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!

All good, be sure to ck spigot after removing box

Would Not Recommend

Plumber got installed, turned on water and discovered the plastic drain spigot was cracked and leaking. It took an extra hour and a half to remove the broken end from inside threads.

Buyer beware

Would Not Recommend

We had our first one for only 3 years and it took a crap, AO smith did warranty it so that was nice, Lowe’s was great handed us a gift card and we went and got the same one. Well here we are one year later and the heating element went out, save your money and go with a more name brand hot water heater these ones are junk
