Best Electric Garage Heaters 120v / 240v For the Money: Reviews 2019

​​​Last year, we visited the Ortons to see what they had done with their garage. They had earlier asked for suggestions on how to organize their garage and were glad to show us the results.

When we got there, we were pleased to see that our plan had worked for them, but one thing grabbed our attention. The place was super cold! We asked them how they were coping working in such a low-temp environment, but they talked of something to do with “adapting” which didn’t seem like a fair excuse.

Mr. Orton even had a bad cold, and he admitted it might have been as a result of working late in such an environment.

If you’re here, we’re guessing it’s because your garage feels a little cold. Maybe you’ve even tried installing some form of insulation, but that has proven to be inadequate during fall and winter. If you’re living in a region whose temperatures are often on the low side, insulation is not enough.

Installing a garage heater is the best step to conquering the cold.

Don’t go anywhere. In this post, we’ll introduce to you some of the best electric garage heater 120v and 240v models and discuss ways in which you can make your garage warmer.

Things to Consider Before Buying the Best 120v / 240v Electric Heater for Garage

When the cold season comes, you want to be sure that your heater for garage will deliver. But choosing a powerful, reliable heater isn’t always easy. There are numerous brands and models, and if you’re not careful, you can get the wrong one.

To prevent that, we’ve listed a couple of considerations you should make when looking for a heater for your garage.

Mounting

Some garage heaters are mounted on the wall, others on the ceiling, and yet others are portable meaning they come with a stand and can be placed wherever the user likes.

If you want a fixed rather than portable unit, you’re better off getting something that is both wall and ceiling mountable. It’d help if you got a unit that comes with mounting hardware including a bracket.

For those of you who need optimal versatility, the perfect unit is one that is portable; a tagalong unit that you can place wherever you want.

Electrical installation

Some heaters are to be hardwired while others are to be plugged into a socket using a power cable. If you aim to get something industrial-grade that will heat a big space, it is almost inevitable that the kind of heater that suits you needs to be hardwired.

Again, hardwiring reduces the chances of overloading a fuse and blowing it, so it’s a preferred choice among workshop and garage owners. If you don’t have the needed wiring skills, be sure to have an electrician do it for you.

The benefit of purchasing a heater that plugs into an outlet is that the installation is pretty fast and simple, eliminating the need to get an electrician.

Also, keep it in mind that some machines require 120 volts while others require 240 volts.

Power source

There are two main power sources for space heaters – electricity and combustible fuel like propane or natural gas. While each has its risks, those that use combustible fuel present a bigger risk of inadertent fires.

Moreover, they can release fumes that are harmful to people and the environment. The necessity for extra venting might require you to pay more money for installation.

Electrical models are obviously safer and cheaper to install than the ones using combustible fuel. We recommend going for a model with overheat protection to reduce the risk of fires even further.

The size

The heating capacity is measured in BTUs, and for each square foot of space, you need at least 20 BTUs.

So, before getting a heater, you may want to consider the size of your garage in square feet. Just measure the length and the width, and by multiplying the figures, you’ll get the size in square feet.

Supposing you get the length and width to be 30 and 20 feet respectively, that is 600 square feet. We imagine that to be a 2-stall garage.

Multiplying 600 by 20, you get 12000 BTUs. That’s the minimum amount of heating you need for this space. Perhaps the model you’re considering to purchase offers 21000 BTUs or another figure greater than 12000. There’s nothing wrong with that as long as its temperature is adjustable.

Those are the main factors to consider but don’t forget to look at the construction, which denotes the durability. A heater made of stainless steel or other sturdy materials will last. Also, check the machine’s ease of use.

That aside, it’s time to look at the reviews.

How to Install an Electric Heater in Your Garage

As stated before, most garage owners prefer hardwired garage heaters because they allow them to operate other electrical tools without overloading and blowing a fuse.

So, we’re going to look at the method of installing a hardwired heater. Besides, installing models that are plugged into the wall outlet is straightforward. Let’s get to it.

Step by step process of installing a garage heater

Step 1: Get a heater that suits you

You don’t want to get a model that won’t sufficiently heat your garage. So, get a heater that has the wattage or the BTUs needed to warm up your space.

Multiplying the length and width of the garage will give you the size in square footage. Whatever figure you get, you should multiply it by 10 to get the wattage needed to warm it up or multiply it by 20 to get the minimum number of BTUs required.

The buying guide above should guide you on the other considerations you ought to make to buy the ideal space heater.

Note: in this example, we’ll use the NewAir G73 240 Heater.

Step 2: Gather the supplies

The items you might need include:

  • Utility knife
  • Marker
  • Tape
  • Wire connectors
  • Wire and ground-sheathed cable – most heaters require 10-gauge or bigger
  • Cable straps
  • Circuit breaker – most heaters need 30-amp or higher
  • Pliers
Step 3: Mounting
  • Hook the mounting bracket to the heater. Fortunately, the NewAir G73 comes with the mounting hardware, including the mounting bracket, the anchors and the bolts.
  • There are a couple of bolts on the side of the machine. Get them off and use them to connect the bracket to the machine.
  • On the side, you’ll also see some thumb screws, and you can use them to set the bracket at various angles.
  • Now, you want to attach the other mounting bracket to the wall, so go ahead and drill two holes in the wall stud. Use the provided lag nuts and washers to secure the bracket to the stud.
  • NewAir Provides a carriage bolt, and it’s got a carriage bolt with a square piece below the head to attach the bracket to the heater. Insert the bolt through the square hole on the heater’s bracket (from the bottom side) and insert the spacer.
  • Now insert the remaining free part of the bolt up through the hole on the bracket that is mounted to the wall.
  • Insert the star washer, the lock washer, and the 17-mm knot and tighten it, though not so much because you want the heater to be able to move a bit when hooking up the power.
Step 4: Wiring

For the NewAir G73, a 10/2 Romex wire long enough to run from the house’s breaker panel to the point where the heater will be installed will do. 10/2 means a 10-gauge wire and 2 shielded wires and a bare ground. The white wire is the one carrying current.

  • Strip the orange shielding back so you can get the wires through the fitting.
  • Open the electrical panel at the lower side of the heater and remove the electrical cables (the black and white).
  • Use twist-on wire connectors to attach the wires, making sure the black is hooked to the black, and the white is hooked to the white. But before that, be sure to insert the incoming cable into the plate of the heater’s electrical panel.
  • Once you’re done connecting the wires, use a wire harness tape to secure the connections.
  • When that is complete, push the plate with the connected wires into the heater’s panel and close it. Secure the bolts appropriately.
  • Go to the breaker panel and shut off the house’s main breaker.
  • Remove the bolts on the breaker panel to get to the breakers.
  • Strip the shield to the romex wire’s end to expose the individual wires. Remember, in this case, you need a current of 240 volts. Each of the two wires (black and white) is to carry a voltage of 120V.
  • Begin by finding a spot on the busbar for the ground wire and get the wire attached. Push it right in and tighten the screw.
  • The next step is to connect the breaker to the legs on the panel, but it’s more convenient to connect the wires to the breaker first. Remember, you need a breaker that will be able to handle the power needs of the heater. For the NewAir G73, and most other heaters, by the way, a 30-amp circuit breaker is needed.
  • Pop the wires into the holes at the back of the breaker. It doesn’t really matter which hole, because the wires carry equal voltage.
  • Now, pop the breaker in place onto the breaker leg.
  • Once that is done, it’s time to reinstall the panel cover.
  • And, you’re all done. Now you can turn on the main breaker and switch on the heater. If there are any issues with the wiring, its fuse will get tripped.

Final step – pop and beer or soda or whatever drink you like and enjoy!

Safety Precautions That You Need to Take While Using Garage Heater

Although electrical heating systems are a lot safer than the propane heaters and other heaters that use combustible fuel, exercising caution is always a good thing.

In order to understand how to ensure there’s safety, you need first to know the basics of how electric heaters work. Most units use a hot coil and a fan to dissipate the hot air.

Both the coil and the fan are typically enclosed in a cage, and they should stay that way to avoid accidents.

If kids or pets come into your garage, it’s better to mount the heater to the ceiling or high up on the wall where they cannot reach it.

If your unit is portable, be sure to place it on a flat, firm ground where it is stable. Also, be vigilant not to knock it over and ensure kids and pets don’t mess it with.

The area around the heater should be free of items like papers, clothes, and other combustible objects to prevent an accidental fire.

The U.S Consumer Product Safety Commission issues a few more safety precautions that space heater owners need to observe:

  • Ensure the plug is firmly secured to the outlet and don’t overload the outlet.
  • Don’t leave the heater on while going out.
  • Don’t plug the heater together with other high-wattage gadgets to the same circuit as that might cause overheating and potentially lead to a fire.
  • Keep the heater away from papers, beddings, furniture, and clothes.
  • Don’t use the heater if it is damaged.
  • Leave a free space of about 3 feet around the appliance.

Apart from observing these safety precautions, it’s advisable to buy a model with built-in safety features in the first place. Some of the features to look out for include:

  • Overheat protection
  • Auto shut-off
  • Stable base
  • Cool exteriors
  • UL certification – this is not really a feature but an assurance that the appliance has been manufactured with good safety standards.

When you buy your heater, look for the list of safety precautions in the instructions booklet. Read them and ensure you exercise them. Furthermore, read the instructions on use to be sure you’re handling the gadget properly.

Types of Electric Garage Heater

Space heaters can be categorized in two ways – by the manner in which they generate heat and by the portability.

By Heat Generation Style

Under this, we have 3 main types of heaters.

  • 1
    Radiant
  • 2
    Convection
  • 3
    Conductive

Let’s quickly see what each type is about.

Radiant

These use diathermic oil or other similar liquids flowing through a series of pipes for heat generation. As they don’t radiate heat through obstacles, they’re generally used for precise heating where the user wants to direct the heat to a particular area, like the workbench or something.

That means radiant heaters aren’t very effective for heating large spaces.

One advantage of radiant heaters is that they generate the heat quickly so if you need something to warm up your space quickly, a radiant heater will come in helpful.

Convection

There are heating elements in the heater, and when the air getting in comes into contact with the elements, it gets heated. These models heat the air slowly, but the effect lasts.

Though they are heavier than the radiant heaters, convection heaters are quieter. Some of them have a fan to help in the dissipation of the heat.

Conductive

Conductive heaters also use heating elements to generate heat. These elements are often made of mica or a mixture of chromium and nickel to convert electric energy into heat.

High portability is the main benefit of conductive heaters.

By portability

Under this, there are two main forms of heaters – portable and fixed units.

Fixed units are the kind that need to be mounted either to the wall or the ceiling joist using fasteners. These units are also often meant to be hardwired to the electrical system.

Portable units, on the contrary, have a stand and can be placed anywhere. Also, they’re meant to be plugged into a wall outlet rather than hardwired. If you don’t have wiring skills and you don’t want to spend money on paying an electrician, you might want to get a portable unit.

How to Take Care of a Garage Heater for Longevity 

The top heaters are built with sturdy materials, and their heavy-duty nature means the maintenance needed is minimal. Dust is, however, always a problem with heaters and thus cleaning is an important maintenance step.

The following cleaning tips should help you keep your heater working properly safe from dirt and dust.

Dusting

Dust the heater at least once per week to keep the dust from building up. While doing it, be sure to turn off the heater and allow it to cool down first.

Removing the grime

Food spills and other grime need to be removed to keep the heater in good shape. A damp microfiber towel and a little dishwashing liquid should do it. Remember, you’re dealing with an electronic so don’t pour liquids on the machine directly.

Vacuuming

If your heater has a grille or vent, then you ought to vacuum it on a regular basis to clear the airflow. A heater that has a fan attracts dust a little more than one that doesn’t, so if your heater has a fan, then you know how important it is to vacuum it.

Radiant heaters

Radiant heaters have a shiny heat-reflecting plate, and this needs to stay shiny for good performance.

Unscrew or unclip the grille protecting the plate then use a towel or vacuum to get rid of the dust. If the plate is very dirty, use a damp microfiber towel to clean it.

Dealing with rust

The reflector plate is susceptible to rust, and it’s especially in the risk of rusting if it is not dusted regularly. The key to protecting your heater from rust is cleaning.

If you see rust spots forming you can either use a rust remover spray or scrub it off using steel wool.

There are many different models out there, and each model might have some unique maintenance needs. So, check your user guide for instructions on maintenance.

In this section, we’re going to discuss some of the most common issues that cause space heaters not to work properly and their solutions. Let’s jump in.

The power

If your heater isn’t working well, the problem could be the power supply.

Fix

  • Check the connection in the breaker panel as well as the power cable or the wall outlet if the heater is plugged in there. Also, have a look at the machine’s switch and make certain it’s working well.
  • A problem with the power causes the fuse to get tripped, so check the circuit breaker. If the fuse is tripped, reset it and if trips again, then you know there’s a problem with the wiring. A blown fuse needs to be replaced.
  • Check the power cord for breaks and if there are any, replace it.

A problem with the thermostat

If the thermostat goes off or becomes stuck, loose, or faulty in any way, you might experience issues with the electric heater.

Fix

Inspect the thermostat knob. If it’s off, rotate it to increase the temperature. And in case the knob is stuck or faulty in some way, have a professional fix it.

Automatic shut off

Modern electric heaters are designed such that if there’s overheating, the heater just shuts off to protect the device’s components and keep the fire from erupting. But the feature can mistakenly cause the heater to shut off.

Fix

Disconnect the power and allow the heater to cool down for at least ten minutes before turning it on.
