[C320-list] Water heater continued...

[JimC320 at aol.com]

Chris,

If your water heater is putting out water thru the pressure relief "Safety " 
valve something is not functioning properly. You should not need to put a 
bottle to collect water or have water going to the bilge normally. I have Hull 209 
and Have had no issues like this. The set up in the boat is no different from 
your home water heater (other than the two methods of heating, engine or 
electric).

The problem could be; 
1) A bad pressure relief valve;  
2) they put a valve on with wrong pressure rating (i.e. to low, but this 
would be doubtful.)   
3) A faulty Thermostat controlling the electric heating element causing the 
water to over heat (most likely). 
4) or If you connect to shore water, the shore water pressure is to high (un 
likely as you would have probably noticed that). 

If you leave your Hot water Heater  on all the time, while connected to shore 
power,  Turn off the heater breaker at the boats electrical panel and leave 
it off for a while and see if you still have the problem. If the problem goes 
away its most likely the thermostat controlling the electric element.

Can someone confirm and/or explain the below post:

b.    For reasons too long to go into here, but as explained to me by
the representative of Seaward who manufactured the water heater, the
pressure relief valve on the water heater should be connected to a fitting
that is connected to a hose that goes into a collection bottle.  I use a 2
liter former Coke bottle and it fills to the brim nearly every couple of
weeks.  Imagine 2 liters of water going into your bilge every two weeks!  Of
course, you have to remember to empty it out.  While you are at it,  Check
the inspection port on your water tanks.  Mine were so sloppy that when the
takes were even half fill, water was leaking out when the boat heeled.


Does this affect all years and hulls?  Is there a better work-around?  Is 
this why some owners put an expansion tank in?

Thanks,

Chris
