Free Heat from sunlight is not a bad deal. When you use materials from your local home improvement store, the costs for building a window heater are very reasonable. When you use items from your backyard shed or garage, free heat can be even cheaper to make.
Solar heaters are popping up everywhere on the internet, with several designs using aluminum soda or beer cans as the mechanism to absorb the sun’s light and transfer it into hot air. This is a fairly simple process that happens everywhere the sun shines. If you have ever stood in the sun on a cold day, you notice the light coming down actually makes you warmer than if you were standing under cover. In addition, if you happen to be wearing black, you’ll notice the sun will actually make you feel warmer faster. This is the process that you can take advantage of and apply it to generate heat for your home or other enclosed space.
Building a cheap solar heater is pretty easy to do for getting some free heat to be piped into your greenhouse, hen house or even your own house. I made my first unit from recycled materials I had in my shed and garage and within an hour created a simple design that cost me about 3 bucks out of pocket.
