Why Choose the Whale Seaward 11 Gallon Hot Water Heater with Front Heat Exchanger F1150W?

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.



Maintenance Pro-Tip:

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.
