Abstract：In recent years, with the advancement of geothermal heating engineering technology, the projects and scale of geothermal heating have continued to grow. At present, geothermal development and utilization projects are mostly researched on economic evaluation methods, main control factors of benefits and case analysis of project benefits. Post-evaluation of economic benefits can provide strong support for improving existing projects, adjusting projects under construction, and guiding proposed projects, but there are few studies on post-evaluation of economic benefits of completed geothermal heating projects. In order to improve the economic benefits of geothermal heating projects and change extensive management to intensive management, this paper studies the post-evaluation principles, methods and evaluation indicators of the economic benefits of hydrothermal geothermal heating projects, and take the geothermal water heating project of S community in Xianyang City as an example to carry out the post-evaluation research on economic benefits. Through research, it is suggested to carry out post-economic evaluation of geothermal utilization projects that have been completed and run for 3 to 5 years. In order to do a good job in the post-evaluation of economic benefits, the evaluators should continue to track the progress of the project, collect and analyze various historical data in a timely manner, and select a variety of methods for prediction, comparison and mutual correction. In order to fully reflect the benefits of geothermal heating, the indirect benefit evaluation of energy conservation and emission reduction of geothermal heating projects will be strengthened in the future.
