Doing a bit of P = I x V on it gives you some problems with resistors...

Taken from the 20 amp fuse rating

20amp x 12volts = 240watts

It'll be less than that, say 15amp instead you still get 180watts

That's why they use air cooled coils as the resistors as they carry alot of current running a fan blower motor.

Iwas opting towards the ceramic with the heatsink but a butchered coil from something more readily available will work.
