It is a heater, yes. It's activated with a finger switch.
The GP is used for filling root canals.

Root Canal Filling Procedure (5min.).wmvby dfsym22,150 views
A far easier method is to use a LARGER/Thicker GP cone and "Cold roll" it between two sterile glass slabs. That removes the contamination factor and prevents you from having to use heat in any way. Futzing around with a heat carrier can potentially cause nicks and irregularities. Cold rolling gives you a custom taper of a SINGLE cone. It takes practice but it works beautifully in things like long canines.

@DeepFill86 Thanks for the tips! I find the combination of cones with heat provides me more customization options for my cones in extremely long canals with wide apical sizes. GP is not sterile out of the pack anyway, and nicks and irregularities on the fabricated cone are condensed with vertical compaction. Those that aren't are filled in by sealer.
Out of curiousity, how much longer are you able to make a GP cone with cold rolling?

do you use on a sterile surface? or you disinfect the gutta by immerse it in naocl for 1-5 min ?
it is possible that the taper will increase at the joining portion and will have a false tug back?

Aseptic surfaces are always a good idea. You would then manage the joined cone as you would any other gutta-percha cone that you use for obturation.
Because of the length of the cone, I try to maintain the taper towards the tip, but create a more parallel-sided cone through the rest of the length. This helps to minimize false tug back.
Thanks for the comment.

Why do not you buy the longer GP? 35 mm is available!

Because I only need one or two long cones every 6 months or so. By joining cones I can customize taper and tip size a bit more precisely.
