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:
Over one thousand comments.
HOT TOPIC! Pun intended.
Is it legal to be self sufficient in America?
One of these in your home might get you a fine and jail time.
I understand people all over this country are being raided by the grid cops for going grid free.
Ok, now show me how to keep cool when the ambient outdoor temp in the shade is in the triple digits and the winds are calm?
Would this work in a small greenhouse for winter months?
Even easier in a greenhouse. No box needed. Jus stack cans and paint flat black. Put in sunny location. DONE!
I’ve already got a good start on the cans.
The fan is solar powered?
Could you keep your sidewalks clear from snow with this?
Can I suggest a rubber or foam air block around cans at top and bottom. Then you only need one or two holes at the bottom as the cold air would be forced to flow through the cans. And the hot air would be collected at the top.
So can a human touch!
A friend in Minnesota built one on a 4X8 ft and it was painted black and at 40 below zero it put out 90 degree air into the house
