[C320-list] Water heater continued...

[Adam Weiner]

I should clarify this a bit.  When this problem materialized six years
ago I called Seaward.  Ironically they are located very close to where I
grew up.  They explained that although the problem does not exist in all
units, it is so common that in many newer (particularly larger) boats
there is an extra thru hull for this.

According to them, it does not mean that there is a malfunction in the
valve (which I replaced before talking with them) nor in the thermostat
(although he did offer to sell me a new one, he told me that it probably
would not fix the issue).

Now, the key factor is the amount of engine and/or shore power time.  If
you don't use a lot of either, you won't have the problem.  Again, also,
not all units will have the problem.

I have found that with running the engine about one hour per week, and
turning off the 110 when not using the boat, that the large Coke bottle
takes over a month to fill up.

By the way, tonight will be my 44 sail of the year.

Told me (and I do) the same thing hull 218.  I have more of an issue
with the shore power so when I leave the boat I turn off the breaker for
the water heater.

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
