Turkey is one of the rare countries that have different climatic zones. In addition to the frigid regions, there are also regions with a temperate climate. This diversity also limits the use of a uniform method in conditioning applications. While conventional electric heaters are often sufficient for heating applications in the provinces located in the south, natural gas is used extensively in other regions. On the other hand, ground-source heat pumps have started to be used as alternative conditioning systems worldwide. However, the initial setup costs of these systems limit their use considerably. However, the problems experienced in energy supply in recent years, especially in the natural gas supply in the European region, have reached severe dimensions. In this context, in this study, ground source heat pumps and natural gas systems were compared, and techno-economic analyzes were carried out in heating applications. With the results obtained, the optimum amount of incentives to be provided by the state to ensure the widespread use of these systems has been determined. Although it is foreseen that approximately 65% incentives are required according to the current situation, this rate drops to 36.8% when the natural gas unit price increases in the European region are taken into account.
