Utilization of Ground Water Directly for Space Heating Application Using Heat Pump- Demonstration and Case Study of Dehradun, India

Abstract

A case study is presented regarding the utilization of ground water directly for space heating using a heat pump. A ground source heat pump was installed in Dehradun, Northern region of India to demonstrate the technical and economic feasibility of the method of utilizing direct water for space heating. The setup utilizes heat potential of the ground water obtained from a wellbore to deliver design heat output of 12 kW to the room. The exit water from the heat pump system is delivered back for normal utilization purposes. Performance analysis of the installed heating system was done in the present work. Result shows technical and economic feasibility of the method to be replicable on a larger scale in areas with existing tube wells which are used for extracting ground water for various other applications.
