The boundary integral equation method (BIEM) was developed in this study to analyze the performance of steady state potential type problems. The numerical implementation of BIEM was done for earth tube heat exchangers as an example. A general performance correlation equation for system variables such as: tube diameter, soil temperature, and ambient air temperature was developed. The location of tubes below the ground level significantly affected the heat exchanger thermal performance. The earth tube exchangers for heating greenhouses during winter months can be economical.
