But if you want to keep something warm, look for "heat tape" in the plumbing section. Or for infrared heat lamps (typically reflector spot type) in the store. The heat tape is designed to keep pipes from freezing up and there's no filament to burn out.

Incandescent bulbs are (were) cheap and convenient, but there are better ways to generate heat.
The problem with "HEAT TAPE" is that they are normally at least 6 feet long, and you only need about 3-6 INCHES of the stuff to adequately warm up a typical thur hull fitting.

That's good information. Unfortunately, where I want to put it, it would be very difficult to insulate the area so the heat tape works effectively.

"Non regulating heating cable: This type of heat tape is regulated by a thermostat. It can be purchased by the foot or in a roll as well. The heating cable can be custom fit to your application because it can be cut to any size that is needed and the ends are then added to the length of cable. This type of heat tape will require a connection kit with an end plug and outlet as well as a thermostat to regulate the temperature."

The lack of space is an insulator. You might need to use more wraps of tape around more times for more concentrated heat. I believe covering with insulation is best, but not a requirement.

OK, Mr Pearson, several of us have been trying to give you the "HINT".

Since you haven't taken it, here is the BLAST.

BOATS ARE NOT DESIGNED TO BE LIVED ABOARD, IN FREEZING TEMPS. PERIOD!

IF YOU'RE BENT ON KILLING YOURSELF, OR SINKING YOUR BOAT, YOUR CALL!

There's good reason that almost 100% of boat owners would never attempt what you're attempting.

Learn from others. Don't attempt to re-invent the wheel, especially since you don't appear to even understand what that "WHEEL" actually is.

I'm done with you.
Good Luck,
Sorry

Chill out, dude. Lots of people live aboard in freezing temps.

Re: Extreme Cold

"The problem with "HEAT TAPE" is that " So, you treat it the same way any sailor treats any line. You never CUT a line, you just shorten up, coil it, wrap it...You take the six foot heat tape and wrap it around the fitting, or coil it up and hang it so the extra heat is there, and then tuck some bubblewrap over it to concentrate all the heat on that part.

The heat tape should self-regulate temperature so "too much" isn't a problem. In the worse case it warms up the rest of the boat.

I just had a mini-reflector (damned expensive tungsten bulb) burn out in less than 200 hours of use, when it was rated for 2500 hours. Would I trust a light bulb to keep anything from freezing? Don't think so. Yes, sailors have for ages. And you just won't hear about the ones who returned to find frozen engines blocks. That why there are block heaters, heated dipsticks, electric engine blankets, and other devices. A whole range of them. That don't burn out like light bulbs.

A light bulb is just the wrong tool for the job.

Re: Extreme Cold

I use a stainless steel Refleks model 66MK boat heater. It has kept my Bombay Clipper 31 toasty warm (even in the recent near 0 deg temps) during the winter months of New Jersey for over 35 years of living aboard. It burns diesel fuel and is available from Hamilton Marine, Searsport Maine.
