This is my version of a solar hot air panel that I built over the last two weeks. From little testing I have been able to do I believe this panel will produce substantial heat

MTD Solar Heating is a low cost method of harvesting the sun’s heat energy. It was designed for do it yourselfers.

Nice implementation & presentation. Thanks for sharing your creation!
I think using firebrick just behind the cans and covering the entire rear portion would tend to hold heat a while after the sun fades. What do you folks think?
Do you have a link to the fan set up that you used?
Is it better the have double pain glass or just a single glass. Or does plastic work better. I was thinking the double pain glass would hole the heat in better but does it take longer to heat up
good video but what the hell is going with the god persona in your voice?
could you tell me please how you made the ends of each of your boxes… they are rounded. how did you make them >?

The idea of using inside air for your intake is great, restaurants do this with there exhaust fans. Other wise it would cost a fortune to keep heating the cold air from outside. I plan on doing that with mine because no matter how good it works when it get to be -20 outside it will not work nearly as well as taking air from the basement that is 80 degrees warmer then outside. Thanks for sharing.
@baggetja1234 YES!
Use Silver Tape (Nashua) for AC/Heating – you can buy it @ HDepot cheap. Its heat resistant and glu holds like crazy. BUT:
You DONT have to use cans – it’s ok to buy/make 2″or3″ COOPER tube/pipe and put a turbulator inside (turbulator twisted like screw piece of tnin metal like alluminium – often used in water boilers) .
@shoestring405 There is a youtube site that is really good. He has done a lot of testing with different designs and the information is great. Site name: richallenmusic
@shoestring405 I was planning on putting cans inside the downspouts for more mass and using old aluminum highway signs painted black under the downspouts. The sighs are 1/8 thick aluminum and I have 4 of them.
@shoestring405 Thanks for the information. I just replaced two sliding glass doors and now have 4 dual glass sealed glazing panels for the project. I plan on building two collectors. Thanks again!
@shoestring405 Thanks!
@baggetja1234 I used hi temp gasket maker, the stuff they use for putting car engines together
@jamoore3192 the panel is completely automatic. you install a disc switch ( fan control switch ) inside the panel on the hot air end. The switch should open at 90° F and close at 115 or 120 F
the panel needs direct sunlight in order to produce heat, Here in Nova Scotia the panel works best on those cold clear days in January and February.
@4153promos I would be careful using a fresnel lens. I have seen experiments where they have etched
steel using a fresnel lens and sunlight
@navajopa31 amount of air coming in contact with the heated surface.
3. It will be necessary to install a few baffles of some type in each downspout to mix the air.
This will also help reduce the effect number 2.
@donsjuand Thank you Don. Check out the latest improvements on the MTD concept.
@kathrynjustice05 No it does not work that way. Look up the latest improvements on MTD.. just google MTD collector kit
@dieseltwitch Not really.. This is what the Mylar inner film is for. I only lose a few gallons a year for a 200 gallon system on the new design.
Looks like what you save in heating you will end up spending in water lost to evap
@doggiesarus nice acc name!!!
Would Aluminum coated Mylar (the reflective type like an emergency blanket only 4 Mil thick) produce more heat instead of the felt?? I have about 300′ x 54″ and thought since it reflects up to 99% light including much of the infrared spectrum, it may work better??? Thoughts or have you tried this?
It’s funny how the tie-die shirt exemplifies the treehugger hippie stereotype! But I love the concept of what you are doing and think it’s great you are doing a good thing by posting help for those interested in lowering our fossil fuel footprint. A+!
can you explain this better i cant see how it works
John I am a poor man and cannot afford your kit. Can you share where to purchase the felt you use?/I have made a bulk tank from a recycled hotwater tank from the dump, I have a 100 ft coil.blk pipe on the roof , trying thermosyphoning however I may need a solar pump to circulate the water..any help Thanks Phil R
Although MTD systems are more portable than most solar applications. Collectors, heat storage tanks and heat distribution systems are not meant to be moved. Solar energy is a long term investment and way of life.
