Hydronic Heater Kits

Extend your boating season into the crisp months of fall and beyond with an Acu-Heat Hydronic Heating System. They work much like your car's heating system. Hot engine coolant is circulated through a radiator and a powerful 12V fan blows air through it, forcing warm air to where you need it most. We offer these systems in 28,000 and 40,000 BTU capacities and in ducted or grilled configuration. The ducted heaters direct heat to cabin, rear seating, and cockpit areas, keeping everyone warm and toasty. They include six feet of duct hose per vent.

The grilled heaters are perfect for heating cockpit areas or cabins. They mount easily in stairwells or cabin interiors and are often used in tandem with a ducted unit. Heaters (with corresponding controls) may be purchased alone or as part of a complete kit. Kits include 25' of 5/8" heater hose and a universal brass engine fitting and hose barbs for a hassle-free installation. A popular option for the ducted units is the Hot Tube Extendable Vent (included with model 2835189), which extends up to 6 feet, allowing placement under jackets or clothing, surrounding yourself with luxurious warmth.
