Next, you need to run electrical wiring from the panel to the garage where the heater will be installed. Choose a wire gauge that matches the heater’s requirements and local electrical codes.
For most heaters, 10-gauge wire is commonly used for a 30-amp circuit, but always verify with your heater’s specifications. Drill holes through the walls or ceilings as necessary to route the wires, and use electrical conduit or cable protectors to safeguard the wiring along its path. Ensure that the wiring is securely fastened and protected to prevent damage.
5. Install an Electrical Junction Box
An electrical junction box provides a safe and accessible location for connecting the heater’s wiring to the circuit. Install the junction box in a convenient location near the heater, ensuring that it is easily accessible for future maintenance.
Mount the box securely to the wall or ceiling and ensure that it is level. Use a box that is appropriately sized for the amount of wiring and connections it will house. This step ensures that all electrical connections are safely contained and protected.
6. Connect the Heater to the Wiring
With the junction box in place, you can now connect the heater to the electrical wiring. Strip the ends of the wires to expose the conductors and connect them to the heater’s terminals according to the manufacturer’s wiring diagram.
Typically, you will connect the hot wires (usually black or red) to the heater’s hot terminals, the neutral wire (usually white) to the neutral terminal, and the ground wire (usually green or bare) to the ground terminal. Use wire connectors and electrical tape to secure the connections and ensure that there are no exposed wires.
7. Install a Heater Switch or Thermostat
For convenience and control, you may want to install a switch or thermostat to manage the heater’s operation. Choose a location that is easily accessible and away from any sources of heat or moisture.
Install the switch or thermostat according to the manufacturer’s instructions, connecting it to the wiring that leads to the heater. If installing a thermostat, ensure it is compatible with your heater and correctly wired to control the heater’s temperature settings. This addition provides an easy way to regulate the heater and enhance its functionality.
8. Secure and Insulate Wiring
Properly securing and insulating wiring is crucial for safety and performance. Use cable clamps or staples to secure the wiring to walls, studs, or ceilings, ensuring that it is protected from damage.
Insulate any exposed wires or connections with electrical tape or heat shrink tubing. Make sure that all wiring is neatly organized and free from any kinks or sharp bends. Proper insulation helps prevent electrical hazards and ensures that the heater operates efficiently.
9. Test the Heater and Electrical System
Before using the heater, it’s important to test the entire electrical system to ensure that everything is functioning correctly. Turn on the main power to the panel and switch on the new circuit breaker.
Check the junction box and wiring connections for any signs of issues, such as sparks or overheating. Test the heater by following the manufacturer’s instructions and verify that it heats up properly and responds to the thermostat or switch. This testing ensures that the installation is complete and that the heater is safe to use.
10. Complete Final Inspections and Clean Up
After confirming that the heater is working correctly, complete any final inspections and clean up the work area. Inspect the installation for any signs of loose wires or other issues that may need addressing. Ensure that all covers, plates, and junction boxes are securely installed and that there are no exposed wires.
Clean up any debris or tools left from the installation process and ensure that the garage is in its original condition. Completing these final steps ensures that your hardwired garage heater is installed safely and ready for use.
