Superior GR Series Garage/Shop Heater

GR Series heater with optional deco-grille

The GR series garage/shop heater (by Superior Radiant) is the ultimate heater approved for residential garages and shops.  This infra-red radiant heater emits soft, quiet, comfortable radiant warmth to any space.  The balanced flue construction draws combustion air in through a 4" air inlet pipe.  A 2" pipe fits inside the 4" pipe for the exhaust.  This makes the GR completely self-contained and very efficient.  THE BEST CHOICE for dusty or contaminated areas such as wood working shops.  This heater is also great for covered patios, pavillions and commerical spaces such as restaurants, entryways, commerical workshops and a host of other applications.  To enhance visual appeal, install the optional deco-grille (see above photo).
