    • 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

    • I hate this water heater
Size: 8.4 GPM Color: Gray
The problem is that whenever there is a power outage, the wired low voltage remote will not restart without you turning off the water supply and then repowering the remote. I my case the heater is outside and the remote is inside, they are not close. Rheem acknowledges this system failure but does not have a fix that I know of. Since it is low voltage, it seems that an internal battery might solve the problem. Or I've considered installing a battery backup in a weathertite box. I have four Rinnai tankless propane waterheaters on my ranch and I have NEVER had a single problem. I regret buying Rheem! ... show more

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.

    • DO NOT BUY THIS PRODUCT
Size: 7.0 GPM Color: Gray
Don't waste your money on this product. Rheem is a joke of a company. I've had this unit installed for less than 2 months. Well here in SC, it's been getting down into the 20s the last couple nights. this morning, my hot water pressure was low. So, I go outside and water is spewing out all over the inside of the hot water heater. Rheem refuses to cover with warranty because "the freeze protection only covers down to 30 degrees." What a joke and waste of $800. I'll never use a rheem product again. Stick with Rianni. ... show more
