8 Fantastic Heaters for Your Shed [Review]

If you have a shed in your backyard, you probably use it for all kinds of things. 

A shed can be great as a storage unit, but you can also use it as a workshop, workout area, or extra room. The only downside is that it can get cold in the winter.

Fortunately, many different heaters for a shed can make it more comfortable. 

Depending on the size of the shed and how cold it gets in your area, you can find a heater that will suit your needs best. To help get you started on your search, I have compiled a list of 8 fantastic heaters for a shed.

You can make good use of your shed by knowing what the best heaters on the market are and what they have to offer. 

What to Look for in Heaters for a Shed 

When searching for heaters for a shed, you need to know what you should be looking for. 

Perhaps most importantly, a heater should have enough power to heat the entire building. This means matching the wattage to the size of the shed. A common rule of thumb is about 10 watts per square foot. 

The power output of a heater is measured in wattage. An uninsulated shed needs more than the 10 watts per square foot that suits a typical room, so allow extra. 

You should also look for safety features. 

The heaters for a shed you look at should have things like overheating protection, roll-over shut-off, and timers. These lower the risk but do not remove it. Plug the heater straight into a wall outlet, keep it at least three feet from anything that can burn, such as sawdust, wood and paint, and turn it off when you leave. 

8 of the Best Heaters for a Shed

There are many different heaters for a shed on the market and they all have different features and strengths. I have assembled a collection of 8 of the best heaters for a shed with different designs and accessories so you can find the right one for your needs. 

Best Overall: Dr. Infrared Heater

• Power Source: Electricity 
• Wattage: 800-1,500

The Dr. Infrared heater is a wall-mounted unit that uses infrared heat to heat places like garages and sheds. It is approved for both indoor and outdoor use, making it a great choice for an outbuilding. 

With a versatile wall-mounting bracket, you can hang this heater wherever you need it most. 

It uses a reflective high-level mirror to give an even distribution of heat. The mirror helps send more heat toward you, but it costs the same per watt to run as any electric heater. 

It has three different power modes: 800, 1,200, and 1,500 watts. 

With the ability to change the heating output, you can use this heater all year long and stay warm no matter what. 

Fastest Heating: Buyplus Outdoor Heater

• Power Source: Electricity 
• Wattage: 1,500

When it comes to keeping your shed warm, the last thing you want is to wait for your heater to come up to temperature. 

The Buyplus listing claims a heating time of three seconds. That is quick, but an infrared heater warms you and objects rather than the air, so a cold shed will take time to feel warm. 

It is approved for both indoor and outdoor use and is incredibly portable. With a small footprint and lightweight design, you can easily move it from the house to the shed if you want to use it in different areas. 

It also includes overheat protection, which lowers the risk, though dust and flammable fumes in a workshop are a separate hazard, so keep the heater clear of them. 

Lowest-Profile: VAGKRI Outdoor Heater

• Power Source: Electricity 
• Wattage: 620-1,500

One of the downsides of using heaters for a shed is the fact that they can take up so much room. 

This VAGKRI outdoor heater features an ultra-low-profile design for tight spaces. It can sit right in the corner and be out of the way while you work on your hobbies or work out. 

It is approved for both indoor and outdoor use. This makes it a good fit for a shed because the listing says it is weather-resistant.

There are nine different power settings ranging from 620 watts to 1,500 watts. 

It also features a timer that you can set for anywhere between one and 24 hours to make it as efficient as possible.

Most Portable: ISILER Space Heater

• Power Source: Electricity 
• Wattage: 1,500

If you are always moving between your shed and your home, you probably want a heater that can easily move with you. 

This ISILER space heater has an incredibly portable design. Its dimensions are

6.7 inches x 6.4 inches x 6.2 inches, and it weighs just 42.3 ounces. 

Despite its small stature, it has a 1,500-watt power output. The listing says that covers a 108-square-foot room. Measure your shed, because an uninsulated shed needs more power than the same size room indoors. 

It also has an adjustable thermostat to lower the heat once the shed is up to temperature and save money on your power bill.

Most Powerful: KEN BROWN Electric Garage Heater

• Power Source: Electricity 
• Wattage: 3,000-5,000

If you are looking for a more permanent solution in heaters for a shed, a ceiling-mounted unit could be the answer. 

This electric garage heater by KEN BROWN puts out up to 5,000 watts of power. This makes it a good choice for people who live in cold climates with long winters. 

It has a housing made of heavy-gauge steel, so it is built to last for many years. It is also hard-wired to a 240-volt circuit, like the one an electric dryer uses, so have a licensed electrician install it. 

With a convenient dual-knob design, you can easily reach the heat output and the power switch. 

Best Directed Heat: Dura Heat EUH4000R Electric Forced Air Heater

• Power Source: Electricity 
• Wattage: 3,750

Forced air is an excellent way to heat spaces quickly. This Dura Heat forced air heater is designed to direct the heat with precision. At 3,750 watts it draws more than a standard 120-volt circuit can supply, so it needs a 240-volt circuit: confirm the voltage on the label and have an electrician install it. 

If you need heaters for a shed that is bigger than usual, this will be a good choice. At about 10 watts per square foot, its 3,750 watts suits roughly 375 square feet.

This heater can either be used on the ground or mounted to the ceiling with the included mounting bracket. 

It includes a remote for making power adjustments, which is convenient if you mount it on your ceiling. It also has a stainless steel construction, so it is highly durable for applications outside the shed, like construction sites or larger garages. 

Most High-Tech: Dreo Smart Wall Heater

• Power Source: Electricity
• Wattage: 1,500

When choosing heaters for a shed, it is important to consider convenience. While it might be enough to have an on/off switch and nothing else, having all the adjustments and settings in your pocket is helpful.

The Dreo wall heater has Wi-Fi, so you can switch it on from the house before you walk out, or ask Alexa to warm the shed.

It also carries an IP24 splash rating, which suits a damp outbuilding better than a plug-in heater on the floor, and it mounts on the wall with the included template. Dreo rates it for 150 square feet as a main heat source. It replaces the Govee heater we listed before, which was recalled in November 2024 (CPSC).

Simplest: TEMPWARE Milkhouse Space Heater

• Power Source: Electricity 
• Wattage: 1,300-1,500

Sometimes, when it comes to heaters for a shed, simpler is better. 

The TEMPWARE milkhouse space heater is designed for all kinds of heavy-duty applications. This makes it perfectly suited for a shed workshop or workout space. 

It runs a fan, so it is not silent, but it is a simple heater with two settings (1,300 and 1,500 watts, per the listing). 

The listing says this heater is ETL listed, which means it was tested to US safety standards. That does not make it safer than other listed heaters. 

It also comes with three different power levels: fan-only, 1,300 watts, or 1,500 watts.
