What Rheem Customers Are Saying
"I just finished installing this water heater in my yoga studio. it serves all my needs, and then some! Even though I have it set on "medium", the water is plenty hot and almost instantaneous. I have used the shower a few times and not run out of hot water. I am very pleased with this unit."
