Finally ive started on my ss. But now i need to make a loaddummy. I have a 62x62mm tec specced for 320w at 15.4v

Could i make it into a dummy? Or would it simply be easier to get a cartridge heater? Another problem im having is i cant find any cartridge heaters here in sweden, are there no resellers here? :S
Would be happy if i could use my tec but im open for suggestions. The evap has a diam of 42mm.
