homemade heater for plastic waterer?

[chickenchalupa]

Here in wisconsin the weather can get well into the negatives and i need a water heater for my girls' plastic waterer. I'm hoping to make one for myself for pretty cheap. The waterer will be outside all the time. I need ideas, thanks!

I think if you use a waterer with heat you should use a metal one. I would be afraid that the plastic would leach chemicals into the water after being heated for so long. I won't reheat food in plastic anymore. Too many bad stories about chemicals especially from China.

There are heated waterers out there. I would buy one (I know money is tight) so you know it is safe and will work.

google heated waterers and see what you find. I have to put that on my list of thing to do for tomorrow.

I'm not ready for winter yet!

Most heaters dont really get very hot.
They only have to keep the water above 32 degrees
The simplest one is a light bulb in a box with the waterer on top.
A 40 watt bulb is about all it takes

You can buy a device called a "Thermocube" that will turn it on at 35 degrees and off at 45 degrees
