What To Know

  • If your heater has a built-in thermostat, connect the thermostat to the heater’s terminals according to the manufacturer’s instructions.
  • Generally, a 1,500-watt heater is sufficient for a small garage (up to 200 square feet), while larger garages may require a 2,500-watt or 3,000-watt heater.
  • While it is possible to install the heater yourself, it is recommended to consult a qualified electrician if you have limited electrical knowledge or experience.

In the chilly winter months, a warm garage can be a sanctuary for your vehicles, hobbies, and projects. An electric garage heater offers an efficient and cost-effective way to keep your garage at a comfortable temperature. Installing it yourself is a straightforward process that can be completed in a few hours with the right tools and materials.

Safety Precautions

Before beginning any electrical work, ensure your safety by following these precautions:

Step-by-Step Installation Instructions

1. Choose the Heater Location

Select a location for the heater that allows for proper air circulation and avoids obstructions. Consider the height and angle of the heater for optimal heat distribution.

2. Mount the Brackets

Attach the mounting brackets to the wall or ceiling using the provided screws. Use a level to ensure the brackets are level and securely fastened.

6. Turn on the Power

Restore power to the garage at the circuit breaker or fuse box. Turn on the heater and check if it’s working properly.

7. Test the Safety Features

Test the heater’s safety features, such as the overheat protection and tip-over switch, to ensure they are functioning correctly.
