Best Garage Gym Heaters

One thing that all home gyms, garage gyms, and basement gyms have in common is trouble with climate control. Either they stay too hot, or they become too cold. Heating for garage gyms, in particular, is difficult.

If you have a home gym and need to keep it warm for year-round use, then you have come to the right place. In this article, we will cover why it is important to keep your gym space at the right temperature, how to find the right heater for your needs, and the various options you have to choose from.

Read on to find the best garage gym heaters and solutions to your home gym heating issues.

Different Types of Heaters for Your Garage Gym

As you can imagine, there is more than one type of heater option out there. In fact, for home use, there are at least 6 different types you can pick. So which one is best for you? Let’s take a closer look at the various types of heaters.

Infrared Heaters

One of the most popular heaters are infrared. This is a similar heat to that of the sun. Infrared heaters heat objects and people and less so the air. By emitting light waves that we can’t see, these heaters are quick to warm up the space.

Because the light waves are absorbed by the objects in the room (including you), the objects heat up faster than the air. This technology has been around a while and is a higher initial cost in most cases. However, they are also among the most efficient in terms of energy turned to heat.

Electric Space Heaters

Electric space heaters use electricity to pass through coils, wiring, or electrodes. Similar to an incandescent bulb, the electricity passing through the filament heats up, and the air around the element absorbs the heat.

As the hot air rises, the colder air is pushed down, heated, and rises, creating a small form of air circulation. Electric space heaters are fairly inexpensive, making them quite popular. However, they aren’t as efficient as other types, and a lot of energy is lost without being transformed into heat.

Forced Air Heaters

Forced air heaters use a small electrical current and a fan. Instead of relying on air circulating from rising temperatures, the fans push the air over the heated elements and out into the room. They heat faster than electric space heaters but can be less efficient since they also use energy to run the fan motors.

Forced air systems are also a more permanent mount where other options can be portable. If your home already uses forced air heating, you can add a channel to the system for your garage without it costing a lot.

Portable Radiant Heaters

Radiant heaters, as the name implies, use different methods, including radiant and convection heating, to heat a space. The air is heated in and around the unit, which then radiates out into the room, slowly raising the air temperature and adding warmth to the space.

Because the systems are portable, they tend to be used in smaller areas and near the user. They do require a lot of electrical energy, making them less efficient, but they can heat quickly and may not need to be used constantly to maintain the set temperature.

Natural Gas & Propane Heaters

Gas heaters come in many types, sizes and capacities, but they all work in a similar fashion. Instead of relying solely on electrical power, gas powered heaters burn fuel to produce heat, much like an actual fireplace.

The heat from the flames, burning gas, or chambered burns is passed into the room where it warms the air around the heater. This hot air circulates to bring the colder air towards the heater and the hotter air out into the room.

Propane Convection Heaters

Unlike infrared heaters, convection heat is used to warm the air and not the objects in the room. For example, with a propane convection heater, you don’t use electricity, and instead, the propane is burned in the gas chamber. That heat is then passed on to the air around the unit, heating the garage in turn.

Of course there are safety concerns, and all heaters need to have safety sensors and shut-offs included. With propane, you also have the added cost of refilling propane tanks or buying cylinders to use with the heater.

8 Best Garage Gym Heaters

In this section, we will rate, review and compare the 8 best garage gym heaters. Each one has its own pros and cons, so go through the list and find out which style suits your needs the best.

1. Mr. Heater F232000

Best for Small Gyms
Overall Dimensions 14.3 x 14.3 x 8.9 inches
Weight 9 lbs
BTU Rating 4000, 9000 BTU
Coverage Area 225 Sq. Ft
Run Time 2 to 6 hours
Warranty 1-year warranty

Small space heating is ideal for smaller gyms or garage gyms where you don’t have a large spread of equipment. You can set up this Mr. Heater model, turn it on and get to work. The propane tanks will run between 2 and 6 hours on average, depending on the settings.

There are two settings on this model, low and high. Each will offer either 4000 or 9000 BTU output and can quickly heat a space up to 225 square feet. The rugged build will also handle being knocked, kicked, or even pushed over without complaint, and all the required safety features are included.

The tip-over sensor will shut off the gas supply and the heater in the event you do knock it over while it is running, and the onboard O2 sensor will also shut the system off if oxygen levels fall too low.

This highly portable unit can go anywhere and even has a hose connection, so you can choose to connect to a larger propane tank or use camping style cylinders. The ceramic tile heats up and glows, radiating the heat to nearby objects and persons, giving you warmth any time you need it.

What We Like
  • Ideal for smaller spaces or drafty areas
  • Indoor and outdoor use
  • Excellent customer service
  • Tip over and low oxygen sensors
  • Extra durable shell
What We Don’t Like
  • Can run out of propane before workout is complete
  • Hose and fuel filter accessories additional charge

2. NewAir

Best Ceiling Mount Electric Model
Overall Dimensions 8.9 x 9.1 x 11.25 inches
Weight 15 lbs
BTU Rating 17000 BTUs
Coverage Area 500 Sq. Ft
Run Time N/A
Warranty 1-year warranty

If you are looking for a more permanent solution, the hardwired electrical NewAir heater might be for you. Unlike many other models, this unit doesn’t plug in, so you don’t need a new circuit. Instead, it is hardwired to an existing circuit that takes only a few minutes to install.

You can mount it on a wall, ceiling, or in a corner and adjust the angle and pitch to meet your needs. Once installed, you can set the thermostat dial on the rear of the machine and let it work.

Many owners find that wiring it to a light switch works great to turn it on and off when needed, and the adjustable thermostat can be set during install and left alone after that. If you hardwired it without a switch, the unit will run when the power is on and the temperature is below the thermostat setting. Once temp is reached, it will shut off on its own.

The rugged frame and adjustable louvers are made for harsh conditions and make this an ideal garage heater with low maintenance. Once a season, you do need to access the system and clean the louvers and fans to prevent dust from igniting, but the initial burn-off when first used in the winter won’t be cause for alarm, though there may be a burnt odor or light smoke.

The 1-year warranty is inclusive and will cover everything except the installation. Should you need to use the warranty to make a claim, NewAir will be helpful after initial contact is made.

What We Like
  • Easily installs into any 30-amp circuit
  • wall and ceiling mount capable
  • Fully adjustable louvers
  • Auto shut-off and overheat sensors included
  • Thermostat controlled
What We Don’t Like
  • 1-year warranty could be longer
  • Not the most stylish heater on the market

3. Heat Storm HS-1500-PHX-WIFI

Best Wall Mount Infrared Heater
Overall Dimensions 4 x 19 x 16 inches
Weight 9 lbs
BTU Rating Approx 1500 BTUs
Coverage Area 150 Sq. Ft
Run Time N/A
Warranty 1-year warranty

The Heat Storm wall mounted infrared heater isn’t going to blast you with heat. Instead, it will steadily raise the temperature of the space to a comfortable setting over time. As with any infrared heater, it offers quiet operation and a gradual increase in temperature.

If you are looking for a heater that will blow hot air directly on you, this is not it. However, if you want a wall heater that is controlled by a smart device and allows you full customization, you found your heater.

With a full digital display, you can install and set up this heater in your garage in about 15 minutes and pair it with a Smart Life link, which works with Google Home or as a stand-alone. You can set the child locks, temperature mode, and heat range right from your phone or tablet.

If you are looking to save a little money, they also have a gray or white model that is not WiFi enabled for a lower cost.

Either way you go, though, the radiant infrared heat will get your garage up to temp so you can work out in comfort. It is capable of heating spaces up to 150 square feet, and with a lifetime, washable air filter, you won’t have any further expenses after the initial purchase.

This unit plugs into any standard 110-volt outlet and has tip over and overheat shut-off protection included. The grill is safe to the touch and doesn’t produce any fumes, so if your garage is not well ventilated, you don’t have to worry.

Along with the 1-year warranty, the WiFi model also features power outage setting recall, so your settings will return when power is restored. Now your winter or early morning workouts can be done in heated comfort.

What We Like
  • Simple installation and mounting
  • WiFi-enabled for smartphone control
  • Lifetime washable filter included
  • Ultra-quiet operation
  • Safe-touch grill
What We Don’t Like
  • Can take a while to warm the space
  • Customer service may be slow to respond

4. Multifun

Super Small for Instant Heat
Overall Dimensions 6 x 6.5 x 7 inches
Weight 2.45 lbs
BTU Rating Approx 1500 BTUs
Coverage Area 150 Sq. Ft
Run Time N/A
Warranty 1-year warranty (90-day refund)

If you are an early riser and need heat in your gym quickly, this little heater may be just what you need. The Multifun portable heater offers rapid heat technology that can have you ready in less than 10 seconds.

The fireproof metal housing is sturdy and raised to offer a great angle for heating regardless of whether you place it on the floor or a tabletop. The turn dial thermostat allows you to control how much heat is produced, and the internal fan will push out warm air faster than you think.

It features an auto shut off and overheat protection from burnout, tip-overs, and knocking. It is also rugged and sturdy, so you don’t have to worry about it breaking on you.

This compact heater doesn’t take up much space, but don’t let that fool you. For near-instant heat, this ceramic plate heater will produce a lot of hot air quickly. While it is marketed as rapid heat in 2 seconds, it will actually be closer to 10 to 15 seconds before the space is comfortable.

It is also important to note that this is not a magical heater that will somehow heat your entire home. With 1500 watts, it is capable of heating up to about 150 square feet, if your garage is well insulated.

However, it is a forced air heater, too, with the fan pushing the hot air around the room, so placing it near you will give you all the warmth you need while working out.

What We Like
  • Heats quickly
  • Auto tip-over shut off included
  • Compact design won’t get in the way
  • All metal flame retardant construction
  • Quiet operation
What We Don’t Like
  • Becomes hot to the touch
  • Warranty claim can be difficult

5. Mr. Heater MH60QFAV

Best Propane Model for Large Spaces
Overall Dimensions 15.98 x 8.82 x 13.5 inches
Weight 13 lbs
BTU Rating 30000 to 60000 BTUs
Coverage Area 1500 Sq. Ft
Run Time Up to 14 hours
Warranty 1-year warranty

Mr. Heater makes another appearance on our list with the best propane model for large spaces. This propane fueled forced air heater is designed for garages, large spaces, and even exterior use.

There are several sized models to choose from, but the 30-60000 BTU model is on display here. It features a turn-dial selector for either 30,000 or 60,000 BTU output and a push-button ignition.

Once lit, the unit will continuously ignite to keep the flames active. The burners produce clear blue flames that make a lot of heat which is then fed through the ejection tube by high forced fan-created airflow.

Commonly called torpedo heaters, this unit can heat an entire garage in minutes and keep your place warm for your entire workout. It uses a hose connection to a 20-pound propane tank that will run for about 14 hours or more, depending on the temperature settings.

Like all Mr. Heater models, this features the excellent customer service from Mr. Heater and a full 1-year warranty. The 2-piece construction takes only minutes to assemble and comes with an ergonomic handle for easy transportation.

What We Like
  • Quiet Burner Technology for 50% noise reduction
  • Ergonomic transport handle
  • Rated for external use or large space operation
  • Variable-rate propane fed burner
  • Continuous ignition system
What We Don’t Like
  • 1-year warranty only
  • Not suitable for closed garages or small spaces

6. DIMPLEX DGWH4031G

Cheapest Hanging Model
Overall Dimensions 11 x 7.25 x 9 inches
Weight 12 lbs
BTU Rating Approx 4000 BTU
Coverage Area 250 Sq. Ft
Run Time N/A
Warranty 1-year warranty

If you want continuous heating in a compact model that heats as quickly as it is rugged, look no further. The Dimplex wall hanging electric forced air heater is that model. Unlike the NewAir model, this one has a wall mounting bracket that it will hang from. It also doesn’t feature adjustable louvers, so the heat comes out the front to heat the entire space instead of directing the heat to a single area.

The high-speed fan is quiet when running but moves a lot of air to heat your garage quickly. It also features a stainless steel heating element for years of continuous use without fail.

It isn’t a hardwired unit and comes with a 240 volt NEMA plug that requires a dedicated 20 – 30 amp circuit. The downside is that the cord is only 6 feet long, so hanging high on the wall or in a specific area of your garage may require installing a new circuit and outlet.

The Dimplex heater is rugged and durable. Constructed of high-grade steel and powder coated with epoxy prevents corrosion and damage. It can also pivot and swivel on the bracket to point in a director for some heat area control.

The  1-year warranty is easy to claim if it ever comes to that. But we find that once installed and operational, you won’t have any issues with this model for years to come.

What We Like
  • Heavy-duty construction
  • Stainless steel heating element
  • 4000 watts of power
  • Thermostatic control and fan delay included
What We Don’t Like
  • 1-year warranty is a little low
  • No adjustable louvers

7. Dr. Heater DR-910F

Top of the Range
Overall Dimensions 22 x 18 x 16 inches
Weight 49 lbs
BTU Rating Approx. 8000 BTU
Coverage Area 450 Sq. Ft
Run Time N/A
Warranty 1-year warranty

The Dr. Heater (not to be confused with Mr. Heater) infrared ceiling mount heater is a forced air infrared permanent mount heater designed for garages and workspaces. This model is hardwired only and will run on any 240 volt circuit.

The remote controlled heater has all the safety features you can ask for, including auto shut off, thermostatic control, and overheating protection.

It may require professional installation if you don’t have an active power circuit near the mounting area. However, once wired, it can be mounted and positioned in a few minutes.

It will rotate and pivot to where you need it most and has five individual adjustable louvers to direct the heated air in all directions. With a set temperature range between 50 and 90 degrees Fahrenheit, you will get all the heat and comfort you need from this top of the range model.

Rugged steel construction, flame retardant materials, and timer modes of operation ensure you get the most out of the heater with the least amount of effort. And, because the motor is heavy-duty, pre-lubricated, and completely sealed, it is virtually maintenance free.

What We Like
  • Low Maintenance
  • Heavy-duty steel construction
  • Remote control operation
  • Timer feature included
What We Don’t Like
  • 1-year warranty lacking
  • Heats slowly compared to other models

8. NewAir NGH160GA00

Best Portable 120v Model
Overall Dimensions 8.6 x 8.6 x 10.3 inches
Weight 6 lbs
BTU Rating Approx 1750 BTUs
Coverage Area 160 Sq. Ft
Run Time N/A
Warranty 1-year warranty

NewAir is back again, too. This time with a personal heater designed to go wherever you go. The solid construction and near-instant heat mean you can work out any hour of the day at the ideal temperature.

This small but mighty heater features turn dial temperature selection and fan speed. It also pivots on its stand so you can direct air where you need it. The small heater can be used on the floor, workspace, or bench and won’t get in the way.

Should something happen to it during your workout, though, you don’t need to worry. With auto shut-off and overheating protection, it is as safe as they come.

With 120 volts of power pushing the 200 CFM fan and a ceramic heating plate, you get near-instant heat that is easily controlled. However, due to the small stature of the heater, it is designed and best used for personal or spot heating.

Don’t expect this model to heat your entire garage, but wherever you are, this heater will keep you warm.

What We Like
  • Compact design
  • Easily portable tabletop set
  • Turn dial settings
  • Internal thermostat and safety shut off features
  • Rugged design
What We Don’t Like

Importance of Correctly Heating Your Garage Gym

Maintaining the proper temperature in your home gym is critical to your performance, health, and safety, as well as that of your equipment. Just as you need to warm your muscles before working out, you also need to be warm yourself.

If the air and garage are too cold, your muscles will contract, shiver, and burn energy, keeping your body warm. When this happens, you can actually negate your workouts because the muscles aren’t able to work as hard to lift when the energy stores are being used to keep you warm.

Proper temperature in the gym space can keep your muscles ready for the workout and allow the heater to warm your body. Heaters can also help lower humidity levels, evaporate moisture, sweat and other contaminants and help keep your gym equipment from rusting, corroding, or growing mold or bacteria over time.

How To Choose Heaters For Garage Gym: Buying Guide

Before you head out and purchase any garage gym heater, there are several factors you need to consider. Here we explain those factors and why they are important to your final buying decision.

Mounting Vs. Portable

One of the first major decisions you need to make is to decide if you want a permanently mounted heater or a portable one. Each has its own sets of pros and cons, but one may work better for your particular setup. Larger spaces generally work better with portable units, for example.

High Heat Capacity

Higher heat output can mean the difference between an ideal gym temperature and not using the space until spring. However, the higher the output potential, the more risk for overheating. You need to ensure that the BTU output of the heater is in the recommended range for the size of your home gym.

Too small of a heater will cost more to run without properly heating the space. If it is too large, you will spend more on your energy bills and can potentially cause you to get too hot.

Safety

Safety when working out is always important, and that extends to your workout temperature. Heaters are a risk for fire, igniting flammable objects or liquids, and with garage and basement gyms, ventilation is also essential. Make sure your heater has the proper safety features, cut-offs, sensors, and shut-down options they need to remain safe.

Adjustable Heat & Louvers

Being able to control the temperature is also critical. Your heater should have heat mode adjustments, temperature controls or sensors, or a combination of the three. Adjustable louvers and vents will also aid in directing airflow, so a single spot in your gym isn’t overheated while the rest remains colder.

Running Cost

Electric heaters and gas heaters will all have running costs. What that cost is and how it affects your overall budget are what you need to be concerned with. Electric heaters need to be energy efficient and not overrun your electric bills. However, gas heaters can get expensive when you have to constantly refill or buy new tanks to keep the heaters running.

Warranty

Most heaters will come with a warranty that falls between 1 and 5 years. The higher-end models will have (generally speaking) longer warranties and better performance, but that also comes at a cost. If you need a temporary solution, this is less of a concern, but for a long-term investment, you may wish to know what is covered and for how long before you buy.

Price

Finally, the price of the heater will be an important factor as well. You will need to balance cost with performance and ensure you get the best deal for the money. Just because a heater is expensive doesn’t mean it is the best option for you, likewise with cheaper models. You don’t need to go into debt with your heater purchase, but it needs to perform as expected, too.

What Is the Ideal Temperature for a Garage Gym?

According to exercise physiologist and fitness director at Duke University Gerald Endress, and reported through NBC News, there is an optimal workout temperature. That range is between 68 and 72 degrees Fahrenheit.

This temperature allows the muscles to remain loose and capable without overworking to keep the body warm. It also allows your body to sweat as needed to stay cool during the workout without the risk of dehydration.

Insulating Doors & Walls – Worth Considering?

Certain heaters work best in adequately insulated and sealed rooms. However, it can pose a challenge because garage gyms aren’t known for being finished rooms with proper insulation. They often have large drafty doors and little or no windows.

Should you finish your garage to make it a better suitable environment? It will help, yes. However, the construction costs may be more than your budget allows. While a finished and insulated garage isn’t critical, it will help lower energy costs, utility fees and even help you maintain temperature longer.

The short of it is if you can afford to have your garages insulated, including the doors and windows, you should do it. If your budget doesn’t allow it, you can always use a higher-quality heater in the meantime.

People Also Ask (FAQ)

What type of heater is best for a garage gym?

Space heaters and portable heaters are generally the go-to options because they are less expensive than a permanently mounted or HVAC inclusive option. With a portable unit, you can put the heat right where it is needed, and larger garages will benefit from the portable capabilities.

How can I stay warm in my garage gym for free?

One of the best methods of staying warm is to layer clothing. Unless your workouts are an Instagram fashion show festival, it doesn’t matter that you are wearing two pairs of socks and three layers of sweat pants. Adding clothing layers to stay warm while not encumbering yourself or restricting movement is the best option to keep warm for free.

Why are garage gyms usually so cold?

Garage gyms are typically colder than other home gym rooms because garages aren’t usually insulated. While you can block drafts from doors and windows to prevent air movement, heat will transfer through the thin walls and ceilings unless the room is properly constructed, finished, and insulated.

How do I control the temperature in my garage?

Portable heaters, air conditioners, fans, and air circulation are the key to proper temperature control. These can be separate machines or appliances, or a more all-inclusive unit such as central HVAC equipment. You will also need to control drafts around doors and windows, maintain ventilation and have proper insulation.

Conclusion

Finding the right heater for your garage gym can be difficult. There are multiple styles, sizes, and types to research and discover. On top of that, you need to decide if you want electric or gas powered heaters and if they should be portable or permanent.

This article aimed to cover all the various needs and options to help you find the right type of garage gym heater. We also covered, rated, and reviewed the best heaters for garage gyms to give you a starting point. Hopefully, you know which option is best for you and what model you need.
