This product design is good We used it for couple hours after the installation and so far the performance is good and we hope it could be that way in the long used for 6 years or more (beyond the warranty period) and I have to observe the energy consumption in the future how much is the savings compared to my old Heater.

Hidden Code I was excited to get a more energy efficient water heater for the price of a regular one with the gas company rebate, then I installed it. I had another plumbing problem that cause the Fuel Vapor sensor on the water heater to get wet that cause the 7 blinking light lockout. I thought no big deal - dried it out - plug it back in and I still got the 7 blinks. It turns out that there is a secret combination you have to use to reset the controller. Really, on a DIY water heater there is a lockout you can't reset yourself! After 2 hours of searching on the internet, I found that I had to rotate the temperature control between high and low 6 times to reset the controller and it works fine now. Print this in your operators manual and I'd give this water heater a higher rating. May 25, 2015
Nice heater Lowes delivered the heater to to my basement for free. (if they want a delivery fee, insist that it is a major appliance, which by Lowes policy is free delivery. A supervisor can override the fee if the computer sales machine wants to include it). I installed it myself. I had to buy 2 nipples and 2 flexible hoses to complete the job. I had to use a torch to remove some copper fittings that attached the old heater. I also had to install and electrical outlet box near the heater. The new heater was taller than the old one, which required me to shorten the length of the 3 inch diameter exhaust vent pipe by 2 inches. That resulted in my having to drill 3 new holes for the sheet metal screws. You will also have to drill 3 holes in the vent hood to attach the vent pipe. You may be lucky not have to do the cutting and soldering, and make a direct substitution of new for old. You will at the very least need to drill 3 holes for the vent hood. I was not lucky, but was fortunate to have the tools and experience to get the job done. May 23, 2015
Good unit Purchased at Lowe's for about $430 (on sale). It didn't come with the pipe nipples, so make sure you get what you need before you do your installation. Even though this is an Energy Star unit, it doesn't save a whole bunch of money vs. a standard unit (roughly $35 a year),but will pay for the additional cost after about 2 years. I would say it is worth it. I would like to see a longer manufacturers warranty than 6 years. May 19, 2015
