How Radiant Heating Works and Why It Is So Effective

 

Radiant heating uses infrared energy to warm people, equipment and surfaces directly rather than heating the air. A radiant heater mounted at ceiling level emits infrared radiation downward. This radiation passes through the air without warming it and is absorbed by floors, work surfaces and people below. These surfaces then re-radiate heat into the surrounding area, creating comfortable warmth at the working level. This is fundamentally different from warm air heating, where warm air rises to the ceiling and the floor stays cold.

​

• No stratification: Radiant heat travels to floor level directly. It does not rise to the ceiling like warm air

• Works with open doors: Warms surfaces not air, so draughts and door openings do not affect it

• Zone heating: Target specific work areas without heating the entire building volume

• Instant heat: Full output within seconds, no warm-up period

• Lower energy use: Heats people and surfaces directly rather than the entire air volume

​

Gas Radiant Heating: Space-Ray

 

Gas radiant heaters use natural gas or LPG to heat a radiant tube or ceramic plaque that emits infrared energy into the space below. They are the most common choice for full-building radiant heating in large warehouses, factories and hangars:

• Space-Ray LR: Gas radiant tube heater for large industrial spaces. Uniform heat distribution across wide areas. 

• Space-Ray AD: High-efficiency gas radiant tube heater with a double skin reflector for improved heat output and performance.

• Space-Ray SRP: High-intensity gas radiant plaque heater. Concentrated infrared heat for spot heating in workshops and production areas

​

Electric Radiant Heating: Tansun

 

Electric radiant heaters require no gas supply, no flue and no combustion, making them simple to install and ideal for buildings without mains gas, zone heating and retrofit projects:

• Apollo: Robust electric radiant quartz heater for industrial spaces. Strong output, high-level mounting, ideal for warehouses and production floors

• Sorrento: High-intensity electric infrared for spot heating at workstations, loading bays and packing lines. Fast warm-up

• Sorrento Ceramic: Same high-intensity output as the Sorrento but with zero visible glare from the heating element

• Linea: Slim, contemporary electric infrared heater for spaces where aesthetics matter. Wall or ceiling mounted for workshops, mezzanines and commercial units

• Panel: Frameless ceiling-mounted radiant panel for offices within industrial buildings and under mezzanine floors. Low glare and discreet

Gas vs Electric: Which Is Right for Your Building?

 

Gas radiant tube heaters like the Space-Ray LR are typically the most cost-effective option for heating entire warehouses, factories and hangars. Electric radiant heaters like the Apollo and Sorrento are ideal for zone heating specific work areas, buildings without mains gas and retrofit projects where no gas pipework or flue is available. Many buildings use a combination of both.

Radiant heating is used across warehouses, factories, workshops, hangars, sports halls, loading bays and garden centres. It is particularly effective in buildings with high ceilings, frequent door openings and draughty conditions. Contact Hadar Industries today for a free site survey and recommendation on the right gas or electric radiant heating for your building.
