Replacement Hot Water Heater

Has anyone replaced the original equipment Seaward 11 gallon hot water tank? If so, how hard was it removing the old one, and with what did you replace it? I think mine might be starting to corrode.

We just replaced ours about two weeks ago. Seems like a lot of them are failing. It came out pretty easily. We disconnected the plumbing from the bottom of the sink and that made it pretty simple to get it out. We went with an eight gallon IsoTherm as a replacement. Seems to work great. Insulation appears to be much better than on the old Seaward. Good luck with it.

Steve – we replaced ours 2 years ago with the exact same unit. It took a solid half day from start to finish.
