Get energy-efficient, endless, hot water at a low installation cost.

The NRCP1112 indoor condensing tankless water heater can provide up to 11 gallons per minute of hot water. It comes with an internal pump that produces hot water faster in both non-recirculating and recirculating applications. It comes equipped with a heavy duty 304 stainless heat exchanger for superior thermal transfer with excellent resistance to scale formation. The Noritz NRCP series can be vented with 2" schedule 40 PVC pipe and operates with as little as a 3.5" water column at the incoming gas line. These features mean you get a relatively low installation cost.

Frequently Asked Questions ("FAQs")

Q1: What is the difference between the NRC1111 and the NRCP1112?
A1: The NRC1111 has a copper heat exchanger on bottom and stainless steel on top. The NRCP1112 has two stainless steel heat exchangers.

Q2: Why would this newer model, the NRCP1112, go from copper as found on the NRC1111 with better heat conductivity, to stainless steel with less heat conductivity? Doesn't that lower energy efficiency?
A2: The NRCP is a condensing heater with the very latest technology. Condensate contains corrosive substances which stainless steel can handle, and copper cannot. Also, calcium will not build up on stainless as it will on copper. This is a big problem if your water is very hard. Overall, the condensing system saves much more energy than the small amount lost with the lower heat conductivity.
