[C38] water heater

Mon May 5 08:00:42 EDT 2008

I have a link to a website with some discussion on where exactly to insert
the hot water tank circuit. It stated that at the heat exchanger is not the
correct location, but it should be installed at the thermostat. I don't know
enough to recommend either way, but here is the link.

David,

One suggestion that was made to me at the last haul out was to consider
putting T valves in the engine to heater / heater to engine lines to create
a direct loop from the engine back to the engine when the valves are turned
properly.  Just in case your water heater should fail you still can complete
the cooling loop back to the engine.

Hello David,

Please allow me to offer my two cents here.

The hot water heater does not "rob" the engine of heat.  Only excess heat
goes to the hot water heater if you are running a thermostat.  By putting
the hot water heater between the engine and heat exchanger, you allow the
hot water heater to heat up in a minimal amount of time.  Once the hot water
heater is heated, the engine heat exchanger will then remove excess heat
from the engine.

If the hot water heater interior heating coils sprang a leak, your engine
water would contaminate the potable water system on the boat but most likely
the engine would not overheat because your potable water system would
contain the pressure. You may not know that if you drank the antifreeze
contaminated water though because you would be out of commission.

Most hot water heaters use either stainless steel or copper-nickel  coils so
they are pretty much failsafe.  You are more likely to have a leak from the
connecting rubber hoses than the heater coils in the hot water heater.
There is too much liability for the water heater manufacturers to scrimp on
materials on the interior hot water heater coils.

Thanks for all the info. Max, the diagrams are very helpful. My concern is
that it appears that the water heater is in line with the heat exchanger.
Does this rob the engine of heat? If the water heater and the heat exchanger
are in line, what if the water heater fails - will this effect the engine?
