Hot Water heater hoses
 

Hi,
Please forgive the on-topic nature of this post...

I'm about to hook up the "domestic" Hot-water from my new engine (ie
use the engine's cooling water to heat the domestic water). I'm using the
same hookup as for the old engine, but there are two hoses - does it
matter which way the water goes? (ie is there a distinct "inlet" and
"outlet") The HW heater is really hard to get at, and I didn't mark the
hoses before I unhooked them.

It probably doesn't matter but you could always check with either
Catalina or the water tank manufacturer (Raritan?).

Normally the hot water from the engine, would go in on top of the heater,
and out slightly lower ( or bottom)
Vice cersa on the freshwater side... This gives a natural flow through the
system.

Best of luck

Thanks. I might try Catalina (although they've been less than helpful in
the past), but I have NO IDEA who made the water tank - I replaced it
about 10 years ago. They're pretty generic, though - you say Raritan makes
some?

Definitely, hook it up backwards and you'll have an icemaker!!!!!!! ;)

Looking around, I'm pretty sure it's a Seaward F700. I talked to Seaward
and they say it makes no difference. Yay! Don't have to tear the boat
apart to find the HW heater!

Hi Lloyd,
I looked at my tank and the engine discharge flows into the bottom of the
tank through a flow sensor. What the sensor is for I have no clue, but it's
wires go to the main computer box. There is a check valve on the output side
that discharges overboard. (Under swim platform)

I suppose the direction of floe does not matter except for the high loop
(well above waterline) in the discharge hose. I guess the factory did this
to limit any possibility of flooding in case a hose or something else gave
way.

Yes! Cold water comes in at the bottom and hot water comes out at the
top. Getting it backwards can destroy the heating element (which you'll
prob'ly want to use at the dock instead of running the engine).

That's not what his question was.

Oh, well...knowing Lloyd, it would have been his next one. :)

=====================================

I believe that Lloyds heater is setup for a fresh water cooled engine
where the engine coolant recirculates through the engine, heat
exchanger and hot water heater in one continuous loop. That's the
most common type in my experience.

What you are describing sounds like a raw water cooled engine to me,
where some of the cooling water is diverted through the water heater
and then discharged. Assuming you have a wet exhaust, the rest of the
cooling water would exit there.
