The solar heater actually works very well. Air gets pulled in through the bottom and circulated through the black aluminum cans and exits as hot air. It works just like it’s supposed to.
The problem I have is that attaching it to the house has proved more difficult than I thought. The area I originally planned to put it doesn’t get quite as much sunlight as I thought. Unfortunately, the house is made of concrete, so attaching it to the house and adding holes is very difficult. I am currently looking at mounting it in a different location and using long pipes to run it into the house.
Until then, here are some of the pictures from the building process.
