finally had the sun out today and i can confirm that even a nine can (3x3)versiom chucks out a lot of heat ..close to 27 degrees ....ive started building the final version ..6 cans high 4 across with a header and footer then a solar panel will be fitted to power pump fans (pc fans)

Nice one Vince. Have been waiting for a report. Maybe you could give us a build diary

Am currently manfully emptying cans jusht to get the matiariarles shoo unnerstan'.

1 get cans...lotsof em
2 take off the ring pull and the bit that gets popped into the can
3 get sharp knife
4 wash cans
5 with sharp knife make a cross in the base of each can and push the cuts inwards -slows the heat and spins it in the can
6 glue cans together
7 make a box to house the cans
8 ensure that you leave enough room for a header and footer ,basically a couple of inches to collect the cold air entering the unit
and one at the top to store the heat
9line the box with foil and insulation
10 perspex front stuck onto thefront of the box

thats the basics ...youtube the videos theres build designs and dimensions on there

i did this first one as a test to see if it worked ...it does


try painting a can black and then standing a glass jug over it for a few minutes and see how hot it gets ...
if i get a new laptop ill provide pics and details ,if not then youll have to make do with the odd post from me

Interesting stuff this, wonder how popular it will become ?

if it means people getting off their arses and away from the idiot box then not very im afraid ...

grait stuff!!! i'm in!!!!!

you know what this mean, i am going to have to throw a couple of partys to get enough cans together

Vince i've been thinking about this project.. need some kind of storage for heat during the day so that we still have heat at night.. am looking at different kinds of brick & so forth to act as a sink..

I can imagine this taking off in rural areas. could be great for cellar/barn heating, and other projects. can't wait to get out into the country myself and start doing projects like this..

ideas like mine and suburban semis don't really mix

what about using night storage bricks from an old night storage heater ? paint em black store them in an insulated box with heat exhausts running into your house ? same principle but using a denser material ...even if it only gives you an hour of heat after sundown thats 365 x 1 hour of heat per year ,thats gotta be a saving on your leccy or gas

[CaptainStoner]

i looked at night storage bricks.. people say they're firebrick or refractory brick.. which seems to be mostly for shielding rather than retention when you look at most suppliers..

[vince noir rock n roll star]

well if thats the case then those white thermal blocks that are used to build houses would be rather nifty i think ..like the thermite blocks but theyre more effiecient ,they look like an aero when you break them open

little update ..


im building a new greenhouse that will lock onto the outside toilet of our house ..the whole back wall of the greenhouse is gonna be made of solar cans possibly with a little solar panel to power a pc fan to pump the air into the house ..

the little can heater i made has run all summer superbly ..heating the toilet ..which in the daytime does not go above 15 deg c normally ..this year its been constant 23 in the day and 18 at night ..success ..now to take it to the next level and really make use of the greenhouse heat and draw that in ..even if we only get 2 hours sun a day thats 2 hours heat for free ..start building this week ..the green house itself will only be 4 ft wide by 4 ft long by 2.4 metres tall .

anyone with suggestions then feel free to tell me

ps i plan on having some 2 litre pop bottles painted black and stuck to the back wall of the greenhouse ,filled with water they should heat up in the day and release heat at night to keep the greenhouse relatively stable heat wise

Nicely done sir. Impressive, just a thought on your current project how close is your greenhouse to the house and how you planning on moving the heat??

[vince noir rock n roll star]

the greenhouse will be fitted as a lean too style so will actually be connected to the house ..i will drill some holes ,probably 3 at around 1" in diameter ..the cans will vent into the holes direct into the house ..i may use the solar panel with a pc fan to pump the warm air in and as its controlled by light the fan will shut off at dusk thus stopping colder air being drawn in at night ...i hope that makes sense

O yeah that makes sense mate, I was just checking I really don't think there would be any point if it was touching the house, I'm guessing that when you say backwall of the greenhouse you mean the wall against the house?

Sounds like your all over mate, if I have a thought I'll pop back but sounds like its under control.

yep thats it exactly
