Know Everything About Garage Heater Installation


A carport and garage have long been popular home additions, providing shelter for vehicles and extra storage space. However, in recent years, garages have become the more prominent option. In fact, according to 2019 data, 65% of new homes in the United States have two-car garages.

As such, maintaining and keeping the garage functional has become crucial. Among the popular additions to garages is the installation of a garage heater, which provides comfort during colder months and protects vehicles from damage caused by extreme temperatures.

This article will discuss everything you need to know about garage heater installation, including tips and tricks for a successful installation. By following these steps, you can be sure your garage heater will function optimally and keep your car, garage tools, and other items stored in the garage warm and protected.

What Is A Garage Heater?

A garage heater is a heating system designed specifically for garages or similar spaces. It helps maintain a comfortable temperature in the garage during colder months, protecting vehicles and other items stored in the room.

Different Types Of Garage Heaters And Their Features

There are several types of garage heaters available in the market today, each with its own set of features and benefits. Below are some of the most popular types of garage heaters and their features:

Gas Heaters

Gas heaters are powered by natural gas or propane and are ideal for oversized garages or workshops. They are known for their fast and efficient heating capabilities and can easily maintain a consistent temperature in the space. Gas heaters are relatively low-maintenance and can provide years of reliable service.

Electric Heaters

Electric heaters are powered by electricity and are best for smaller garages or spaces where a gas line is unavailable. They are easy to install and operate and require little to no maintenance. However, they are typically more expensive to run than gas heaters and may not provide the same level of heating capacity.

Propane Heaters

Propane heaters are similar to gas heaters in that they are powered by propane, but they are typically more portable and easier to move around. They are fit for outdoor spaces or smaller garages and workshops. Propane heaters are known for their efficiency and can provide reliable heat for several hours in a single tank.

How Does A Garage Heater Work?

The exact functioning of a garage heater will depend on the type of heater being used. However, the general principle behind all garage heaters is the same: to generate and circulate heat throughout the space.

Gas and propane heaters burn fuel to generate heat, which is then distributed through the space via a fan or other form of circulation. Electric heaters convert electricity into heat through a heating element, which is then distributed through the area via a fan or other means.

Benefits Of Installing A Garage Heater

Installing a garage heater can provide several benefits, including:

Factors To Consider Before Installing A Garage Heater

Before investing in a garage heater, there are several factors you should consider to ensure you get the right one for your garage. By considering these factors, you can increase the efficiency of the heater and lower your energy costs.

Size and Layout of the Garage

The size and layout of the garage will determine the heating capacity required to effectively heat the space. The height of the ceiling, insulation, and other factors should also be considered.

Fuel Type and Availability

Different garage heaters use different fuel sources, such as natural gas, propane, or electricity. The availability of fuel in your area, as well as the cost and efficiency of the fuel, should be considered when choosing a heater.

Heating Capacity and Efficiency

The heating capacity of the heater should be appropriate for the size of the garage. Additionally, the efficiency of the heater should be considered to ensure it is cost-effective and does not consume excessive energy.

Budget and Cost of Installation

The heater and installation cost should be considered, as well as the long-term cost of operating the heater. Choosing a heater that fits your budget and provides good value for money is essential.

Safety Features and Certifications

Choosing a garage heater with safety features, such as automatic shut-off, is important in case of overheating or carbon monoxide detection. Additionally, ensure that the heater is certified by a reputable organization for safety and efficiency.
