I posted this question under engines form and didn't get a response. Maybe it's more appropriate to this formum.
I have a Seaward hot water heater that can use either 110v or engine hot water to produce faucet hot water. Last year the fittings on the tank that accepts engine hot water corroded. I purchased another Seaward and want to bypass the engine heating element altogether and use only the 110v element for heating. My question is this - is it necessary to cap the engine hot water element. If it is necessary, do I have to fill the element with water/antifreeze (wet cap) or can I just dry cap it.
