Like, whether it's already melted? :-)

I can almost believe that if there's free-flowing outdoor air behind
the back wall, but not if the back wall is a house wall, which it
should be for a large low-cost air heater, IMO.

Ok, I've started work on my box which is based on an all-aluminium box
with channeling, wooden frame and a polycarb sheet.

I have painted my aluminium collector surface with "gloss enamel - flat
black" spray paint thinking that it didn't matter what paint was used
as long as its black. But I was told this morning that there are
special "light/heat absorbing" paints available and I should use that
Anyone know anything about this paint?
Will enamel paint be good enough?

Dave :)
