The Navien NPF700-100H5CH is a condensing hydro furnace in the horizontal configuration with a gas input of 14,000 - 100,000 BTU/h. It burns gas in a sealed stainless steel combustion heat exchanger located outside the airstream, then pumps the heated water through a copper and aluminum hydronic coil that warms the air.
