I tried something like ceramic heaters - small expensive resistors with stable layer. Very small. They work, but usual silicone floss with a nichrome or kanthal wire is much better. Genesis with usual kanthal coil is much-much better. The main reason is liquid supply and its vaporization.

Size and slow heating are negative factors on ceramic heaters but research has shown me there are micro thermostats
the original poster asked if all watts are the same for vapers, he observe that often shorter coils at same wattage as longer coil will have tendency to have burned taste.
some people reply that small parts of the nichrome (or kanthal) wire is more likely to be overheating on shorter coils because nichrome wire resistance does not throttle with temperature, and when more wattage is applied at wire length the likelyhood of nichrome wire vaporizing all nearby liquid, and then carry on to carbonizing vapour instead increases with a higher factor than the wattage/cm increase

the problem he (and pretty much everyone else) is having is that nichrome wire is regionally too hot, but overall temperature might be ok, thermostat will not fix his problem

that said, for me, a thermostat would definately be a welcome addition to atleast mitigate problems if not solve them.
but as nice as overall temperature control would be it would be much nicer if ecig heating element was able to throttle wattage in regions where my precious battery power is applied to burning off my otherwise delicious strawberry bliss.
millions of heating elements are able to throttle like that, it MUST be possible to make atomizer that is equally good

Normally the hot spots are the two legs of the coil going to the posts, this area does not get as wet from the wick. I have been able to eliminate these hot spots by attaching two small pieces of thin silver wire to each end of the kenthal and the first and last wrap of the coil is silver wire with 32awg kenthal in between. No hot spots from the post to the coil. A narrow range differential thermostat similar to what is used on an iron should work if I can find one small enough.

Actually as the original poster I was not referring to hot spots. It was more that 8 watts on 4 wraps is not the same as 8 watts on 8 wraps of the same 32 awg wire. So to me constant watts are not the same as the Darwin people tend to state and that your flavor will always be the same no matter what ohm atty you use or if the resistance changes on your atty as it ages as long as the watts stay constant.

and they would be correct if nichrome wire didnt have bad tendency to make hotspots everywhere, especially when age starts to clog up liquid flow. the points nearby the posts is not the only problem

I just bend small free ends of the heating wire around the legs. They work as a small heatsinks, also increase liquid qiantity in this zone.

Looks good. I like your 8 wraps. Scares me when I see 3 or 4 wraps. I think many are not appreciating true flavor by confusing hot vaper as good TH.
