Abstract
The climate of Iceland is such that only hardy vegetable can be grown in the summer. Common crops are potatoes, carrots, cabbage and cauliflower. Soil heating using geothermal water has been practiced in Iceland for several years. Growing on naturally warm land has proven to be very attractive and several new systems have recently come in to operation. The practice is to heat the soil with low temperature geothermal water that flows in plastic pipes buried at 50-80 cm depth and spaced 120-200 cm apart. An engineering study was undertaken to quantify the main parameters that govern heat transfer form parallel pipes in soil. Measurements from operations geothermal soil heating systems were compared to model calculations. Design guidelines have been prepared.
