DIY Solar Powered Furnace - Diy Solar Generator

DIY Solar Powered Furnace

I paid more than $400 last year to heat my house during the winter. I could've easily built this solar powered furnace and saved that money. Generating solar power is free... why not take advantage of it!

You can probably find most of the materials needed for this solar powered furnace at your local dump or scrap yard. Anything you can't find can be bought for less than $50.

Here’s What You’ll Need:

  • A 3ft x 5ft piece of black plastic
  • 2 - thin glass windows with aluminum frames
  • 1/2" lag bolts
  • Lumber
  • Angled ABS plastic joints
  • Cinder blocks
  • PVC pipe
  • Scrap piece of insulation
  • Scrap garden hose
  • Dryer hose
  • Black spray paint
  • A 2×6 board
  • A Hand drill

Step By Step Instructions

Step 1: Build the frame by assembling the lumber using the lag bolts.

Step 3: If your glass windows fit the wood frame properly, remove them and attach the black plastic to the back side of the frame.

Step 4: Now, stand the frame up and level it to match the same height as your window outside of your house using cinder blocks.

Step 6: Feed the PVC pipe from the furnace into your window, like an exhaust.

Step 7: Fit the dryer hose inside the frame like a coil, so it fills up the whole space inside. Use fishing line and staples to carefully attach the hose to the frame.

Step 8: Spray a light coat of black spray paint onto the dryer hose.

Step 9: Install the window panes on the front on the unit.

Step 10: Drill holes into the 2x6 one for the larger exhaust and two smaller ones for the intake. Wrap the exhaust with the scrap piece of insulation to avoid losing any heat.

So, here's how this works... the intake hoses draw air out of the house while pushing warm air into the house through the exhaust.

During the winter months the solar rays hit the box, heat up the cooler air and then push that heated air back into the house. This is the perfect little DIY solar powered furnace.
