Alternate heat source question
 
We have one of these - it only works while the engine is running. While
there is some hot water still in the system after you shut down the engine,
it is not circulating so the water in the system cools very rapidly and is
of little use on a sailing boat.

We have a 30' Islander sailboat that we sail all year round in the Puget
Sound. I'm fine with the weather in the right clothes while my wimpy wife
doesn't like sailing in 40 degrees. Our bulkhead doesn't have room for a
Force 10 type diesel heater. We've used an alcohol stove (wet heat), a
portable propane heater (toxic) and the propane stove oven (costly.) I was
just about out of ideas that would keep my best sailing buddy warm.
Then, a buddy of mine was out with me for the last three days and he came

up
with an idea. He suggested that I pick up a car/truck heater and plumb it
into the hot water heater system. It would provide heat while we're under
way and allow us to go below and warm up once in a while.
Has anyone else installed a system like this and did it work?

Dan--

Right off the bat let me say yes, you have to be sensible using the heating
system on my boat, a Westsail 32. It is a kerosene radiant heater. Yes, in
a tightly enclosed space it can be dangerous, even lethal. So the trick is
to make sure the heated space--the boat's cabin--is NOT tightly enclosed.
Typically we leave the hatch open, the butterfly hatch cracked, and the
forward hatch ajar, so there is plenty of air circulation. The capacity of
the heater is far more than adequate for the boat, so we can afford to
"waste" some heat with the circulating air. In fact, once the boat is
warmed up, we have to turn the heater off and on at intervals, to avoid
getting too hot in the cabin--and it's off at least half the time. Works
for us. Has for 10 years. In short, you use the heater exactly the way its
instruction manual says, and according to all the warnings on the unit--with
plenty of ventilation. We ALWAYS turn the heater off before hitting the
sack, of course.

And that clay flower pot on the cookstove burner is a good trick, too--for a
quick warmup. Same caveats about ventilation apply.

Great sailing in the winter, all right--we sail from Fisherman Bay on Lopez
Island. DON'T give that up!

Cheers, fair winds, and toasty toes to you,

Thanks for you insights. If we didn't love our Islander so much, a Westy was
our other choice. We cruised into Fisherman Bay just last year. We draw
nearly six feet so the entrance there has a pucker factor to it. :-)
Do you know the brand name of your kerosene heater? I've been in West
Marine, Fisheries Supply, Home Depot and a few others looking for a small
footprint kerosene heater. No joy yet.

After a little thought and reading the replies, It ocurred to me
that no one had suggested a small tent heater. You still need to
read the instructions air supply. A small vent to supply
combustion air and a small vent for exhaust is required.

External combustion devices could provide hor water for your
truck heater, for instance, a campstove full of coiled soft
copper tube inside the stove with the lid down, out on deck, with
rubber hoses and a small circulation pump?

As fas as 'alternate' energy sources goes, how about a similar
idea using a wood burner out on deck, with a hot water coil? Or a
stovepipe wrappped in copper tube with a fire log inside? You can
stop a firelog by stopping the air supply.

Now as far as electric heat is concerned, wouldn't it be nice if
we could get sails that were solar cells, or solid wing foils
with solar cells? We could use the juice to make hydrogen, and
use that to inflate a para wing sail. Smaller cells could pump up
H2 during the week, when most boats are parked. The H2 might
come to be a useful way to store energy without heavy batteries.

This raises a question: if you run an electrolysis cell, how
does the pressure in a close system affect the production of
gases? In such a system, would you need to contain the O2 in a
seperate tank from the H2? How do the pressures go, if the system
is let go on running? Would there be more H2, more H2 pressure,
and an imbalance of water heights in the collector tubes around
the electrodes? Would simply venting a little O2 restore the
levels?

Consider this...the coolant temp on an automobile gas engine reached 200+
degrees. Run your water heater that high and it will most likely blow up, not
to mention scald you the first time you even attempt to use it. If a water
heater produces 140F degree water, I doubt you will get more than a few degrees
rise in temperature at 40 degrees ambient temps using an automotive style
heater core.

Hoping to be on the water soon...Dennis

This is true, but the rise may still be worthwhile if one keeps it cheap and
simple.

One could get a small car radiator or heater core and plumb it in series
with the water coming out of the motor going into the exhaust. It won't do
much because the water is only about 120 - 140 degrees but it's cheap,
simple safe, and should make a small cabin more comfortable - at least while
motoring. OTOH using water from a water heater is a waste. Whatever heated
that water would be better used to heat the cabin.

A small propane heater heats my whole house. It is so efficient that one
can *almost* hold one's hand on the metal chimney because the hot burned
gasses spend so much time giving up their heat in a metal labyrinth before
exiting. A 1/10 scale model would be perfect for a boat. I'm surprised
nobody makes one ... or do they?

The propane "furnace" in my motor home is little more than a foot square,
sits in a compartment that is outside the cabin for safety, and provides
forced air heat. One could mount one in a sail locker or a detachable "deck
house" like they do carry-on AC units.

A little ingenuity .....
