Aluminum Downspout Hot Air Solar Collector Construction
Loading...
Uploaded by GScottVideos on Oct 25, 2010
Detailed descriptions of the construction of two aluminum downspout hot air solar collectors. The original was built by me, Scott Davis, and it works well, but then Scott Smith built bigger and added some really nice enhancements to collect a lot more solar heat! Scott is pulling 160F air from his down spout collector with lots of air flow and a better than 60% efficiency performance!

thanks for your awesome videos! I have started a project of installing old freezer box panels as skirting for my 14x70 mobile home that is located in direct sunlight. Just need to figure the best system to keep the craw space above freezing year round and hopefully use to heat the home and water.

I'd really like to see the costs and time to break even calculations for some of these projects.

@blurglide Hi, the hot air collector with a screen absorber may work as well or even better and is definitely a cheaper approach that the downspout. While more expensive, the downspout is nice because your air is completely contained in the downspouts, which among other things, makes it easier to seal Typical payback on a DIY hot air collector is about 2 years. Given these last for decades, in addition to the fun, it will pay you back many times over!

@blurglide Hi, typical break even on solar hot air collectors is 2-3 years. Given that they will last for decades, that is a fantastic return on investment!

Great video, Tried to go to your yahoo-simply solar but it doesn't exist. I tried a few times and triple checked spelling. Any suggestions please.

@mark16596 Hi, yes:
1. Go to the Yahoo Groups website (as usual, I can't post the link).
2. In the "Find a Group" text box, type SimplySolar (without a space). It is the first group that comes up.
