Heater Craft 3 Vent Complete Kit 300 Pro

The three vent heating system - 4/48 Warranty

Smaller, lighter and faster the team at Heater Craft has done it again. We have redesigned our industry leading marine heater and increased air flow by 8%, made it 3% lighter, and 5% smaller. The 40,000 BTU/hr three vent heater is easily vented to bow and rear seating areas while the third can be ducted to the drivers seat. Our heaters are perfect for a late night boat ride, warming up after a swim or simply extending your season on the water. When it comes to heaters no one does it better. Included with each new heating system, Heater Craft backs the product with our 4/48 limited warranty -- 4 years, 48 months. 


The 300 Pro is a complete heater system and includes everything needed for a professional heater installation including heater hose, clamps, hardware, vents, switch, and installation instructions (see below for detailed list).
