I have a problem and that is that it is winter in New Zealand and because it gets so cold the monthly power bill can be very expensive. Up to $500.00 sometimes.
This started me thinking about the sun and the heat it makes, so I started looking.
It had to be cheep or free. When I saw OhMikes instructable it inspiried me to try my own

I used old fly screens I had lying around and in place of his foil, I re-used aluminium plates from the printing company I work at.
I painted one joined plate gloss black to absorb the suns heat and another plate for the back pannel.

I got it up and running and found it did not have enough air transferring through it so I added a solar panel I just happened to have been given about 10 years ago and a cooling fan from an old photocopier. 

The only new thing I had to get which also cost nothing was a meter of shrink wrap which was left on the end of a roll in the packaging dept at work.

It is now heating my kids bedroom in the day time very well and is creating a good flow of warm dry air.

My power bill is now down to $250.00 per month so I think the problem is solved for me and my family.

Thanks OhMike.

Step 1:

I assembled the heater using my own materials. I think everything is different to the instructable that inspired this.
This is a shot of it outside leaning on the Geodesic dome I made today.
<p>Pretty cool man! Another in-window mount solar heater like mine! I like how you used a solar panel to push the fan - i just wired mine to the electrical system of my home :( Here is my setup if u r interested:<br>https://diybarrelstoveoutdoorfurnace.wordpress.com/2014/12/28/diy-window-mount-solar-air-heater-presentation/</p>
