Noritz Combi Boiler NRCB199DV-NG Product Description

The NRCB199DV-NG is the first and only combination boiler on the market that can simultaneously provide domestic hot water and space heating for residential applications. These simultaneous capabilities are easy to control and especially beneficial for applications that do not store or deliver heat energy efficiently. A user can, for example, take a shower without worrying about experiencing a corresponding drop in room temperature.

Another industry first is the Noritz combination boiler's use of 316L stainless steel primary and secondary heat exchangers, which have higher corrosion resistance than traditional heat exchangers for increased durability and lifespan. A third flat plate heat exchanger for domestic water heating is also made of stainless steel.

Additionally, this combination boiler and hot water heater includes a remote thermostat for the precise adjustment of output temperatures. The unit also comes with an outdoor reset control with outdoor temperature sensor.

All Noritz combi boilers have an automatic water feeder to maintain your hydronic system’s pressure, filling up with water as necessary.

It also far exceeds the toughest emissions standards. The Noritz combi boiler’s fully modulating burner has a nitrogen-oxide emissions level of only 14 parts per million (ppm), far below the South Coast Air Quality Management District requirement of 20 ppm.
