Résumé

The article determines monthly heating/cooling capacities and coefficients of performance for both systems. It notes that overseas data concerning the optimum depth for a horizontal water-loop for a ground-source system are not valid for South African conditions due to climatic differences. The authors calculate the payback period, net present value, and internal rate of return of ground source systems for various depths for Pretoria. The conclusion is that ground-source systems are more viable than air-source systems. In addition the optimum depth for a horizontal water loop is very shallow compared to recommendations in the literature.
