It's not really a convection vape but a hybrid like the Fury 2. I don't know why HR keeps bragging on it like it's convection only with a touch of conduction.
Again the Fierce is like the Fury 2 or any Arizer device where you turn it on and it heats up to temp in the first 30 seconds or so.
Oh and no ghost hits with these hybrid session vapes. The downside is you're kinda cooking your material if you just sit there staring into space for a minute or two between draws.
I agree, and will even go a step further. There's really no such thing as a 'hybrid' vape when it comes to making vapor. Conduction, convection and radiation are three separate modes, each with it's own rules.....Thermodynamics rules. Like 'heat flows from hot to cold'? That means, for instance, for hot air to provide the heat (energy) needed to make vapor and leave the vape still over 400F it has to enter the load much hotter than 400F? Convection vapes like Fire Fly, Thermovape products and such have GLOWING HOT sources, that heat air like 1000F and they 'eat up the battery to do it. Llike Fury 2, Solo/Air/ArGo, Fms and their ilk, battery life alone 'proves' it's not really (pure) convection (additional heat losses from the very hot source would prevent this with convection).
That's not to say F2 is straight conduction. It uses the heater that normally heats the load to preheat the incoming air (much like a heat riser in a car). This means the normally cold air is now warm, even hot, and therefore doesn't rob (conduction) heat that would normally be making vapor to heat it up in the load. The total output is therefore more dense. A plus. But the actual work of making vapor is still conduction.
To make convection work the incoming air has to be hotter than the outgoing air so it can give up energy to make vapor. Them's the rules. You can do some good work with preheating (where the heater simply draws more power to keep the load at working temperature) but from a Thermodynamics POV that's not using convection to make vapor. Likewise, radiation needs a huge 'delta' (difference in temperature in degrees) between source and load to work for us. The sun heats the earth only because it's much much hotter and can throw hot photons at us faster that we can throw them back. Ever see a Bender (IR vape from D9)? It's source is incandescent and quite close and IMO doesn't work all that well at that. No way it's going to happen with 400F type temperatures.
Not that the idea isn't popular. Sort of like "Turbo" used to be on PCs? Customers (that means 'guys' like you and me) somehow 'know' convection is better than radiation or conduction. And Customers are always right you know. It's very normal, therefore, to want to have convection? And claiming it can only help sales. But Thermodynamics got there first, with laws that must be followed?
Then again Shakespeare what quite right when he said 'a rose by any other name would smell as sweet'. The proof is in the vapor, and F2 proves it's worth there IMO. I have great hope for Fierce since it's freed of some of the limits on F2 and can/will stand shoulder to shoulder with top end vapes like Solo/Air I hope. No matter how it heats......it's just that I think we should use technical terms correctly?
We'll know very soon, but if this isn't a truly fine machine for making vapor I'll be very very surprised and want to know why!
Regards to all, as we wait out the big day.
