Within the context of sustainable housing, considerable research attention has been on different devices and techniques to lower energy consumption and alternative, environmental-friendly alternatives to generate energy. Recently, scholars engage increasingly in the economic aspects of these devices and techniques. This study elaborates on the study of Kulcar et al. , which have investigated the economy of exploiting a two-stage heat pump with heat exchanger using low-temperature geothermal sources for building heating purposes. The results of the analysis suggest that under the circumstances defined in , the system is an interesting investment from a financial viewpoint. However, the results turn out to be strongly dependent on the evolution of the electricity and heat prices. It turns out that the net present value of the investment is more sensitive to changes in heat prices than it is to variations in electricity prices.
