Bought and installed July 18th. Working good so far. Great delivery guys! Disappointed that we had to pay 35 dollars delivery charge while we do have a lowes credit card.

Basic No thrill budget in stock heater

This heater is a basic great budget heater. If placing in an area where if something goes wrong the water will not do damage. Didn’t need the 200 or 300 series with all the up to date smart phone apps etc. Would have like to get the one with longer warranty but it had to be ordered and I needed it the same day. Easy to install.

dented too badly to use!

Would Not Recommend

Before I could even get the box fully cut open, I saw the top-back of the unit was damaged. Upon further inspection, the back and bottom are also damaged. The box is just flimsy cardboard, with no reinforcement, and provides NO protection for the unit.

It Lasted A Year!

Would Not Recommend

Bottom heating element burned out after exactly one year of use. Usually we get nearly ten years out of a water heater. I am thoroughly disgusted. I am completely done with the quality of appliances Lowes sells. Total junk. I am going to replace the element myself, and forgo the mind-numbing run-around I would get with the "warranty" process. I totally regret paying $509 for this boat anchor!
