They generate a lot of heat, but a huge amount of moisture as well -not
in my workshop, thanks.

I literally had one of these LPG space heaters delivered yesterday but
not had chance to see what it's like yet:

Any particular reason you want a diesel one?

The LPG ones I've seen simply blow hot air that has been used for
combustion, so raise humidity levels and lead to rusting of steels and
expansion of wood. The diesel air heaters use a heat exchanger, so the
diesel heats a metal block which has air blown through it - no humidity
increase. I've used the same in camper vans (and similar in aircraft
(burning AVGAS, not diesel)) and they work well.

I would imagine quite a bit cheaper to run than a propane fired one too
(although I could be wrong).

Why a hole for the air intake?
If the room isn't sealed & air can find its way in you only need to vent
the exhaust.

That would blow warm air from inside, through the burner section, to
outside.
