Seaward Water Heaters

All Seaward heaters have galvanized steel exterior with aluminum tank interiors, hold down brackets and ignition protection. Dual wall heat exchangers are front mounted on "F" models and rear mounted on "S" model water heaters.

It's the same, but not the same :)

Replaced 17 year old water heater with this 11 gal. of what I thought was the same make and model. Looks the same. Screw holes for mounting were not in same locations so had to pilot drill new holes for new screw locations. This unit is also a little bit bigger than last one. All connections are in the same location and fit perfectly. No problem installing and connecting it other than where boat manufacturer decided to put it. Works great, just follow nicely written book of instructions.

Same basic design as Admiral.Resued old fittings & improved rust control. Easy old out & new in without any alterations to boat.

I replaced my original equipment round upright heater with this unit when the 30 year old unit started leaking. The newer box design fits well in my engine room. I needed to put a heat sensor on the tank itself and was able to remove a cover panel easily to epoxy the sensor on. Heats quickly and very hot which is excellent for 2 back to back showers each morning. I'm very happy with this product.
