NORITZ 11.1 GPM Built-In Recirc. Pump - Natural Gas High Efficiency Indoor Tankless Water Heater 12-Year Warranty
NORITZ 11.1 GPM Built-In Recirc. Pump - Natural Gas High Efficiency Indoor Tankless Water Heater 12-Year Warranty
Item # 1030664
Truckline Only. Energy Star

Noritz NRCP series heaters offer the latest cutting edge technology in tankless water heaters. The NRCP features an internal pump that can be used in two different modes. External mode, combined with a return line, can keep the water in the pipes warm resulting in lower wait times for hot water. Internal mode, which does not require a return line, will keep the water within the unit warm to reduce the traditional delay between water demand and the startup sequence. This unit is equipped with heavy duty 304 stainless steel heat exchanger for superior thermal transfer as well as excellent resistance to scale formation. Noritz NRCP series heaters can be vented using 2-schedule 40 PVC pipe and operate with as little as 3.5 water column on the incoming gas line. These features contribute to a relatively low installation cost. All brought to you by Noritz America, the world's largest producer of tankless water heaters.

  • Unit is for indoor and outdoor installations; VCK-NRCP is needed to convert the NRCP for outdoor installation
  • Venting can be longer due to the style of burner, 2 or 3 PVC venting can be used and no dipswitch settings are needed for longer vent runs
  • Intake vent is on the right and exhaust vent is on the left, this is opposite of other DV Noritz tank less water heaters
  • Built in recirculation pump, saving you and your customer money by not having to purchase an additional recirculation pump
  • 2-filters to be checked for debris after the installation is complete, 1 is on the inlet water line and 1 is on the recirculation return line
  • Warranty is not reduced at all with the use of a recirculation pump; 12-years on the heat exchanger and 5-years on all other parts
  • Water and gas leak detection is integrated in the programming of the unit to prevent damage to the unit if it senses either a gas or water leak
  • Customizable internal and external recirculation settings, so you have more options of hot water comfort for the customer
  • Programmable recirculation timer or auto learn, allows the customer to pick when the recirculation system should run, or the unit will learn the customer's habits and automatically run the pump for the customer
  • Dual stainless steel heat exchangers
  • Need to purchase separate outdoor vent cap VCK-NRCP

NORITZ 11.1 GPM 199,900 BTUH Residential Outdoor Condensing Front Exhaust Natural Gas Tankless Water Heater
NORITZ 11.1 GPM 199,900 BTUH Residential Outdoor Condensing Front Exhaust Natural Gas Tankless Water Heater
Item # 152603
Truckline Only. Energy Star

NORITZ is proud to introduce our most efficient tankless heaters, the next generation in tankless technology condensing heaters. This innovation utilizes a dual heat exchanger, a fusion of stainless steel and copper heat exchangers. The 100% stainless steel component captures the residual heat from the exhaust temperature to preheat the incoming water before it runs through the main copper heat exchanger. This results in dramatic reduction of carbon dioxide and increases the heaters' efficiency level to over 93% Another benefit of this technology is lower exhaust temperatures, which means less costly PVC can be used for its venting. A PVC adapter is built into the heater for easy installation.

  • BTU input range from 16,000 up to 199,900 BTUh
  • Maximum flow rate capacity of up to 11.1 GPM
  • Heat exchanger manufactured with commercial grade copper, 25% thicker piping than standard models
  • Grade copper, 25% thicker piping than standard
  • Minimum activation flow rate 0.5
  • Available temperature settings up to 140°F
  • Cold water connection size 3/4 in.
  • Hot water connection size 3/4 in.
  • Gas connection size 3/4 in.
  • Power supply 120 VAC

Item # 1030337
Eco-friendly item. Symbol indicates that the product is part of our EcoSource green purchasing program. Product meets our sustainability standards for one or more of the following high-performance categories: Water Conservation, Energy Efficiency, Indoor Air Quality, and Material Selection. Truckline Only.

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 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
