Home Made Solar Air Heater/finished

Is your panel big enough??
A little computer fan shouldn't require very much juice.

how cold of weather does this work in?

hi i am making one of these but i cant get my fan to run off my solar panel i am told that i need to use a 12v battery but i don't see you using one can you help please
thanks

I think the way forward is definitely in projects like this one. Giving money to the big energy companies to "invest" in renewable energy is a joke at our expense, don't give them a penny, try to do something for yourself. We must pool ideas together and sod the governments.

have you used one of these during the winter months ? I'd expect this to work in 22c weather but how about -10c winters (which I see every year where I live) ?

lovely work. i sent you an email.

humbertini900, How did you decide on a 22mm pipe? I've seen others that have a much larger pipe.
Maybe that's why your works so much better? Also do you know how many CFM (cubic feet per minute) the fans blows or what size it is? Diameter of fan. Is it a Computer type fan? CFM is what we Yanks use. Not sure what you use, Meters Cubed per Minute?
Anyway it sure is Fantastic Mate! Are you going to heat up water next?

thank you rasoros, and you are correct there is no water involved in this set up just air getting warmed by the cans that absorb the heat from the sun, it's really effective.

I will answer for the creator of the video..

no, the cans are not filled with water. That wouldn't make much sense, think about it.

ahhh, so this isn't a closed circuit unit? So you're pulling in cold air from the outside and warming it through the cans, correct?

I've been thinking of building one but having the input pipe draw air from the bottom of my garage (which is already warmed).. and that would be far more efficient.

that said, you've done a nice job on that unit.

Does the air flow over the cans and heat or does the air flow through the inside of the cans....and if that's the case did you cut the tops and bottoms off to make a continuous channel for the air...Is there just one outlet or is there an inlet too?

guys the tube into the house is already insulated, just when the video was donne I had just finished installing it.
cheers

really cool, u should insulate the pipe that goes into your house though. :D

Simple yet brilliant. This is a perfect project to introduce people to solar energy. I will have mine built as soon as i can and post the video. I have everything i need in my shed except the tubing. Sir, Honors to you.

Is there a fan, or is it all convection currents?

Maybe I'm dull, but what's the solar panel for?

Perhaps you should heve tube leading the heat in go immediately to the inside, by drilling through the frame of the window. On a cold day, your warm air (already less than 47 degrees on a cold day) will be cooled off by going through this uninsulated tube outside the house.

Good job though, I hope it hleps out with the heat!
