The Heat is FREE - DIY Solar Air Heaters

As winter sets in we all start to think about the cost of heating our homes. 

Capturing and managing the heat from the sun - called 'passive solar heating' - is one the most inexpensive and sustainable ways to reduce your carbon footprint and heating bills. 

Solar air heaters - sometimes called 'pop can heaters' are a great DIY project. There are hundreds of design ideas, how-to videos and articles online to get you started.

If a portion of your home gets direct sunshine on it for several hours during the day, why not make the most of it and capture all that free heat.

Solar air heaters collect cool air at the bottom. The air is warmed by the sun as it rises and exits at the top.
