Spaced or Touching single coil using Kanthal wire (non-sub ohm) ?

[Flt Simulation]

Got a question for you folks ...

I have been making a simple single 28 AWG Kanthal coil in the 1.3 - 1.4 ohm range for my Kayfun Lite-Plus for quite a long time now. I have always made the coil so it was all touching, since that was what most of the YouTube coil build videos normally showed.

However, now I start seeing people using spaced coils using Kanthal.

I understand that spaced coils are recommended for Ni200 or Ti coils (temp control mode), but do your standard Kanthal coils benefit from a spaced coil too?

Is a spaced single Kanthal coil now the new norm for non-temp controlled vaping?

Thanks,

No, touching or contact coils are the go-to for kanthal, nichrome, stainless because it creates more heat.Spaced coils for Ti or Ni200 are strictly because you cant glow Ti or Ni because it can make toxic oxides that are bad to inhale and spaced coils tend to glow evenly without squeezing. You can glow and squeeze the other metals safely

Just like you Fit I use the same wire set up in my Kayfuns and Reo on a daily basis. I've tried the spaced coil thing and all I can say is "Meh". Either way they both taste and fire the same to me. I just keep making the touching coils just because it's muscle memory.

I've always used spaced coils, because it doesn't concentrate the heat so much; when I was first learning to wick, that was important to me, to avoid burnt hits, and I just got used to it -- to me, more heat is not a good thing; I want the vape just barely warm, so it doesn't play hell with my lips.

Fit, nothing but spaced in my Kayfun's. I run at .8 using 26ga though but the flavor and wicking seem better to me since I made the switch. The only time I use a contact these days is if the atty has space constraints.

When I was vaping before I used a spaced coil. When I started vaping again, I saw someone using ceramic tweezers to make touching coils. I started using touching coils to save room for an in-line dual coil setup. It seams to work fine. Plus I would not be able to fit the coils in there if they were spaced. (using two 30 gauge Kanthal 3 ohm coils to make a 1.5 ohm kayfun 4 tank atty) I did use a right hand wind and a left hand wind so that the positive ends would be next to each other to prevent potential shorting.

Walk into any vape shop in anywhere USA and ask the workers to see their builds in the atty they are vaping. 99.995% will be compressed coils. I find spaced coils to give off a raspy vape. I only use them in Ti builds.

You could always try both. All of my RTAs have contact coil wraps due to the deck size, most of my RDAs have contacts too. The Phenotype-L, which has a two post design, is running spaced coils because the deck can handle it. I also get much shorter legs since the coil spans from post to post. It's such a good vape it's the only RDA I have wicked, the rest I set aside.

The Kayfun can do both with no issues though.

so far in my limited experience my choice is based on geometry.
I want my coil legs to line up neatly so that I don't have kinks or long legs (especially to the positive post) so as to avoid hotspots/hotlegs.

I just made a coil today for the rda that came with my terminator squonk box, and I handwound it spaced because there was a lot of room for it to fit in;

If I wrap a coild for one of my subtank rba decks, however, I would wind it compact on a coiler so that the legs will line up neatly with were they have to get screwed down in that small space.

Spaced in KFL v2 lite because I can go 2 weeks without a rewick.


they dont gunk up as bad as the contacts coils for some reason.

Thanks for your feedback ...

Looks like everyone here is pretty much split between contact or spaced coils.

As I said before, I always make a contact coil, but I certainly going to try a spaced single coil next time around just to see if I can tell the difference in the vape quality.

I prefer spaced coils, because they stay gunk free, longer, for me. Less rewicking, 2 days vs less than 1. I also think I get a little more flavor from a spaced coil. Next since, I mostly use twisted wire. Making a contact coil is next to impossible, there are always lots of holes and the wire just overlaps itself.

Spaced coils needs more power to obtain the same result/heat, but also will wick better in a rta/tank, especially high-vg liquids and not give as much problems with dry puffs and you can take longer hits before getting dried out wick. To me the taste of spaced coils are better. I don't know why, but i'm theorizing that it's because you get twice the surface area in a way... What I mean is that the spaces in between the wraps also gets hot and can vaporize liquid from the wick, effectually doubling your wrap-count... Maybe it's not because of that, but some other phenomena, but whatever, I can taste a difference.

However, i'm just using contact coils also, as I like they heat up faster, requires less power so gives better battery life, and is easier for me to make and also dryburn and wick later... Second I use unflavored so isn't a flavor chaser...

Spacing does NOT, require more power. wire diameter and amount of wire determine that. Or even affect the heat of the coil or speed heating of coil. It does however spread the heat available, over a greater area. A contact coil will burn off the juice inside the coil faster, if only because it has a smaller amount of juice IN the coil.

As contact coils increase the efficiency of power delivery, I think it's not wrong to say that they do need less power...

More concentrated heat generated, equals increased juice evaporation...

They only increase the efficiency of HEAT delivery, due to concentration. There is no POWER (electrical) difference.

So yes you are partially correct. Just confusing electrical properties with HEAT delivery properties.

 

[mhertz]

Sorry, but i'm not partially correct... I stated, increases the _effeciency_ of _power delivery_, not more power delevery...

POWER refers to an electrical property NOT heat. That's where the partial comes in. A 1 ohm coil of 28awg, will delivery/draw the same amount of POWER regardless of spacing, coil ID or wraps. BUT changes in those factor, spacing,/id/wraps, will change the concentration of the resulting heat.

 

[mhertz]

Sorry, I do know you know your stuff, but I haven't stated anything of the sort you're mentioning and fully agree with you

I also like spaced better. Like others have said, it gunks less. I also started with contact coils because of tutorials but once I started using spaced I won't be going back.
