A simple solar heater that is cheap and easy to make. When there is direct sun on the unit it produces heat like a hair dryer.
According to the creator it produces a stream of air of around 120 degrees.
Some suggested tips for improvement:
– Make sure your black paint is matte so it doesn’t reflect the sun.
– The air moves by convection, however, you could add a small computer fan on the outlet and wire it to a 12 volt solar cell the unit to control the air rate.
– The intake size could be adjusted to control air rate as well. Making the intake smaller will give the air time to heat up while passing through the dryer ducting but it will slow down the rate of air flow. You can run it hot and slower or with more air and not as warm.
– A flat plate could be added between the intake tube and inside wall up to a little pulley inside the house. You could then adjust the air rate like this as well and have an on/off option.
– Add insulation to help maintain heat running through the system. Could prove vital for very cold areas.
Last year, my electric bill was over $ 600.00 Dec., Jan., Feb., and I live in Ohio
Wow
$600??? We pay that or more every month for our electric and gas bill. Thanks ConEd

looks simple and cheap. I would run the outlet pipe into house using a dry vent reversed and small hole with a piece of conduit coming in back on lower end. So, you don’t se any outside pipes.
Built one similar to this using tin cans. Works great!
I would tilt it out a bit on the bottom so that brick, metal or lava rocks could be put in the box for added thermal mass – a little extra heat after sundown. Then insulate and enclose the space created by the tilt.
Insulate your house and get a heat pump. My house is 2400 Square feet and has two heat pumps and light bill has never been over 180 bucks. That the cold months. I am getting me an outdoor boiler to beat that.
So your basically heating up carbon dioxide, and promoting bacterial growth. If some one is sick this is a great way to spread a virus. real heating units like the one in your ac push FRESH air into your house.
