The Mariner North Restaurant
The Mariner North is located in downtown Copper Harbor, a small town near the tip of the Keweenaw Peninsula. Six buildings are heated with hot water from a 250,000 btu, water-jacketed Central Boiler. About 40 cords of wood are used during the extended cold season. Alternative heating is either with propane or fuel oil, as the natural gas grid does not reach Copper Harbor.
