home made solar air heater/finished

[NewChristianSoldiers]

What do you do when it is 5 degrees outside then this will produce heat of 10 degrees? Then what do you do throw on your arctic parka or crank up the thermostat to 50 degrees? It looks like this only warms up only one roomof your entire house so how do you heat the other rooms or do you huddle in the kitchen for the winters? This might be good for an small camper or shed but not ideal for a house.

[NewChristianSoldiers]

So if it is 20 degrees outside then this can bring in 40 degree air into your house an increase of 20 degrees? That doesn't seem very efficient at all.

[SmallWindTurbines]

Cool Project, I like it man.

[munkeeblue]

Tbh i think the reason you smell the paint is because of the heat its getting at it and as long as the heat is there there will be a smell. You should have used special heat proof paints. Im guessing you only used normal acrylics :P...... ah well its a nice idea :D you should tweak it and go all out and make a massive one :O lol

[cchanderson]

too bad you used gloss black instead of flat black, you lost 25% ;0(.

[widdy2007]

Are the cans empty cans of coke or are they still unopened?

[theemurf]

@widdy2007 Empty cans. Together they form one long pipe, going up and down repeatedly, the air is circulated by an extractor fan (power by an electric solar panel) and is heated up by sunlight.

[magna59]

Great panel, but the connections 22 & 15 mm. I know the tempetation of not wanting to damage the house, but you've made all that effort to make a panel, and then waste a lot of the heat through not being willing to take a brick out of the wall. Take you courage in both hands and take a brick out so you can get the heat in !

[bscfrnd1]

I am going to try high temperature adheasive spray over a primed aluminum sheet and then covering it with activated carbon powder to see if i can increase the collector surface area . I just have to find an adheasive that can withstand very high temperature . If anyone knows of one I would appreciate it. I am in the design process right now . I have been cading it up for a week or so and researching suppliers for electrical componenets. I think the cans are ok but it looks like a lot of work

[widdy2007]

@bscfrnd1 No More Nails have just released a new and improved one - it sticks in 10 seconds.

[jeffpicks]

How many CFM of air can you get through 22mm opening? not much I bet... looks to me like you have a huge panel capable of producing a reasonable amount of BTU but with that tiny opening you can't use it...

[leetiso]

Which country are you in? You mention £'s. Are you in britain?

[helloman1976]

Nice work, anything you would have done differently now? Also, how did you end up piping the heat into your house? Thanks!

[junkyardnut]

i JUST DONT UNDERSTAND THE NEED TO USE CANS ??????? OR FLEXIBLE TUBING AND SUCH.. Why not just a simple cold frame with nothing inside but a blower that is it.. can you explain the advantages of cans????

[bscfrnd1]

@junkyardnut Using round cans increases the surface area of the collector plate.The thin wall alluminum in the manifold configuration alows for extreamly efficient heat exchange. The thin aluminum in the can heats extreamly fast when exposed to the sun and also cools quickly.

[junkyardnut]

@bscfrnd1 Why dont you check with National Renewable Energy Laboratory (NREL) to establish validation of beer can theory. They can compare beer cans or without in a controlled experiment. I dont have any beer can heater so I cannot really make any baseless argument with your beer can crowd. maybe you are right after all. so I encourage you to go to get validation. For myself, I simply use mirror remanents found in remodeling projects or glass shops and mount them on dirt ground or frame (cont)

[junkyardnut]

@bscfrnd1 cont from first one..and bounce sunlight from the southenr sky and toward the shady northern sides of my houses. Through my glass sliding door and huge living room window, my mirrors illuminate the indoors as well as heat them. I nailed 2x8 inch lumber boards to 4x4 foot sheathing boards through drilled holes that act as loose hinges. 2x8 inch boards is heavy enough to withstand winds or 2x10 inch lumber boards may be better.Cost is very negiblie..heating performance is outstanding!!

[junkyardnut]

@bscfrnd1 I find it so strange that mirror retailers has no large mirror mounts that can hold mirrors. All I see is those sets of crummy clear plastic mounts with skinny tiny screws that is useless for exterior uses.. I have to fashion mounts out of bent sheet metal and appropriate bolt/nuts. to secure heavy mirrors against the sheating boards . Hardware stores lack so many things that can be used for any kind of solar uses.. It is so woeful!! Fore example, I couldnt find any ram mounts, etc.

[exploregirl]

Thank zou for video. I really need to know does this heater made of cans work during harsh wintertime because during winter there are low temperatures and aluminium cans have ability to get hot quickly but to get cold also quicklu. ALSO ONE VERY IMPORTANT QUESTION IS CONSIDERING THE FACT THAT ALUMINIUM IS METAL WHAT HAPPENS DURING STORMS WHEN THERES LIGHTENING DOES A PANEL ATRACTS OR APSORBS LIGHNTENING. sO WILL A LIGHTENING STRIKE A HEATER PANEL OR NOT.

[ptrbrown]

Why are people who nothing about solar heating so negative?

No it isn't a perfect replacement for conventional heating methods. It isn't meant to be. It supplements conventional heating.

[kkv1121]

Right



[combatvetlawstudent]

outstanding!

[tutor1006]

nice work man. I am sure it does work and when i get back to my cold country i am going to check it out. It is annoying to read comments from people who haven't tried and have big statements to make right!

[MrNigel1340]

Good to see the heater works, hopefully will save you money as well, working on my own system at the moment that will go under the roof tiles and preheat water for our house, will be putting it on you tube eventually, keep up the inspirational research, regards Doc Cox

[Fire4FX]

If this was to be fixed permanently in place then you could put some concrete pavers behind the cans & paint the entire thing black & that should give off heat even in the evening. Also, is there a particular reason you used aluminum cans & not rain water tubing?

[MrBudwv]

What was the outside Temp here?

[donamoor69]

temp autside 22c

haahahaha

de ce mai trebuie sa incalzesti in casa

must work outside in-20c

[DaySunny100]

Great job. do you show how to make it from start? love to make one for me..

[laithnour]

yeah, you gave bollox-all information

[PiPphiltitley]

quality idea mate. but as an ex plumber you need to insulate your 15mm pipe mate, i know what you said about hiding the pipes so the 1st thing that jumped in to my head is Reflective Foil Insulation and Loft Insulation this is quit new stuff 3 to 5mm thick foil sided multi layer stuff but gives the insolation of 6'' traditional roof/loft insolation, then may be you could paint it to match your window frames.

nice one mate

stay safe pip

[real80smusic]

too vague of a video. not enough detail. explain it simply

[djbreeduk]

have just moved onto a boat and am looking at free heating and power systems as i do not live in a marina but on the river itself which is great but you do miss being able to just turn on a leccy switch lol,looks good m8 will have to have a go and let you know how i got on.

[saramick]

looks like a really well thought out solar heater. Just wondering if you had thought of insulating the copper piping leading into the house... Looks like you come from a pretty cold part of the world and so could lose a lot of heat with a bit of a cool breaze or a set of cold bricks that you have the copper pipe resting against.

Cheers M

[thegreatkoua]

how is that work heating water

[lsmith254]

Since i put a link in my post I am not sure it made it through. Search Beer collector (!) Beer collector (!) and see how she does it...the Hungarians have it down! Pass the outer cans over a flame to help them expand and to fit them easier; it increases the thickness of the aluminum walls and you get higher temps. Also, if you are using a hole saw to cut out the bottoms, save the fallouts, and put slits in them to make tiny pinwheels. Glue these into the bottom three rows of cans.

[lsmith254]

Your outlet port should be larger, about four inches in diameter...when you force warmer air through a smaller opening it is cooled, and you have wasted energy. Check out BEERCOLLECTOR! BEERCOLLECTOR! .com, and see how they do it. You can pass the cut cans over a flame to make the outer can fit much easier, otherwise it will only go on about 1/4 to 3/8 of an inch. In effect, she is increasing the thickness of the aluminum walls, thereby increasing heat gain. (continued...)

[ReR0LL]

Nice!! Have to make one! ^_^

[slayin4free]

you can still get sun burnt when its couldy

[roguedavid]

My thoughts,

- This device will work in the winter. Although the temperature expelled will be much lower than in the summer, it will still be much higher than that drawn into the system. Cloudy days may only be a fraction.

- The heat being put into your house means that your household system will not need to work as hard and if on a thermostate will cut off much sooner saving you money.

- It does not matter what is used, it's great that the system has cost next to nothing and is working.

[WoundedEgo]

Sweet!

What purpose does the solar panel serve?

[Havryl]

Probably to power the electric fan at the outlet of the heater.

[gazbmw0]

great build i like the fact that its so cheap and uses the waste that would normaly be dumped and also saves money on the heating bill

thanks for showing your work on youtube its inspired me to build my own

[bloggycreek]

Nice heater! Did it cost much to build?

[humbertini900]

Not really total cost as mentioned in the description £5, just using waste from building site.

Thank you

[bernithebiker]

@bloggycreek No, but got very drunk drinking all the beer.....

[bloggycreek]

@bernithebiker Sounds like a win-win situation.

[humbertini900]

why do you need 30 more, tell me your calculations please.

[WONDOCTORJ]

so if u build 30 more of those u might warm your house 10 degrees ---wow !

[xSloboxx]

Hot air comes out of top of the window and cold air comes in the bottom. You should have placed it at the bottom.

[cgrove225]

You need to go big or go home. You need more air exchange to heat your house. Mine panel is 4 X 8 and i'm using 6" Pipe with a big fan. My panel is heating 5 rooms from 64 F to 72 F in 32F outdoor temp.

[humbertini900]

Hi cgrove225, thank you for your amazing positive comment, by the way, I AM at home, it is warm and cosy, and I don't need the massive 6 inch pipe with a big fan, bla bla bla, mine is better than yours crap, if you are happy with yours and I am very happy with mine, what's the problem?

[bornfromground]

Don't forget to insulate the copper line running up the window sill, you don't wanna give a way heat in the winter.

NIce build by the way!

[IbnAlla]

Won`t work during winter time.

[bornfromground]

then explain how a green house effect works

[humbertini900]

why not isn't there daylight in the winter???, what matters is the solar radiation hitting the panel I have had this now for about 2 years and I have news for you it DOES WORK, AND ACTUALLY IT WORKS REALLY NICE, ask anyone that has built one and see their answers, by the way in winter while you are using gas or the mains to keep you warm, I'll be using this heater and saving money while doing so.

Thank you for your comment anyway

[IbnAlla]

Some "expert" told me it wouldn`t.

But great that it does!

[humbertini900]

I actually took the time to show you guys that it works and that it makes the house warmer during the day.

I would be suspicious of your expert's opinion, since I actually show it here that its working, anyhow you can't win them all (lol),

[souleeze]

This may seem like a dumb question but what about in the summer when you don't want all this heat coming into the house..how do you shut it down..by closing the vent but then wouldn't the excessive heat warp the heck out of the inside etc..or do you just take it off the house?

[bscfrnd1]

@IbnAlla I used mine in the coldest month average temperature 40 F and my heating bill was reduced fro 300.00 US to 174.00. Its a good savings and I had a small unit. The only draw back i had was not being tied in to the central duct for more even heat distribution .

[furbsmom]

youd think the cans would get hotter without the glass over them, but do you need that to capture the heat?

[ffsallnamestaken]

The air is taken from inside your house so you want the glass there :)

[sohighlyunlikely]

you need the trapped air between the cans and the glass as an insulator, otherwise most the heat gathered would radiate back to the outside.

[ArashiNage]

Awesome project man! a step by step would be cool, I would love to try and make one.

[sco215]

im thinking the pipe will cool the air before it makes it inside. but your almost there!

[321ozzy]

Your design looks terrific!

I agree with the rest that an instruction video on how to build it would clarify some doubts I have. e.g. 1) do the bottom cans all have a seperate air inlet? 2) Are the cans at the top all connected with one tube to the outlet? Thank you in advance for your response.

[heelspurs]

Just use reflective mylar taped to 4x8 insulation board to reflect light into a window.

[Maccan]

Good Job. Unfortunately you do not show a step-by-step process in the construction. Please make another video showing the construction and I sure many viewers will follow your design to heat their homes. Thank You

[SmalltimR]

lol

Your copper tubing will effectively cool the heat as your panel pumps it out.

At the very least, you should insulate your tubing to avoid heat loss.

[colterczyruk]

pvc,abs or conduit would be way better

[easynoteguy1]

Where did you get the solar panel from cos i want i small one

[colterczyruk]

walmart or kmart, zellers, autopart stores

[theshires]

Hey, i live in Canada, with sometimes upwards of -40 winters. At the moment it's -25.C My house is very poorly insulated and I'd love to try out one of these. Have you made a how to step by step vid for those of us who are slightly moronic?

[ovila7]

To measure the heat that comes out your pipe

.. you should use a thermo couple mose good DVM meters have them...

GOOD IDEA

[mweezy]

....or he could have just used a high-heat paint(for about $30) and let it completely dry before he starts using the device. Also, he could have purchased a thermal heat sleeve(3' & 1" I.D. for about $34.99) from JEGS web site to protect the pipe. But obviously, all those things would just jack up the total cost of the device, but for a good cause.

[FelixTheCat86]

Do you have the steps to make this?

[centervilletn]

it will work better if you can hook the intake up to the inside of your house...heating already warmed air will increase its effectiveness X 20 or more degrees.

[bigdaddydylan]

Throw a filter in the pipe shaft if the paint keeps stinking.

[thimpsy]

i was just wondering why you didn't use headers for the top and bottom? i have been checking out a bunch of these passive solar heaters because i am going to start one in the next couple of weeks and most i have seen have headers for the ends of each row of cans. just wondering what your thoughts were.

thanks for your video.

[centervilletn]

I built one using the same idea...but living in the southeast us..i figured that i could build an easier model...i used a piece of galva-lume roofing material..painted it flat black..attached a 3 rows of cans to the back of the galva-lume to create a baffle..installed the galva-lume inside my insulated box,faced with 1/4 inch polycarbonate glass,cut two 4 inch holes in back of the box(0ne at the top one at the bottom..and attached to the south side of the house..165dgs.thinking about a small fan

[kelltiozim]

Good job, thanks for finishing it as I suggested, now it will work! Radical status deal. Open the blinds to your windows!!! Cumon!

[brianwesley28]

How large is your house, in square feet, or square meters, or whatever? What are the average, annual, seasonal temperatures where you live? How well is your house insulated? I'm curious to hear all of these things because I'm interested in constructing something similar and I would like to have a good idea as to how many I can expect to construct to heat the house where I live? Thanks.

[ehgemus]

what did you glue the cans together with?

[humbertini900]

hi rose the cans are stuck together on top of one another by using silicone

[rosemacaskie]

I saw several of your videos and it seems you where using glue to stick the cans together. I listened to variouse youtube videos on Mr Meaney and i understood from one that he sort of hooks the cans together. I have tried to cut holes in variouse ways to get cans to catch together but hardly been very sucessfull yet but i'm not a great handy woman. I reckon that if the house gets warm during the day it lessens the problem at night even if it does not heat at night. rose madrid.

[mlarar]

Please give us an update of your project, did you install it and it worked as expected? is it still little bit warm at night? Something I didn't understand is where the cold air is coming from, do you have something to inhale the cold air? It would be great if you could provide a step by step guide. Thanks for sharing!

[necasm]

great thing, but i suggest for you to use plastic not metal pipes to do not loose the heat :)

[googletubgirl]

it looks great, you did a good job but I keep wondering. If it's sunny outside do you really need a heater? I'm not getting it. How will it work during the winter?

I know how it works I just don't understand the use.

Anyone clear that up for me?

[nastymittens]

well, unless you live in a tent, your house is probably insulated. soooo pump in warm air, house heats up, insulation stops warm air leaving. cat is warm during day, and when you get home, your house will be warmer than if you left in the morning without the heater on...

[humbertini900]

well said nastymittens that is spot on, the house gets warm during the day so at night i don't have to put the heating on, well said once again

humbertini900

[gomuti]

it can be cloudy and it will still collect a good amount of heat

[pampanolo]

that pipe outside the window will low the temperature of the warm air a little bit on the way.will be better covered with foam or something.cogratulations good job.

greatings from spain.

[Struckgold]

what about night time? It heats the house while your at work? Keeps the cats warm? Sorry?

[nastymittens]

easy, work at night!

[Heretotheremovers]

I finished my prototype yesterday and put it outside. Got great results... I'm mounting it tomorrow. I actually got a 100 degree gain drawing in the open air. I will post video soon.

[mutedmajority]

Or you can just buy black curtians and do the same thing. Americans spent thousands of dollars coming up with a pen that would work in zero gravity, russians just used a pencil. lol.

[whatnofish]

to get heat at night.. i think using heat bricks like econ 7 heating.. if this gives out this type of heat then i am sure after a few hrs of heating the bricks will carry on for a few hrs after dark

[JustConquering]

Damm Freaking cool

Make a Video how u can make it

I wat to have 1

[mostvideosolar]

Just about finished my "portable" can solar heater, had a little delay with a company who were to make my top & bottom chambers, they took too long so I went & made them myself.

The perspex will be sealed on tomorrow & the final photo's taken for the video & I'll up as soon as. I have made a little modification to that of the canadians design..lol. p.s theres a little experiment at the end of the video for u skeptics to try

thanks..humbertini900

[DrewDawg50]

What about when it's really cold outside?

[benjamin1254]

it would still heat the inside regardless.. the black is a conductor of heat from the sun. IT will increase the temp probly up to 100 or so...

[tillycupcake]

home made...I'm impressed...dude,that's amazing!

[YouAdamNazzkl0wn]

If they say you need a 40 euro battery to fun a 5 euro fan, ask them witch panel will run the fan without a battery.

[mostvideosolar]

Luvely stuff, today I'm gettin the wood framing delivered for my project, cans are already glued & ready. I have based my can heater round the canadian & hungarian design, no spec was given for the large unit so I am building a smaller test unit using 81 cans first (like urs), I have inserted deflector fins into each can & will use 4 comp fans for the small unit, I have recorded all sizes of the project & will upload photo's etc once complete. p.s. u can add more fans to your unit & larger pipe

[ragnar336]

how cold of weather does this work in?

[kmartin73]

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

[YouAdamNazzkl0wn]

Is your panel big enough??

A little computer fan shouldn't require very much juice.

[kmartin73]

hi i have a 1.5watt 12 Volt Battery maintainer solar panel from maplin unfortunately i do not know the wattage of the computer fan.i have been to maplin's and they say that i need a battery.

are there different types of panel.

thanks for your reply

[JohnSNeely]

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.

[rasoros]

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) ?

[sockosockosocko]

lovely work. i sent you an email.

[r2d4cp3o]

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?

[marcesanson]

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?

[humbertini900]

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

cheers

[RoboTekno]

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

[ZELPHOR]

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.

[teainthesahara]

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!

[moneymagnetelizabeth]

This is great. How many rooms does it heat and is this something that I could do too Are there plans to build this

[indyhollow]

ive been planing to build one like this for awhile now. when i do im gonna build it on a 4x8 sheet. the only difference in mine is im going to seal the top of the colomuns in the box from the bottom. making i seperate airspace. make the air move through the cans instead of over them. plus im going to make smaller holes in mine to slow the air down a little. the longer itsits in the cans, the hotter it will be i believe. just these 2 improvements should net another 15-20 degrees. nice buld though

[humbertini900]

Hi mate, the air does go through the cans, the more air you have travelling the warmer your house will get, better to have a constant 35 degrees into your house than have 45 degrees for a while, but having said that go for it it really is a nice productive build.

[tobykutter1006]

could you tell me about the small solar panel you have on the frame and what it does

[humbertini900]

the solar panel powers the little computer fan to push the air in the house

[Ricangal]

Must the tubes be metal or can you use lengths of PVC, painted black? And yes, where is the intake hole located?

[humbertini900]

I think you can use anything that absorbs heat, maybe the pvc will degrade faster than the aluminium cans, all the row of cans have holes at the bottom and at the bottom of the cans

[myfortune4u123]

Wow! You have me so inspired! This is a must build. Just a few quick questions (if you don't mind my asking):

1. How do you secure or mount the cans to the insullation?

2. Do you have another hole at the bottom for intake, or just one at the top with the fan for an output?

3. How much space did you leave between the cans from the bottom/top?

4. Do you drill any holes in the bottom cans or leave them entact?

Any help would be greatly appreciated. Again, Thank You for the inspiration!

[humbertini900]

The cans are secured with silicone, all the cans have holes at the bottom and the bottom bit on the ply has all air intake, first get the window and then build you box allowing for insulation on the side and see how many rows of cans fit horizontally, if you need any more advice send me a e-mail

cheers

[manit77]

nice job, i'm going to build one for next winter

[moomar1]

You want cycle the indoor air through this otherwise as you pump this air in it will be forced out the other side of ya house

[humbertini900]

well said starbuudh, exactly right since i have made this heater and just leave it to do its job, my house feels much much warmer, on sunny days it can actually get too warm, hybridracers the pipes are already insulated and yes you were right it doesn't lose soo much heat.

cheers

[starbuudh]

The cans increase the total heat exchange area slightly over just a flat black surface, making it slightly more efficient than a flat plate.

You wouldn't want to try to store all the heat (in a mass storage form) so close behind the glass/plastic anyway - the really useful heat is already stored inside the house itself after it has been heated all day by a little heater like this one - nice job!!

[hybridracers]

Just a couple flawas I see in your design. The cans by themselves have no thermal mass so they dissapate heat too quickly after the sun sets. You could pour black sand around and inbetween the cans for more thermal mass. Second is that you didnt insulate your piping into the window so you lose tons of heat that way. Great idea, maybe try some of my recommendations and see how much better it gets.

[truthspeaker2000]

Are the cans filled with water ?

Because the cans alone can´t keep

hot very long without sun.

Black Stones are an alternative maybe,

because they store the heat very much

longer than aluminium.

[rasoros]

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.

[humbertini900]

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.

[leemer12]

but, i do imagine if it had some water the heat would last a little longer as the sun goes down plus the humidty level would be higher thus more effeicent on heating the air, in the winter time that would be a little harder to deal with then on the outside though. Maybe one could inject a little water in the winter time to basically make a little steam, I hate dry winter heat makes my sinuses crazy I run humidifers and still not enough plus keeps the heating bill down a tad bit.

[artarasekhi]

Nice job, But I still can't understand the reason for using the cans. I think If you just coat it with black colour you will get the same amount of heat.

[humbertini900]

yes but the cans get extremelly hot through the day and when the sun goes down the air still travelling through the cans will get warmer, that's my theory anyway, and I am sticking to it, cause it works, cheers for your comments

[trailkeeper]

I think the sun energy is about 1000 Watts per square meter on the ground in the summer noon sun. Of course it depends on the efficiency of the system; air, water, solar electric of how much energy can be transferred to it. Also, I guess a large collector mass such as perhaps a 1/8 inch to 1/4 inch aluminum plate behind the cans could hold some condensed stored energy at the cost of money and "warm up" time for the system.

[mylarjorgen]

great vid man. Just a few thoughts: temp, Centigrade should be metioned as the yanks use Farenheit, & a quick diagram of how it works would be great as it wasn't til i read a comment about drinking the pop (soda) that i was sure that the cans were empty & not using the liquid for storage (same principle as the fridge (cooler) built from full cans of beer.(Hmmm....possible design flaw in that one:o)) & the space inside the frame for heating the air. & put a black, full radiator behind the cans:o)

[ejbh3160]

A solar powered ionizer would take away the smell of paint & would make clean oxygen rich & toxin free air (its like those ionisers that filtre the air for asthma sufferers).

[RevolutionaryJam]

how would one of these work in Scotland? would it still yield a benefit?

[humbertini900]

if you get a good amount of sunshine then it would be beneficial has it doesn't matter, how cold it is outside, the temperature going in is double or more so, i personally think its worth since it heats your house up during the day, so it feels warm, and gives your boiler a break.cheers for your comments, I also like you, hate to pay the big b**tard power companies the huge amount of money to live in a bit of comfort, so anything helps, even if you only end up using it for 1 month or 2 up there.

i wouldn't really know where to start makign on:/ i amn't very technically minded

is one of your videos an account of how to do it?

[RevolutionaryJam]

u r awesome

unplug from the system and stop being fucked for a buck! way-hey!

22C is like 70F? right? Why do you have a coat on? :p You said 22 centigrade, right?

I'm confused, why would you want heat on a 70F day? I'd think you would want cool air.

I'm guessing it still works on a sunny winters day?

[humbertini900]

hi mate, i don't have a coat on it's a jumper, and yes the sun was hitting the outside thermostat and made it go up to 22c, but its winter now and the air feels really cold, so the air going into the unit is around 16c and comming out at 40+ continously, and yes it does work now which is winter with somme sunny days, but outside the house feels cold.

cheers

Cool. I gots my cans, I just need to drink the pop first. lol. Then I'll put the Krylon black on there and see what I can get out of it. I'm going to try the vacuum (pull approach) vs. the fan approach. I'll post vids if i get it to work!

[rasoros]

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.

[radarhero]

looks great - how does it fair in the winter? and what is the average temperature that you get during winter?

[humbertini900]

yes the pipe around the window is now insulated and man does it get hot inside, its also amazing how much heat the box retains, has even after 2 hours after the sun is gone the air is still pretty warm.

cheers for your comments guys

I think you should make them and sell them to people in your community bet you could get at least £50 a pop and you'd be doing something very positive!

[galtavista]

I get amazed at your determination. Good job. Question: Do you need to insulate the copper pipe that is around the window? As soon as it leaves the panel it starts loosing heat. So you will not get 47C inside the house.Correct? What are your plans to minimize the heat loss?

Keep us posted.

[TannerLamm]

Where did you get the plans for this ????? can you send them to me???

[lewisreford]

nice one are you goignt to insulate the copper pipe around the window? you may loose some haet threw conduction, would be interesting to see how warm it makes your living room! nice one!

[humbertini900]

hi gug, basically at the bottom of the box there is a row of holes that line up with the holes at the bottom of the cans, so every can that you see is drilled at the bottom and stacked on top of the other so the air goes inside tha cans, very effictive

[gug1970]

thanks, looks very interesting.

[scrimon]

Nice one!  thankyou

[gug1970]

thats great.

If you do another video, can you show the air intake.

How have you forced the air through the cans rather than both through and over - or didnt you worry too much about that.

Thanks
