At Greenbuild: Condensing Wall-Mounted Boiler
February 1, 2010

Rinnai’s wall-mounted boilers use condensing technology to heat an entire home and provide domestic hot water, while operating at up to a 96.5 percent AFUE efficiency. The units are Energy Star-qualified. The units are easily retrofitted to replace traditional, less efficient boilers or can be used in new construction to provide simple, space-saving installations. All seven models feature Rinnai’s exclusively designed stainless-steel heat exchanger.
