[C320-list] Hot water bypass

Wed May 27 06:04:43 PDT 2015

 Mike,
You are right, to bypass the engine coolant lines you have to move out the WH. I can see no reason to not operate with just the fresh water bypass in place. A close friend who sails a Hunter 30 has not connected his water heater for the past 3 years because he is lazy and wants to save time when he winterizes.

If your concerned about someone accidentally turning on the electric WH breaker with no water in the tnk, it is no big deal to disconnect the electrical connection on the front of the heater.? I have pictures of that operation too because I turned mine on after winterizing one year and burned out the element.

Bill

Bill, others 
I don't see any evidence of antifreeze leaking into the bilge at this time. 

However, if I understand what others have written, some feel it is 
dangerous to bypass just the fresh water, leaving the engine side 
connected.  Actually, if I had to bypass both sides of the system, I would 
probably not do it at all right now and get by using bottled water for a 
while.  I think that to bypass the engine side means moving or removing the 
entire water heater in order to get to the back of the unit.  That kind of 
defeats my goal of putting the job off for a while (my wife will tell you 
I'm good at that). 

Not sure what to do with all this................ 

Thanks to everyone for the input.
