Built with a white epoxy-coated aluminum exterior, the F1150W offers excellent corrosion resistance ideal for harsh marine environments. The front-mounted heat exchanger allows you to take advantage of engine heat to pre-warm the water, improving energy efficiency and reducing shore power usage. Designed for horizontal installation, this model includes integrated safety controls, a pressure relief valve, and a temperature/pressure drain tube, making it a dependable and user-friendly choice for onboard hot water systems.

The F1150W is the perfect choice if you need a high-volume hot water supply but have a specific installation footprint that requires front-facing ports. It is significantly lighter than the galvanized steel version (F1150), making it easier to handle during installation and better for your boat's performance. The white epoxy finish is specifically designed to match the high-end look of modern marine engine rooms.
To protect the internal aluminum tank from galvanic corrosion, it is highly recommended to install a Magnesium Anode Rod (Whale Part # 74556). Check the anode every 12 months; if you sail in high-salinity waters or stay in marinas with "hot" shore power, you may need to replace it more frequently to prevent tank failure.
