We all have many old junk items lying around in our homes or garages. And we all wish we had time to get rid of them properly. I don’t know if you’ve noticed, but a feeling of liberation comes after shedding old stuff.

However, before you start throwing anything out, we want to show you an incredibly creative DIY project that may change your mind.

Make a solar heater with soda cans!

This DIY heater can make an average temperature difference of 20 degrees Celsius between the inlet and the outlet. But its effectiveness would, of course, depend on the size of your unit. The larger the surface area, the more solar heat it can get.

It’s not the one great solution for heating an entire house. It might be just a small measure but considering that you can make one out of ‘trash’ and excess materials you have from previous projects, it’s a project worth doing!

And along with other small and simple measures (like making your DIY insulated curtains), we’re confident they can all make a significant difference as a whole in keeping your home warm!
