Winterizing it just makes more sense, along with keeping cabinet doors in front of them open to keep warm air circulating around them.

Has anyone ever had a hot bulb get wet? I have and they shatter before the element sparks/burns out. All it would take is one drop of condensation and some combustible bilge fumes.
Good references DeltaT. I never said the things people do are right, or safe, and your post reinforces that.

I personally saw an Islander 36 explode about 400 feet from me once. Not a pretty sight as the entire deck & coach house blew clear off the boat.

Re: Extreme Cold

Hi wattage, low wattage, specialty, halogen, many types of filament bulbs are still available and being manufactured.

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.

Re: Extreme Cold

+1 on the heat tape being safe. I bought one not to long ago and it had a GFI on the plug.

Question on the Heat Tape:

How much heat can they take without burning up or becoming ruined.

I'm asking because I'm curious if heat tape can be wrapped around engine parts as well as through hulls.

Re: Extreme Cold

It can be used on engine piping, manufacture says up to 1-1/2" pipe. I would take that to mean with the low heat output, the heat will not penetrate very far. I would use armiflex insulation over heat tape wires and item being heated. http://www.emersonindustrial.com/en-...csheet_web.pdfhttps://www.youtube.com/watch?v=tZm1v12oJJM

"How much heat can they take without burning up or becoming ruined."
Sorry I do not understand this question? How much heat can what take?


Sorry, I was mistaken that the heat tape I purchased has a GFI plug. It does not, but the heat tape does need to be plugged into a grounded GFI circuit.

The heat tape... Can you wrap the heat tape around areas of the Engine that reach high temps.

Re: Extreme Cold

Engine parts can reach extremely high temperatures, well above 100C on the exhaust manifold, and heat tape is not designed for anything near that. You'd have to contact the individual manufacturer to find out how much heat any product can withstand, but I wouldn't pout them on anything that you couldn't lay your palm on.

Like the exhaust? And leave the heat tape on when running the engine? I would say it depends on the type of heat tape and if you can hold onto the item with your hand with the engine running, it will be fine.

Are you talking about your heat exchanger that froze on you? Yes, on that would work great!

100C is not a problem for heat tape. Heat tape, depending on the type, working temps. ranges from 150 to 450 F and the jacket will do twice that. This can be an issue with plastic pipes. My wet exhaust hose is rated for 250 F.
