How to Heat Your Garage: The Ultimate Guide

Winrow • May 4, 2023

When the temperature drops, it can be a challenge to keep your garage warm and comfortable for those DIY projects or tinkering times. Heating your garage is not only beneficial for your comfort but also for preserving your valuable tools and equipment. In this ultimate guide, we will explore the factors to consider before choosing a heating system, the different options available, the pros and cons of each option, and the best practices for installation.

Determine Heating Needs

Before selecting a heating system, you must calculate the required BTU output for your garage. To do so, measure the volume of your garage, considering the ceiling height, the door size, and the number of windows. Insulation is also crucial for maintaining heat within your garage. Poor insulation may result in high energy costs and difficulty in keeping your garage warm.

Types of Heaters

There are different types of heaters to choose from, depending on your needs, budget, and preferences. Forced-air heaters use natural gas, oil, or propane and distribute warm air through vents or registers. Convection heaters, which may be powered by electricity, natural gas, or propane, heat the air that rises to the ceiling before circulating back down. Ductless heating and cooling split systems meet high energy guidelines, control temperature remotely, and operate noiselessly. In-floor heat that uses PEX tubing helps create a toasty-warm dream garage. Propane heaters, affordable options that come in various sizes. Electric ceiling panels, thin electrical panels that mount on ceilings for efficient energy use. 240v hard mounted electric heaters are also an option.



Pros and Cons of Heating Options

Each heating option has its advantages and disadvantages, according to your preferences. For instance, forced-air heaters are efficient and provide immediate heat but can be noisy and unsuitable for occasional use. In contrast, ductless heating and cooling systems are more expensive but offer consistent temperatures and control with their remote features. Propane heaters are a cost-effective option but require adequate ventilation to prevent health hazards. Electric ceiling panels are easy to install but may not offer enough warmth for larger garages.

How to Install a Garage Heater

The safest and most efficient way to install a garage heater depends on the type of heating system chosen. Forced-air heaters require proper venting, and ductwork installation, while in-floor heating requires burying pipes under layers of concrete. You should also follow safety tips to prevent fires and gas leaks, such as testing the carbon monoxide detector, checking the heater's electrical connections, and avoiding flammable materials nearby. Lastly, common issues during installation may include insufficient or poor wiring, inappropriate sizes, and blocked vents, which can be prevented with proper preparation and planning.


It's recommended to use a qualified expert to install any garage heating equipment.

What are the different types of garage heating?

Insulate the Garage:

Properly insulating a garage is crucial in keeping it comfortable during the winter months. The first step in insulating the garage should be adding plastic shrink films over the windows. This simple and inexpensive solution helps to prevent heat loss and keep the inside temperatures stable. It is also important to insulate the walls, ceiling, and garage doors with insulation materials of adequate R-value. This helps to prevent cold air from entering the space and keeps the warm air inside, making the space easier to heat and more energy-efficient. 


Forced-Air Heater:

When heating a workspace like a garage, a forced-air heater may be the most effective option. These heaters run on either gas or propane and can quickly blast hot air across the room. One potential drawback to this type of unit is that dirt and debris can be blown around due to the forced airflow. To use them most effectively, the heater must be placed near the door to create a circulation of hot air that will move across the entire garage.
