He-219 de-icing heaters power source?
 

Were the three heaters used to deice the wings and horizontal stabilizer of the Uhu gasoline-fired or electric? I had a gas heater in the Piper Aztec that I flew, so I know they work well and are safe, but the one diagram I've seen of the He-219 heaters suggests they are electric.

Also, did they provide cabin heat as well?

This is looking aft in the aft fuselage of the NASM He-219. (A horizontal stab picture as well.)
You can see the heating ducts for the tail. I'm not sure if the heat is electrically generated or gas generated.
I haven't noticed any exhaust manifolds/ducts on the aft fuselage of a He-219 for a gas generated heater though.

All three heaters (Kärcher-Öfen BL 30/U) on the He 219 run on aviation gasoline. The exhaust for the one in the rear fuselage is situated on the left hand side of the rear fuselage, just below and slightly in front of the left stab.

The exhausts for the two wing mounted heaters are located on top of the wings, just outboard of the engine nacelles.

Albeit a model, but you'll see the heater exhausts pretty well on my 1/72 HE 219A-2: http://modelingmadness.com/review/axis/luft/cai219.htm

Stephan,

Attached are two images of the NASM He219 wing during restoration, with what I believe is the Karch Heater unit.

Kärcher 'ovens' had their own petrol supply. Here's a piece I compiled on my blog on the heaters as fitted in the Ju 88 G
