Comprehensive Guide: How to Bypass Thermostat on an Infrared Space Heater

Bypassing the thermostat on an infrared space heater can be a useful solution for those who want to have more control over the heating output of their device. However, it’s crucial to understand the risks involved and follow proper safety precautions. This comprehensive guide will walk you through the step-by-step process of bypassing the thermostat on an infrared space heater, along with detailed technical specifications and safety considerations.

Safety Precautions

Before attempting to bypass the thermostat, it’s essential to prioritize safety. Infrared space heaters operate on high voltages, typically 120V or 240V, and can pose serious electrical hazards if not handled properly. Always ensure that the space heater is unplugged from the power source and has cooled down completely before starting any work.

Accessing the Electrical Components

how to bypass thermostat on an Infrared Space heater

  1. Locate the Back Panel: Using a screwdriver, remove the back panel of the infrared space heater to expose the internal components, including the fan, control panel, and the shut-off switch (sensor).

  2. Identify the Shut-off Switch (Sensor): Locate the sensor that is responsible for shutting off the heater when it is tipped or knocked over. This sensor will have wires connected to it.

Bypassing the Shut-off Switch (Sensor)

  1. Cut the Wires: Using wire strippers, carefully cut the wires going to the shut-off switch (sensor).

  2. Strip the Wire Ends: Strip the ends of the cut wires, exposing the copper conductors.

  3. Twist the Wires Together: Twist the stripped wire ends together to create a secure connection.

  4. Secure the Connection: Twist a wire nut over the connected wire ends to ensure a reliable and safe connection.

Reassembling the Space Heater

  1. Replace the Back Panel: Carefully replace the back panel of the infrared space heater, ensuring that all the components are properly aligned and secured.

  2. Position the Heater: Place the heater on the floor in an upright position.

  3. Plug in the Heater: Plug the infrared space heater back into the power source.

Testing the Bypassed Heater

  1. Set the Heat Setting: Set the heater to a low to medium heat setting.

  2. Turn on the Heater: Turn on the infrared space heater and observe its operation.

  3. Monitor for Issues: Closely monitor the heater for any signs of overheating, unusual noises, or other potential issues.

Technical Specifications

  • Voltage: Infrared space heaters typically operate on 120V or 240V.
  • Wattage: The wattage of infrared space heaters can vary, but they typically range from 750W to 1500W.
  • Thermostat: The thermostat is responsible for regulating the temperature of the heater. Bypassing the thermostat will result in the heater operating at full power until it is manually turned off.

DIY Perspective

Bypassing the thermostat on an infrared space heater can be a DIY project for those who are experienced in electrical work. However, it’s crucial to prioritize safety and consult with a professional if you are unsure about any step in the process. Always follow the manufacturer’s instructions and safety guidelines when working with electrical appliances.
