Passive Solar Air Heater Heating System Alternative Energy
This is a video of the Passive Solar Heating System in use at www.envirosponsible.com in Whitby, Ontario, Canada. It provides a great deal of heat, and the installer, Chris, will be making it more effecient by adding a second computer fan to push the warm air at the top, painting the inside better and taping the duct work. Also, the duct work will be directed into the office where the door can be closed and used in a smaller air mass. Visit our site at envirosponsible.com or call us at 905 …

That’s a great idea.

Cool! Or should I say Hot!

Hi
That’s a nice demonstration solar heater/collector but you don’t get more heat in the store than you would with the clear window.
Search ‘direct Gain’
Keep up the good work and best of luck with your store.

Hey solarevolation, thanks for the comment.
I didn’t think we were beating the laws of thermodynamics. The main idea of this setup is to divert that heat into the office where there are no windows and where we can close the door.
Ideally, I would dedicate a large portion of the southfacing wall to enclosed passive solar panels, leaving the windows for the view, light and direct gain.

You WOULD get the same gain from just a window… if everything inside the bldg. were painted black!

I think we might disagree on other things as well (peak oil?).
Does a car with black seat covers get hotter inside than one with white seat covers? I will test that.
I do know a black car does get hotter inside than a white one.
I do, however, love your farm and respect your can do approach to “The Problems” we face.
—————————————-
Paint it black (or actually Popular Science had a cover article saying elm green is better) if you have a thermal mass inside.

electrovideodude,
Appreciate Your comment on MY videos (btw, no farm, just 1 acre)
Maybe one of us could paint a pop can black, another white, and place both inside mason jars at the same time… testing air temps over time. Hmmmm interesting.
Sometime; I intend to do a vid explaining my theory that oil does not actually have to peak… to adversly affect economy regardless of current prices. Also why oil production problems (really) are the hidden cause of the current economic crisis.

That diverting is still a good idea… especially if the space with the windows gets too hot; use the heat somewhere else.
Department stores could supplement heat that way. They have window displays that are like a little room with a big window.

I would say for efficiency the heat output should be at foot level as it will rise. Correct? Other wise you need a fan to circulate the warm air downward,but that would make the system Non-passive.

do it make you wonder why there is still so many lazy bozos still relying on dirty firewood for home heating??
April 1st, 2009 at 9:17 pm
Oh yeah. When the general public realizes they’ve been robbed on the largest purchase of their lives-their houses, they’re gonna be furious. Developers, builders and government have allowed the greatest misalocation of resources in human history-the suburbs. We’re going to have to overhaul our lifestyles and our houses. It’s mind-boggling.

I built a 4×8 can heater like the ones they show on utube I put in a bath fan and a shut off switch on the wall used 1/4 inch glass the first day the sun shinned all day I turnned my temp down it was 65 in the house outside it was 39 I then turnned it on the temp stayed 72 all day in the house for the past two days the temp has been to hot so I had to shut it off. Im happier than a pig in the slop.

I think we’d all like to see your system on YouTube. How about it?
April 21st, 2009 at 4:15 am
a few more comments about my system I dont have a way to put the picture on here so I cant . I I used heavy material which was a mistake 2×8 and 1×2 in plywood and 2 inch hard and alumium flashing inside and somewhere close to 300 cans washed. and painted with a high heat paint. I should have used 1×6 and not 2×8 and 1inch insulation and not 2in. to save money I found the local second hand construction store and bought the 4×8 slider for 10 dollars.
April 21st, 2009 at 4:22 am
I bought the slider for 10 dollars I then took the alum that is around it off and seperated the two pieces of glass 1/4 inch glass and used only one I am now building another one to use in my house this winter. I am using 1×6x6 pine this time my heating bill in the winter has been 330 dollars a month.

Hi
Looks Great – Im going to have a go – Is your window double glazed ? I have lots of aliminium surrounded single windows Ive been saving – Would the work

Yea Alt E is a great place. I got a solar oven there.
I’ve been constructing my own heater with a fresnel lens on some rocks.
May 16th, 2009 at 1:02 am
There are several Can heaters, Which one did you mimic??
With my last heating bill off the charts, I’m going to have a solar alternative this Winter. Do you have any temperature examples, ( in fahrenheit please ) 32C means little to some of us.
Good job

so how much heat can u produce in the winter time with a bright sun? how many would u need to warm a 15×15 room to 60 degrees.
