Heaters used in industrial settings and garages are built to withstand more wear. They are more powerful than their residential counterparts. Since they are typically installed in spaces that have inadequate insulation and do not have centralised heating. They are subject to severe weather conditions and significant temperature drops. Many use their garages as workspaces, studios, or even a place to hang out. This is one reason why portable garage heaters are so popular. Garage heaters can deliver intense heat in a focused manner to the area where you are currently working. If you’re looking for an Industrial heater for warehouse or workshop, review the following and make an informed decision.

Industrial heaters have many applications.

Large event spaces and warehouses often use industrial heaters to maintain a comfortable temperature. Paint, concrete, and even minor water damage can be quickly dried with the help of an industrial heater that also functions as a dryer. Because the additional heat increases the evaporation rate, using industrial heaters for water damage restoration and new construction drying can increase drying efficiency. This is because industrial heaters are designed to handle higher temperatures. Industrial heaters can also be utilised to heat greenhouses and various other agricultural applications.

Many distinct heaters are designed for use in industrial settings and garages. Our industrial and garage heaters collection includes models installed on the ground, on the wall, on tables, or even on the ceiling. Before making a purchase, you should carefully consider how safe the heater is, how convenient it is, and how efficient it is.

Different kinds of heaters for garages and factories

There are four primary varieties of garage and industrial heaters. Each one is an effective method for maintaining a comfortable temperature in spaces that experience a wide range of temperature swings:


The infrared wavelength technology provides targeted warmth to your working area, comparable to that of radiant heaters. They are known for their silent operation because they do not use a fan; however, they cannot distribute warm air throughout your space as a fan-forced electric heater can. Both infrared and radiant heaters are excellent choices for heating confined areas or spaces where the heat can be focused on a specific area.


Gas heaters are widely used for various industrial applications. Gas or diesel heaters are frequently used in industrial settings, even though they are not advised in garages or other enclosed areas. Although these powerful heaters may take a little bit longer to get to the desired temperature, they can heat your space quickly and efficiently as other heaters. It also includes the restoration of water damage, the drying of new construction, and the warming of large job sites that do not have heating.

Electric portable heaters are popular in various settings, including garages, due to their ease of installation and operation. These devices convert the electrical energy into heat, distributed throughout the area using a fan. Before buying one, it is essential to ensure that it satisfies the power requirements because it must be connected to an electrical outlet. However, more significant (industrial) heaters require 220-240 volts, and many models come pre-wired with the standard 110-120 volt plugs.


Radiant heaters can quickly and precisely heat specific areas of a room or space. They function similarly to the sun’s rays in that they radiate warmth from the unit to whoever is in their path. Because you must be close to the heater, these heaters do not warm an entire garage like electric heaters. In addition to this, they heat up considerably faster than the majority of other kinds of heaters. People who want to heat specific areas like a workstation are the perfect candidates for these heaters because they function similarly to radiant heaters.

Expressing power in terms of watts

The amount of power provided by industrial heaters is measured in watts and/or British Thermal Units (BTUs). Your model’s capacity to heat a larger area is proportional to the number of watts and BTUs it provides. Since there isn’t a primary heat source in garages and industrial spaces, it’s a good idea to invest in a heater with a little more power than recommended. In addition, they are exposed to icy weather due to a general lack of insulation in their homes.

Consider using a radiant or infrared industrial heater if the space you need to heat is small or you want to provide spot heating in your garage. Large garages typically use heaters with an output of between 4,000 and 5,000 watts. In contrast, large event venues and industrial construction sites benefit more from using gas-fueled industrial heaters. Regarding heating smaller workshops, another option to consider is fan-forced heaters with an output of approximately 1500 watts.



When considering the size and power of a heater, some environmental factors to take into consideration are as follows:

Temperature Rise:

Suppose you live in an area of the country that gets unusually cold. In that case, you will need a heater that has a higher BTU rating to keep the same-sized room at a comfortable temperature. The difference between the temperature you want inside and the actual temperature outside is what we mean when we talk about temperature rise. Try to find a heater that can raise the temperature to the desired level without overheating the room.

Comparing Space That Is and Is Not Insulated:

Suppose a garage or industrial space is insulated. This means that the walls and ceiling are insulated, with a garage door and quality windows. If your space isn’t well insulated, you should purchase a slightly more powerful unit to meet the increased heat demand.

Garages for One or Two Vehicles:

Do you have a one-car or a two-car garage that needs heating? To adequately heat an entire garage or an industrial space, you will require a more powerful heater. If, on the other hand, you are only heating a particular area of your garage. You should consider getting a radiant heater because it provides heat to a specific location.

Height of the Ceiling:

Ceiling heights in garages and industrial spaces are typically at least 8 feet. When you have higher ceilings, your space has a larger cubic area, so you will need more BTUs of power to heat the space.

Plugged in versus wired in

Most people are familiar with workshop heaters that simply require an outlet. Still, some models can be hardwired into your wall or ceiling. To hardwire your heater, you will need access to a primary power supply. Cables will be necessary to connect your heater and the circuit directly. All the wirings need to comply with national and local electrical codes. Mounts and instructions for the heater’s hardwiring help make the installation process as efficient as possible.

Hardwired models are far more permanent and take significantly longer than plug-in models. This is why plug-in models are recommended for people who do not intend to use the heater regularly. Hardwiring, on the other hand, provides a secure installation and frees up valuable space on your desk or floor.

Electrical requirements for a storage facility or workshop

Many garage and industrial heaters do not use the standard 110-120 volt outlets because they require a higher voltage of 220-240 volts. This is because garage and industrial heaters are typically more potent than residential heaters. Heaters with 120 volts can be easily plugged into most residential outlets. In contrast, heaters with 240 volts can heat larger areas but are incompatible with most residential plugs. To our good fortune, many garages and industrial spaces have wiring to accommodate more powerful appliances. Before making a purchase, check to see if the wiring in your garage or other space allows for the voltage power required by your heater.

Heater average and other features

Before purchasing an electric heater, you should first determine the total amperage rating of the electrical sockets in your home. You should also verify that your property meets the voltage and amperage requirements of the heater. The majority of heaters require either 15 or 20 amps.

Many people are turning to Dyna-Glo heaters due to their heating capabilities, portability and settings. Kerosene and gasoline are the types of fuel that are used in other types of industrial heaters. These heaters are typically best suited for use in well-ventilated areas such as construction sites. The fact that these highly effective models don’t need any power supply contributes to their widespread adoption. Carry them to your workspace, and turn them on to immediately feel the heat.

Concerns Relating to Safety

There are several other precautions to consider when shopping for a heater for a garage or an industrial space.

  1. Thanks to the Tip-Over Switch, the unit will be turned off immediately if it is accidentally tipped over.
  2. Overheat Protection: To prevent the heater from overheating, an overheat protection switch will turn it off once it reaches the predetermined temperature.
  3. Housing That Remains Cool to the Touch While Others Heat Your Space Some heaters have exterior housing that remains cool to the touch while others heat your space.
  4. Clearances: When it comes to walls, ceilings, and combustibles, manufacturers will provide clearance recommendations. Before you instal a heater in the garage, make sure to get their measurements first.
  5. Electrical Requirements: The circuit that supplies power to the heater needs to have the capacity to deliver the required amount of both amperage and voltage.
  6. Don’t Obstruct Vents: Ensure that your heater’s vents, exhaust, and other openings are not obstructed.
  7. Turn Off: Before attempting to clean, move, or perform maintenance on your heater, you should always turn it off and unplug it first.

Essential Features

Most garage heaters include a manual knob for adjusting the amount of heat coming into your space and a thermostat that controls the heat output by the heater. The temperature settings for low and high heat are found on most thermostats. They prevent your space from overheating while reducing the amount of work involved in its operation. Other heaters continue to operate continuously until they are manually turned off. Thermostats turn off the heating element once the desired temperature is reached, making them an efficient heating option.

Keep an eye out for additional convenience features such as:

  1. Adjustable Louvers, you should aim them directly at your workspace if you want to heat it quickly.
  2. Long Power Cord: Because warehouses, factories, and even some garages can be large, having a long power cord makes it easier to move around in those environments.
  3. Carrying Handle: Move your heater around large spaces or place it wherever you want with an easy-to-use carrying handle that is included with your heater.
  4. Wheels allow you to quickly move your heater and are typically found on larger commercial and industrial heaters.

Option That Can Be Mounted

Heaters explicitly designed for use in garages are among the most adaptable and resilient models currently available on the market. Most of these models can be placed on the ground or hung from the wall or ceiling to save space, contributing to their widespread popularity. You can economise on floor space and shorten the time it takes for the heat to get to you by mounting multiple models on the wall or ceiling.

Consider the Following

You are not recommended to purchase a propane heater in your garage. Propane heaters can pose a significant risk to the safety of those nearby because of many combustible substances. Such as kerosene, paint, and wood, which are stored in garages. We recommend using the other kinds of heaters discussed earlier. Electric heaters are the most common choice for these areas.
