Solar Thermal Heat panel 210 degrees of free heat!

[@warlord8954]

Next time insulate the back and sides with foam board insulation then some foil faced foam board. Spray the interior black before installing downspout pipes, then seal it. Use a smaller fan. Like a PC fan at the bottom and the top. Higher heat production and more efficient air flow. Also, you can get a small solar panel to directly power the fans. That's real savings.

Increase air flow limit temperature gain to about 80 degree f. Highest home heating efficiency is obtained this way. You reradiate to much heat from the collector. Stripping the heat from the collector quickly means more heat in the home. Nice build and video.

[@keithreynolds7740]

More air flow may lower the exhaust temperature, but it is thermally more efficient at capturing solar energy as it heats more air. High temperatures with slower moving air are neat, but you loose more energy to the outside air through radiation and convention loses that essentially increase exponentially as temperatures increase above ambient.

[@openairrpastraining4756]

We are presently testing various metals and materials in similar designs, but our location is Canada, so variables in outside input air temps vary greatly on end results. Our design idea is to take consistent indoor air flowing through. Your video shows outside air, but at what temperature? That will change you results. Would be interesting to see a string of various air temps going in with a data list of resulting outlet temperatures with your system.

[@Comicsluvr]

I've seen several of these from colder climates (in the 40-50 degree range) that will put out quite a bit of heat. However, I would want to use larger tubes for better air flow and a diverter to not overheat the house in the summer. Cool step by step though.

[@phugwad]

I've been working in solar thermal, and related thermodynamics and heat transfer since engineering school (1980). Though one can build very simple solar thermal collectors with Home Depot materials, they won't perform nearly as well as a well designed and properly fabricated one. Though the data presented in the video doesn't really give us much of an idea of the performance of the collector (we don't know the outside air temperature, the solar insolation level, the sun angle vs the collector orientation, or the air flow rate, so we have no idea of how much energy is actually being collected) we can very roughly guess that the max temperature differential for this collector (the maximum difference between the collector temp and outside air temp, where heat production is zero) is about 90degrees F or about 50 C. A decent commercial flat plate collector, made with proper materials (able to withstand maximum temps, years of UV light exposure, selective emissivity coating on absorber etc) will reach 100 Celsius over ambient at zero output. In the case of this video we would expect to see a max temp of 330F not 210F. While a max temp of 210 may seem impressive and useful you need to keep in mind that this was only 90f hotter than the outside temp. Consider what would happen on a zero degree day in winter, where you need a minimum of about 90f temp above ambient to provide useful heat to the home. (you can't heat your home with air that is at the same temperature as inside the home, it must be somewhat hotter, which is why the air coming out of your heating ducts is substantially warmer than your home). The system presented would provide roughly zero heat on a zero degree day, at solar noon, if it was properly oriented at latitude +15 from horizontal. If the orientation was less than this, or there was any clouds or haze, or if it was earlier or later than noon, the collector would actually pull heat out of the house. A good quality, properly insulated collector, with a selective emissivity coated absorber and low iron glass cover (better still double glazed with a layer of fep inside) would provide significant heat on a 0f day, in winter sun, even with some haze.

[@jaredcox1195]

+strato man yeah, but it only cost him 150 bucks... I've watched a lot of videos on these... and although they might not perform as well as a commercial unit... they perform pretty damn well and can be a pretty good and cheap way of adding heat to your home... especially if you use recycled materials and a cheap temp controller device to cut the fan on and off. I live in the south... and our average low is only 32 degrees.... For a small well insulated home like mine this type of thing could be a great DIY supplemental tie in to my central air.

[@phugwad]

+Jared Cox You can purchase a decent selective coated, low iron glass, 2 sq meter panel from China for about $120. Such a panel will be rated to take water or propylene glycol at 8bar 120psi, and will heat that liquid to 90c over ambient and will last a couple of decades.

[@jaredcox1195]

Well, that's true.. but that would require a water heat tank, heat exchanger, pressure relief tank, pump, lot's of piping, valves, and expensive controllers vs a 10 dollar one I could use for this system. I could take this type of system and pull air from my central air return in the winter... blow it through a solar air heater like this using a cheap low watt fan (using recycled materials) and feed my central air duct on the other side of the heating element to deliver heat to my small home... if it didn't provide enough heat the existing HVAC system would supplement it. And it would last decades as well as long as the box was built out of good material and sealed well.

[@jaredcox1195]

you do seem to have a good bit of knowledge in the area... so i am interested in hearing what your best cheapest solution is for solar heating air and water for your home.. that also integrates with an existing normal unit (HVAC or typical hot water heater)

I would seriously consider looking at different materials that downspout material has got to be expensive. Great idea though I wouldn't have thought you would have gotten that kind of temp. Off of a unit like that.

[@bodryn]

I'm just guessing but I suspect from your year round temperature average, you could probably tap decent heat from underground. (heat pump) You should inquire locally about heat pumps and see what percentage of heating fuel could be saved there.

[@WeishairFishingStorm]

Hey guys if you want something that works better in the winter time for air circulation consider this. Try placing your unit near a window and then take a 2x6 or a little thicker and add insulation around it to aid in prevention of heat loss and add 2-3 small lines that run into the box at the bottom and from the top a larger one that goes into the house through the wood board in the window have the fan blow air from inside the house so you are taking warmer air than outside temps to circulate in your house

[@bodryn]

Which is also the principle of a heat pump, except that it gets air from under ground which usually is lots warmer than outside air.

i think if you reverse that rough cut saw blade it works just as well. when cutting pvc siding thats what we did and it worked fine but the teeth on the blade we used were a little smaller.

[@AnsweringAtheism]

It's AIR you're heating guys!. Your metal downspouts, conduit nipples and similar hardware are way stronger (read expensive) than needed to channel the flow of warm air. Laminar flow off the front surface of black painted corrugated paper would work better. Also absolute temperature matters less than BTUs. The volume of air X temperature increase yields a more meaningful number, that's a measure of how much ENERGY is being colected. And your arduous overbuilt construction causes you ask 900.00 a pop for this baby bottle warmer?

[@bodryn]

Sounds right to me: you could build it with corrugated cardboard at the rear, corrugated translucent paneling in front to collect and hold the heat in, and just simple piping at one end of the thing, pushed by a pump. There is even a design on KZbin where the airflow on a similar device is created just by the fact that hot air rises. (convection) It could flow out the top into the room to be heated, and circulate while cool air from below would come back into the heater.

[@JustinCrediblename]

how long is paper going to last when exposed to oxygen and high heat? 100 years? Tell me how long your materials last, please.

[@AnsweringAtheism]

When I build it, I'll tell you. With minimal prep, paper will outlive the house that the panel would be attached to.

[@AnsweringAtheism]

bodryn I'm thinking the cardboard would be enclosed in a box that's insulated on the back and sides. I would also think that clear glazing vs translucent would make the cardboard hotter because of the scattering effect of the translucent material. Of course cost/performance should rule here but there is some very clear corrugated stuff at the home depot. A heat loss path through the glazing would be minimized by encouraging non-turbulent laminar flow over the cardboard. That would be done by carefully introducing the cool air into the bottom of the panel. With laminar flow, the hot air rising from the cardboard would be not have time to reach the glazing before the air gets ducted out at the top of the panel. That would eliminate the need for double/triple glazing by minimizing the heat loss through the front. The laminar flow characteristic will be a function of the slope and height of the panel. Some "cut and try" builds and performance measurements would be needed to optimize the design.

[@bodryn]

***** That all sounds good to me.

I am sure that I miss something, as I don't see how is practical to use a solar heater outside! How is this effective or how do you use it for heating the inside of your home?

[@magnetshack4764]

Easy answer to the blank ends, is to cut alternative slots in the end of the tubes and make them flush to the frame, maybe a little filler of some kind just to make a seal. The air will flow up the tube, across to the adjacent tube and down again to the next adjacent tube bottom. A solar powered computer fan win blow the air into the house. Any savings are lost when you add a non solar powered fan.

I made one of these using a simple plastic vapour barrier over the front of a 4 foot by 6 foot wood box. The back was insulated the sides were not. On a cold -20 Celsius , or -4 Fahrenheit day in northern Ontario, as long as it WAS sunny the thing made heat!! Passive room temperature air 22 Celsius air moved into the box and a cpu fan moved air back into a small duct into the house at 80 Celsius. One issue was dwell time, air moved into the box needed time to warm up, the faster you moved the air the less time it had to heat.

[@slrs3908]

Good, fair question. I agree that many of these units are very small compared to the need. You can light a candle in a room, and it is hot, but there is no way it will raise the temp in the room. These solar units may produce heat, and may only produce heat when the sun is shining...but using more and larger collection units should make a huge difference, even if it only works for part of the time (when the sun shines). Hypothetically, a few days of heat per week for maybe 10 hours a day is much better than nothing and should be worth it.

If you insulate the pipe you should be fine though there is always some loss as the length increaes and splitting it will cut the heat in half between rooms might want to go to one room and then a vent from that one room to the other and then the second room into the intake of the heater or build 2 heaters. Also spliting might cause back drafting so you woukd need a piece like the ones in radiators to make it flow only the way you want. There are videos on the radiator thing on youtube that arent hard to find. this old house explains it well.

That would give a mass flow rate - more or less - and a delta T so we could determine exactly how many BTU the collector delivered.

I would have said to heck with the pipe nipples.. this is a job for a simple sheet metal cutter ..just cut both of the narrow sides and fold .. Done

[@skeebert]

Here's a cheap tip. Wood blades turned backwards work on aluminum. It's what siders use to cut their soffit/facia panels.. Just make sure you go slowly. :)

Good video, although the music made it very difficult to hear you speak at times... its 2018 now 9 years from when you made this. Is it still working?

[@piratepete-thetruthisforevery1]

@robert retka Cool, I will... , thanks very much

[@tetherctrl]

looks good. Maybe use a strip of 1" foam board, and butt up the ends to creat a seal, rather than individual caps. swut i would do.

How do these work in winter and 8 hours of sun?Winter is when we need heat no when its 80 deg. out side

[@27RealMadridd]

Hi justin, i have a question. Does this thing need to face the sun to get the heat from the sunlight? what if i make this solar collector in an apartment that does not face the sun? Will it work? thnkyu :)

[@Rand0mManic]

Find a way to seal it and suck the air out of it. Like evacuated tubes. Light amplitude transfers to heat inside atoms, which does not cross a vacuum, as there is no atoms to do this. This will prevent a lot of convection from inside to the outside. Beware you might start making steam so a pressure release system would be needed. You can make heat from light in winter time where it very cold this way.

nice video, dont worry about the nasayers. I have a question how cold can it be out side before it dont work. either way I like to give it a shot to see if I can use it to keep my shed warm in the winter.

[@justinmy300z]

yup, thats an old video bud. watch some of the new ones. We now mass produce 100 of our commercial heat panels per month. That video was a myth-buster style poke of fun at back yard builders and beer can inventors. Yes they can work, yes we used other materials to try and achieve a better result, but bottom line, we have perfected the true heat panel systems and can do it for less than what anyone at home can. Thats the power of persistance and mass production, thats why you shop at walmart

[@CraftArtist]

Do they work well in the winter zero degrees outside?

[@tonypointer7026]

It work in winter too

[@wrksnfx]

Not to be critical but, you should be measuring the heat at the top tube not the bottom tube due to the laws of thermal dynamics you'll definitely reach higher temperatures because your blowing cold air into your box and forcing the heat down to the cold end of the box thereby lowering the temperature reverse the airflow direction from blow air into the top tube to pulling air out the top and in from the bottom.

Thanks for sharing 🤝

[@richallenmusic]

very cool i found downspouts and pop cans work good im sending you my video

[@johnapelcede9861]

why didn't you use a solar powered fan instead of a blower?

[@robertobrien4799]

AGREE.

[@dgmenace73]

If you are still checking KZbin messages, I have three 4×6 Revere themal water heating panels......I need some tips as far as recirculation and storage. I am only planning on using two of the panels. I would like my well pump and electric pump ran off solar panel and or inverter. Thanks

Cut aluminium with a very fine saw blade, is much better than grinding disc. Something like a band saw will do great.

[@josfos4538]

Hey man, I'm loving the vid. Just moved to Japan and looking forward to building one of these things. Great video-- pour some sugar on me-- awesome addition! Keep doing' what your doing'.

[@domenicsandri2740]

What was outside ambient temperature? How would it work out in the winter?

[@DSCKy]

If you turn a wood blade backwards, it cuts thin metal pretty good...
