It is estimated that infrared heating imply a potential of 15–20% reduction in the net heat demand. The indoor climate, temperature distribution on the crop tables, is more uniform with conventional greenhouse heating. This is also clearly seen in the early development of the roots and the plants. However, these differences are leveled out later in the plant development. Some species even showed a higher quality when grown in the infrared heated greenhouse. A careful design of the infrared heating system and layout of the greenhouses will reduce the differences, especially at the table edges. Radiant heating is suitable for greenhouses and has a potential of reduced energy use.
