The heater core supply pipes are more than likely connected to the block directly. If you want to thermosiphon through there you will have to pay close attention to your pipe layout. I tried to get mine to thermosiphon but i had no joy there.
I made up a 1KW, convertable to 2 or 3KW...heh!, tank type heater and put a domestic circulation pump on it. Good flowrate thats for sure!
Then i teed off the cabin heater pipes to the heater. The radiator return pipe went through the thermostat on the engine block so connecting there was not going to work. This means that i have to make sure my cabin heater control is set to cold. It's not a biggie as it helps keep frost off my window if i open it a little.
But my heat up times are still long. I guess the alloy block is good at dumping heat. I have a layer of foiled insulation on top of the engine but it's getting shabby after a years driving. Still, a warm engine at stsrtup is hard to beat.
