  • Impressive
Size: 7.0 GPM Color: Gray
I owned a competitors it worked This is very nice technology Safe and very efficient I'm sold... One thing is the company parts department is lacking... I called to get the cover for pipes long wait time 55minutes got transferred to warehouse they said yes we have 450 in stock... Cool can I get one? Yes go online and place incart select buy... You think I didn't already try that? Anyways it said in-stock placed in cart than said no longer for sale. Called next day waited again long time the said I'd have to buy a whole install kit I didn't need said okay went to buy it and wouldn't you know it unavailable. I'm very understanding but this is just a cosmetic pipe cover for a brand new unit. What if it's a important part? Heater 5 stars customer service 1 star Could be a deal breaker for some But I've never called competitors customer service I'm sure it's just a similar run around Best heater I've owned ... show more

  • Remember to flush annually.
Size: 7.0 GPM Color: Gray
Replacing a different model of the same brand. All the connections matched without major modifications and installation was simple. Exterior mounting location. Looks to be durable. For the sake of warranty, I utilized a contractor.

So our contractor proceeded with install today. When complete he couldn't get rid of Error code 11. The machine was working the gas was working. Here's the thing . On their help line. OUR CONTRACTOR WAS ON THE PHONE WITH RHEEM FOR 39 MINUTES! THEY SAID IT WOULD BE ANOTHER 60 MINUTES FOR SUPPORT! THIS IS NOT SUPPORT. ... show more

  • FINALLY FULL SHOWERS WITHOUT ANY HANG-UP. DELIGHTFUL!
Size: 7.0 GPM Color: Gray
Been using it now for several months. Such a difference from the old one, well worth the price. Responsive, reliable and sensitive to on and off demands.

  • Handy for a food truck!
Size: 7.0 GPM Color: Gray
Fired right up when hooked up to Lp and water. Cool design for outside mounting. Installing was interesting as the port for Lp says “GAS”…so I worried I received a natgas version. Was feed port for the Propane as ordered. I would still label these as Lp for Propane and Natgas for the other to avoid worry and confusion! Otherwise good so far ... show more

  • Difficult
Size: 7.0 GPM Color: Gray
Not 1/2 compatible despite their claims. No error handling for out of propane situations. Only 140F, and must be turned on ahead of time. Wasteful design vents off unnecessary heat rather than reducing propane flow
