The 3L version of VW Lupo has a glow plug heater on the heating core loop. This way you will have cabin heat before the engine warms up, and any heat left over will go to the engine. If you don't need heat in the cabin, then it will speed up engine warmup.

This is how the kats heaters work that a lot of guys here use. The natural convection will push the water up and through the heater core and back into the engine.

Any more progress? I want mine working before winter

If it fits on the heater hose I say put it on the inlet to the heater core, so if you need to defrost you have that much more heat to ward off the frost.
If you have little or no frost, send more heat to the engine by leaving the blower off.
Here is my kats 400w 120 volt heater:
