Navien Premium Condensing Tankless Gas Water Heater Installation
http://clovisplumbingservices.com/navien-tankless-gas-water-heater-installation/ …. As a Journeyman Plumber with 28 years experience, this is the best product I have seen in years.
Technical support has been exceptional. Every issue that has occurred was responded to and immediately resolved either by phone support, replacements part and even replacement unit… all shipping was overnight.
I truly believe that any negative comments against the Navien Premium Condensing Tankless Gas Water Heater were originated by competition or an installer that did not know what they were doing.
