That is right, 2004. We know more about energy and wastage now. If you
want external heating get a purpose made LPG umbrella heater. It heats
people directly. If I wanted a little more heat on a patio I would
insulate
under and have no heating. The heat stored in the thermal mass durning
the
day will be given back off. The patio would have to be covered when the
sun
goes in to retain heat given off and south facing to absorb sun all day.

Bloody hell ...

In total agreement with IMM here

Gosh! I never thought it would happen Maxie. You are learning at last.
Keep up the good work.

No, you just got it right for once
