nuts. I hoping this last for a few years as the price was very reasonable. ... show more

  • Nice Tankless Water Heater
Color: White
I've been wanting to try a tankless water heater in my RV that I use for hunting as we boondock camp, and having hot water is nice for cleaning up, doing dishes, etc and I hate having a traditional heater that burns extra propane keeping 5 gallons of water hot. This heater was fairly easy to install - the hardest part was getting the old one out and the opening cleaned up. The remote is a nice feature and makes it easy to set the heater as you want. I haven't used the heater a bunch yet, but in initial testing I'm pretty happy. One good thing with the traditional heater is that the large mass of water helps keep it from freezing during the trip or overnight if the gas runs out. This heater claims to have freeze protection, and considering I use the trailer in the U.P. of Michigan in November, I guess we'll see this fall if it works as advertised. Time will tell if this heater keeps working, and I'll update this review if need be once I've had a chance to run it for a while. ... show more
