STEP 4
The fourth and final step is what will enable your solar heater to transfer heat more effectively into your home. Like any good space heater or window unit, it’s got to have a fan to direct the heat.
You’ll need at least three miniature solar fans. You can find these available online in several places, Amazon being one.
The fans designed to clip onto the bill of a ball cap are the easiest to install and work with for this design.
Once installed, these fans will be used to push the hot air from the inside of the solar heater to the room you’re trying to heat up.
