[zuludog]

Just had another idea There are heaters for aquariums (aquaria?). Most are submersible, some are pads so you place the aquarium on it

'fraid you'll have to do some more Surfing!

had a heat lamp for reptiles that would be hot enough, any pet store should have it.

Looking at my bottle of Fiebing's Edge Kote, it says right there do not freeze! The rest of your items are correct.

I can confirm the light bulb thing, they are often used here in poultry farming for heating.

Old type light bulb emit about 3% of energy into light, the rest is heat, for example 100W light bulb is actuality a 97W heater that happens to give out light, 200W light bulb is a 188W heater and so on. Just get a bulb socket on a cable and place it in a well isolated storage space, as small as possible to avoid heat loss. Be careful not to place the bulb too close to plastic, it can melt it if too close. The problem is these light bulbs are getting very hard to find.

Another alternative is infrared light bulbs, also known as heating light bulbs, that are specifically made for heating.
