I don’t have one, but knowing other convection heaters here are a few things to check/try.
1. If you can see the coil, does it look like a fairly even spiral? If it’s not it will be harder to get even heating.
2. A slow draw should heat more evenly. Adjust temps along with draw speed if this negatively affects the amount/quality of vapor.
3. Adding an extra screen above the heater may help.
4. Make sure the settings are good and everything you can clean is clean (screens especially).
5. If nothing else gets it to where you want it, stirring should help, it’s just annoying and can be messy.
I hope something there helps. If not, reading back through the thread may turn up something, and maybe the iHeat/Heat Island threads might help since they’re the source of these heaters.
Good luck!
@kenske Sorry to hear another story like this...I hope it gets resolved, and I’m pretty sure
@Bravesst intended to make things right, but I’ve been feeling for a while now that something’s changed for the worse over there and it worries me.
I hope things get back on track for him and all of you so I’ll feel comfortable including these in lists of quality convection portables again. Good luck on both sides, I hope things get worked out to everyone’s satisfaction.
