These heaters use hot water from your engine's water circulation system to supply heat to remote locations in your boat. These are Heater Craft's largest, most powerful units. They can be used in boats up to 40 ft. A larger space is needed for the unit and the routing of the vent hoses. This heater is very popular for tournament ski boats and aluminum jet boats. Optional Hot Tubes mount in bulkheads or under seats and look like regular vents, but include an extra 6 ft section of hose which can be pulled out, directed where you need the heat, and then stowed back in the tube when not in use.
