Exo Terra Ceramic Heat Emitter Nano 25W – PT2042 | Vivarium Heat Source

The ET Ceramic Heat Emitter Nano 25W (PT2042) is a compact radiant heat source built for smaller terrariums. Sized specifically for nano and mini setups, it delivers consistent infrared heat around the clock without emitting any light — making it a reliable, non-disruptive heating solution for reptile keepers who need precise ambient temperature control in a confined space.

How It Heats

Rather than warming the air directly, this ceramic emitter produces long-wave infrared heat rays that penetrate deep into skin, muscle, nerves, and bone. This promotes healthy circulation and supports digestion and recovery — the same broad-spectrum warmth reptiles benefit from in natural sunlight, without the visible light component.

24-Hour Heat Without Disruption

Because the ET Ceramic Heat Emitter Nano 25W produces no light output whatsoever, it can run continuously day and night without interfering with your animal's natural activity cycles or photoperiod. It raises overall ambient air temperature steadily, and can also be directed at a specific area to create a defined basking zone and temperature gradient within the enclosure.

Built for Nano and Mini Terrariums

• Designed for use in nano and mini-sized terrariums where standard bulbs are too large
• Compact form factor suited to smaller dome fixtures designed for these enclosures
• Solid ceramic element with 100% heat efficiency — no energy wasted on light production
• Rated at 25W, appropriate for maintaining heat in smaller vivarium volumes

Thermostat Compatibility

As with all ceramic heat emitters, this unit should be used with a thermostat — either an on/off or pulse proportional type. This protects your animal from temperature spikes and extends the lifespan of the emitter. Do not run it uncontrolled.

For keepers running compact setups who need a clean, light-free heat source they can trust around the clock, the ET Ceramic Heat Emitter Nano 25W delivers exactly what it needs to — nothing more, nothing less.
