<h3>About Kuuma Products</h3><p><strong>Kuuma Products</strong> takes its name from the Finnish word for &quot;hot&quot; — and it's an apt choice. The name is a fitting brand for a premium line of barbeque grills and marine water heaters. As a brand under Camco Manufacturing, Kuuma has carved out a well-earned reputation among boaters, anglers, and outdoor enthusiasts who refuse to compromise on quality when they're on the water.</p><p>Kuuma specializes in high-quality stainless steel marine grills and durable aluminum-constructed water heaters designed to endure the marine environment. Every product in the lineup is engineered with the challenges of life on the water in mind — where salt air, humidity, and constant motion can quickly degrade lesser equipment.</p><h3>Built Tough, Designed to Last</h3><p>Kuuma products feature durable corrosion-resistant stainless steel and are designed for the demanding marine environment. Starting in 2008, the brand also began to receive attention from the home grilling market, as well as from tailgaters and the RV community. That crossover appeal speaks to just how well-rounded Kuuma's engineering truly is — these products don't just survive aboard a boat; they thrive anywhere outdoor cooking or reliable hot water is needed.</p><p>Every single Kuuma water heater and grill is tested 100% prior to shipment. That commitment to quality control reflects a brand philosophy centered on real-world reliability rather than just spec-sheet performance.</p><h3>Marine Water Heaters</h3><p>At the heart of Kuuma's marine lineup are their <a href="/11528-kuuma-products-water-heaters-201162">water heaters</a>. Kuuma water heaters are constructed entirely of marine-quality aluminum to help prevent galvanic corrosion, and all models feature an aluminum heat exchanger and a TIG-welded interior tank. Available in multiple capacities including 6-gallon and 11-gallon models, they can be powered by electricity or integrated heat exchangers. Kuuma is the water heater of choice for many OEM boat builders, a testament to their dependable, long-term performance.</p><h3>Marine Grills &amp; Barbeques</h3><p>When it comes to cooking aboard, Kuuma's <a href="/11528-kuuma-products-barbeques-200131">barbeques</a> and <a href="/11528-kuuma-products-stoves-cooktops-201021">stoves &amp; cooktops</a> set the bar for marine-grade outdoor cooking. Their grills are engineered with high-grade 304 stainless steel to resist rust while providing consistent heat for onboard cooking. The lineup includes the popular Stow N' Go series for compact spaces and the larger Elite series for those who want more cooking surface without sacrificing build quality.</p><p>Integrated folding legs enable easy grilling on any flat surface, and Kuuma grills also feature stay-cool handles and latching lids. Whether you're docked at a marina, parked at a campsite, or tailgating before the big game, a Kuuma grill is ready for action.</p><h3>Mounts, Galley Accessories &amp; More</h3><p>A great grill is only as good as its setup, which is why Kuuma also produces a comprehensive range of <a href="/200646-barbecue-table-mounts-kuuma-products-11528">barbecue &amp; table mounts</a> and <a href="/11528-kuuma-products-galley-accessories-200463">galley accessories</a>. The Kuuma accessories catalog includes grill regulators, mounting hardware, grill racks, totes, hose assemblies, thermostats, and water heater components — everything needed to integrate Kuuma appliances seamlessly into any vessel's galley. Both series of grills can be mounted on any Kuuma rail, rod, or pedestal mount, giving boaters a flexible, secure cooking station regardless of their boat's layout.</p>

Product Details

The Kuuma Products 11810 is a premium 6-gallon marine water heater designed for boat installation, offering dual-source heating flexibility for life both at the dock and underway. When connected to shore power, the 1500W, 120V electric element heats water efficiently; when the engine is running, the integrated front-mounted aluminum heat exchanger harnesses engine coolant heat to deliver hot water without drawing on electrical power.

Built specifically for the marine environment, the tank and housing are constructed from corrosion-resistant, TIG-welded marine-grade aluminum, minimizing galvanic corrosion risks common in saltwater environments. The unit features ignition-protected controls, making it safe for installation in engine compartments and other areas where fuel vapors may be present. A manual reset and pressure relief valve are included for added safety.
