The warm summer months never last forever. Soon it’s time to look for a way to bring a little extra warmth into the home and this simple solar heater is a great project to do just that. It’s made of metal cans, steel or aluminum, and can produce a surprisingly strong and consistent airflow upwards of 140F.
Even on a heavy snow day you’re looking at somewhere around 75-85F.
Best of all, this simple project requires just a few common parts and many of them can simply be re-purposed from your regular recycling. Watch the project come together in the fully-detailed video on the NEXT PAGE:
Metal gutter downspouts painted flat black also work well.
William Fulton, weird but…… Van, camper, tent.
Love this idea but wish he would have covered the part on installing the solar panel.
needs more insulation
made with roofing metal painted black, and old storm windows.
Larry Swackhammer I want to try this can thing!

“Could you somehow place this unit in a south facing window, inside, and have the hose simply on the floor?? No need to have unit outside then. Curious as I’d like hubby to make one but don’t want it out in -29* snowbank.”

Back in the 70’s my Dad made one out of black painted cans nailed to plywood. He created a triangle box filled with river rock and an opening between the two for air flow with little fans on top to circulate the heated air, and the rock held the hot air for distrubution through out the day.
