Would Recommendonly installed a month and so far so good we shall see. The guys at Lowes were very helpful and polite. None on the floor but in stock on the high shelf and they worked quickly to get one for me then checked me out right there. Now that was easy!

HORRID EXPERIENCE
I Purchased this hot water heater on. July 8th of 2026. When they delivered, I noticed the box was broken at the bottom. I asked about it and since they weren't installing it, they said, "when you open the box, if you find damage, just call Lowe's."
