In this up-to-date UK-focused guide, we'll break down everything you need to know about vape tanks: what they are, how they work, the different types available, how to choose the right one, and how to maintain them properly. We'll also reference popular UK-friendly options and compatible products available from EcoSmok.
What Is a Vape Tank?
A vape tank is the component of a vape device that holds your e-liquid and houses the coil that heats it into vapour. Vape tanks sit on top of vape mods or compatible batteries using a standard 510 connection, making them interchangeable across many devices.
Simply put, your vape tank is where the magic happens. E-liquid is absorbed into the cotton wick inside the coil. When you activate your device, the battery sends power to the coil, heating the liquid and turning it into vapour that you inhale through the mouthpiece.
Vape tanks are commonly used with box mods and advanced vape kits, but they can also work with pen-style devices and some refillable pod systems. If you're transitioning from smoking and searching for the best vape for quitting smoking UK, selecting the right tank is just as important as choosing the right nicotine strength.
Main Parts of a Vape Tank
Most vape tanks consist of several key parts, each playing an important role in performance, flavour, and leak prevention.
- Drip Tip (Mouthpiece): The part you inhale through. Common sizes include 510, 810, and wide-bore tips.
- Top Cap: Seals the tank and gives access to the filling port.
- Glass Tank: Holds the e-liquid and lets you see your juice level.
- Coil: The heating element made of wire and cotton that vaporises e-liquid.
- O-Rings: Rubber seals that prevent leaking between parts.
- Base: Houses the airflow control and 510 connection.
How Vape Tanks Work
Vape tanks work by combining airflow, power, and wicking. When you inhale or press the fire button, the battery sends power to the coil. The coil heats up, vaporising the e-liquid soaked in the cotton wick. Airflow holes allow air to mix with the vapour, cooling it and delivering flavour smoothly.
This balance between airflow, coil resistance, and e-liquid viscosity determines whether a tank is suitable for mouth-to-lung (MTL) or direct-to-lung (DTL) vaping.
Compatible with all major kits
Shop Coils βMouth-To-Lung (MTL) Vape Tanks
MTL tanks are ideal for beginners, ex-smokers, and anyone looking for the best vape for heavy smokers UK. They mimic the draw of a cigarette and work best with higher nicotine strengths or nic salts.
- Tight airflow
- Higher resistance coils (0.8Ξ© β 1.8Ξ©)
- Lower wattage (10β20W)
- Compatible with 50/50 e-liquids and nic salts
Sub-Ohm (DTL) Vape Tanks
Sub-ohm tanks are designed for direct-to-lung vaping and cloud production. These tanks use low-resistance coils and high VG e-liquids.
- Airy airflow
- Low resistance coils (below 1.0Ξ©)
- Higher wattage (40W+)
- Best used with high VG e-liquids
Rebuildable Vape Tanks (RTA & RDTA)
Rebuildable tanks are for advanced users who want complete control over their vaping experience. You build your own coils and wicks, allowing for customised resistance, airflow, and flavour.
These tanks require knowledge of Ohm's law and battery safety and are not recommended for beginners.
Choosing the Right Vape Tank
To choose the right vape tank, consider the following:
- Your vaping style (MTL vs DTL)
- Nicotine strength preference
- E-liquid VG/PG ratio
- Ease of use and maintenance
- Coil availability and cost
Beginners should focus on simplicity and reliability. Pairing a quality tank with a starter kit from EcoSmok vape kits ensures compatibility and ease of use.
Tank Capacity and UK TPD Rules
In the UK, vape tanks are limited to a maximum capacity of 2ml under TPD regulations. While this means more frequent refilling, it ensures legal compliance and safety.
Heavy vapers may prefer carrying spare e-liquid or choosing tanks with efficient coils to reduce refill frequency.
Top-Fill vs Bottom-Fill Tanks
Modern vape tanks mostly feature top-fill designs, allowing quick and mess-free refilling. Bottom-fill tanks are older designs and less common in 2025.
Maintaining Your Vape Tank
Proper maintenance extends coil life, improves flavour, and prevents leaks.
- Clean your tank weekly with warm water
- Replace coils every 1β3 weeks
- Check and replace worn O-rings
- Use the correct e-liquid for your tank type
Replacement coils are easy to find, including Vaporesso Corex 3.0 pods and OXVA Xlim V3 pods.
Common Vape Tank Problems
- Leaking: Caused by worn seals, wrong e-liquid, or poor coil installation
- Burnt Taste: Dry or expired coil
- Gurgling: Excess liquid in the airflow chamber
Most issues are easy to fix with proper setup and maintenance.
Kits + coils + e-liquid = savings
