                Great gas water heater. The hot water recovery rate stands out most because we never run out during back to back showers. I have had it for one month now and it completely meets our expectations for energy efficiency. Highly recommend it.

                The water heater was easy to install in place of my old one. It has functioned well and fit in exactly the same place as the old one. It has the same BTU rating as the old one also.

                Works exactly as described. It was very easy to install with the new water heater as it screwed right in without any issues. So far so good but of course need more time to ensure the bladder holds pressure as designed over a long term.

                Garbage
                I bought and installed it but after the pilot light was lit and waiting 90 seconds then turning the dial to hot the flame would go out and it would flash two red lights indicating the thermocouple was bad. After calling Reems service line all of there solutions were going to take several days and that response was not acceptable to me so I returned the item to the store it was purchased from even though that option was not offered to me.Complete garbage product and customer service from Reem.

                We’re sorry to hear about your experience and understand how frustrating this situation must have been, especially after taking the time to install the unit. The issue you described, including the error indication and pilot behavior, is certainly not what we want our customers to encounter. While some troubleshooting steps and part replacements can take time depending on availability and diagnosis, we regret that the resolution timeline did not meet your expectations. We appreciate you sharing your feedback, as it helps us identify areas where we can improve both our products and customer support experience.

                  The water heater was damaged at the bottom after getting it home to be installed. I had to keep it after being assured the damage wouldn’t affect the installation as the store was closed for the night..
