Radiant Heating for Professional Greenhouses
Ensure stable and optimal thermal conditions for your greenhouse crops
Professional greenhouses allow off-season cultivation and optimize yields in controlled environments. However, maintaining ideal temperatures in winter or during cool nights can be an energy challenge. Electric radiant heating is a reliable, energy-efficient, and targeted solution, ideal for sensitive crops and production greenhouses.
Why use radiant heating in a professional greenhouse?
Radiant heating warms plants, soil, and equipment by radiation without having to heat all the air volume:
- Reduction of energy loss due to stratification
- No air mixing = less stress for plants
- Less evaporation, better humidity control
- Simple line or island installation, depending on the crop
- Zonal heating = energy savings in unoccupied zones
Crops concerned
- Vegetable greenhouse crops (lettuce, tomatoes, cucumbers, etc.)
- Flowers and ornamental plants
- Nurseries, cuttings, young plant production
- Tropical or cold-sensitive plants
- Soilless culture (aeroponics, hydroponics)
Suitable infrared types
- Long wave (IR-C): gentle heat, ideal for slow growth, germination zone, or root cultivation
- Medium wave (IR-M): for fast-cycle crops or greenhouses with high ceilings
Recommended power (to be adjusted according to insulation, ventilation, and region)
- Tunnel greenhouse 20 to 30 m²: 3,000 to 5,000 W
- Greenhouse 50 to 100 m²: 6,000 to 10,000 W distributed by zone
- Large modular greenhouses: multi-unit system with automated management
Installation tips
- Suspended mounting on cables or steel/aluminum profiles
- Variable height depending on crop (1.8 to 2.5 m above plants)
- IP65 rating recommended for humidity, automatic watering or high-pressure cleaning
- Thermostat, programmer, or soil/temp sensors for automation
Advantages for agricultural production
- Improved germination, more regular growth
- Protection against night thermal shocks
- Reduction of fungal diseases related to condensation
- Localized heating to limit operating costs
