Wire a snap disk controller for a solar air heater

Heating costs can be extreme in the winter, but a solar air heater could help keep the costs down. This video will show you how to wire a snap disk controller in a safe manner, to be used in a solar air heater or any other application. This is intended for people not familiar with electronics. Anyone who already knows how to do safe wiring may find it too simplified - though electronics enthusiasts might enjoy the journey.

For an example of a bimetal snap disc thermal sensor controller, check out the Electrical Temperature Control Circuit on rimstar.org. Also, see the Window Solar Air Heater (indoor to outdoor airflow) and Window Solar Air Heater (outdoor to indoor airflow).

What a load of rubbish . All he has done is spend 2 videos wasting your time on how to create an extension cord which plugs into the mains. It would be easier and cheaper to buy and extension cord and plug a fax in it that has a thermostat on it . Where is the solar part?

By the way... what you suggest wouldn't work. You'd still have to extract the thermostat from the fan and extend the wiring to put the thermostat inside top of the solar air heater chamber - and keep it all safe. Now you've got thinking of redoing these videos to be more suitable for people who know little or nothing about solar air heaters and are watching just out of general interest.

Done! I made a completely new Part 2 which shows it being installed and used in the solar air heater. Thanks Kim, for taking the time to make the change!

I made this video in response to someone who knew nothing about wiring whatsoever and wanted to know how to do it safely. So I had to start from absolute scratch. It was very well received in the SimplySolar yahoogroup, where the request came from, by the solar air heater makers there. The only debate was about safety issues. Also, the description above is wonderhowto's, not mine. They do tend to flower things up a bit. It is a little misleading i.e. might lead someone to think this is going to talk about the solar air heaters themselves and that the video might be hard to follow.

Actually, on re-reading the description they pretty much nailed it in the second sentence. I guess the first one is to get people's attention. I've asked that the third one be changed to better inform as to the intended audience.
