In-depth Heater Reviews
1. Modine Hot Dawg
If you’re looking for an industrial-strength garage heater that can be used with either natural gas or propane, then you will love the Hot Dawg from Modine.
First of all, this is a highly reputable company, meaning that you can trust that you’re getting the best parts and materials. Secondly, you will be impressed by how well it can heat your garage.
What I like most about the Hot Dawg is it’s quiet and efficient performance.
- Power/BTUS: 45,000
- Square Ft Heating: 2000
- Thermostat Control: No, but it can be hooked up to one
- Easy Installation: Yes
- Safety Issues/Concerns: Requires ventilation; no oxygen depletion sensor
It can operate all day long, and it will never get irritating, and it won’t waste a lot of energy. In fact, this model is 80% efficient when producing heat, which is remarkable when you compare it to other natural gas heaters.
The other thing that I appreciate is the installation process. Unless you are really inexperienced at installing these kinds of things, you should be able to do it yourself without much trouble.
I would suggest hiring a pro to inspect the unit afterward to ensure that you didn’t mess anything up, but that will still be a lot cheaper than hiring someone to hook it up for you.
The only downside to the Hot Dawg is that it’s almost too strong. As such, the price tag is higher than most commercial or residential models, and it won’t work unless you have sufficient space.
While you can connect it to a thermostat to help regulate the temperature, it’s better when you have more room for it to work.
Otherwise, things will heat up super fast.
- Durable construction
- Easy to install
- High-powered heater
- Quiet operation
- Energy efficient model
- Heats up to 2000 feet
- Vents on the right or the left
- Mount to wall or ceiling
- Motor is built to last longer
- Can hook up to a thermostat
- 80% efficient
- CSA certified
- Low profile design
- Made in the USA
- Pricier than other models
- Industrial strength is not recommended for smaller spaces
2. Dyna-Glo RMC-FA60DGD
Next, we have a directional heater that uses a high-powered blower to distribute the heat evenly. This model is perfect if you need to keep a particular area hotter than others, or if you want a portable model that is also super powerful.
What I like about this heater is that it works quickly. You can feel the effects after just a few minutes, thanks to the directional system. Surprisingly, it works on an area of up to 1,350 square feet.
I was worried that it wouldn’t spread the heat that well, but it does so much better than I expected.
- Power/BTUS: 30-60,000
- Square Ft Heating: 1,350
- Thermostat Control: Yes
- Easy Installation: N/A (portable)
- Safety Issues/Concerns: No oxygen depletion sensor; hot surface
The downside of this heater is that it’s loud. The blower is much more intense than most heaters, so you will have to get used to it. Also, it can be a safety hazard if you don’t keep it out of the way, as the surface can get quite hot after a while.
Thankfully, it does have some built-in safety features.
First, if it gets knocked over, then it will shut off automatically. Also, if it overheats, it will turn off so that it can cool down.
I also appreciate that it comes with an adjustable stand so that you can have some variety in how you position it.
- Durable construction
- Easy to use design
- Compact and portable
- Fast and efficient
- Stay cool carry handle
- Adjustable height for convenience
- Variable temperature controls
- Heavy-duty motor
- Continuous electronic ignition
- CSA certified
- Tip over shutoff built in
- 10-foot propane hose and regulator
- Powerful blower for even distribution
- Noisier than other models (due to the blower)
- Ignition doesn’t turn on immediately (it takes 30+ seconds)
3. Farenheat Industrial Electric Heater FUH724
The Fahrenheat Industrial Electric delivers consistent heat to the garage or anywhere else you might find yourself needing a little extra warmth.
Ceiling-mounted for ease.
Instead of taking up precious floor space with your unit, simply attach this Fahrenheat unit to the ceiling via the included mounting bracket and open up your floor space once again.
This heater works best when mounted in a corner to provide even hearing to your entire area.
By using the adjustable downdraft on the front of the heater, you can point the warm air anywhere that you’d like it to go. Whether you want direct heat over one section of your garage or need even heat throughout, you can customize your heating to get the temperature comfort that you need.
- Ceiling bracket gives you the option to semi-permanently mount the unit anywhere you want
- Safety features include automatic shutoff for an overheating unit
- Epoxy finished to resist corrosion
- Adjustable downflow gives you heat where you need it most
- Can have difficulty adequately heating larger spaces
- Doesn’t have as consistent heat as a propane model
- Uses a considerable amount of electricity
- Can be noisy and disruptive at startup
4. Mr. Heater Portable Big Buddy Propane
This heater warms up to 400 square feet, which gives you plenty of space to putter around without leaving the heating zone.
With a powerful combination of radiant and convection heating, the portable Big Buddy gives you the best warming option for your space.
You can adjust the heat levels with an intuitive settings control to meet the temperature needs of even the bitterest winter days.
The Big Buddy has a diminute size that makes it a cinch to tote around your workspace or from place to place.
With an integrated easy-carry handle and cord bays for external components, this unit is self-contained and simple to maneuver.
Safety features built right in.
In an effort to protect you and your property, the Big Buddy has integrated safety features that keep it from causing and fire or gas related problems. An automatic low oxygen shutoff monitors the air and turns the machine off when oxygen levels are too low. And an accidental tip-over safety shut off powers the device down if it’s tipped or knocked over.
- Provides steady warmth for up to 400 square feet of room
- Four levels to suit your comfort level and outside temperature needs
- Can be battery operated of plug in via ad 6-volt A/V adaptor
- Compact and self-contained
- Uses a large amount of propane
- Some users report problems with connection hoses breaking or other incompatibility issues
- Sometimes difficult to light
- Parts may break easily
5. Cadet The Hot One
For those of you who don’t need a massive heater like the Hot Dawg, you may prefer a more subdued model like this one from Cadet.
Dubbed “The Hot One,” this machine is perfect for most small spaces. It works well as an area heater, and it can sufficiently warm a garage up to 600 feet.
The portability and control panel for this heater is its best qualities. It comes with a thermostat dial so that you can adjust the temperature between 40-85 degrees.
It will also wait until the unit is sufficiently heated before activating the fan, which is a nice touch. It has three modes: on, off, and auto, which makes it even more suitable for area heating.
- Power/BTUS: 10,000 BTUs, 5,000 Watts
- Square Ft Heating: 600
- Thermostat Control: Yes
- Easy Installation: N/A (portable)
- Safety Issues/Concerns: Requires a 20 amp outlet
What I don’t like about the Hot One is that it doesn’t come with a carrying handle.
So, if you have to move it while it’s on, you will need to put on oven mitts or something as the shell can get scalding after a while.
Also, if it overheats, you need to reset it manually by triggering the button on the side.
The only way to do this is with something small and pointy, so be prepared to try sticking a sharp pencil or something into it. Just wait until it’s cooled off a bit before you do anything.
Overall, this heater is excellent for most small, one-car garages, and it will be a good addition to places that don’t need a ton of heat on a regular basis.
Also, you will need a 20-amp outlet, so be sure to check your electrical capabilities before turning this thing on. Since it uses 5000 watts, it can blow your breaker really easily.
- Durable powder coated steel frame
- Compact and easy to use model
- Perfect for spot heating and small spaces
- Automatic shutoff for safety
- Wall mount included
- Long six-foot power cord
- Easy to use controls
- Thermostat control (40-85 degrees)
- Manual reset option
- Fan delay built-in
- It can overheat relatively easily
- You have to manually reset every time it overheats
- No carrying handle provided
6. Lasko 751320
An excellent option for heating on a budget, the Lasko 751320 ceramic tower heater boasts convenient functionality while staying well below the cost of many other quality garage heaters.
This unit supplies enough heat to maintain comfort in spaces up to 300 square feet in area. With built-in safety features and adjustable heating options, this Lasko offering gives you preferential control and peace of mind.
The lightweight, portable design and streamlined construction let this unit heat any room you need without getting in the way.
- Power/BTUS: 1500 watt/5000 BTU
- Square Ft Heating: 300 sq. ft.
- Thermostat Control: Yes
- Electronic controls
- Adjustable thermostat
- Built-in timer
- Remote control
For the investment, it’s hard to deny the overall usability, convenience and quality. Backed by a 3 year warranty, this heater will give you plenty of consistent performance.
The Lasko 751320 is a great value that offers a versatile array of heating automation options. It has a variable temperature control ranging from 60 – 85 degrees and an auto-off timer. It takes control for you, giving you the temperature you need, when you need it.
This model was built on a focus of safety and quality. Ceramic space heaters are less prone to starting electrical fires because they don’t get overheated. The Lasko takes that inherent safety a step further by adding auto shut-off if it exceeds a certain temperature or tips over. You also don’t have to worry about getting burned from accidental contact thanks to the cool-to-the-touch exterior.
The biggest downsides to the Lasko 751320 are the power and the temperature control. This model is good for heating 300 square feet. It will definitely be hard to get comfortable if you’re trying to heat a larger area. The oscillating feature does direct heat over the entire area when placed strategically but if you have an area larger than 30’ x 10’, you should look for a more powerful option.
The temperature control is a nice feature of this heater’s thoughtful overall design. However, working on a range from 60 – 85 degrees at 5 degree intervals, it can be hard to find the exact perfect temperature sometimes. For many of us, that ideal temperature rests right in the middle, making 70 feel too hot and 65 feel too cold.
- Compact, lightweight and portable
- Oscillator evenly disperses heat
- Configurable temperature and timer
- Remote control operation
- Variable temperature settings
- Low and high heat options
- Overheating and anti-tip protection
- Cool-to-the-touch exterior
- Convenient carrying handle
- Thermostat only programmable at 5° intervals (60, 65, 70, 75, 80, 85).
- Possible plastic smell upon initial use.
Types of heaters
Obviously one of the most important considerations for choosing your garage heater is what type of heater you want in your space. Do you have a large space that needs consistent heating each day? Or are you working in a smaller garage and only a few hours each weekend?
Thinking through these questions will guide your decision process to help you settle on a heater to suit your needs. Whether you plan to use it often or infrequently, as well as your unique garage setup, will dramatically impact your heater choice.
A forced air heater works by blasting hot air into a space to provide warmth inside. This type of heater can be powered by electricity or gas, depending on your heater type and home setup.
Gas units are cheaper to operate than electric ones are, though electric units are generally a little easier to install. Additionally, you often need to check for local guidelines and have a professional install your gas unit to keep things on the legal side.
Pros of forced air heat.
- Can choose fuel type, depending on your home’s setup
- Many options for size and mounting style
- Different price points can help you stay within your budget
Cons of forced air heat.
- Required professional installation for propane setup
- Uses blasts of air that can blow dust around or provide an otherwise unsuitable atmosphere for getting work done
- Running an electrical unit can be very expensive
Radiant heaters use strong reflectors harness infrared heat and direct it outward and into your garage. These heaters provide steady warmth and are best mounted out of the way to keep from accidentally bumping into them.
Radiant heaters offer consistent and enduring warmth that can cut through even the coldest temperatures. Like forced air heaters, they can be powered by gas or electricity and come in a variety of sizes, price points, and mounting styles
- Still heat keeps dust and other particulate matter from being stirred up
- Consistent heat provides steady warmthVery warm heat for even the coldest climates
- Options for gas or electric fueled heat are available to suit your home’s fuel source
- Very hot heat can get uncomfortable or dangerous, if proper safety precautions aren’t observed
- May offer spotty heat – making one area too warm and other not warm enough
- Larger spaces may require multiple heaters for effective heating
Convection heating works similarly to the average oven – by utilizing a hidden heating element or small flame to warm air inside of the unit, which rises naturally and escapes the unit to warm the room. Convection units are typically cheaper and portable, though higher end mounted models are available.
Do you want to have the freedom to move your heater or have it stationary in one location? Your mobility choice will influence whether you can keep your heater in a single spot or take it with you from workstation to workstation.
Mounted units attach to the garage ceiling or wall and offer consistent heat from one location. Often, they have adjustable temperature settings and down events to give you heat where you need it most.
- Free up valuable work space on the floor or tables
- Closer to professional level and keeps pesky cords off of the floor and out of the way
- Integrated directly to your home’s fuel source, whether gas or electricity
- Can be adjusted by moving vents to suit your needs
- No freedom to move heat to wherever you want or need it most
- Limited adjustability – often faces a single direction with no pivot
- Requires professional installation and/or approval of your local zoning board
- More expensive than portable models
Portable heaters offer exactly what you think they might – portability. Generally, these electric units plug right into the wall of your workspace and can be transported from location to location.Gas powered portable heaters do exist, though they often aren’t rated for use indoors – obviously, the above-mentioned Dyna-Glo RMC-FA40DGD is an exception to that rule.
- Easy to move and use wherever you need it
- Provide heat in a single area, rather than heating the whole space
- Usually much cheaper than mounted model
- Doesn’t require professional installation
- Cords may get in the way and could cause workspace dangers
- Heater footprint takes up valuable square footage
- May cause uncomfortable and inconsistent heating throughout the garage
- Some cheaper models may not work as expected
The type of power that you choose depends both on personal preference and your home fuel setup.
Electric heaters utilize your home’s electricity to run, either by plugging in or through hard-wiring. Electric units are often inexpensive, though they do impact your monthly energy costs during colder months when they’re in us
Most propane units are tied directly into your home’s gas line, to utilize the gas power you already have there. Some portable units can be powered with small, portable propane tanks, but typically this is a cost-ineffective way to fuel them.
Natural gas powered heaters also tap right into your home’s natural gas line to draw their energy. Over time, these units are cost effective, since they utilize a small amount of a utility that you already pay for.
Obviously with such a potentially dangerous device as a garage heater, safety must be a top concern. When choosing a garage heater, consider the safety features that each unit has to offer.
Tip over switch.
If the heater is accidentally tipped or otherwise falls over, the tip-over switch shuts off the unit immediately.
This keeps heating elements from accidentally contacting material that they should not or any broken components from causing improper function of the heater itself.
Overheat protection is an automatic shutoff feature that turns the heater off if sensors indicate that it has exceeded a certain heat threshold. This keeps a unit from running too hot and accidentally starting a fire or melting certain onboard components
Cool touch is just as it sounds – a heater that is cool to touch. Instead of having exposed heating elements or a body that runs super hot during operation, a cool touch heater can be brushed against or run into without causing burns or other injury.
What you should know before buying a unit
Knowing your own garage is key to understanding what type of heater will work for you. To determine the heater you need, answer the following questions:
- What work are you doing?
- How many people are working with you?
- Are you working alone?
- Does your home have propane or natural gas?
- How often do you use your workspace?
- Is physical square footage an issue?
- How cold are your winters?
Are garage heaters safe?
Electric heaters are safe if they count with tip over switch, overhead protection and cooltouch, but as “risky” as any other electricalpiece of equipment. You must follow the traditional safety measures you would do for any other such item.
Propane garage heaters are safe if they are designed for indoors and count with an exhaust line properly installed. You should not use an outdoors propane heater inside your garage.
How big a garage heater do I need?
Majority of manufacturers will give you a good estimate of how many sq feet is the garage heater able to heat properly. You need to know how big is your garage first. For the average 2-car garage, 5000w or 60k BTU should do.

When comparing all of these heaters, I have to say that my top pick is the Hot Dawg from Modine. I love the fact that it’s got industrial-strength performance and that it’s easy to install (relatively speaking).
Plus, it’s quieter and more efficient than the competition.
Overall, the Hot Dawg is more powerful and more reliable than almost anything else we’ve seen.
