NORITZ Indoor Residential Condensing Propane Gas Combination Boiler with 180,000 BTU/H Input Modulating

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 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 use of 316L stainless steel primary and secondary heat exchangers, which have higher corrosion resistance than traditional heat exchangers for increased durability and lifespan.|Austenite stainless steel heat exchangers allow for greater durability|Liquid propane combination boiler|Unit has a minimum of 18,000 BTU and a maximum of 180,000 BTU/H|Temperature ranges from 90 degrees to 140 degrees (F) for domestic heating|Temperature ranges 100 degrees to 180 degrees (F) for space heating|Unit has ultra-low emissions by a premix burner|3-flat plate heat exchanger for domestic water heating is also made of stainless steel|Fuel saving performance from this unit boasts 95% thermal efficiency|For indoor installations.
