This Product has great features. What I like about this water heater is it has an igniter and not a pilot light. March 10, 2015
HAVING ISSUES Positive reviews by others and the electronic ignition feature sold me on purchasing my 40-gal water heater. Installation was easy enough and the directions were fairly easy to follow and get the water heater working - although they were rather substantial. March 9, 2015
this product is efficient it runs better than my old one and i am very pleased February 18, 2015
Seems to be a great product Installed and began using in one afternoon with no difficulties. The manual lays out the installation and start up steps clearly and thoroughly. It is much quieter than my old water heater and seems to maintain the temp better during periods when I am not drawing hot water. I am looking forward to seeing some savings on my gas bill.
