Deep Geothermal for District Heating and Spa resorts in Romania and Bulgaria

Abstract

Romania and Bulgaria have rich resources of deep Geothermal on a temperature level that is suitable for direct use in District Heating. Existing systems that have been developed until the mid-1990th are up for renovation or even reactivation of the dwells. This paper and presentation will focus on concrete projects realized and in feasibility stage in both countries to show the opportunities and challenges.
Apart from the exploitation of the dwells the energy efficient distribution with sustainable solutions for the district heating network is key for the success of these projects. Piping solutions with over 40 years of lifetime in geothermal water transport are one part of the solution. The other success factor lies in the optimized design and selection of all components as well as in a realization by trained contractors. All that will be presented in two District Heating projects in Romania and Bulgaria.
