Welcome to ECF llov3Yuri 
Coils heat up to vaporize the liquid, as they get hot they will transfer the heat to the tank, you could try turning down the wattage.

Welcome to ECF llov3Yuri
ok, but there r someone telling me to increase the wattage because mine is 0.2 ohm Occ. Now I am confuse.....
Due to the low resistance you need to tune down the wattage for less heat production if it bothers you. But this could be just the nature of the product. Some tanks get hotter than others.
what is the ipv telling you about the ohms ?
maybe one of the coils is dead and the remaining one is getting too hot.
I have heard of the tfv4 gets hotter than other tank models but then its hard to say as how hot is hot? At 21watts its pretty low for a .2 coil build. Are you getting warm draws? I vape at .21ohms at 60watts and my zeph does get hot but not soo hot till i get worried.
Ok, I read some review from other website. They said the d2 doesn't have the step down function, so if tune down the wattage also it will be running at high wattage, is it real? Or I misunderstanding something ?
This is the comment they gave me

Not exactly. The problem is the coil you are using. The iPV has no "step down" ability, which means that you won't be able to set it 21W with a 0.2 coil. It's because the voltage of a fully charged battery is 4.2V. And 4.2V with a 0.2 resistance means that your iPV D2 performs at 75W (88.2W in theory, but it is limited to 75W).
Go here: Ohm's law | Steam Engine | free vaping calculators.
Now lock the "Power" setting and enter 21W in the field. Set the "Voltage" setting to 4.2V and boom. It tells you that you need a 0.84 coil to produce 21W on the iPV D2 with a fully charged battery.
This behavior is only found in mods that have no "step down" ability (and mechanical mods). Most mods have this ability, but the iPV D2 doesn't.
As others have said, you can use TC mode to bypass this behavior because TC mode has the "step down" ability. I don't own an iPV D2 so I can't guide you through it. But, if you look at the top comment, you will see that you have to put the iPV D2 in TC mode and set your temperature to 500°F. Then, you will be able to adjust your wattage to 21W and it will perform at 21W. Temperature control won't work though because... Kanthal. But it'll work if you want to vape from 1 to 50W with Kanthal."
Just after 3 or 4 puffs, it just become hot till I can't touch the bottom part of the tank.
From which site is this? I dont understand any of it. Any vets to clarify please? If i am not mistaken, The TC mode is a variable mode on its own. Its not like u can set the TC and use Power mode together. TC is TC by itself, power is power by itself.
IPVD2 is a single battery mod, 75watts if on a .2ohm u'll get about 3.8volts.. Ur stressing the battery at 19-20Amps!
Ipvd2 is also a regulated mod not a mech mod.
I dunno, i am confused as you are. My advice, wait for the veterans on ECF to answer. I dont trust other sites.
Well if u say ur occ is at .2ohms and ur firing at 21watts that is low and safe..
Its about 2.2volts at around 10Amps kicking.. So your fine at this range.. Even if u go up to 40watts you are fine... 60watts above i dont recommend unless u get new batteries that can fire 30A...
Ok, now i understand.
Fiuh...
Your IPVD2 is a confusing mod. Go under TC mode and select Ni200 (nickel) and set max temp at 110c and vape from 30J.. Keep going up or down when you feel is right...
The mod doesnt go low wattage. Since your ohm is low. Try that and let me know..
As you adjust the J eg; 30J, look at the volts meter, when it hits about 2.7-3.00volts you should be ok..
I tried and it worked!
But it is still getting hot after few puffs, maybe it is normal?
Now I notice the lower the J lesser the vapor come out, then I maximize to 50J the amount of vapor still not that much and it burn my juice like crazy!
I added 1/4 tank, I finish it in just 5 puffs....
Yes, ur using .2ohms so it will go hot because it needs more power and the coils are bigger so the heat is powerful. I hope the juice doesnt burn, if it burns try to lower the temperature to 110 or 105
I have the tfv4 also and I am experiencing the same thing. I am running the stock triple coil on an Istick 50w between 40-50 watts. I also run it on a Smok Xpro M80 plus from 40 - 80 watts. After several puffs the base gets really hot. I understand that heat will transfer but no other tank I have used gets this hot. I have a feeling there might be an issue with the coil as stated by edyne.
I have not tested this yet. My Istick is reading the coil @.3 ohms and the Smok is reading the coil @.19-.20 ohms. I thought this was kinda strange. I know the Istick does not have 2 decimal points and has to round the reading but this is kinda extreme difference. My batteries are not getting hot just the base of the TFV4. I was also wondering if the issue could be running the coils on the low power range but I do not have a mod that will go above 80 watts. One other note is how are you running these coils at 21W? the range of the triple coil is 40 -140 w and when I try to run at 30 I barely get any vapor production. even at 40 watts it takes a bit to start getting vapor.
I was wondering if anyone with a higher power mod has checked this at low watts vs high watts to see if heating is from low watts.
