Get a professional on the phone and order the right thing. If it were
my time and money I'd spend it paying an expert rather than on
becoming an expert myself.

What "thing"?

I didn't see any air-conditioning systems or heaters that run on 12 volts
there.

Well, I have decided I can use the generator.. and like I said, I am
much more concerened with cooling than heat...

In rural Connecticut? On a rowboat? Sheesh.

No one with a working brain would allow an idiot like you to install a
generator and air conditioner on his or her boat. Well, maybe they have
suicidal tendencies...

If you have a small cabin on a boat can you get a small heat exchanger
that heats in winter and cools in summer that runs on 12 volts? What
kind of system would you use?
No.
Eisboch
So how do they air condition boats and campers?
My smart ass answer was because you said "runs on 12 volts". You would
have to have a battery bank the size of the boat to have enough amp
capacity to run a heater or air conditioner for very long. A small AC
unit will draw roughly 8 amps at 120 volts, so figure more than 10 times
that using a 12 volt compressor (if they made one) or running it from a
12vdc to 120vac inverter.
Generating enough heat BTU's would be a similar current draw. 12 volts
is simply unrealistic.
Air conditioners on boats or campers run from either 120 volts and in
rare cases, 220 volts.
The power is supplied from a genset or shore power.
Campers usually have either a heat strip in the AC unit and/or propane
heating systems.
Eisboch
Heat pumps too.
Forgot that. Reverse cycle combination AC and Heat. But not for 12vdc.

Ok, so I need to run a generator, no problem, I have one. What's the
best way to go from there? I see a lot of stuff out there on Google,
any hints about configurations and brands.. I am much more concerened
with cooling than heating. Heating I can figure out later...

Don't forget to place that generator properly in the cabin and aim its
exhaust towards your face.- Hide quoted text -

Just can't stop yourself from being a nasty asshole can you? Man, with
your attitude toward everyone and everything, you must have had one
****ed up childhood. Did you mom or dad beat you a lot? Or was it just
everyone else that beat you up on the way home from school for
thinking you're better than everyone else? Only a low life scum like
you would go around wishing death and injury on people. And of course
you only do it while hiding behind usenet so you don't get your fatt
ass kicked.


Well. He was "different" from the other kids.

No.

Huh?

For cooling, have a fine mist of water go into the air upwind of the boat.
Just like outdoors in Vegas.

Heating is more difficult, as it takes much more energy. If your boat is
inboard and motor running maybe grab the heat from the motor?

If a device takes 110VAC, use a converter but know that heaters take a lot
of juice to run. If the boat is big enough, maybe a propane furnace? But I
don't think that would work on a 20'.
