Am sat on my yacht, toasting my toes in the warm air from my Eberspacher, wondering exactly where it's coming from.
How do they work exactly?

Tried that. No joy. Same with Wikipedia.

Hmmm.
So you two don't know the answer either then.
PS. How exactly are you heating your location?

So you want a technical answer !
Okay, I will try, the fuel (either diesel or parafin) is burned in the combustion chamber and the heated air in the exchange chamber is then circulated around the pipe work by the fan.
Is that enough or do you need more ? If so try this web page

p.s. I have a water based Eberspacher system ready to go into the boat, when I have it weather proofed. So instead of blowing warm air around my boat I shall have radiators to heat her.

Diesel is pulse injected into a heat exchanger & burnt. Cool air from boat is passed over the heat exchanger & pumped around pipes into the cabin. Air for combustion & exhaust fumes are kept seperate from the cabin heating air to prevent poisoning or suffocating you.
Does that help?

the 12volt connects to the glow plug
and also connects up to fuel pump;
but it also connects to the blower,
NOW HEAR THE WORD OF THE LORD.
DEM TOES DEM TOES GONNA GET REAL HOTX3
now hearb the word of the Ludd!
The diesel comes up through the fuel pump
and lands in the combustion chamber
where it comes into contact with the gow plug
andthen the whole thing explodes!
chorus
The cold air gets blown through the matrix
and does aclever heat exchange trick
so it heats all your feet with no ndanger
NOW hear the word of the Ludd
chorus AAMEEEEN

Sorry, yep, my fault - should have explained myself better.
I understand all of the above explanations... but what I'm not clear on exactly is how the combustion occurs.
Let me clarify...
If I pump fuel, even aerated fuel, into a chamber, even a warmed (glow plug) chamber, it's not going to combust... unless there's some serious heat or a spark.
Combustion engine does naught at the glow plug warming moment. Only when there's some serious compression ratio going on does combustion occur - due to some serious heat as a result of some serious compression ratio...
What am I missing?

Fuel is sprayed int fuel screen surrounding glow plug which atomises it,then self feeding---IMHO

Find with mine press the bottom right button and heat comes out!
Top right makes it hotter
That how it works.
as long as it works OK
Be more worried why it does not work if and when this happens

The glow plug in an Ebersplutter is exactly that - a GLOW plug - the MF'r glows red hot which is hot enough to ignite the diesel (or paraffin or heaven forbid, petrol). The GLOW plug is surrounded by a mesh screen which remains hot due to the combustion of the fuel so combustion is self sustaining after the GLOW plug is de-energised.

The clever bit is that a temperature sensor controls the rate of flow of fuel.

Make it simpler Cliff, the tick tick pump pumps fuel in to the eber, it is then fed (under lo pressure) and allowed to dribble over a stainless (sometimes a wick in the old ones) mesh, inside the mesh is a glow plug, this heats to red heat on start up and starts the diesel burning, when the mesh and combustion chamber are hot enough then the glo plug goes off BUT the mesh continues to glow, think tilly lamps, and continues the process untill the fuel is shut off. Go to www.espar.com and download a manual, the cutaway drawing is good for you to see inside.
