Noritz NRCB180 Combination Boiler
The NRCB is the first and only combination boiler on the market that can simultaneously provide domestic 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 NRCB’s use of 316L austenite stainless steel for the 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.
The NRCB has a built-in outdoor temperature reset control and is compatible with a recirculation loop without the need for accessory heat exchangers or controls.
