Bad, I did not buy this heater myself my neighbor did and installed it for us (my husband and I), the heater has also been a headache. It could keep the water heated and would turn off and I had to go and light the pilot over and over my neighbor would come and check the wiring and could find anything wrong, I finally went to Lowe's because It is a Whirlpool and asked the salesman what would be wrong with this heater since it was about 2 years old.
He mentioned the thermocouples.
I bought one and maybe this will help. I am tired of lighting this sucker everytime I take a long bath or shower.
Reviewer is in unhappy mood. This person is quite happy with that i did get the discount. Please immediately contact the author of this review to discuss bad quality of whirlpool water heater and associated monetary loss in the amount of $500. Lowes needs to offer any options to resolve the issue according to poster's claims.
