FEATURES

THE NEW BREAKTHROUGH IN COMBINATION WATER HEATER BOILER TECHNOLOGY

The NRCB is the first and only combination boiler on the market that can simultaneously provide domestic and space heating for residential applications.

316L AUSTENITE

STAINLESS STEEL

The NRCB's 316L stainless steel primary and secondary heat exchangers have higher corrosion resistance than traditional heat exchangers for increased durability and lifespan

SIMULTANEOUS OPERATION

OF DHW AND HEATING

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.

ULTRA LOW EMISSIONS

BY PREMIX BURNER

It also far exceeds the toughest emissions standards. The unit’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.

Another industry first is the NRCB’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.
