It's a nice brand and it works well
Would RecommendI love the heater but when I opened the box the heater has dents on it! I don't know if it happened during the delivery. I had no choice but to install it because I didn't have any vehicle to return it to store. I have pictures of the damage as well

Replacement Water Heater
Would RecommendI chose this hot water heater to replace a 12-year old AOS design. The old heater was the same physical size and I was able to re-used the much of the existing plumbing. The old and new machines were almost identical so the task was relatively easy. I expect the same kind of performance of the new heater as the old.

Good Quality/Easy Installation
Would RecommendEasy to install. Highly recommend using two people to load and unload heater if using a pick up truck. Once it was unloaded from truck, I used a heavy duty hand truck to move it into place in my garage and install it myself.
