Kuuma Products

<h3>About Kuuma Products</h3><p><strong>Kuuma Products</strong> is a brand under Camco Manufacturing with a name rooted in purpose: the word &ldquo;Kuuma&rdquo; is of Finnish origin and translates simply to <em>&ldquo;hot&rdquo;</em> &mdash; a fitting identity for a line built around serious outdoor cooking and marine comfort. From the beginning, Kuuma has focused on delivering high-performance grills and water heaters that can withstand the punishing demands of the open water, while remaining versatile enough for RV trips, tailgating, and backyard use.</p><h3>Built for the Marine Environment</h3><p>What sets Kuuma apart from general outdoor cooking brands is its deep commitment to marine-grade engineering. Every Kuuma grill is constructed from corrosion-resistant stainless steel, purpose-built to endure the salt air, moisture, and vibration that would quickly degrade lesser products. The brand&rsquo;s water heaters take a complementary approach, using marine-quality aluminum construction and TIG-welded interior tanks to resist galvanic corrosion &mdash; a critical consideration for any onboard system. In fact, Kuuma has become the water heater of choice for many original equipment manufacturers in the marine industry.</p><h3>Grill Lines Designed Around Real Boaters</h3><p>Kuuma&rsquo;s grill lineup is thoughtfully organized around space constraints and use cases that real boaters face. The <strong>Stow N&apos; Go Series</strong> &mdash; including compact models like the Stow N&apos; Go 125 and 160 &mdash; features integrated folding legs for flat-surface grilling and easy stowage in tight spaces. The <strong>Elite 316 Series</strong> steps things up with a built-in thermometer, removable warming rack, and a piezo igniter for hassle-free ignition. All Kuuma grills can be mounted to compatible rail, rod, or pedestal mounts, making installation straightforward on virtually any vessel. Every single grill and water heater is 100% tested prior to shipment, a quality-control standard that reflects the brand&rsquo;s commitment to reliability on the water.</p><h3>Beyond the Boat</h3><p>While Kuuma&rsquo;s roots are firmly marine, the brand&rsquo;s reputation for rugged, compact cooking equipment has earned it a growing following well beyond boating circles. Since 2008, the brand has attracted significant attention from the RV community, tailgaters, and home patio grillers who value the same durability and thoughtful design that makes these products work on a boat. Whether you&rsquo;re docking at a marina, pulling into a campsite, or setting up a game-day spread, Kuuma&rsquo;s <a href="/11528-kuuma-products-stoves-cooktops-202596">stoves and cooktops</a> deliver consistent, dependable performance.</p><h3>A Customer-Driven Design Philosophy</h3><p>Kuuma&rsquo;s product development is guided by user feedback &mdash; designs evolve based on what boaters and outdoor enthusiasts actually need in the field. This approach has produced a catalog of gear that feels intuitive to use: stay-cool handles, latching lids, compact footprints, and mounting flexibility are all standard features rather than premium add-ons. For anyone who spends serious time on the water or on the road, Kuuma Products represents a well-earned standard of outdoor cooking excellence.</p>

Product Details

The Kuuma Products 11840 is an 11-gallon marine water heater designed to deliver reliable hot water aboard your vessel. It operates on 120V AC shore power (60Hz / 1500W) while docked, and features a front-mounted heat exchanger that harnesses residual engine coolant heat to warm water while underway — giving you two independent heating methods in one compact unit.

The tank and exterior jacket are constructed from marine-grade aluminum alloy, significantly reducing the risk of galvanic corrosion in saltwater environments. Side-to-side mounting brackets are included for secure installation. All plumbing and electrical connections are front-facing for simplified installation and maintenance access.

Key Features:

  • 11-gallon capacity — ample hot water supply for galley and onboard use
  • Dual heating modes — 120V AC electric element (1500W) or engine heat exchanger
  • Marine-grade aluminum alloy tank and exterior jacket for corrosion resistance
  • Front heat exchanger with 5/8" O.D. engine water inlet/outlet connections
  • 1/2" Female NPT cold water inlet and warm water outlet connections
  • L1 & N wiring configuration — 12.5A amp draw; 15A breaker recommended; stranded #12-3 wire
  • T&P relief valve rated at 150 psi and 210°F for safe pressure and temperature protection
  • High-temperature limiter with automatic reset for added safety
  • Listed per UL 174 and CAN/CSA C22.2 No. 110
  • Side-to-side mounting brackets included

Replacement Parts (MFG Reference): Heating Element #02858 | Thermostat #11930 | High Temp Limiter #11920 | Anode #11916 or #11919 | T&P Valve #10473
