Tanks For the Memories Nice product , easy to install ; could have provided the nipples for the tank, otherwise, it was a simple installation for a gas water heater. January 28, 2015
easy to install bought this at Lowes. Had it delivered to my home and installed it myself. Easy to set up, fit into the space of the last water heater and it fired right up (within 90 seconds) and stayed lit. Water was running hot in the house after about an hour. January 27, 2015
Good value for the price Was easy to get home and install by myself. Fired up on the first try. Hopefully will have no issues but I just installed it 3 days ago. January 27, 2015
Works GREAT! Easy install and start up Works great & heats FAST! Great Value and Good warranty January 24, 2015
Great value and performance for the money. Great value, has all that you need for hot water. Easy to relight if pilot goes out. January 23, 2015
installed 2 days ago so far so good, i was expecting to spend less for installation but since the old one was over 20 yrs old we had to bring thinks up to code. January 18, 2015
So far, good water heater. Installation was straight forward. Quality seems good, lighting the pilot light was a snap. And I like the status light letting me know the flame is lit, or if there are other problems. January 17, 2015
Great experience with Install through Lowes. Professional plumber I would highly recommend purchasing this water heater at Lowes and having them intstall it. They handle all the paper work including the city permits. No mess, no fuss. January 17, 2015
The controls are hard to read and reach. At my age and with my knees, the controls are difficult to deal with. I would have paid extra to have eye level controls. January 13, 2015
simple not bad if you're not familiar with plumbing might want to have a friend who does January 6, 2015
