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 28,000 BTU/hr, two vent heater is easily vented to bow or rear seating areas while the second 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.
