Although the holes in the wall need to be bigger than those for water pipes,
this has to be the simplest way of non-storage heating that I've seen.

My front wall faces SE and often gets sun in the Winter. The solar gain in
mid-Nov. - mid-Jan. isn't enough to be worth drawing back the net
curtains[1], as there's increased loss, but there is worthwhile energy there
and I've been mulling over ways of getting it.

Today, there's been gentle snow, overcast (not too dull, but not bright) and
the temperature stayed just about on freezing. The well-ventilated loft went
from 2.0 deg. to 4.3 deg. during the day, so the force is out there!

Ineptocracy

(in-ep-toc-ra-cy) €“ a system of government where the least capable to
lead are elected by the least capable of producing, and where the
members of society least likely to sustain themselves or succeed, are
rewarded with goods and services paid for by the confiscated wealth of a
diminishing number of producers.

I spent a while wondering where I might get some thin guage aluminium
for a little solar hot water experiment until I realised I chuck loads
of it away every fortnight when the recycling gets collected. Given the
numbers of cans that seem to have accumulated over the last couple of
months, I reckon I could go into competition with the bloke in the video.

Having watched that, I wonder if it's time for a little hot air heating
experiment too!

Did he say how he had joined the cans together or is that his USP?

Been like that here too. I don't want to send my 20 degree room air out
into a system that has a single layer of plastic insulating it from 4
degree outside air in the hope that overcast sun will be warming it more
than it'll lose to the outside - at least, not without proof.

No, but it seemed that they sort of wedged together - OK for air but a bit
fraught for water.

It'd be fairly easy to try it without having holes in the wall. Just make a
crude mock-up and blow some air through it - the proof of the pudding is in
the pulling.

Double glazing makes more sense, maybe triple.
Only running air through it when its warm does too.

Yes, especially for weak sun with low temperatures.
At least it can't freeze or boil (it's already done the latter).

Only running air through it when its warm does too.

That's v. simple - just need 2 'stats, one for room and one for incoming
air.

Why does he need the cans at all? He could just let air circulate through
his green house thingy. Paint the back of it black.

The main problem with this sort of thing is the glazing .

Complete waste of time anyway. All he needs is a window. It is instead of a
window but more expensive and inefficient.

The thing is too small to make a significant difference.

You do need something to absorb the incoming solar because air alone wont.

He could just let air circulate through his green house thingy. Paint the
back of it black.

Wouldn’t have anything like the same surface
area in contact with the air moving thru it.

Nope.

Wrong, as always.

Windows arent cheap.

You can have as many as you like.

On the subject of beer cans....

Why 440ml?

500ml can/bottle - half a litre.
568ml can - a pint.
330ml bottle - third of a litre.
285ml bottle - half a pint.

But why 440ml cans?

No stats required, just plastic film flaps. They open when convection force occurs.

Many cans have contents a mere fraction of an ounce below the actual
volume. There is a bit of space and they obviously want to keep the
right side of weights & measures. So 440 is only a tiny bit below the
454.61 ml exact conversion - which is a similar margin.

panels like this are usually run passively. The light film flap then opens when they get hot, letting the heat in.

- then the plastic flaps might

plastic film's always floppy

A more efficient design is to use 3 layers of black plastic shading mesh. They're placed in such a way that front panel losses are kept very low. Ali cans are probably better suited to multiple glazing though, which can generate very high temps in summer.
