I'd think this would be OK to use on your boat as long as <i>you're</i> on the boat to monitor it. The idea of an open flame is unsettling, but I also know how small those tea lights are (we've got one of the Ikea bags of half a million as well). I've used a small candle in a tin can with holes punched to heat up a tent before, and that worked OK. This would be a far more efficient method though. Make sure you use ceramic pots...
I agree, David. I wouldn't leave an open flame on the boat unless I'm within an arm's length of it. I've been a potter in my life and have a few pots that I've made that will work well and be a bit more attractive than the old red clay flower pot.
I think you're gonna need a lot of candles and pots. Edit: did some quick research and found out that a tea light candle puts out slightly more energy than a 75w bulb. 26 candles would be similar to a small space heater except for the volume of combustion products you would be breathing, think carbon dioxide and carbon monoxide, not to mention the fire risk.
That was my thought - the CO the candles produce is pretty dangerous. You never see it coming. And tomorrow night is going to be 10F or -11C. I wonder how many tea lights I'll need?
Someone has been watching the links Dylan puts on the TSBB.. Buy a Mr. Buddy heater for your boat for when you are on it (they make them for indoors)...
If you can get electric, get a nice utility bulb 40w type, and drop light, and plug it in, to keep the insides above freezing when you are NOT aboard.
