Whale Water Systems

<h3>About Whale Water Systems</h3><p>With roots stretching back to <strong>1810</strong> and headquarters in Bangor, Northern Ireland, Whale Water Systems has spent over two centuries refining the art of water management for life on the move. Whether you're outfitting a sailboat, a motorhome, or a caravan, Whale has built an enduring reputation as one of the world's most trusted suppliers of low-voltage water, waste, and heating systems. Today, as part of the broader Brunswick Corporation family through the Navico Group, Whale continues to bring engineering heritage and modern innovation together in every product it makes.</p><h3>Purpose-Built for Marine, RV &amp; Caravan Life</h3><p>What sets Whale apart is its singular focus: delivering reliable water and heating solutions designed specifically for the demands of off-grid and mobile living. Unlike general plumbing brands, Whale engineers its products around low-voltage DC power systems, making them ideally suited to boats, campervans, and recreational vehicles where conserving power is just as important as conserving water. From compact <a href="/7648-whale-water-systems-water-heaters-201162">water heaters</a> that deliver hot water efficiently without shore power dependency, to precision-engineered <a href="/7648-whale-water-systems-pressurized-water-system-tubing-fittings-200807">pressurized water system tubing and fittings</a> designed to handle the vibration and movement of life underway, every Whale product is built with the mobile user in mind.</p><h3>A Complete Water System Ecosystem</h3><p>One of the greatest strengths of choosing Whale is the ability to build a fully integrated water system using components from a single, trusted manufacturer. Whale's <a href="/7648-whale-water-systems-float-switches-200426">float switches</a> keep bilge and tank monitoring reliable and automatic, providing peace of mind whether you're at anchor or on the road. Their <a href="/7648-whale-water-systems-showerfaucet-mixers-200946">shower and faucet mixers</a> are thoughtfully designed to balance hot and cold water delivery in tight spaces — a hallmark of marine and RV bathroom design. And for everything that holds a system together, Whale's extensive line of <a href="/7648-whale-water-systems-plumbing-parts-accessories-200786">plumbing parts and accessories</a> ensures you can maintain, repair, or expand your water system with confidence.</p><h3>Over 200 Years of Engineering Expertise</h3><p>Whale's longevity in the industry is no accident. The brand has continuously invested in research and development to meet evolving standards for safety, efficiency, and ease of installation. Their products are widely recognized for tool-free push-fit connections, durable materials that resist corrosion in salt and freshwater environments, and designs that make DIY installation accessible to boat owners and RV enthusiasts alike. When you're miles from the nearest marina or campground service center, the reliability of your water system matters enormously — and that's exactly the scenario Whale has been engineering for since the nineteenth century.</p><p>Whether you're upgrading an aging water heater, replacing worn fittings, or building out a new pressurized water system from scratch, Whale Water Systems offers the depth of product range and the proven track record to get the job done right.</p>

Product Details

The Whale Water Systems S1100 Seaward is a compact 11-gallon marine water heater designed for reliable hot water production on boats and RVs. This dual-function heater features both 120V AC electric heating and a rear-mounted heat exchanger that can utilize engine coolant for efficient water heating while underway.

Key Features:

  • 11-gallon capacity aluminum tank for corrosion resistance in marine environments
  • 1800-watt 120V AC electric heating element for shore power operation
  • Rear-mounted dual-wall heat exchanger allows engine heat recovery
  • Durable galvanized steel exterior case protects against harsh marine conditions
  • Integrated aluminum hold-down brackets welded directly to tank for secure mounting
  • Ignition protection design meets safety standards for marine installations
  • UL certified for quality and safety compliance

The dual-wall heat exchanger design provides an extra layer of safety by preventing contamination between the engine cooling system and potable water supply. The combination of electric and heat exchanger heating options provides flexibility for hot water production whether docked at the marina or cruising offshore.
