The NRCB is the first and only tankless hot water heater and boiler combi 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.
