One of my dogs cannot be trusted inside while we're away, so add that to the fact that we have no garage or shed, and you can see why I had to come up with something. In this instructable I'll show you how to heat a dog house with a 100 Watt flood light, a paint can, an extension cord, a lamp base, and a few other items you may already have. The current set-up seems to keep an interior temp. of about 60 deg. F. in weather slightly below freezing.
Warning: There is a slight risk of electrical fire if you do this wrong, so be careful and keep an eye on your completed, heated dog house for the first few hours it is in use.
Step 1: Here's What You'll Need
1. A gallon sized paint can clean of all flammable substances or a tin can of equal or larger size.
2. A 100 watt outdoor flood light. Colored bulbs are recommended as they put off equal heat, but less light. In colder climates a ceramic heat bulb might be a good idea, they put off more heat and no light, but proceed with caution as I haven't tested one with this equipment yet. Here's some links so you know what I'm talking about.
What I used:
Ceramic heat lamp:
3. One ceramic lamp base without a switch
4. 1-Gang Metal Ceiling Electrical Box, the kind that's roughly a 1/2 inch thick
5. A wire clamp to secure the wires to the box
6. An outdoor heavy duty extension cord.
7. A drill
8. Hole saw equal or slightly larger than the hole in the electrical box
9. A set of drill bits.
10. A jigsaw
11. Small corner brackets.
12. Screws and nuts the correct size to fit your electrical box and corner brackets.
13. 1/2 inch long wood screws
14. Tarps or old dog food bags made of the same material (optional)
15. insulation capable of withstanding the heat of the light fixture. Radiant barrier car windshield sun screen will do. (optional)
