Industry leading low flow activation with a minimum flow rate of .26GPM and minimum activation flow rate of .40GPM ensures hot water is received even in low demand situations. Ultra Low NOx burner meets SCAQMD rule requirements of safety with low emissions. While our exclusive Guardian Overheat Film Wrap prevents our units from reaching the dangerous temperatures others can.

Included are a digital remote control and 10ft. of thermostat wire. As this unit is for use outdoors no venting is required.

Works great
Pattern Name: Water Heater
This replaced my old discontinued Rheem RTG-64XLP after a part on it broke that I couldn’t find. It was easy to swap out the old pressure release components and I didn’t even need to hook up the control panel. Just plugged it in (actually had to solder a plug to the bare wires) and heat was perfect temp for my needs (tiny house with indoor and outdoor showers and one kitchen sink). THE BEST PART, so far, is it froze solid for like 5 days and was totally fine! I’m amazed. I’ll update this review if I end up plugging in the old control panel to confirm it’s comparable. Also, bought this one scratch/dent for a couple hundred less and still have been VERY pleased with it. For those on solar: The heating element cuts on at about 32F and pulls about a 100watts when plugged in with inverter on. The heating element regulates itself decently by cutting on and off. It might cut off based on temp, or could be a timing component too. I couldn’t really tell. When it froze solid I had it plugged in with power, insulated the unit and the water lines, and was letting faucet drip/run… it still froze up, but my whole water system is above ground (not buried) and it got abnormally cold here in NE Georgia. ... show more

This is a great water heater.
Pattern Name: Water Heater
We have a 550 sq. ft. cabin. We have a full bath and a kitchenette. I also have a dog bath. This has not ran out of hot water yet. Even with long showers and long dog baths. It's been great. We have 80 lb propane tank feeding it, and we have not had to refill yet. It's been almost 3 mos. It was relatively easy and straight forward to install. ... show more

Defective unit
Pattern Name: Water Heater
A disaster. My contractor installed the unit, it didn’t work so we brought a Plummer. It was telling us error 12 that means there was little gas coming in the tank so I paid the Plummer to change my plumbing and in the end it was a defective unit. Amazon window closed a eeek ago. So I’m stuck with this unit! ... show more

Buy some thread sealer
Pattern Name: Water Heater
Make sure you use plumbing tape and apply a good thread sealer. I also would recommend to install it close as possible to your lines feeding the house, otherwise you should buy a recirculating pump. Once it was connected it worked by simply pressing the on button. Absolutely love the endless hot water, especially for a family of 6. ... show more

It works.
Pattern Name: Water Heater
Just make sure you get the correct one. LPG and natural gas are different units and do not work with the wrong gas. Hold the up button if you want it above 120F
