Temperature Controlled Outlet for Heater Plug - Auto On 38 F/Off 50 F

In this review of the YeloDeer 2 PCS upgraded thermostat outlet for greenhouse and well house heater, the bottom line is simple: it is a low-cost, no-fuss solution for automatically powering small 120 V heaters and de-icers when temperatures fall. Designed to switch on below 38 F and off above 50 F, this plug-in thermostat is aimed at farmers, RV owners, and homeowners who need a hands-off way to protect pipes, ponds, and animal waterers from freezing. Installation is instant - just plug it into a standard 15 Amp outdoor outlet and connect a heater - and the unit is built from durable ABS and PC to tolerate cold conditions.

Key Features

• Automatic temperature control: Activates the connected heater below 38 F and deactivates above 50 F so devices run only when needed.
• Plug-and-play setup: Requires no wiring or programming, offering a quick installation into any 15 Amp outdoor receptacle.
• 120 V compatibility: Works with standard 120 V electrical heaters, de-icers, and heating tapes for broad device support.
• Cold-tolerant construction: Molded from high-grade ABS and PC to provide reliable performance in harsh, cold environments.
• Labor and energy saving: Automatically limits runtime to colder periods, reducing manual monitoring and unnecessary power use.
• Versatile applications: Suitable for greenhouse heaters, pond de-icers, chicken coop heaters, water pipe heat tape, and RV needs.

Who It's For

This thermostat outlet is best for people who want a simple, economical way to protect outdoor systems from freezing without running dedicated thermostats or hardwired controls. It suits small farms, hobbyist greenhouse owners, pond keepers with de-icers, and RV or well house operators who use small 120 V heating devices.

It may be less suitable for those who need precise digital temperature control, programmable schedules, or higher current capacity; professionals requiring hardwired HVAC controls or devices above 15 Amps should look at wired thermostats or commercial controllers.

Pros & Cons

Pros

• Automatic on/off at set temperatures eliminates frequent manual checks and reduces freeze risk.
