How to Prime a Vape Coil Properly (Step-by-Step UK Guide)

If you’ve ever installed a new vape coil and immediately experienced a burnt taste, the coil likely wasn’t primed correctly.

Learning how to prime a vape coil properly is essential for:

• Preventing burnt hits
• Extending coil lifespan
• Improving flavour
• Saving money on replacements

Priming is especially important for refillable pod kits and MTL devices commonly used in the UK.

If you're new to vaping, start with our guide on how to choose the right pod kit for MTL vaping to make sure you're using the correct device.

What Does Priming a Vape Coil Mean?

Priming a coil means saturating the cotton inside the coil with e-liquid before using it.

Inside every vape coil is:

• Organic cotton
• A heating element
• Wicking ports

If the cotton is dry when heated, it burns instantly. Once burnt, the coil cannot be fixed.

If you’re unsure when you should replace your coil, read our guide on how long vape coils last in the UK.

Step-by-Step: How to Prime a Vape Coil Properly

Step 1: Add E-Liquid Directly to the Coil

Before installing the coil, drip a few drops of e-liquid directly onto the exposed cotton inside the coil.

This helps pre-saturate the wick before it heats up for the first time.

Step 2: Install the Coil Into the Pod or Tank

Insert the coil firmly into your pod or tank. Make sure it fits correctly to prevent leaking.

Step 3: Fill the Pod or Tank

Fill your pod or tank with your chosen e-liquid.

Nicotine salts are ideal for most UK pod kits as they provide smoother throat hits and better absorption in low-powered devices.

Choosing the correct e-liquid strength also matters, so read our guide on best nicotine strength for pod kits in the UK.

Step 4: Wait 5–10 Minutes

This is the most important step.

After filling your pod, wait at least 5–10 minutes to allow the e-liquid to fully soak into the cotton.

Rushing this step is the number one reason coils burn out early.

Step 5: Take Gentle Primer Puffs

If your device allows it, take a few gentle draws without pressing the fire button. This helps pull more e-liquid into the coil.

Why Your Vape Still Tastes Burnt

If your vape still tastes burnt after priming, it could be due to:

• Chain vaping too quickly
• Using the wrong e-liquid ratio
• Faulty or incompatible coils
• Not allowing enough time to soak

If your coil is already damaged, explore our guide to the best replacement pods and coils in the UK to find compatible parts.

How Long Should a Properly Primed Coil Last?

With correct priming, most vape coils last:

• 1–2 weeks for moderate users
• 5–10 days for heavy users

Device quality also plays a major role in coil lifespan.

Using a reliable device can improve performance, so see our guide on the best refillable pod kits in the UK.

Common Coil Priming Mistakes to Avoid

Avoid these common mistakes:

• Not waiting long enough after filling
• Using high VG e-liquid in small pod kits
• Vaping at wattages higher than recommended
• Ignoring early signs of coil wear

If you’re just starting out, using a beginner-friendly device makes maintenance much easier.
