Read on to learn about the most effective types of industrial electric heaters available in Canada, their applications, and key considerations for facility managers and engineers.
What Are Industrial Electric Heaters?
Industrial electric heaters are robust heating systems designed to warm large commercial and industrial spaces efficiently. Unlike residential heaters, these units are built to withstand demanding conditions while providing consistent heat output for warehouses, workshops, manufacturing facilities, and outdoor work sites.
These heating systems convert electrical energy into thermal energy through three primary heat transfer methods:
Conduction Heating
Direct heat transfer through physical contact. Industrial conduction heaters include immersion heaters that heat liquids in tanks and cartridge heaters for warming metal components.
Convection Heating
Warms air that circulates throughout the space. These systems heat the surrounding air, which rises and creates natural circulation patterns for even temperature distribution.
Radiant Heating
Emits infrared radiation that directly heats objects and people. Radiant systems are highly efficient for spot heating and work well in areas with high ceilings or outdoor applications.
Main Types of Industrial Electric Heaters in Canada
Forced Air Heaters
Forced air heaters use internal fans to distribute heated air quickly across large areas. These versatile units work well in warehouses, workshops, and construction sites where rapid heating is essential.
Key Features:
- High-velocity airflow for quick heat distribution
- Available in portable and stationary models
- Suitable for temporary and permanent installations
- Effective for spaces up to several thousand square feet
The King Electric KB ECO2S series exemplifies advanced forced air technology with smart ECO2S features that automatically adjust wattage based on heating demand, significantly reducing energy costs.
Convection Heaters
Convection heaters rely on natural air circulation rather than fans, making them ideal for quieter environments. These systems heat air gradually, creating consistent temperature zones without the noise associated with forced air models.
Applications:
- Enclosed industrial spaces require quiet operation
- Areas where air circulation must be controlled
- Environments sensitive to dust or debris movement
- Long-term heating solutions in manufacturing facilities
Radiant Heaters
Radiant electric heaters emit infrared energy that directly warms objects and people rather than heating the surrounding air. This makes them extremely efficient for spot heating and high-ceiling applications.
Advantages:
- Instant heat delivery to targeted areas
- No heat loss through air circulation
- Effective in outdoor or semi-outdoor environments
- Energy-efficient for specific zone heating
Radiant heaters excel in loading docks, outdoor workstations, and facilities where workers need warmth in specific locations, rather than whole-area heating.
Unit Heaters
Electric unit heaters combine heating elements with fans in compact, wall or ceiling-mounted packages. These versatile systems work well for both primary and supplemental heating in industrial settings.
Benefits:
- Space-saving wall or ceiling installation
- Even heat distribution throughout the coverage area
- Available in various wattage options
- Easy integration with existing HVAC systems
Models like the King Electric Yellow Jacket portable shop heater offer powerful 3750W heating with built-in thermostats and durable construction for demanding industrial environments.
Immersion Heaters
Immersion heaters heat liquids directly by submerging heating elements into tanks, vessels, or containers. These systems achieve 100% energy efficiency since all electrical power converts directly to heat in the liquid.
Types:
- Flanged Immersion Heaters: Mounted through tank walls with bolted flanges
- Screw Plug Heaters: Threaded directly into tank openings
- Over-the-Side Heaters: Suspended from tank tops into the liquid
Industrial applications include heating process fluids, preventing freeze damage in storage tanks, and maintaining optimal temperatures for chemical processes.
Portable Electric Heaters
Portable industrial electric heaters provide flexible heating solutions for temporary applications, equipment maintenance, and emergency situations. These units typically feature wheels, handles, and rugged construction for job site mobility.
The King Electric portable utility ceramic heater offers dual power settings (750W/1500W) with efficient ceramic heating elements and built-in safety features, making it ideal for smaller industrial applications.
Duct Heaters
Duct heaters are installed directly into HVAC systems to provide supplemental heating for large buildings. These units integrate seamlessly with existing ventilation systems to deliver consistent temperatures throughout industrial facilities.
Features:
- Integration with building automation systems
- Even heat distribution through existing ductwork
- Energy-efficient operation with precise temperature control
- Suitable for large-scale industrial heating applications
