Heater Types and How They Work

Convection Heaters

Convection heaters warm air by heating an internal element; warmer air rises, cooler air falls, creating a circulation loop (natural or fan-assisted).

Best for: Even, whole-room heating with minimal noise
Typical uses: Offices, site trailers, workshops, utility rooms
Pros: Quiet, consistent heat; low maintenance; available as portable electric heaters or gas-fired convection models
Notes: Look for CSA-certified convection heaters for code compliance

Direct-Fired Heaters

Direct-fired industrial heaters burn fuel (propane or natural gas) and push hot combustion air directly into space without a heat exchanger.

Best for: Open or well-ventilated areas; drying and thawing
Typical uses: Construction zones, barns, outdoor or semi-enclosed areas
Pros: Very high efficiency and fast warm-up; lower upfront cost
Caution: Not for enclosed spaces; produces combustion byproducts—ensure adequate ventilation

Forced Air Heaters

Forced air heaters use a burner or electric element plus a blower to move heated air through ducts or directly into the space.

Best for: Whole-building or large-area coverage
Typical uses: Warehouses, fabrication shops, hangars
Pros: Thermostat control; integrates with filtration/humidification; fast and uniform heating
Options: Gas, diesel, or electric heaters; portable or fixed installations

Indirect-Fired Heaters

Indirect-fired heaters burn fuel in a sealed combustion chamber and transfer heat to clean air via a heat exchanger. Exhaust vents outside.

Best for: Enclosed, occupied, or low-ventilation spaces
Typical uses: Event tents, restoration, food processing, occupied work areas
Pros: 100% clean, dry, fume-free air; safer for indoor use
Trade-off: Slightly lower efficiency vs. direct-fired, but safer for air quality

Radiant Heaters

Radiant heaters (infrared) heat people and objects directly, without first heating the air.

Best for: Drafty spaces and outdoor zones with spot or zone heating
Typical uses: Loading docks, open bays, construction thawing, patios
Pros: Instant, targeted heat; energy-efficient for zone applications
Types: Infrared panels, tube heaters, ceramic radiant

Unit Heaters (Electric Unit Heaters and Gas/Oil)

Ceiling- or wall-mounted industrial heating units that deliver high-capacity heat while saving floor space.

Best for: Garages, warehouses, maintenance bays, agricultural buildings
Pros: Keeps floor clear; broad coverage; available as electric unit heaters or fuel-fired
Tip: Choose models rated for your environment (e.g., washdown, hazardous locations)

How to Size an Industrial Heater

Right-size your industrial heating unit to maintain productivity and safety.

1) Measure space

Area (sq. ft.) = length × width
Volume (cu. ft.) = length × width × ceiling height

2) Estimate required BTUs

Rule of thumb for insulated Canadian facilities: 30–60 BTU per sq. ft.
Poorly insulated or open sites in harsh climates: 60–100+ BTU per sq. ft.
Example: 4,000 sq. ft. × 60 BTU/sq. ft. ≈ 240,000 BTU/hr

3) Factor conditions

Insulation quality, air changes/ventilation, door cycles, desired temperature rise, regional climate

4) Choose fuel and form factor

Electric heaters for clean, no-emission indoor heat where power is available
High BTU propane heaters (Canada-ready) or diesel/NG for remote worksites or rapid warm-up
Indirect-fired heaters for enclosed/occupied spaces; direct-fired for ventilated drying/thawing

How to Size a Heater for a Warehouse or Shop

Basic formula (insulated): BTU/hr ≈ Area (sq. ft.) × 30–60
Cold, leaky, or high-traffic spaces: Use 60–100 BTU/sq. ft.
Example: 10,000 sq. ft. × 50 BTU = 500,000 BTU/hr target
Consider ceiling height and air turns. High ceilings may need destratification fans.

How big a heater do I need for a 40 × 60 shop (2,400 sq. ft.)?

Light insulation: 2,400 × 50–60 BTU ≈ 120,000–144,000 BTU/hr

FAQs

What are industrial heaters?

Industrial heaters are high-capacity heating systems designed to warm large or demanding environments, such as warehouses, construction sites, agricultural buildings, and utility spaces. They include industrial space heaters like indirect-fired heaters, direct-fired units, radiant heaters, and electric unit heaters.

What is the most efficient industrial heater?

“Efficiency” depends on the application:

Direct-fired heaters: Highest fuel-to-heat efficiency for ventilated areas and drying
Indirect-fired heaters: Most efficient choice when you need clean, fume-free indoor air
Radiant heaters: Highly efficient for zone heating or drafty spaces
Electric heaters: Efficient point-of-use with no on-site emissions where power is available

What are the three types of heaters?

Common categories for industrial heating:

Convection/forced air heaters (direct or indirect-fired)
Radiant heaters (infrared)
Electric heaters (portable electric heaters, electric unit heaters)

How to size a heater for a warehouse?

Start with BTU/hr = Area (sq. ft.) × 30–60 (insulated) or × 60–100 (poorly insulated/harsh climates)
Adjust for ceiling height, door cycles, air changes, and desired temperature rise
Contact Cleanflow for a quick sizing consult

Are industrial heaters safe?

Yes, when properly selected and installed. Use CSA-certified convection heaters and other CSA-approved models. Follow ventilation requirements for direct-fired heaters. For enclosed or occupied spaces, choose indirect-fired heaters that vent exhaust outside. Always follow clearance-to-combustibles and manufacturer guidelines.

Which type of heater is most effective?

For enclosed, occupied spaces: Indirect-fired heaters (clean air)
For rapid warm-up in open/vented spaces: Direct-fired heaters
For drafty areas and spot heating: Radiant heaters
For fixed installations with available power: Electric unit heaters

Which heater takes less electricity?

Non-electric fuel-fired heaters (propane, natural gas, diesel) use minimal electricity, typically only for fans/controls, or none at all for some convection models. If power use must be near zero, consider propane convection units like the HS200CVX that require no electricity.

How big a heater do I need for a 40 × 60 shop?

2,400 sq. ft. × 50–60 BTU/sq. ft. = 120,000–144,000 BTU/hr (typical insulated)
If poorly insulated or frequently opened to the cold: plan 168,000–216,000 BTU/hr
