Anyone got useful experience or recommendations for links / books
reading on _very_ low capital cost solar heating for space-heating of
workshops? I'm looking at the real "Scrapyard Challenge" end of the
problem, with almost everything being built from recycled radiators
etc.

In reality most of the DIY solar stuff don't work that well in the depths of
winter when ther is little sun and its freezing outside, just when you need
the heat in the workshop.

Build a waste oil heater instead
