Pop soda beer can Solar Powered heater furnace panel — Part 1
This is my solar heater just before it was completed. Thanks to shoestring, my simple thoughts, my2cents and others for their thoughts and information, it was a fun project. I so pumped I’m getting 175 degrees out of this thing.
…wow,,,cool,? I meat HOT
did you drink a few of the cans while? building this?
Cansolair? in Canada?
@CROSSiDARKAT that? makes perfect sense. thanks
@OldSkaterGuy To have a better heat transfer you need a turbulent flow.?
This is for water or just air? For house heating, with warmer? air?
that had to be alot of work? to do each can with the swirl and cut out on it.
Do they all have to be regular size or? can small (like Sprite minis)ones be used.
@007westleysadler The problem with that idea is that the bricks would soak up heat when the unit is first exposed to light for about the same time as it would give heat back after? the sun went down. The net result would be zero sum.
@zsnowshredder First you have done a fantastic job building your heater. Excellent craftsmanship.
Constructive criticism alert;
The goal when building is not simply to measure a high temp out the exhaust port, but to measure a high temp when moving 300-900cfm of air through the box. If you can run 800-900cfm and? the air is warmer then 85 degrees, IMO your design is fantastically successful.
To compare your design with others there are other factors, but raw CFM is a good start.
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?
should? have included before and after (in use) to show it’s capacity.. are fins worth the trouble? The hold should be enough to slow down the air…which was proven by richallenmusic, the king of pop can heater presentations!
How many BTU are you? getting with it on a full sunny day?
Thats awesome I am getting so frustrated with the rising cost of heating and have been looking for alternatives thank you ?
@OldSkaterGuy as i understand it, the fan blows air into a header tank, its the high pressure of the air? in this chamber that drives the air through the cans, so any ‘swirling’ of the air by the fan is negated once the air is in the header..
outstanding!! i just love these types of projects!! kudos to you sir, kudos!
Thinking out load for a sec… if you joined three of? the columns together, two one end and two on the other (kinda like a big snake:) you could trap the air for longer and heat it more..
175 degrees is in? farenhait ?
what temperature was outside when you did a test?
best regards
Will it work with thermo glass (double glaze), or? will it just get too hot and burn?
@zsnowshredder can i used i PC fan ?? could you send me? techical data ?
regards
@zsnowshredder gotcha.. but don’t you have a fan blowing the air through the cans? Would not the swirling motion of the fan not keep the air moving in a circular motion throughout the cans? If you pulling the air with a fan I? could see the need for the swirls. But not pushing it through.
@OldSkaterGuy You are trying to swirl the air to collect the heat off the inside of black cans, this way the air moves through quickly and grabs the most amount of heat. Google “Hungarian solar heater” for more info.?
@geochoros? CD Technology solar attic fan….google it
@zsnowshredder hello sr. could you tell me what kind of? fan normally you used?? tks from chile
Wouldn’t smaller holes in intervals provide the same effect as the fins? Plus it would give the air some momentum as it was pushed back into the? house.?.?
A eazy way to go green is to use sliding glass doors that are often free road side or on craigslist, a set will be the same size, and if you get lucky the extursions can be used as a frame, or just buy patio beam extursion, look at a half peice, and it,s perfect for a frame to hold the glass and insulation. this gives a 4×8 collector with tempered glass, that can be? hung or set at angel. now if you could remove the air from the box, all the better.
