I'm sure some smarty-pantsy engineery type is gonna come in and give me a longwinded thoroughly accurate explanation that will tax both my intelligence and my attention span, but I gotta know anyway- how come you measure both a heater's ability to heat and an air conditioner's ability to cool in BTUs? It seems sorta confusing. I can have a heater on my boat that puts out 12000 BTUs and an a/c unit that puts out the same 12000 BTUs. shouldn't one of them have a + or a - sign in front of the number?

Which makes me wonder- If I have a heater putting out 12000 btu's and an a/c unit putting out 12000 btu's on my boat, both pumping away at the same time, does that make it hotter or cooler or does it just hover around the same temperature? or will it cause a black hole to open up and swallow my boat?

I re-read it. This is the condescending part. It belittles his opinion based on his meager post count. Just because he did not post does not mean he has not been reading - and forming informed opinions - for the last two years:

I don't intend to make a big deal. Everyone occasionally posts things that rub people the wrong way - me too. But I did not misread it. It's condescending no matter how many times I read it.

But I'll let it go. Petty annoyances like this are not worth my energy.

I did not intend to be condescending, and didn't realize it came across that way. Thank you for the heads up.

I gotta start using smileys or something.

Remember Steven Wright back in the '80s? "For my birthday I got a humidifier and a dehumidifier. I put them in the same room and let them fight it out."

No sweat - it happens to everyone, especially me. Often I get called on it, especially on boards where's I'm the moderator.

"how come you measure both a heater's ability to heat and an air conditioner's ability to cool in BTUs?"
Because they are both heat transfer devices and you are measuring the British THERMAL Units, the HEAT, they produce.
Your air conditioner does not produce cold, it produces HEAT on the exhaust side. Or more correctly, it transfers HEAT from one side to the other. When it moves the heat outside, you call it an air conditioner. When you reverse the heat flow...that's also called "reverse cycle" heating, and yes, there are systems that work in both directions--making the "inside" hot or cold.
Still comes down to how much HEAT they move or produce, so it is still British THERMAL units.

It sure would make good reality TV if little gray men came down one night and stole all the air conditioners south of the Mason-Dixon Line. Somebody buy me seats on THAT 50-yard line! Or better yet, not on that line...just someplace way cooler north of that.

Cold good! Heat bad! Humid heat, worse! Leave it to the gators and bugs!

We never use the A/C when away from the dock. But at the dock there are days when the wind is non-existant and things get HOT below. Besides, we like contributing to global warming!!!!

I like having A/C on the boat.

Anyone who wants to be holier than thou on the subject is invited to come sailing with me tomorrow. Looks like a good day - high temps in the upper 30s.
