Heat lamps for temporary freeze protection

I'm out of town on business this week, so can't winterize until late Friday when temperatures are forecast to get into the 20s. I probably won't get everything finished in time, so may resort to placing drop lights in key places for the night. My only problem is that old-fashioned incandescent lights are now impossible to find in the US.

Do any of you have experience with alternatives? IR heat lamp bulbs? (Do they get too hot?) Ceramic heaters with bulb sockets, commonly sold for reptile pets? (Do they radiate the heat to another body effectively?) Others? What is safest and most effective? What fits in a drop light? I'm also willing to buy a different fixture to facilitate use of the bulb.

I've done some searching on Amazon (and need to order today to get it in time) but could use some help in sorting through the options.

FYI, heating pads are probably not an option, because the modern ones seem to all automatically shut off after 20-30 minutes.

I'd love to hear from someone who had dealt with this issue in recent years.

I’m not a fan of leaving a heater or lights on when not present. Especially a bulb designed to heat which means larger resistance.

Looking at the forecast it’s is going to get cold, yes, but only one night below freezing. It shouldn’t mess up your water systems. This is an early than usual cold system. Normal highs are 60.

Re: Heat lamps for temporary freeze protection

A heat lamp of many used to keep a new construction warm overnight for the employees set that mega yacht and 2 others beside it ablaze and smoke damage to a couple others, including mine, set construction back several months. For my 2 cents, if you could find a reliable person to do the winterizing , it might be a better option.

Re: Heat lamps for temporary freeze protection

The boat is at a DIY boat club. There are no reliable contractors in the area. Every time I've inquired about hiring someone, people invariably recommend their "buddy" whom I could tell from the booze on their breath that I wanted nowhere near my boat. There is absolutely nobody in the are that I would trust on my boat while I am out of town.

I'll get everything done that I can Friday night, but a couple drop lights for ~8 hours are a last resort fallback, and commonly used by my two next-door neighbors in past years. Leaving a 60w light turned on in a dry area is a risk that we all take daily in our homes and in every other aspect of our lives. I'll ditch the heat lamp, but I need to find a couple traditional incandescent bulbs.

These generate a lot of heat, and when the bulb fails, the whole thing is contained. Maybe one or two of these and a small fan to circulate the air.

Really? Home Depot lists 185 different old fashioned incandescent bulbs. As do Lowes. And Ace Hardware. Maybe they
have one of those stores in Pennsylvania?

Re: Heat lamps for temporary freeze protection

Why not just pick up a couple of small ceramic space heaters? They are perfectly safe to use and produce far better heat than a light bulb. A 60w or 100w bulb won't do much.

Re: Heat lamps for temporary freeze protection

Next 4 nights are forecast below freezing, but it looks like the upper air dip that is bringing the lower temperatures will swing past and be replaced with warmer air in the second half of November.

There may still be some time to winterize before the persistent cold of January-February builds.

For working on the boat when it is cold I use an oil filled radiator. I have not left it on overnight but no part gets hot enough for ignition.

Have you actually walked into a store and looked? I went to HD and Lowes yesterday. Everything is LED. Posted wattages are “equivalent” values.
