5 Best Reptile Heating Mats in 2025

Over the years I’ve tried dozens of heat mats under tanks and tubs, and these five stand out. Whether you want efficient heat for a ball python, reliable warmth for a leopard gecko, or safety-first design. Here’s a breakdown of what’s worked best in my setups.

1. Exo Terra Heat Mat

• Size: Medium (~10″×11″), 16 W

• Ultra-thin carbon film

• For glass tanks and substrate heating

Pros

• Excellent heat transfer and even coverage

• Strong, reliable adhesive

• Heats quickly once attached

Cons

• Needs a separate thermostat (no built-in control)

• Not waterproof—avoid wet or high-humidity setups
  

Ideal use: My go-to for ball pythons and gecko tubs where glass-bottom heating is needed.

2. iPower 8×18″ Heat Mat

Why I like it: Perfect balance of good size, adjustability, and affordability. I’ve used this one for bearded dragon nighttime heat.
