I rarely am at a marina so I normally don't use the 110 VDC hot water heating
element. But on occasion I do want to but the element keeps failing. Let me explain.
About a month ago I had installed a new heating
element in the Isotherm
8 gallon hot water heater
. I used it for 3 weeks at the marina without any problem. Then I turned it off and motored for 11 hours to a new location/marina. When I tried to use the hot water heater
it did not work
This has happened three times Ö new heater element Ö works Ö go sailing Ö hot water element is bad.
At first I thought that the failure had something to do with the pounding at sea though that should not make a difference, but on the motor
trip to a new marina the seas were near dead calm.
Do you have any idea what is causing my problem?
