The Xtreme Boat and Cabin heater is designed to help keep your boat cabin, RV or other small space comfortable during the fall and winter months. This heater features quiet operation, a low profile and stable base that prevents tipping. Drawing air from the top, this heater can be placed up against walls, or on carpeted surfaces without blocking the air intake. The 1500 Watt heat setting will quickly warm your living space, while the 750 Watt setting will efficiently maintain comfortable temperatures. The 6 foot power cord offers more flexibility for heater placement independent of outlet locations.
