Our Verdict

This is a replacement thermostat, not a standalone heater. It works only with Mr. Heater's 50,000 BTU portable kerosene forced air heaters.

The thermostat lets you set a target temperature from -23C to 100F. Your heater cycles on and off to hold that temperature automatically.

It runs on AC power. That makes it dependable and consistent during long work sessions in garages or on job sites.

At $46.69, this part costs a fair price for a manufacturer-matched replacement. Generic thermostats may not fit or function correctly.

This part does not add tip-over or overheat protection. Your safety depends on the heater unit itself, not this thermostat.

Standout Features

50,000 BTU compatibility

Most electric space heaters max out at 5,118 BTU (1,500W). This thermostat works with a unit delivering nearly 10x that output, making it suitable for large uninsulated spaces.

Temperature range: -23C to 100F

Most residential thermostats cover a narrow 60F to 90F range. This unit handles sub-freezing outdoor and workshop conditions that standard thermostats cannot reach.

AC-powered thermostat operation

Battery-powered thermostats require periodic replacement. This AC-powered unit delivers uninterrupted operation during extended heating sessions without battery concerns.
