Heating For Garage Gym (Best Solutions For Small Spaces)

Garage gyms are more popular than ever, and we've seen over the last couple of years just how innovative people can be to fit a high-quality gym in their garage. However, no matter how good your garage gym setup, if you don't have the right temperature in your garage gym, it can seriously impact your performance.  

As we approach the coldest months of the year, you need to start thinking about heating your garage gym. In this guide, we'll help explain the best heating for garage gym to keep you warm during winter workouts. 

You might be thinking, why is temperature important? I'm just going to get warmer while I work out anyway. You're right, but if you have the wrong temperature in your garage gym is can seriously impact your health.  

If the garage is too warm, it can lead to dehydration and fatigue; if it's too cold, it can cause your muscles and joints to tighten, which can lead to injury. It can also be harder to motivate yourself to work out if you have to go into an ice-cold room.  

A properly heated garage gym will help to protect you and your equipment. It will make it easier to work out for longer and help to maximize your gains over the winter months.  

What To Look For When Choosing Heaters For Your Garage Gym

There are a lot of heaters available that can be used in garage gyms, and it can be challenging to know which is best. To help get you started, we've given a list of the key factors to consider so you can hopefully narrow down your search: 

High & Low Heat Range 

The heat output from a heater is measured in British Thermal Units (BTUs). The more BTUs your heater gives out, the more heat you'll get from the device. Generally, the bigger the room, the more BTUs you'll need, so you'll need to find a heater that is large enough to heat the room.

Remember, the more BTUs, the more energy you'll use, so don't get a heater that's too big, or your energy bill can spike. Instead, try to find a garage gym heater that will heat the space effectively. 

Safety Features 

Most house fires in America are caused by space heaters, and it's crucial that you buy a safe heater. Look for a garage heater that is fully certified, so there's less risk of a malfunction. Most modern heaters also have integrated safety features that switch the device off if it overheats or topples over. It's worth looking out for these features so you can guarantee your safety and the safety of your family.  

Easy & Secure Mounting Options 

In a small garage, you're going to have limited floor space. A heater can take up that valuable space and leave you less room for equipment or to work out. It's worth looking at the different mounting options available to see if they can be installed on your wall or ceiling. Always look for easy mount options, so you don't need to pay a professional for help.  

Adjustable Louvers 

Louvers are used to direct heat from the device into your room. A garage gym heater with adjustable louvers will allow you to focus the heat where it’s needed most and help you get the benefit of the device.  

Efficient Running Costs 

Garage heaters, particularly space heaters, can be very costly to run. Energy bills are at an all-time high globally, so it pays to look for an energy efficient model. Gas is typically cheaper to run than electric, so it’s worth exploring these options.  

Favorable Warranty 

Garage heaters are a particularly useful piece of equipment and should be treated as an investment. Look for a good warranty to help protect your purchase and increase the longevity of the heater. Typically, garage heaters will offer a 1–2-year warranty, but some brands will offer 5 years or more. It’s worth exploring the market to find a good warranty.

Heating Options For Garage Gyms (Best Solutions For Small & Large Spaces) 

There are a lot of different heaters which can be used in a garage gym. Each have their pros and cons, but it pays to understand the options so you can choose the best one for you. Here's a quick breakdown: 

Electric Space Heaters 

Electric space heaters work by drawing in cold air, heating it within the mechanism, and then blowing it quickly into the room. This then heats the area and should raise the temperature of the room. They’re usually really quick and easy to set up, and you can just plug them in and go.  

While space heaters are cheap and simple, they aren't always effective in cold garages. The smaller models will struggle to raise the temperature of an uninsulated room, and you might not feel the benefit. They can also be expensive to run. 

If you have a small garage and live in a moderate climate, then any home electric space heater can work. You'll probably need to invest in some insulation to really feel the benefits, and always make sure you remove all flammables as electric space heaters can pose a fire hazard.  

Natural Gas & Liquid Propane Heaters 

Natural gas and propane are regarded as some of the most efficient fuels which produce a lot of heat. They work by using the gas to power a heating mechanism that warms the air and circulates it in your home. They’re well suited for larger spaces or very cold conditions, though you’ll need to get a model with the right amount of BTU.  

Natural gas and propane heaters are an effective way to heat your garage gym and will work in a small or medium space. They won't take up much room and are cheap to run, but they are a bit more complicated to set up. This is a really effective type of heater if you have cold winters and want your gym to stay warm throughout.  

Forced Air Heaters 

Forced air heaters offer a lot of heat very quickly. They usually need an electrical power source and some kind of gas to fuel them, so they aren't cheap to run, but they are effective. There are portable or fixed models, but they are a bit more expensive than other types of garage heater. That being said, they also offer a lot more BTUs so you can warm a larger area.  

If you do choose to go with a forced air heater, then you'll need to make sure it's properly ventilated. You'll usually need a professional to help you with this, and it adds to the cost. If you can afford a forced-air heater, then they will keep you warm, and they work well in medium or large garages. Try to find a wall mounted unit so that you don't take up too much floor space with one of these.  

Infrared Radiant Heaters 

Infrared heaters work differently from traditional heaters as they provide direct heat through light rather than heating the air around you. You'll tend to feel the heat more with infrared radiant heaters because they heat you directly, and you can focus them on areas that need to be heated more quickly.  

Infrared radiant heaters are best suited for small or medium garages because the larger infrared heaters are too dangerous to use indoors. They carry a higher upfront cost than other heaters but are pretty cheap to run, so you may realize some long-term savings. 

They provide some effective heat but can be uncomfortable if they're pointed directly at you while you exercise. The best thing to do is turn it on slightly before you workout and leave it off while you exercise. 

Convection & Wall Heaters 

Convection heaters are essentially modern furnaces that provide a lot of heat to the room. They're quite big and clunky and carry a reasonably high upfront cost. They won’t work well in small garage gyms because there isn’t enough space, but they will warm a large garage quickly.  

This type of convection heater can be dangerous to leave unattended and will need proper ventilation. You shouldn't need to leave it running all the time, though, as it will heat the space quickly, so just make sure you don't leave it unattended.

If you have a large garage, then you need a more powerful heater to warm the space. The Mr. Heater model does exactly that by producing a lot of heat fast to power through cold conditions.

This heater is perfect for those with a large, drafty garage who live in cold conditions, but it's probably overkill for a smaller garage. It is safe, but you need to make sure you keep flammable materials at least 3 feet from the heater, so we recommend wall mounting it to keep it out of the way. It is more expensive than many other heaters but worth the investment if you need the power.

Other Ways To Beat The Cold In Your Garage Gym 

Heaters are the best way to warm your garage gym, but there are some other methods you can use to stay warm in the colder months: 

Insulate The Garage 

Insulation won't warm the garage directly, but it will help keep the heat in your home. When used in conjunction with a heater, you can really feel the benefit and raise the temperature of the garage gym quickly.

You should focus on sealing your windows with insulating foil and fitting draft excluders to the doors, as this is where the cold air gets in. Use a sealant to fill any holes in the walls, floors, and ceilings and look at getting insulation professionally installed to help maximize warmth retention.

Use Rubber Flooring 

Rubber gym flooring helps put an extra layer between you and the cold ground under your garage. This helps to keep the heat in and cold out, but also has the added benefit of giving you an even, quiet surface for lifting weights on. Rubber flooring is inexpensive, and you can usually fit it yourself. Make sure you get the right thickness of rubber gym flooring to protect the floors and keep the warm air in.

Layer With Warm Clothes 

Wearing warm clothing might seem obvious, but it’s the simplest way to stay warm. It can be tempting to strip down to work out, but if your garage gym is cold, you’ll need to layer up. Look for breathable layers which keep the heat in but still allow your body to sweat.  

Hang Tarps Around the Garage Gym 

Tarps help to insulate your garage and can be particularly effective on doors and windows. By hanging them on your walls, you help keep the heat in and prevent heat loss from your home.  

Warm Up Your Barbell & Dumbbells 

Your weights can become very cold, especially if they are metal. When you go to use the weights, it can impact your body and make you feel colder. It can even make it difficult to grip the bar properly, which in turn can make it hazardous to lift weights. Try wrapping up the weights to keep them warm or storing them inside, so you don't feel the cold on your hands. You can also buy a good pair of weightlifting gloves.

Use Chalk When Lifting 

Chalk helps to improve your grip on the bar and protect your hands from heavy lifting. In cold conditions, it also helps to keep your hands warm, so if the bar is cold, it can help keep you slightly warmer.

What Temperature Should You Keep Your Garage Gym At?

Ideally, you want your gym to be between 68- and 72-degrees Fahrenheit. This allows you to work out comfortably and hopefully achieve the best results. If it’s too cold, your joints can tighten, and when you start to exercise, you can injure yourself.

If it's too hot, you can suffer from dehydration and even pass out. Keeping your gym at an ambient temperature will help protect you and your gym equipment.  

People Also Ask (FAQs)

How can you heat a detached garage gym? 

Garage heaters will work just as well in a detached garage gym, but you need to make sure there’s an electrical outlet that can be used. If not, you may be limited to propane or natural gas heaters.  

Can treadmills be kept in cold weather? 

Treadmills can become damaged if kept in cold conditions for a prolonged period. Ideally, you should move it into a warm area or look to cover it with an insulated material. By warming your home gym, you'll help to protect all your equipment.  

Why is it so hard to exercise in the winter season? 

The cold weather can discourage people from working out, which is why it's so important to have a comfortable space for your gym. It can also be challenging to find the motivation, and naturally, we eat more during the winter months. Many people are tempted to wait until the new year to really start exercising, but consistency is key, so you should keep going during the winter season.  

Is it better to work out in a hot or cold home gym? 

You should try to keep your gym around 70 degrees Fahrenheit as gyms that are too hot or too cold can be hazardous to your health. A cold gym can make your muscles tight and impact them, and a warm gym can make you dehydrated and faint. Try to avoid working out in extreme conditions wherever possible.  


Your garage gym can be fitted with the best equipment, but if you don't have the right temperature, then it can still be an unpleasant experience. Garage heaters are the best way to heat your gym and help you get the most from your workout. Hopefully this guide has helped explain the benefits of garage gym heaters and introduced you to some of the top heaters on the market.
