Kuuma Products Water Heaters

Kuuma Products Marine Water Heaters: Built for Life on the Water

When it comes to hot water aboard a vessel, few names carry more credibility than Kuuma Products. Kuuma — a word of Finnish origin meaning "hot" — is a brand by Camco Manufacturing that has become a go-to choice among serious boaters for one core reason: these water heaters are engineered specifically for the demanding realities of the marine environment.

Explore the full range of marine water heaters to find the right capacity and mounting configuration for your boat.

All-Aluminum Construction That Fights Corrosion

Salt air, humidity, and constant moisture are relentless enemies of any onboard equipment. Kuuma addresses this head-on with a water heater lineup constructed entirely of marine-quality aluminum. Every unit features a TIG-welded interior tank and an aluminum heat exchanger designed to resist galvanic corrosion — one of the most common causes of premature water heater failure in marine settings.

This all-aluminum approach keeps weight low while delivering the structural integrity needed to withstand years of use at sea. It's no accident that Kuuma has become the water heater of choice for many original equipment manufacturers (OEMs) who specify these units directly at the factory.

Dual-Source Heating: Dockside and Underway

One of the standout features of Kuuma marine water heaters is their dual-source heating capability. A 1500W electric heating element lets you heat water comfortably when plugged in at the dock using 120V AC power, while an integrated heat exchanger taps into engine coolant heat to keep water hot while you're underway — without drawing a single watt from your electrical system. This flexibility is essential for cruisers, liveaboards, and anyone who spends extended time away from shore power.

Available Capacities and Mounting Configurations

Kuuma offers water heaters in several capacities to suit different vessel sizes and crew needs, including popular 5-gallon, 6-gallon, and 11-gallon models. Each capacity is available in multiple mounting and heat exchanger configurations — such as front mount with front heat exchange, side mount with front heat exchange, and front mount with rear heat exchange — giving installers the flexibility to fit the unit into even tight engine room spaces. Both 120V and 240V electrical options are available across the lineup.

Quality Assurance You Can Count On

Kuuma's commitment to reliability goes beyond materials. Every single water heater is tested 100% prior to shipment, meaning each unit that leaves the facility has been verified to perform before it ever reaches your boat. That level of pre-delivery inspection is uncommon in the category and reflects Kuuma's reputation as an OEM-trusted supplier.

For boaters upgrading older systems, Kuuma also produces replacement parts compatible with legacy Force 10 water heater models, making it a practical one-stop resource for both new installations and repairs.
