It may be the most wonderful time of the year, but it sure is cold. In some places, it’s so cold that an extended power outage could be deadly. Hopefully, you’ve prepared your home for winter and have several ways to heat your home without power, but there is one way to heat your home that doesn’t require any fuel or firewood: a solar furnace.
A solar furnace could keep a single room nice and warm on a sunny day. This would be great if the power went out as you wouldn’t have to use any of your fuel. Just be sure to put it on the south side of your house.

- Build the frame using all the 3 and 5-foot pieces of lumber.
- Attach the sheet of black plastic to one side of the frame.
- Cut a hole in one end of the frame large enough for the pipe.
- Connect the pipes from the end of the frame into a nearby window.
- Attach the dryer hose to the other side of the hole and have it wind back and forth so it all fits inside the frame.
- Spray paint the dryer hose black.
- Attach the window panes.
- Cut holes in the fifth piece of lumber. One hole is for the exhaust pipe coming from the heater. The other hole is for the intake to draw air out of the house.
- Shut window against that piece of lumber and put the exhaust and intake pipes in place.
