A thermostat is one of the most important safety tools in a reptile enclosure. It controls heat sources so temperatures don’t climb too high. The Inkbird ITC-308 and Herpstat thermostats are two popular options. They work in very different ways and at very different prices. This comparison helps you decide which suits your setup.
The Short Answer: The Inkbird ITC-308 is an affordable on/off thermostat that works well with non-light heat sources such as heat mats and ceramic heat emitters. Herpstat thermostats cost more but offer proportional and dimming control, alarms and multiple outputs. Your choice depends on your heat source and budget.
Key Details
| Feature | Details |
|---|---|
| Inkbird ITC-308 | On/off control; heating and cooling outlets |
| Herpstat | Proportional, pulse and dimming modes (varies by model) |
| Price | Inkbird is low cost; Herpstat is higher |
| Best with | Inkbird: heat mats, ceramic emitters; Herpstat: most heat sources |
| Alarms | Herpstat offers more advanced alarms |
What It Is and How It Works
On/off thermostats switch the heat source fully on or fully off. This works for heat sources that don’t produce light. With heat bulbs, on/off switching causes lights to flicker on and off, which can stress reptiles and shorten bulb life.
Dimming thermostats adjust the power to keep temperatures steady. They work well with heat lamps. Proportional thermostats provide smoother control.
The Inkbird ITC-308 is a general-purpose thermostat that isn’t specific to reptiles. Herpstat thermostats are designed for reptiles and offer more modes and safety features.

Match the thermostat to your heat source.
Things to Consider Before Buying
- Identify your heat source.
- Check wattage limits.
- Secure the probe properly.
- Use a separate thermometer to verify temperatures.
- Consider alarms for high-risk setups.
Who It Suits
| Good fit if… | Consider something else if… |
|---|---|
| Inkbird: heat mats, ceramic emitters, budget setups | Inkbird: heat lamps that emit light |
| Herpstat: heat lamps, larger or multi-zone setups | Herpstat: very simple budget setups |
Alternatives to Consider
| Option | How it differs |
|---|---|
| Vivarium Electronics thermostats | Another reptile-specific option |
| Habistat dimming thermostat | Dimming control at mid-range price |
| Zoo Med ReptiTemp | Simple on/off or rheostat options |
When to Call Your Vet
Contact your vet if:
- Your reptile has burns
- Your reptile is lethargic or not eating
- You suspect overheating
Frequently Asked Questions
Can I use the Inkbird ITC-308 with a heat lamp?
It works, but on/off switching makes the light flicker. A dimming thermostat is usually better for lamps.
Is a Herpstat worth the price?
Many keepers find the safety features and smooth control worth it, especially for larger setups.
What’s the difference between on/off and dimming?
On/off switches heat fully on or off. Dimming adjusts power to maintain temperature.
Where should the probe go?
Usually at the basking or warm surface area. Follow the manufacturer’s guidance.
Do I need a thermometer if I have a thermostat?
Yes. Verify temperatures with a separate thermometer or temperature gun.
Can one thermostat control multiple heat sources?
Some models have multiple outputs. Check wattage limits.
What happens if a thermostat fails?
Temperatures can rise or fall dangerously. Alarms and regular checks help.
Is the Inkbird safe for reptiles?
It’s widely used. Make sure the probe is secure and wattage is within limits.
What is a pulse proportional thermostat?
A pulse proportional thermostat sends power in rapid bursts to non-light heat sources. This keeps temperatures steadier than simple on/off control. It shouldn’t be used with light-emitting bulbs.
Can I use the Inkbird ITC-308 with a heat mat?
Yes. Heat mats are a common use for on/off thermostats like the ITC-308. Secure the probe on the surface above the mat and check temperatures with a separate thermometer.
Do Herpstat thermostats have alarms?
Many Herpstat models include high and low temperature alarms and safety features that cut power if a probe fails. Check the current model’s features before buying.
