Great value, reasonably priced My water heater started leaking and I needed to replace it quickly. I was looking for an inexpensive unit and one that would fit in the confined space I have in the closet where it is installed. I wanted a water heater that was shorter than the one I replaced because of tight overhead space, but it couldn't be much bigger around. This unit fit my requirements perfectly Once I lit the pilot and started heating water it took minimal time for me to get water hot enough for a shower. July 22, 2014
was installed easily Like the electric start for ease of turning on vs a pilot and a match. Heated water quickly on first fill. Time will tell if I get the 19 yrs I got on the last heater. July 21, 2014
What i wanted!! Read a lot of reviews were people think more connections should be furnished. Each water heater will be different. Just take the time to find out how tall the new heater is compared to the old one. Then you can have a good idea what you need. From pickup to turn on was about 3hrs which 45 mins. was travel time.

Complicated but good value You can install this heater yourself but we had a contractor do it. My major dislike is the complicated pilot light mechanism which is not very clear as to how to re-light and maintain. Regardless, a good value. July 20, 2014
very modern and up to date product from the time i removed the product from the box everything went very smooth during instalation. the instruction manual was very easy to understand. i really liked the gas control because i did not have to lie on the floor with matches to light the pilot light. great product.

I have confidence in this brand. Affordable, built by a company I trust based on my many years as a consumer of this brand. July 16, 2014
easy insallation and start up instructions replaced old whirlpool gas hot water htr. with new one. Old unit was still working after 14 years but needed to unhook it to install drywall behind it to acquire fire rating between garage and family room. Decided might as well update .Never had any trouble with the first one try whirlpool again July 15, 2014
Cant beat for the price For 325 dollars you can beat this water heater, and on 50 $ more to get an additional 5 years warranty. That’s 11 years total for 375$ you can’t beat that. Easy install simple water heater that gets the job done. July 14, 2014
