Noritz has expanded its line of combination boilers with the new Noritz Residential Combination Boiler (NRCB), which the company says allows for simultaneous residential domestic hot water and space heating and performs at a 95% AFUE.
Its fuel-saving performance allows the NRCB to meet “Energy Star Most Efficient” standards, which represent the U.S. Environmental Protection Agency’s highest efficiency rating. This, combined with an Air-Conditioning, Heating and Refrigeration Institute (AHRI) certification, qualifies for various state energy rebates.
