During winter, heaters are a must to live comfortably in our homes.

You’ll need these materials:

  • 3′ x 5′ Black Plastic
  • 2 Glass Window Panes with Aluminum Frame
  • 1/2″ Lag Bolts
  • 2″ x 6″ Timber Frame
  • ABS Plastic Pipe
  • Dryer Vent Hose
  • Black Spray Paint

And these tools:

  • Measuring Tape
  • Drill
  • Table Saw
  • Staple Gun


Gather all the materials listed above. Start with your 2×6-inch frame timbers. You can join the timbers together by using the 1/2-inch lag bolts. If you’re using pressure-treated lumber, be sure to use galvanized bolts and washers to avoid staining the lumber.

Cover one side with the 3×5-inch black plastic. Then set the glass window panes with an aluminium frame on one side of the frame. Make sure things are lined up well before finalizing and mounting them with lag bolts.

On the top part of the frame, drill a hole that will fit the ABS Plastic. This will serve as the output vent of your solar furnace. Make sure the hole is big enough so that the heat can escape, but not so big that it compromises the structure of the furnace.

The diameter of your plastic ABS should be the same size as your dryer vent hose. These should be angle screws right on top of the unit. Then cut a piece of the pipe through the window.

Next, take your dryer vent hose and insert it into the frame you created earlier. Be careful not to damage the hose as you do this. Secure the hose in place using a fishing line and staples. Make sure the hose is taut and fills the entire space before proceeding. To help absorb the heat from the sun, lightly spray the aluminum frame with black spray paint.

Remember to connect the intake for the solar furnace to the bottom of the house in order to draw air out. This is an important step in ensuring that the furnace works properly and that your home is heated efficiently.
