This study was carried out to develope the local heating system using hot water pad. Results of the study were as follows. When the outside temperature of greenhouse was reached at the lowest of 0.8°C, the surface temperature of heated water pad, the temperature inside tunnel, inside temperature of greenhouses were getting colder sequentially. The average temperature of local heating zone for experimental plot is 25.4°C, and control plot for entire space heating keep the average inside temperature at 25.6°C and internal greenhouse temperature were maintained constantly at the setup temperature in both a test and a control plot. The survey for temperature of inlet and outlet for hot water pad at above case showed that the average inlet temperature of hot pad was 50.2°C and outlet temperature for that is 47.8 °C and the temperature difference between them was 2.4°C. When the Circulation flow rate is 112 L/h and the temperature change is 1°C, the amount of heat exchange was increased by 112 kcal and the flow rate was changed to 360 L/h, the amount of heat exchange was reached at 360 kcal. The analysis of heating costs showed that local heating systme using hot water pad cost 2,976 won /day and the entire space heatingsystem cost 32,987 won/day. Comparing with the entire space heating system, local heating system using hot water pad could save the 91 % of heating costs customarily required.
