DIY Garage Heater: Stay Warm and Save Money

Importance of a Garage Heater

As the winter season approaches, having a garage heater becomes imperative to ensure a comfortable environment in the garage. Garage heaters not only keep the space warm and cozy but are also beneficial for the longevity of the equipment and vehicles kept in the garage. Here are some reasons why a garage heater is essential:

Protect the Vehicle

Most homeowners keep their cars in the garage to protect them from the harsh elements of the weather. However, if the garage is not properly heated, the vehicle will not receive the full protection it needs. Low temperatures can have a significant impact on a car’s engine performance, tire pressure, and battery life. When you have a garage heater, it helps maintain the temperature in the garage, ensuring your vehicle is safe from the cold, and it can perform as per expectation every morning when you start it.

Longevity of Garage Equipment

The garage is not only a place to park vehicles but also serves as a workshop for many homeowners. They use power tools, compressors, and other equipment in the garage, and these tools can be damaged when exposed to extreme temperature changes. A garage heater will keep the temperature consistent and will reduce the chances of damage, leading to longevity of the equipment and tools.

Comfortable Work Environment

Cold weather makes it challenging to concentrate and work efficiently. A garage heater can make the space comfortable and allow you to work without freezing your hands or toes. Being warm while working in a project is appealing and helps you complete it without any discomfort. When it comes to DIY projects, no one wants to wear heavy jackets, gloves, and boots to stay protected from the cold.

Protect the Items Stored in the Garage

Most homeowners use the garage as storage space. They keep their bikes, boat, and other summer equipment in the garage during the winter season. The cold temperature can cause damage to these items. Using a garage heater will extend the life of your stored items, allowing them to function perfectly when they are used again during the summer season. Furthermore, if you have any chemicals stored in the garage, like paint, that are sensitive to cold temperatures, a heater will ensure that they are not damaged.

Increases Property Value

A garage heater is an investment that not only makes your life comfortable but can also increase the value of your property. When you have a warm garage that can be used to store and work on projects, it adds value to the property. If you are planning to sell your property and have a garage heater installed, it can be an added advantage that can increase the selling price.

Save on Energy Bills

Most homeowners switch on the heat in the living spaces to escape the cold. However, a garage heater will allow you to switch off heating in other areas of the home that are not frequently used, reducing your energy bills. Furthermore, if you choose the right type of garage heater that is fuel-efficient, like a natural gas heater, it will help you save money on energy bills.


In conclusion, the importance of a garage heater cannot be overlooked. It not only keeps you warm and provides a comfortable working environment but also increases the longevity of your equipment and stored items in the garage. It reduces the chances of damage to your tools and also saves on energy bills. Installing a garage heater is a wise decision that will benefit you in different ways and will add value to your property if you ever choose to sell it.

Types of DIY Garage Heaters

When considering a DIY garage heater, there are a variety of options to choose from. Of course, the type of heater you choose will depend on your garage’s size, insulation, and intended use. Let’s discuss a few different options.

Wood-burning stove

A wood-burning stove is a classic choice for a garage heater. Not only can it produce a lot of heat, but the stove itself has a rustic look that pairs well with many garages. To install a wood-burning stove, you’ll need a chimney installed, which can either be inserted through the roof or through the side of the garage. Keep in mind that this option requires a steady supply of wood to keep the fire burning, and it may not be the most efficient way to heat your garage.

Infrared heater

Infrared heaters use electromagnetic radiation to produce heat, which means they don’t rely on air to distribute warmth. This makes them an efficient choice for a garage that lacks insulation, as they don’t waste energy by heating up the air around them. Infrared heaters come in a variety of sizes and styles, so it’s easy to find one that works for your space. They’re also relatively easy to install, and many models come with mounting brackets to make the process even simpler.

Kerosene heater

Kerosene heaters emit a lot of heat and are a popular choice for garages and workshops. They’re compact and easy to move around, so you can direct the heat where you need it. Most models have a tank that needs to be filled with kerosene, so you’ll need to make sure you have a steady supply. Keep in mind that kerosene heaters can produce fumes, so make sure your garage is well-ventilated before using one.

Propane heater

Propane heaters are a convenient option for garages that lack electricity. They use propane gas to produce heat and come in a variety of styles, from small portable models to larger stationary units. Most models have a built-in thermostat, so you can control the temperature of your garage easily. However, propane heaters can produce carbon monoxide, so it’s important to make sure your garage is well ventilated before using one.

Electric heater

If you have access to electricity in your garage, an electric heater can be an efficient and easy-to-use option. Electric heaters come in a variety of styles, from small portable units to larger wall-mounted models. They’re relatively simple to install, and most models have a built-in thermostat to help you regulate the temperature of your space. However, keep in mind that electric heaters can be expensive to run if you’re using them for extended periods of time.

As you can see, there are a variety of DIY garage heaters to choose from. Consider your garage’s size and insulation, as well as the level of heat you need, before choosing a type.

Materials and Tools Needed for Building a Garage Heater

Building a DIY garage heater is an excellent way to stay warm while working in your garage. It saves you from the cost of purchasing a new one and can be a fun and exciting project to do. However, it is important to know the materials and tools required for constructing a garage heater before starting the project. Here are the materials and tools needed for building a garage heater.

Materials Needed

The materials required to build a garage heater are pretty easy to acquire and can be found at any home improvement store. They include:

1. A steel drum or a similar container:

You can either buy a new steel drum or use an old one if you have it. It is essential to have a proper container that can hold wood, a crucial source of fuel for the heater.

2. A stovepipe:

A stovepipe will serve as the conduit through which the heated air is channeled from the heater to the garage. It would help if you got a stovepipe that fits your heating drum for efficient heating.

3. A chimney cap:

It will prevent rain or snow from getting into the heating drum. Make sure the cap is the right size for your stovepipe.

The tools necessary to build a garage heater are minimal. They may be in your workshop already. You will need:

1. Cut-off saw:

You would require a cut-off saw to cut the steel drum and the stovepipe to the required lengths.

2. Welder:

You need a welder to attach the stovepipe flange to the top of your steel drum, to attach legs to the base of the drum, and to weld the door into the drum.

3. Angle grinder:

An angle grinder is useful for smoothing metal surfaces, such as the edges of the cut steel drum, and for cutting the stovepipe to the desired size.

4. Fire-resistant adhesive:

This serves as the glue that holds the firebrick in place; it is necessary to use heat-resistant adhesive to ensure the firebrick does not fall off when the heater is in use.

5. A welding helmet:

It is important to have a welding helmet to protect your eyes and skin from arc flashes that can cause welding burns and damage your eyesight.

In conclusion, building a DIY garage heater is an excellent way to stay warm and comfortable while working in your garage. It is essential to know the materials and tools required to build your garage heater before starting the project. With proper guidance and the right tools and materials, anyone can build a garage heater and save money while doing it.

Step-by-Step Guide on Building a DIY Garage Heater

That’s why many people choose to build their own DIY garage heater instead. Here’s a step-by-step guide to building your own heater:

1. Determine the size and location of your heater

The first step is to decide on the size and location of your DIY garage heater. Measure the dimensions of your garage and determine the most appropriate location for your heater. Take into consideration factors such as ventilation and access to electrical outlets.

Safety Tips when Using DIY Garage Heaters

DIY garage heaters can be a great option for those who are looking to save some money on heating costs in the winter months. However, before you start using a DIY garage heater, there are some important safety tips that you need to keep in mind to prevent any potential accidents. Here are 5 safety tips that you should consider before using a DIY garage heater:

Tip #1: Choose the Right Type of Heater for Your Garage

Not all types of heaters are suitable for use in a garage. In fact, some types of heaters can be dangerous and even cause a fire if they are not used properly. Before purchasing a DIY garage heater, you need to consider the size of your garage, the type of fuel that you want to use, and the specific needs of your garage for heating. Some popular options include propane heaters, electric heaters, and kerosene heaters.
