Radiant Heating for Garden Greenhouses: Direct Heat for Your Crops and Plantings
Protect your plants from the cold while controlling humidity and energy consumption
Garden greenhouses allow year-round cultivation, but cold winter temperatures can harm sensitive plants’ growth. Electric radiant heating is an efficient, targeted solution that warms surfaces and plant matter directly, without drying the air or causing excessive condensation.
Why choose radiant heating in a greenhouse?
Unlike forced-air or fan heaters, radiant heating works by infrared radiation. It warms plants, soil and structures without relying on ambient air:
- Instant heat from the moment switched on
- No ventilation = less evaporation or plant stress
- Gentle, even temperature across sensitive crops
- Wall-mounted, suspended or under-glass installation
- Reduced power use thanks to targeted heating
Greenhouse types covered
- Amateur garden greenhouses (aluminium, wood or glass)
- Semi‑professional horticultural greenhouses
- Tomato, citrus or tropical plant greenhouses
- Conservatories converted into kitchen gardens or winter gardens
- Outdoor mini-greenhouses or seasonal glazed areas
Which infra‑red type to choose?
- Long-wave (IR‑C): for gentle and constant heat, ideal for plant development
- Medium-wave (IR‑M): best for partially open or very large greenhouses
Recommended power
- Small greenhouse (4–6 m²): 1 200 to 1 800 W
- Medium greenhouse (8–12 m²): 2 000 to 3 000 W
- Large greenhouse (>15 m²): install 2 to 3 modules spread evenly
Installation tips
- Suspended under the roof or wall-mounted
- Recommended height: 1.8 to 2.5 metres
- Aimed at planting benches or walkways
- IP55 rating recommended (resistant to moisture and splashes)
- Thermostat recommended to prevent overnight overheating
