What is a Garage Heater?

Without central heating and insulation, garages cannot retain heat. As a result, they become uncomfortable during cooler temperatures. A garage heater (also known as a shop or zone heater), solves this problem by warming the space so you can use it—even when it is cold outside. Unlike room heaters designed for the home’s interior, a shop heater delivers more power to heat poorly insulated areas. Some units are portable, while others mount to the wall or ceiling. They are available in multiple sizes and powered by various sources energy sources.

How do Garage Heater Work?

Best Garage HeaterWarm air is lighter than cold air. Therefore, warm air rises and cold air falls. When cold air and hot air occupy the same space, it moves quickly causing drafts or hot and cold spots. An air handler, like a garage heater, helps the area maintain a steady, comfortable temperature.

Best garage heater may require electricity, gas, water, oil, or a combination of sources to function. Regardless of the energy source, the underlying principle is the same: heat flows from the appliance to increase the air temperature in the garage. The transfer of heat occurs when the machine is turned on to warm a heating element inside the unit. As the appliance warms up, the heating element converts the energy into radiant or convective heat. Radiant heat warms bodies and objects in its path. Convection heat seizes on warm air’s ability to rise and increases the air’s temperature as it moves. The number of watts or BTUs (British Thermal Units) the unit has determined the heat output.

Types of Heat

Convective heat moves liquids or gases to transfer heat. Most convection heaters have a fan that blows air over a heating element and circulates throughout the space to provide warmth. As hot air rises and moves toward the ceiling, it expands, pushing the cold particles down and toward the heater. When the air at the top of the garage starts to cool, it falls and passes through the heater again.

This cycle continues, filling the space with warmth. Most units have a thermostat, which allows the heater to shut itself off once it senses the air has reached a preset temperature. If the thermostat detects a big drop in temperature, it will cause the unit to power on again.

Radiant heaters emit infrared rays that travel directly to a targeted area. Unlike convective heat that using a fan to move air, the units contain a tungsten filament or another conductor. It is similar to sitting in the sun. In the sun, your skin and clothes absorb the heat from the sun’s rays. To feel the warmth the unit generates, you need to stand or sit in its path. Otherwise, it will feel like you are sitting in the shade.

Heating Elements

Elements of Garage HeaterThe heating element housed inside the appliance determines the type of heat it will produce. It may be made of metal, tungsten or ceramic. In some heaters, you will notice the element glowing from the heat. Other units remain concealed by a protective shell.

Metal: Nickel and chromium are great resistors of heat and most metal elements contain an 80/20 combination of the materials. They have a melting point of 2550 degrees and produce convective heat.

Ceramic: Ceramic plates are self-regulating. When the panels reach their heating limit, they plateau, so you don’t have to keep adjusting the temperature. Ceramic material heats quickly and supplies uniform heat. It also generates convective heat and has a melting point of 2030 degrees Fahrenheit.

Tungsten: This conductor is the same element used in incandescent light bulbs. Generally the component is housed in quartz or glass to give off radiant heat. Best garage heater with this element have a reflector that directs the focus of the heat. Tungsten begins to disintegrate at 6192 degrees.

Energy Sources

Garage Heater ApplicationsThere are different sources of energy needed to power a garage heater. Knowing your energy sources can help you keep the area at a pleasant temperature. Here's a brief overview of each and some concerns you may have to address.

Electricity: Electricity is perhaps the safest and most efficient heater to use. Not only do electric heaters warm spaces quickly, but also electricity uses all of its energy to create heat. Still, you need to make sure that the garage is wired correctly to hold the unit’s power without throwing the breaker.

Gas: These appliances warm the air by gas combustion. Most units operate by using natural gas or liquid propane. Since gas is flammable and releases carbon monoxide, you will need to take a number of safety precautions if you choose this type of heater. Gas space heaters may be flued or fluid. Fluid space heaters require ductwork to push harmful fumes outside through a vent.

Unflued models do not and are not recommended for indoor use. Gravity vented models are also available. With these units, the heater uses the air inside the garage for combustion. The by-product still must go through a flue to the outdoors.

Oil: These units also operate with electricity but need oil as a buffer. The oil takes a long time to heat. However, once they reach a comfortable temperature, they continue to dispense heat even when the unit is in the off position.

Water: The home’s hot water tank is used to produce heat from the hot water into the air in the garage. If you live in a region where temperatures reach below zero, there is a chance for pipes could freeze.

Advantages and Applications

For many, garages double as an extra space for performing activities outside the home. DIYers use the space for projects. Large families use it as a recreational area. Sports fans use it to entertain. However, cold temperatures can put projects on hold and ruin the fun. Thanks to best garage heater, you can use this bonus space—even when the temperatures drop. Read on to learn how you can stay toasty in your garage.

Benefits

Works Quickly: Electric models start to heat up within a minute after turning them on.

Keeps You Warm For Hours: Infrared units continue to provide heat after turning them off.

Space-efficient: Compact and mounted designs leave you with ample space for work and play.

Provides Comfort: Having a garage heater allows you to occupy the garage without wearing extra layers of clothing to stay warm.

Frees the House: Keeping the garage warm during the winter gives you extra space for kids to play.

Low Maintenance: Simple designs make it easy to clean. With routine maintenance, the durable units last for years.

Protects: Cold temperatures can cause some items to contract and expand when the temperature rises. As a result, delicate parts can become damaged. A heater will keep condensation from forming, so components remain functional.

Versatile: Don’t let the name garage heater fool you. This versatile unit works well in other spaces, like guesthouses, barns, and sheds, too.

Uses

Where to use Garage HeaterRooms Built Over the Garage: Areas constructed over the garage may have cold floors if they do not have proper insulation. Since heat rises to the highest point in a building, a garage heater can remove the chill from stepping onto the floor without shoes.

Keep Vehicles From Freezing: The primary purpose of a garage is to house a vehicle to prevent the elements from ruining its paint. However, when you add a garage heater to the structure, it helps the car run more efficiently by keeping fluids flowing, preventing locks and doors from freezing and leaving seats at a comfortable temperature.

Mechanic’s Workshop: Whether you need to rebuild a muscle car or fix a clunker, wall, ceiling a wall or ceiling mount unit will keep you warm without getting in your way.

Recreation: Placing a heater in the garage frees up space inside the home for playing a game of pool, or creating music with your band. Consider a unit that combines radiant heat and fan-forced technology to spread the warmth.

Man Cave: If you need a place to retreat after a hard day’s work, adding a radiant garage heater will make the place a nice little getaway from the daily grind.

Woodworking: With a garage heater, you don’t have to bundle up while working on a project in your garage. The unit will keep you and the space warm, so you can work comfortably and productively. Stay away from fan-forced units. You don’t want dust and wood chips flying through the air.

Types of Garage Heater

Best garage heater is suitable for cold garages, workshops, and sheds. Depending on the size of the area, and the model you choose, they can heat the space quickly and efficiently. However, before you can find a suitable unit, you need to know the benefits and be aware of the drawbacks of the different types of heaters. You will notice that some of the same terms used to describe heating technology are also used to define the type of heater.

Fan-Forced Garage Heater

Fan Forced Garage HeaterThe main component of an air-forced heater is the fan. Some units operate strictly on electricity and other heaters need both gas and electricity to work. One of the major benefits of these types of heaters is that the fan helps boost the heating process so spaces warm quickly.

Gas models require a supply of liquid propane or natural gas. You will also find units that operate with diesel or kerosene gas. A spark or flame ignites the flame as it flows through the gas valve to a heat exchanger. Once the heating element reaches the temperature you set on the thermostat, the fan blows warm air into space. The by-products of the combustion go out of the garage through a vent pipe. A clean air chamber is recommended to prevent fumes and dust from rising in the air.

On electric machines, all the energy produced from the electricity is converted to heat. It may have a ceramic, metal, or tungsten heating element.

Fixed models come equipped with a thermostat, allowing you to choose the exact temperature you want to heat the garage. Look for appliances with steel bodies as opposed to plastic ones to avoid mishaps if the unit malfunctions.

Pros

  • Provides a rapid blast heat
  • Heats all spaces evenly
  • Electric models are one hundred percent energy efficient
  • Available in compact, portable designs
  • No need to replenish the fuel supply on natural gas units
  • Some models have a fan-only option to circulate air when it is warm outside

Cons

  • Fan noise can be distracting
  • Blows dirt and debris around the garage
  • Requires more maintenance than electric models

Infrared Garage Heater

Best Infrared Best garage heaterInfrared best garage heater is like mini suns. These heaters provide rapid rays of radiant heat to the coldest and closest objects in the line of its heat waves. They can be powered by electricity, gas, or oil.

Hot temperatures are produced via a ceramic surface or steel tube. The heated surface emits infrared radiant energy into the garage. Reflectors inside the unit direct the heat to people and items the path of the heat rays. As items and bodies absorb the heat, they help increase the temperature of the things around them. The air surrounding individuals and objects also absorbs some of the heat to make the space warmer.

These units feature an enclosed combustion chamber and barely create noise. Unlike other types of heaters, infrared appliances do not add pollutants or reduce the humidity and oxygen levels in the garage. However, they can get very hot. Additionally, the temperature can be uneven, resulting in a warm face and cold feet.

Pros

  • Not affected by drafts
  • Heats the entire room
  • Does not disturb air quality
  • Delivers immediate, direct heat
  • Quiet operation

Cons

  • Must be in close proximity of the unit to feel the heat
  • Can leave hot and cold spots
  • The unit is capable of getting extremely hot and can cause severe burns if touched accidentally

Gas Garage Heater

Best Gas Best garage heaterGas heaters can be vented or unvented. Vented units mount to a wall or the ceiling and have flues to direct exhaust fumes outside the structure. Vent-free models have a fan inside the unit that uses the air inside the garage for combustion. Most unvented best garage heater have an oxygen-depletion sensor that shuts off automatically if the oxygen drops to harmful levels. Even so, they are best suited for outdoor use and should not be operated inside a closed garage. There are three options available: natural gas, liquid propane, and kerosene.

Natural Gas: These fixed units connect to your home’s natural gas line.

Liquid Propane: Available in fixed and portable models, these units come equipped with an electronic fire starter similar to what you would find on a gas stove. A few units require the use of a match to light the flame.

Kerosene: Portable kerosene heaters feature a soaked wick that burns the kerosene. Unfortunately, they emit a strong odor.

Pros

  • Dispenses powerful heat
  • Heats two and three car garages quickly and efficiently
  • Most models come equipped with mounting brackets, a thermostat, and safety features
  • Units that don’t require electricity continue to supply heat in the event of a power outage

Cons

  • Requires adequate clearance and proper ventilation
  • Poses a higher risk of fires and other hazards than other types of heaters
  • Not recommended for garages that store paint and wood

Ceramic Garage Heater

Best Ceramic Best garage heaterThese best garage heater work on the convection principle and feature a ceramic element to heat the air. Furthermore, they are very efficient and operate using electricity. As the ceramic plates heat up they warm aluminum baffles. Most ceramic units are portable and consume less power than other types of electric heaters. They are available with and without a fan to help distribute the warm air.

Ceramic best garage heater are safer to operate than other types of gas heaters. They do not produce sparks or create a safety hazard if the element malfunctions. Additionally, the unit has a cool housing, minimizing burn risks.

You will find this model with a number of convenient features such as multiple heat settings, digital thermostats and remote controlled. Additionally, they come equipped with safety features like a shut-off sensor and timer. Overheat sensors monitor the amount of heat coming from the unit and turn off if the heater reaches an excessive temperature. Units with timers allow you to set the heater to run for a fixed amount of time.

Pros

  • Provide constant heat
  • Doesn’t get hot enough to pose a fire hazard or burn risk
  • Does not emit fumes
  • Temperature controls allow you to choose between low and high heat

Cons

  • Can be quite noisy when operating at full speed
  • Best suited for small areas

Oil-Filled Garage Heater

Best Oil Filled Garage HeaterIn terms of style, oil-filled best garage heater resembles an old-fashioned radiator with columns of stacked metal fins. Instead of steam, however, it operates using electricity. The electricity triggers a resistor, which warms up the diathermic oil. The liquid remains sealed in the unit and flows through a channel, warming the fins as it flows. The surrounding air absorbs the heat through the convection process. This cycle continues until the garage is filled with warmth.

It takes the electricity a while to warm the oil. However, once it heats up, it continues to provide warmth long after you turn off the unit. They are ideal for days or nights when you plan to stay in the garage for an extended time.

Since the unit does not have a fan, you don’t have to worry about dust flying around the garage. Select models have a tight seal to prevent spillage and automatic shut-off technology in case of the unit tips over. Small heaters come equipped with carrying handles and larger models have wheels for easy transport and positioning.

Pros

  • Silent operation
  • Consume little electricity
  • Long-lasting heat
  • Excels at heating two and three car garages

Cons

  • Costly
  • Slowly heats the space
  • Hot to the touch
  • Heavy and difficult to move

Mica-thermic Garage Heater

 Top Micathermic HeatersMica-thermic heaters produce a combination of convective and radiant heat. Instead of oil, mica panels (sheets of stone) cover the heating element to warm the space. Mica is an excellent heat conductor. When it reaches a specific temperature, it generates electronic rays to the furthest point of the room. The effect is similar to what you would experience when sunlight enters the room, supplying soothing radiant heat. They retain the moisture in the air, keeping it comfortable.

These units warm up quicker than their oil-filled counterparts do, but they also cool quickly. Typically, mica-thermic best garage heater have a slim profile. Some heaters feature wheels and others mount to the wall.

Pros

  • Warms large areas without the use of a fan
  • Silent operation
  • Does not recirculate dust through the area
  • Consumes less energy
  • Does not overheat
  • Stable

Cons

  • Not effective in high draft areas

Hydronic Garage Heater

An electric fan drives the hot water from your home’s boiler through a radiant heating element and pushes warm air into the garage. Most units operate with a thermostat, allowing the heater to run long enough to bring the garage to room temperature before shutting off.

These units are available in with horizontal or vertical louvers. Generally, horizontal models are positioned on a wall to blow warm air into small spaces. In contrast, vertical units mount to the ceiling and cover large areas.

Pros

  • Uses your existing hot water system
  • Works with gas, solar or electric hot water energy sources
  • Does not require extensive ductwork
  • Near-silent operation
  • Generates comfortable heat

Cons

  • Lines can freeze, causing the unit to malfunction

Baseboard Garage Heater

Top Baseboard Best garage heaterBaseboard heaters sit low to the ground and range from 28 inches to 96 inches wide. Electric units work through the convection heating principle and circulate air throughout the space without the use of a fan. Both portable and mountable models come equipped with a cut-off mechanism to prevent overheating. The mountable heaters have to be hardwired to your home’s electric system. Some heaters operate using the hydronic principle and require to hook up to a hot water system. Portable units resemble fixed floor vents, but they are freestanding. A pair of sturdy feet keeps the heater in place.

Pros

  • Ideal for mechanics
  • Units can sit side by side to cover large areas
  • No fan to create the dust-up
  • Quiet
  • Easy to maintain

Cons

  • Most fixed units require the purchase of a separate thermostat

Review Method

Review Method of Best garage heaterOur garage heater test aims to meet consumer expectations. To do this, we evaluated buyers’ comments and noted their pleasure or displeasure with the garage heater they purchased. From there, we assembled a list of manufacturers that customers identified as delivering on their promises. To verify our research, we examined space heater tests conducted by independent agencies. Most of the professional tests that we came across concentrated solely on space heaters for inside the home. Therefore, we studied the specifications for different best garage heater, read expert opinions, and watched installation videos to gauge each model’s performance and capabilities. While comparing professional tests with user feedback we identified three areas to focus our research: heat output, temperature settings, and safety features. Using the above criteria, we narrowed down the list to find the best space heaters for your garage.

Heat Output

For this garage heater review, we analyzed the various types of fuel sources and heating technologies to find out which units offered sufficient heat to warm a two or three car garage. The best heaters warm up quickly, distribute it evenly, and retain the heat after the unit is shut off. Then we verified the data with test results from independent labs. To examine the output, experts tested the units’ effectiveness in producing heat within 15 minutes.

Temperature Settings

Nearly all buyers agree that having control over the heat output is essential. Most units in our review come equipped with a thermostat and dial to adjust the heat output from low to high. However, some units lacked precision. While analog dials are more durable and easier to operate, heaters with digital thermostats shut off automatically when a preset temperature was reached.

Safety Features

More importantly, we looked at the specs of multiple models to see if they were equipped with cut-off mechanisms for overheating and tipping. Furthermore, we examine how the heating element was housed to prevent curious fingers from getting burned, as well as if the unit was cool-to-the-touch. Test performed by Underwriters Laboratories (UL) show that ceramic-plate heaters offer the most reliable form of overheat protection.
Overall, the best garage heater has UL certification, adequate safety features and:

  • At least 3000 watts of power
  • Heat within minutes
  • Cool-to-the-touch
  • Have simple controls
  • Operate quietly

Factors to Consider When Buying a Garage Heater

The first thing you need to consider after choosing a heat source is to decide if you prefer a fixed or portable heater. Moreover, you will need to assess the size of the garage and heat capacity. Ask yourself the following questions, then read on to learn about other factors you should consider when buying a garage heater.

  • Will you need to heat the garage all winter, or only at specific times?
  • Is a thermostat necessary to control fluctuating temperatures?
  • Will you need to move the heater from place to place?
  • Do you need to direct heat to a particular area in the garage?
  • Is there a safe place to mount the heater?
  • Will you need to heat the garage if there is a power outage?

Portable vs. Fixed

Infrared HeatersDepending on the size of your garage and what you will use the space for, you may desire a movable or permanent unit. Fixed units may require hardwiring and the help of a technician.

Portable: Portable units offer a quick set up. All you need to do is place the unit in a safe location, plug the unit into an outlet and turn it on. If you want an appliance that you can take from the garage to another location, consider a portable garage heater. If you prefer freedom from plugs, try a portable liquid propane heater.

Fixed: Unfortunately, fixed models tend to be a little more complicated to set up. In fact, some units require the expertise of a professional. With electrical units, you have to connect the unit to a permanent circuit, mount it to the ceiling or wall, and comply with local and national electrical codes. Natural gas heaters connect to your home’s gas line. They emit fumes and gases, so they must be vented to prevent harm.

If you will only use the heater occasionally, a plug-in model will suit your needs. On the other hand, if you use the space as a work or recreational area, consider purchasing a hardwired unit. Before you do, though, verify that there is enough clearance if you intend to install the unit on the ceiling or wall.

Styles

Wall Mount: This design can be placed high near the ceiling or at eye-level to provide warmth while you work. They are perfect for garages that are used as playrooms for kids.

Ceiling Mount: Ideal for garages with limited space, the ceiling mount unit usually features an articulating arm or adjustable louvers to allow you to angle the heat where needed. They can use natural gas or electricity.

Freestanding: These models offer portability, allowing you to place them practically anywhere on the garage floor or stable table. Freestanding units are not recommended if the garage is frequented by small children or pets.

Heat Capacity

Heat CapacityMany manufacturers list how many square feet the gas heater is expected to cover. Still, you will need to account for the type of climate in your region. If the unit is too small, it will not provide sufficient heat; too large, and the heat may become unbearable. You can also determine the heat capacity by calculating the watts or BTUs.

Wattage: The number of watts indicates the rate of speed a heater can transform electric energy to heat. You will need 10 watts of power per square foot of space. For example, if the garage is 700 square feet, multiply the number by 10. The answer 7000 is the number of watts you will need to heat your space.

BTUs: This unit of measurement, known as British Thermal Units refers to the power a gas-powered heater can produce. You will need approximately 45,000 BTUs to heat a two- car garage and 60,000 BTUs if the garage houses three cars. BTUs are also used to measure the intensity of infrared heaters.

Temperature Rise: To make sure the garage heater can reach a comfortable temperature, you have to subtract the normal temperature outside the garage from the desired temperature inside the garage.

For instance, the calculation for an interior temperature of 65 and an exterior temperature of 35 degrees would be 65-35=30. The time it will take the unit to increase the inside temperature by 30 degrees will depend on the watts or BTUs as well as the type of heater chosen.

Safety

Garage Heater Safety MethodMake sure your garage heater bears a United Laboratories (UL) certification. Units with the UL symbol have been tested to meet safety standards. One of the most significant safety features is a mechanism that shuts the unit off if it tips over. Other safety features include:

Automatic shut off: Units with this mechanism integrated into the design shut down if the unit gets too hot. It reduces the likelihood of fires and prevents the heater from overheating.

Overheat Protection: If you run the appliance for extended periods, it may overheat. With this safety feature, the heater will shut itself off to prevent damage that may lead to a fire.

Tip-over Switch: If you opt for a portable garage heater, it is essential that it comes equipped with a device to shut off the appliance in the event it tips over.

Long Power Cord: Safety experts warn against using an extension cord with a heater. Look for units that have a cord that is at least 6 feet.

Oxygen Depletion Sensor: You will find this device on gas-powered heaters. The appliance will shut off if oxygen levels become too low.

Cool-to-the-Touch Housing: This feature keeps you from burning yourself if you accidentally bump into the unit.

Finger-Protective Grates: All it takes is a second for the glow of a heater to tempt inquisitive minds. If you have small kids who frequent the garage with you make sure your heater has this feature.

Warranty

Warranties vary per manufacturer. Some manufacturers will repair or replace defective parts from 90 days to a year. Generally, more expensive units have a longer warranty. Keep an eye out for the list of exclusions. If the unit is neglected or not installed in compliance with instructions and local codes, the manufacturer is not obligated to honor the warranty.

Online vs. In Store: Where to buy a garage heater?

Whether you buy online or at a brick-and-mortar store is a matter of preference. Still, each shopping experience offers unique benefits and challenges. Below we give you an idea of what you can expect when shopping for a garage heater online and at a retail store.

Selection

Buy Best garage heaterWhen you shop at a physical location, you can observe the actual size of the heater. In addition, you will also have access to store associations who can answer any questions you may have. However, if you have a specific model in mind, and it is not available, you will have wasted a trip. Even if the associate can locate the model for you at another store, you will have to wait for the heater to arrive or go to another store to obtain the appliance.

Online shops have an extensive inventory. You rarely have to worry about your choice being out of stock. In fact, you will know immediately if it is available once you put it in your online shopping cart.

Price

Along with a varied selection, you will find that the prices online are lower than at a brick-and-mortar store. Since there are no employees to pay, e-commerce stores pass the savings on to you. Furthermore, if you are lucky enough to get your hands on a coupon code, you can save more money.

Often physical locations offer a price match guarantee. On the downside, you have to prove that another store is offering the exact model that the store is selling. This is not always as simple as it seems. After comparing the specs, you may be surprised to learn that the units are not the same model.

Warranty

The manufacturer’s warranty will be the same whether you purchase online or at a store. However, many big-box retailers will offer an extended warranty if you pay extra. Garage space heater warranties are standard across the board, and paying extra for an extended warranty may not be worth the additional cost.

Delivery

Depending on the size or dollar amount you spend on the heater, many online shops offer free delivery. Still, you can bring the appliance home immediately if it is available at a physical location.

Returns

Let’s face it, returns can be a nightmare no matter if you buy online or a retailer. Either way, you will have to leave the house to return the item. If you purchase online you have to take the heater to the post office to return. Still, some e-tailers offer free shipping on returns, if the item is sent back within 30 days. If you buy from a physical store, you may have to wait in a long line before you can return the item.

Verdict

Garage Heater UseThe only reason you should bother purchasing a heater at a brick-and-mortar store is if you need the appliance immediately. You can’t test the product in the store to see how it works, so it is better to buy it online. Research shows that when you shop at a physical location, your senses heighten. You see things you have never noticed before, become distracted and purchase things you may not need. Often, you will walk away from the store having spent more money than intended.

When you shop online, it’s easier to remain focused and only purchase the item you need. There are no crowds and no waiting in line. Most importantly, temptations are few. Occasionally, online shops recommend products that you may need to go with the heater. For instance, if you are considering purchasing a portable unit, you may see recommendations for brackets, if none come with the heater. On the other hand, you may be offered a larger unit with more watts or BTUs. This is when online reviews really come in handy.

Once you narrow down your choices, you can read reviews from owners of the product to make sure the item functions as the manufacturer describes. Then, you can and have it delivered straight to your door at a price far lower than you would pay in the store.

Advice and Tips

Heating needs will vary depending on the garage’s insulation. You will need more power to heat a poorly insulated garage as opposed to a structure that has some protection from the cold. Here are some tips for selecting a heater based on different situations.

Fully Insulated Garage

If you have insulation on all walls and tight seals around the windows and doors, a small, portable unit should warm the space comfortably. Choose electric instead of gas. There is no need to add a costly ventilation system if the garage is properly insulated. Just make sure you measure the space. You don’t want to purchase a unit too large for the garages. Otherwise, you will become uncomfortably hot.

Partially Insulated Garage

Garages connected to the house usually share one or more walls. Therefore, they don’t lose as much heat as a detached structure. However, it is possible that the room attached to the garage will be cooler than other areas of the house. In such cases, you may benefit from using your home’s natural gas line. In fact, installation is easy because there is no need to install an additional ventilation system.

You will still need to evaluate the areas that do not share a wall to ensure the unit has the heating capacity to warm the space.

Non-insulated Garage

Advise For Best garage heater No insulation means you need a heater with a capacity that can not only warm the space but can also handle the cold air that can leak into the garage. Not only do you need to make up from losses that may seep through windows and doors, but also any cracks in the floor. Also, check for gaps around light switches and outlets. In most cases, an infrared heater may suffice. These units offer above-average heating. On the downside, you have to stay close to the heater to feel the warmth.

Whether you use your garage for projects, or to store a vehicle, you want it to be bearable when you enter. To maintain a comfortable garage in frigid temperatures, you need to think about the factors that may contribute to heat loss. A space heater designed for the home will not provide sufficient power to heat a cold garage. Continue reading to find out how to keep your garage safely heated.

Heating Efficiency

An insulated garage is rare. Consequently, air is loss through walls, ceilings, windows, and doors. So, keep this in mind when choosing a garage heater.

  • Try adding paneling, foam, or some other form of insulation to walls to reduce heat loss.
  • Add weather stripping around windows to keep them airtight.
  • Check the automatic door to make sure it meets the floor and make sure there is a tight seal around the entry door.
  • Consider installing halogen lighting in your garage. A 100-watt bulb produces 96.5 watts of heat.
  • Naturally, it takes more heat to raise the temperature in a three-car garage as opposed to a one-car structure. Still, it may be unnecessary to heat the entire garage. In such cases, consider a radiant heater to place in your workspace.
  • Most garages have a ceiling height of at least 8 feet. Since heat rises to the highest point of an area, you will need more power to heat the space.
  • Best garage heater produces more power than house space heaters and require 220-240 volts of electricity. Therefore, you will need to confirm your garage is wired to deliver such power and the proper outlets are installed.

Safety

The ideal location to install a fixed garage heater is 7 feet above the floor. Additionally, there should be a 3-foot safety zone. Keep flammable materials and liquids away from the heater to reduce potential hazards.

  • If you choose a gas heater, make sure the garage is properly ventilated.
  • Don’t leave the heater unattended. When you leave the garage, turn the unit off and make sure it is unplugged from the socket.
  • Place the heating appliance on a hard, stable surface to minimize tip-over risk.
  • Supervise children and pets to prevent accidental injury.
  • Unplug the unit before cleaning.
  • Do not block vents. Doing so could lead to a malfunction or a fire.
  • Do not run a cord under a rug and keep it away from high-traffic areas.
  • Inspect the cord regularly for frays.
  • Install a smoke alarm and a carbon monoxide detector inside the garage.
  • If you use a gas unit without vents, leave a window or door open to allow air to circulate. Turn the heater off immediately if you smell gas. If you experience nausea, dizziness or headaches after being near a gas heater, get fresh air straightaway.
  • To prevent electric shock, keep best garage heater away from water and wet environments.

Operating

After a period of inactivity, best garage heater can produce a burning smell. Often, the heater is burning off dust.

  • If the heater has sat idle for a while, wipe it down before turning it on. You should also clean the unit every couple of weeks when in use.
  • While heaters warm the air, they can make the room feel dry. To avoid this, you can add a humidifier to hold the water vapor in the air.

Positioning

Where you place the garage heater is just as important as the type of heater you choose. Some fixed heaters may require the hands of two people for mounting. You should place the heater along a joist or stud. Ideally, the heater will swivel to give you a full range of motion. For optimal efficiency, consider these positions.

Mounted Fan-Forced Heaters: Place these units in the coldest corner of the garage, directed toward the center. Also, mounting them high keeps them out of the path of kids and pets.

Infrared and Radiant Heaters: Mount these units at least 7’ above the floor and make sure any combustible materials are kept at least 3’ from the bottom of the heater.

Portable Heaters: Position these heaters on the floor where they can’t be knocked over and make sure there are no combustible items nearby.

The History of Space Heaters

History of Best garage heaterBefore the development of central heating, people only heated occupied space. Openings in caves, teepees, and huts provided a pathway to expel the smoke. As living quarters became more sophisticated, people had to find new ways to keep warm.

The first space heater was the fireplace. A chimney provided a route for the smoke to escape. Wood in the fireplace provided warmth, but you had to be near the source for it to be effective. In the 1600s Louis Savot of France solved this problem by designing a raised grate that allowed air to flow underneath the wood. As the cold air moved beneath grate, it warmed the air and circulated it back into the room.

The next space heater was a freestanding cast iron stove. Ben Franklin designed the appliance in the 1700s after studying the process of radiant and convection heat. The iron held onto the heat and continued to radiate after the flame died. With a vent at the top of the chamber, the heated air flowed into the room.

Other developments followed and during the latter part of the 19th century, people could choose the type of heat they wanted to run their space heaters. In 1856, German chemist, Robert Bunsen created a device known as the Bunsen burner. The device created an open flame and produced hot, soot-free heat. This development led to gas, propane and oil-fired heaters. When a continuous flame mixes with fuel, it produces a hotter temperature. Many universities still use the Bunsen burner today to perform science experiments.

The first modern day space heater was called a heat blower. It required the user to turn the machine by hand. As the operator turned the appliance, a fan blew air over steam or a heated surface to produce a blast of hot air. With Thomas Edison’s discovery of electricity in 1879, engineers explored ways to use an electric fan to boost heat circulation. By the 1890s, the systems were designed with sophisticated heating elements.

In 1905, Albert Marsh discovered chrome. The substance is composed of one part chromium and four parts nickel. It proved to be 300 times more resilient than other heating elements. Fifteen years later, Lawrence Soule introduced a lightweight heat exchanger made from copper coil. The component works with a fan to transfer heat energy from steam or liquid into the air.

The saying, “everything old is new again,” took on a new meaning during the energy crisis of the 1970s. During that time, many households used zone heaters instead of central heating in an effort to cut cost. The convenience of garage space heaters has given people a new appreciation for using the space for more than storage and parking cars.

Today, old forms of heating combined with new technology make it possible for you to enjoy warmth in the winter while working, entertaining or relaxing in the garage.

Installing a Garage Heater

Different types of heaters require specific installation methods. With most portable electric units, you only need to plug them into a wall. Fixed units mount to the ceiling or wall. Ultimately, you will need to consider the style of the unit and its power source. You should always follow the manufacturer’s instructions and hire a professional for complicated wiring and piping. Still, there are some steps you can take yourself to reduce costs. Therefore, we describe the process of installing electric and gas best garage heater.

Electric Heaters

Best garage heater InstallationThere are two types of electric heaters corded and hardwired. Corded best garage heater is easy to install and operate. For these units, you simply need to find space that is free of clutter without blocking other objects. If it is a freestanding model, just plug it into the wall. You may also have the option of mounting the unit. In this case, you will have to drill holes for the mounting brackets and make sure they are secure before placing the unit on the supports. You still need to clear space to ensure the garage heater operates safely and efficiently. When installing the heater make sure it is pointed toward the area that suffers the most heat loss.

Hardwired models mount to the ceiling or wall with brackets also. You will need to remove the screw from the front panel to gain access to the wiring. Additionally, you must run a sheathed cable from the circuit breaker to a thermostat and back to the heater. Then, the wires have to be coded by a technician to meet safety requirements and local ordinances.

Make sure that the location you choose is solid so it can support the weight of the unit. It should also be mounted in a low traffic area and at high on a wall or ceiling. It is important to note that the first time you run the unit the heater may burn residue and produce a hint of smoke. This is normal and the smoke will disappear after a few minutes of operation.

Natural Gas Heaters

Install Natural Gas HeaterSince these heaters need fuel to operate, you should use extreme caution when installing the units. Before mounting the unit, consider placement and check for clearance, leaving sufficient space for gas, electrical, and venting connections. For safety, the recommended spot is 3’ below the ceiling. Mark the area for mounting before drilling holes for the brackets.

Some units require hardwiring by a trained professional and others just plug into an outlet. Again, angle the heater towards space with maximum heat loss. You will then need to connect the unit to the natural gas line of the home. Next, you have to install a vent to let fumes escape outside of the structure. Consult the instruction manual to ensure safety and efficiency. The instructions will outline where to cut the hole, how to run the wire and the size vent ducts needed for proper ventilation. Usually, you will connect the garage heater’s exhaust to a 90-degree elbow and attach the other end to the opening in the wall or ceiling.

Additionally, you will need to add a vent cap to the exterior of the garage and seal the hole. Once you checked the connections and tested the flame, you should enjoy efficient, reliable heating.
