Electrical Question: How can I wire a thermostat to keep an area at 70 degrees?
- I have a well insulated 8 x 3 x 3 ft enclosure with lid I need to heat for exotic reptiles.
- It is in my barn where I have no heat but I do have 110 electrical outlets ran.
- I need it to stay at 70 degrees F inside the enclosure at all times.
- I have several space heaters but none are programmable to stay at a specific temperature.
- How can I wire a thermostat or something to keep this area at 70 degrees at all times?
- Do I wire a thermostat to an outlet or what?

How to Install a Thermostat Controlled Heating Unit
Application: Wiring a Thermostat to Control a Heating Unit. Skill Level: Beginner to Intermediate – Best if wired by a Licensed Electrical Contractor. Tools Required: Basic Electrical Hand Tools including a small screw driver and small wire strippers. Estimated Time: Depends on personal level experience and ability to work with tools and the small thermostat wires. Precaution: Identify the circuit for the heating unit, turn it OFF and Tag it with a Note before working with the thermostat wiring. Troubleshooting and Testing: Most thermostats may be tested using a Volt/Ohm Meter. The thermostat battery should be tested and replaced as needed. Notice: Make sure to get the exact replacement thermostat or or one that is a compatible replacement, such as a fully programmable thermostat.
Installing a Thermostat Controlled Heating Unit
There are several ways to set up a system to control the temperature for your reptile heater, or any other application as well. The following is an example of how a thermostat may be wired to control a heating unit to maintain 70 degrees.
- To control the temperature of a confined area the key will be to safely install the thermostat at the reptile enclosure and prevent any problems with the reptiles and the room occupants.
- For this application you may consider a low voltage thermostat that is connected to a control relay which would then control the 120 volt power to the heat source.
- Keep in mind that a thermostat is simply a switch that is set to maintain a desired temperature.
- All thermostats are not alike, so be sure to select one that is compatible with the heating unit that is being used, and the same electrical ratings for voltage and amperage.
