A major benefit for contractors looking to further streamline the tankless-for-tank replacement job is the availability of each EZTR model in a Bundle package for indoor installation. Each combo package includes the heater itself, a single vent conversion kit, a flex vent conversion kit (25 ft. of 2 in. flex), an isolation valve kit and a startup guide. This high-efficiency condensing unit is a great solution for a direct tank replacement.

  • Hot and cold water connections are located on top of the unit, not the bottom (like most tank less heaters); this positioning allows the flexible water lines used by the previous tank heater to be quickly and easily reconnected to the new unit
  • Optimizes the perfect air/fuel ratio based on demand for better efficiency with less moving parts
  • Greater resistance to corrosion and scale buildup than other materials, thereby boosting system life
  • Noritz connect app is compatible, allowing for wireless remote control of-heater functions, as well as diagnostic and maintenance reminders. The wifi adapter (NWC Adapter) is sold separately on Homedepot.com.
  • For smaller home applications
  • Flex venting to run through existing B-vent
  • Saves installation time
  • All venting accessories in 1-box
  • Isolation valve kit included
  • Full solution for direct tank replacement
