Parts Desk Insights
If your Seaward water heater is no longer heating water but the tank and plumbing are in good shape, a failed heating element is the most common cause — and replacing it is far more cost-effective than swapping the whole unit. This element covers the full Seaward 6- and 11-gallon lineup, so it’s the right part whether you’re running a compact 6-gallon or a full 11-gallon system. Compatible heaters currently available include the Seaward F600 6-Gallon Marine Water Heater, the Seaward S1100 11-Gallon Marine Water Heater, and the Seaward S1100W 11-Gallon White Epoxy Marine Water Heater.
