My experience with the Ti / SiC wicked heater in the Alpha Centauri including the EHD heater is that when cold and for that first initial instant of time you press the button and apply heat it's 100% heat from the titanium wire. BUT: as soon as that Ti wire starts heating up, even inside of the first second of heat, it begins transferring more heat into the SiC. So the longer your lung ful lasts, the more pulses of power you apply, more heat is transferred into the SiC and a greater percentage of the conductive heat comes from the SiC itself. I have not used the later sirius/canopus styles, but would imagine with the wire wrapped inside the SiC instead of the outside that the Ti wire would be even more effective at transferring heat into the SiC wick and as they heat, that even more of the heat to the load would come from SiC. I would guess at the Trinity's design to even improve on the heat transfer to SiC wick as it does look like a further evolution of the Canopus style coil if i am correct? Sorry for all the speculation as I'm a few generations behind W9's tech at this point.
