Graham,
My website has a view of the method I use for my customers heaters.
Like most systems off the coolers, it varies the temp with the engine,
outside air and velocity. Normally very good at 120 kias at 30 degrees
F or above.
As for demisting, most avionics put off enough heat that a small fan
blowing air from the passenger well and exiting through a hole above the
instruments (on top of the panel, in front of the pilot) works well for
our modest temps here in the SE US. Jerry Hope said it best, "might as
well cool the instruments and keep the windscreen clear!" He used a
small computer cooling fan of 12 volts sucking air from the curved
portion on the passenger side behind his radios and it blows across his
stack, and it exits out the top quite well.

Hi Europaphiles,
Has anyone felt the need for a demisting system in their Europa? If
so,
under what conditions?
Has anyone who has devised a cabin heating system included demisting
as part
of this?
Have you ever used it in anger?
I am considering my cabin heating system from the hot air at the back
of the
radiator, and wondering if I should include any demisting while on the
job -
don't want to have to come back later to do it.
