Easy to install; easy to light; does the job. This product was easy to install (observe the code in your area), and works as advertised. The instructions were clear and concise, better than I have come to expect lately from other manufacturers. March 4, 2014
This water heater is well made in the USA. Works fine. Plenty of hot water. Saves Gas with out pilot light. March 1, 2014
Brand New Installation was a breeze for my plummer lets hope it performs over the years to come February 17, 2014
Seems Like a Quality Produst Good product ,Fair price .A little light on the warranty. February 10, 2014
Excellent model for the price I found that installing this unit was very easy, especially with the clear directions in the installation guide. February 4, 2014
Easy to install and great features I love the electronic ignition for the pilot light. I use to use a match to light the pilot. I only had a minor problem with the gas line but was able to add a niple to make up the height difference. The flue and water pipes were lined up with no problems. I added two unions and one more shut-off value. Overall an easy installation. Seeems to heat the water very fast. February 1, 2014
this is a pretty good product I will know more in around six months of use that's all I can say right now January 21, 2014
woks but noisy, heat the water well, but as loud as an air conditioner unit when it's working. The other water heater that is over 10 years old from another company is not making any noise. January 16, 2014
Perfect for my needs I liked the compact size,fit perfect in the small area that I had avaliable.Good visibility on the pilot light monitor,can be easily seen from across the room.Easy to handle and easy to install. Recovery from extended use is 8 to10 minutes so has cut down on my fuel use considerably.I've noticed that it rarely comes on except when water is being drawn.Great machine. January 15, 2014
