Exo Terra Ceramic Heat Emitter Nano 40W PT2043 | Vivarium Heat Source

The ET Ceramic Heat Emitter Nano 40W (PT2043) is a compact, light-free radiant heat source designed for smaller vivariums and terrariums. Running at 40W, it is sized specifically for nano and mini setups where a full-size emitter would be impractical, and it works around the clock without interfering with your animal's natural day and night behaviour.

How It Heats

Rather than warming the air directly, this ceramic emitter produces long-wave infrared heat waves that penetrate deep into skin, muscle, and tissue — closely mimicking the radiant warmth of natural sunlight. This promotes healthy circulation and supports digestion and general physiological function in reptiles and other exotic species. The solid ceramic element converts power to heat with 100% efficiency, producing no wasted light output.

24-Hour Use Without Disruption

Because the emitter produces zero visible light, it can be left on through the night as a continuous heat source without altering your animal's activity patterns or disrupting natural behaviours. It can also be directed at a specific area of the enclosure to establish a basking zone and maintain meaningful temperature gradients across the terrarium.

Designed for Smaller Enclosures

• Compact dimensions suited to nano and mini terrarium formats
• Compatible with the ET Reptile Dome NANO fixture, designed specifically for nano and mini setups
• Raises ambient air temperature effectively within smaller enclosure volumes
• Solid ceramic element — no filament, no glass, robust for long-term use

Thermostat Compatibility

This emitter should always be used with a thermostat. An on/off or pulse proportional thermostat is recommended to maintain accurate temperatures and extend the life of the emitter. Running any ceramic heat source uncontrolled risks overheating and is not good practice.

A reliable, no-nonsense heat source for keepers who need consistent warmth in a compact enclosure without any light output to compromise their animal's environment.
