I like this style of solar air heater because the air heated does not come in contact with potentially offgassing black paint. I'm building one this morn & my main prob is the double glazed 6'6"x38" window is so heavy, the 2x6 adds weight as well, but I'll try it anyway.@ least I use the glass! Wanted it to be a bit more port, but maybe next one- Metalstuds,plasticglazing..I may compress the duct and maybe add alum as well. Metal tape is our friend! Nice work& thanx for posting & inspiring!!!
My isnt connected to my duct it simply pulls cold air off the basement floor which feeds thru the solar heat collecter and is fed back into the basement ceiling which inturn warms my livingroom floor
We built one similar for use in Duluth, MN. We did not use a blower and fed directly into our air exchanger. Our heating bills were only $500-$600 a year because of how much heat we got from our panel. The questions I have about your panel are: How and where did you connect in to your furnace ducting? The distance to the furnace from the entry point to the house? How do you close it off in the summer to ensure you are not allowing heat into the ductwork in the summer?
Yes it has 3/4 R-board lined in the entire unit,I painted it black for more sun absorbtion ,I figured there wasnt enough rear surface area to reflect due to the piping laid against the r-board,Thats why I didnt bother making the back r-board reflective.
I did not see if you added any insulation to the sides and back of your box, I would think that if you insulated this well, as well was able to put in some water holding tanks to absorb heat that you could still have heat produced even after the sun has set for a few hours.
Too bad you couldnt put the box in a vacuum so it would be perfectly insulated! I would like to see the temps you would get with it that way. I might have to make mine under a vacuum if its even possible.
It needs a bigger fan to keep temperatures down. The higher the temp in the box, the more heat is lost to outside. Higher volume of air at lower temp still gets the same amount of heat into the house. Watts = CFM * (F out - F in) / 3.0
Also, the ducting needs to cover the full surface area for better heat transfer. Otherwise this design is just as good as the aluminum can method. Metal gutters are good size and cheaper. Just make sure air flow over the black surface is at least 7 fps.
The speed of the PC fan was just about right,The one thing I would do different is to power the fan with a solar panel,that way the fan would also be controlled by the sun.
your idea looks the easiest ..so far ...I have a blast watching these videos :) ...and your music was just fine... thanks for passing on your idea ...
Hi, I just wanted to know why you've painted the back panel black instead of letting it reflective, it would have reflected the heat more on the black tubing, thus giving more heat to your air...just wondering
cold air input temps were approx 50 degrees F coming off of the basement floor,Output temps vary on outside temps and time of day,at peak sun temps returning to my basement at ceiling hieght were around 85-95 F,I have seen temps inside the housing as high as 180 degrees,so at housing temps at 180F the cool air intake was approx 50 F the warm air exhaust temps have been as high as 95 F,Air speed thru the duct also has alot to do with output temps
yes thats exactly what I did,Worked like a cold air return that was drawing the air from the inside ,then circulated thru the heater and back into the house,I used a 12 volt pc fan to move the air
Nice job! I'm wondering if it would be best to recirculate the air from inside the building your trying to heat, or bring it in from outside? Seems it would be easier to heat if you recirculate the air, like a heat pump?
Hello I'm doing a project in my Engineering Graphics class. Wanted to let you know that I'm posting your video in my blog and using it as research for part of our ideation phase. We're creating a solar powered heater and looking for the most efficient and affordable way to accomplish this task. Yours looks awesome and you have some really great ideas!
Just a suggestion here, it would have been nice to see some temp gages. Showing what your getting out of the unit. Perhaps give some details on the money you saved. What it costed to make.
Consider using aluminum gutter drain pipes...$8/each for 10ft lengths at home depot...building mine now. Aluminum and Copper are the best metals for conducting heat.
i have one problem with this type of design very hot air heating' insulation plastic materials' and then blowing that contaminated air into your home. i think it could be a health hazard.
@mesmerizeme look closer! The air never touches the insulated cavity! The insulated cavity heats up causing the heat to travel through the pipe and heat the house air. Similar to a heat exchanger in a furnace. your furnace doesnt fill your house with exhaust gasses does it? only the heat goes through the pipe, not contaminated air!
Can you test your heater with CO2 gas inside the box and post the results, but CO2 should not leak with room air. Because Co2 increase the temperature.
at least it wouldn't be heating up the rest of the world.
look people no one has a problem cleaning the enviroment but telling us we are going to fry over co2 is a scam. look it up people quit believing non science based BS. i am how ever. rather loving all the idea's that are coming out of this to screw an electric company out of huge profits.
if a person wants to make a video to help or show other people how he or she made it then the music if that what its called should be replaced with a person talking and explaining what was done thanks for the video anyway
I think the stainless steel duct is much easier than stacking and glueing pop cans together,aluminium duct may be more conductive than stainless though.Just my thoughts!!!!!
Do they have aluminum flex ducts on the market in lieu of what you used here. I understand the reasoning behind making this a baffle design: time under temperature increases efficiency.
@lawnngardenguy You just have to search thermal conductivity on the net. Aluminum is better than stainless...different gauges of plexi have different ratings though. Glass seems to conduct heat less than plexi. Copper is better than aluminum and after that comes nickel, gold...blah blah blah. Good idea though. Use 3 inch instead though...more surface area...and change it to aluminum flex duct.. You'll see the difference.
Sorry bout the small text,Yes I use this to pump hot air into my basement using a fan to suck the hot air in,my livingroom is located directly above with hardwood flooring ,So I figured it would assit in heating the floor.
input temps were approx 55 degrees F coming out of the basement,Output temps vary on outside temps and time of day,at peak sun temps returning to my basement were around 85-90 F,
How about some stats. The materials for this could be really cheap and it looks like it could be productive.
Have any air inlet and outlet temps? how about type of fan used, if it actually heats the room, room temps to outside temps. Inquiring minds want ( need ) to know.

A Solar Heater requires a bit of sun to heat it. WHY build it? Surely it would be warm inside the house also. Build a snow cooler for the winter.
