3 . To Reduce Moisture

Unheated garages are prone to moisture buildup, especially during the winter months. This can cause damage to your belongings, such as rust on metal tools or mold on wooden furniture. Installing a garage heater can help reduce moisture levels and prevent any potential damage.

How to Install a Garage Heater in 6 Easy Steps

Step 1: Ensure You Have All the Necessary Tools and Materials

Before beginning the installation process, it is important to ensure that you have all the necessary tools and materials. This will save you a lot of time and hassle during the installation process.

Some of the essential tools you will need include a drill, screwdriver, level, tape measure, and adjustable wrench. Additionally, make sure you have the appropriate type and amount of insulation, wiring, and ductwork for your specific heater.

Step 2: Choose the Right Location

Choosing the right location for your garage heater is crucial for ensuring its effectiveness. The best location will depend on the size and layout of your garage. Generally, a corner wall or ceiling mount near an electrical outlet is ideal.

Make sure to also consider any potential obstructions or hazards, such as shelving units or flammable materials.

Step 3: Install the Vent

Proper ventilation is essential for safely and effectively operating your garage heater. Begin by cutting a hole in the wall or ceiling where you plan to install the vent. Then, attach the vent hood to the outside of the hole using screws and seal any gaps with caulk.

Next, attach the vent pipe to the hood and secure it in place using screws or metal tape.

Step 4: Mount the Heater

Once your vent is properly installed, it’s time to mount the heater itself. Follow the manufacturer’s instructions for assembling and mounting the unit. Typically, this involves attaching brackets to the back of the heater and securing them to the wall or ceiling using screws. Use a level to ensure that the heater is installed straight.

Step 5: Connect the Wiring

Before connecting any wiring, make sure to turn off the power to your garage at the main circuit breaker. Then, connect the wiring from your electrical panel to the heater according to your manufacturer’s instructions.

It’s always a good idea to have a professional electrician assist with this step if you are not confident in your wiring abilities.

Step 6: Test and Adjust

After completing the installation, it’s important to test the heater before using it regularly. Turn on the power at your circuit breaker and adjust the thermostat according to your preferences. Also, make sure that warm air is being properly distributed through your garage. If adjustments are needed, refer to the manufacturer’s instructions for troubleshooting tips.

Some Extra Tips to Install a Garage Heater

1 . Do Not Ignore the Manufacturer’s Instructions

Installing a garage heater may seem like an easy task, but it is always important to follow the instructions provided by the manufacturer. Every heater model has its own specifications and requirements for installation, so make sure to read and understand them before starting the process. Ignoring these instructions can lead to incorrect installation and potential safety hazards.

2 . Choose the Right Location for the Heater

When installing a garage heater, it is crucial to choose the right location. The heater should be placed in an area with good air circulation and away from any flammable materials. It should also be at least 18 inches above the ground to prevent any potential hazards.

3 . Ensure Proper Ventilation

Proper ventilation is key when installing a garage heater. It is important to have a way for the toxic fumes produced by the heater to escape, as they can be harmful if trapped inside the garage. This can be achieved by installing vents or using windows or doors in the garage.

4 . Have Proper Electrical Connections

Before installing a garage heater, make sure to check your electrical connections. The heater should be connected to a dedicated circuit with the appropriate voltage and amperage. It is also important to have a licensed electrician check and approve the electrical connections before use.

6 . Consider Professional Installation

While it is possible to install a garage heater on your own, it may be best to consider professional installation. This is especially true for larger or more complex heaters. A professional installer will have the necessary expertise and tools to ensure proper installation and safety.
