About This
- [CSA Certified for Safety] The entire product is CSA certified, ensuring high safety and quality standards. It provides reliable performance and peace of mind for various heating applications.
- [Smart Thermostat with Indicator Light] Equipped with an intelligent indicator light, the thermostat-controlled outlet powers on when the temperature drops below 38℉ (3℃), and the light turns on. It automatically shuts off around 50℉ (10℃), optimizing energy usage.
- [Energy-Saving & Easy to Use] The plug-and-play design allows for effortless operation—simply plug the device into a power outlet, and it will automatically turn on or off based on the ambient temperature. This energy-efficient feature helps reduce electricity costs.
- [Versatile Applications] With a maximum capacity of 15A, this thermostat outlet is ideal for 120V AC electric heaters, gas heaters, engine block heaters, pipe heating cables, roof de-icing cables, and more. Designed for dry locations only.
- [Simple Testing & Warranty] To test the product, place it in a refrigerator for 45 minutes, then plug it into a power source—you will see the red indicator light on the thermostat controller. Backed by a two-year limited warranty. If you are not fully satisfied with the HEATIT ET-21, contact us, and we will do our best to resolve any issues.

Many devices still work manually or through local control.
You may lose remote app access, but locks, lights, and thermostats often continue basic functions.
Security depends on the device and setup.
Use strong passwords, trusted brands, firmware updates, and secure Wi-Fi for better protection. Privacy and unauthorized access are common concerns in smart homes.
