Raypak Digital Gas Heater — Residential

The Digital Gas Residential line spans four BTU sizes in two heat exchanger materials: copper models run 199,500 to 399,000 BTU, while cupro-nickel versions of the same four sizes are rated slightly lower, from 180,000 to 360,000 BTU, trading peak output for corrosion resistance. All eight configurations hold 82% thermal efficiency and share a 120/240VAC electrical platform, differing mainly in cabinet width (20 to 29 in) to match BTU size.
