I wrote several posts last week on how to reduce your heating bills this winter, in which I promised you all a tutorial on how to make your own solar heaters. You can see that post series HERE, HERE and HERE.
We’ve made these solar heaters and are currently using them. The rooms that have them stay significantly warmer than the other rooms in the house. I’d say they are warmer anywhere from 2-5 degrees. That’s a significant difference that can definitely affect your heating bills this year.
Materials you will need:
Hot Glue and Hot Glue Gun
Spray Adhesive Glue
Black Spray Paint
Plastic Film (pick up at your local home improvement or supercenter store)
Pennies (or something else that is copper)
Here are the schematics and steps to make this:
Step one: Cut out all of your pieces from the foam board.
Step Two: Spray adhesive glue on the center cut board, and place your pennies or other copper material on there. We measured out and drew graph lines so that we could put all the pennies on evenly.
Step three: Spray Paint Black.
Step Four: Cut slots in the top and bottom pieces (the trapezoid ones) so that your heater can breath. The top slot needs to be bigger than the bottom slot (see picture below).
Step Five: Use hot glue and place the edges together like in the schematics picture. Be sure you seal all the edges with the hot glue. Let dry.
Step Six: Put winterizing shrink wrap (plastic film) over the concave opening and use packing tape to reinforce the wrap. Be sure not to cover your open slots in the top and bottom. Blow with a hair dryer to tighten the plastic film.
And there you have it. Place in your window to naturally heat up your room.
Final cost for three of these was: $30
