Abstract

  A new pipe heating system which uses only groundwater stored in a large underground tank was developed in the present study. This paper outlines its design and construction, and provides fundamental data on the developed system. Specifically, it reports on snow-thawing effects and ice prevention, and presents thermal properties based on long-term measurement over 3 years. In addition, the paper presents a possible heating method; circulate water in the tank to the pipes when the road temperature is higher than the water temperature. According to the test results, this method could increase the water temperature even by running the water for short periods of time in winter.
