Basics of Geothermal District Heating

Abstract

Geothermal water is used since ancient times for many purposes, including space heating. It is quite simple to make the hot water from natural springs flow in channels, trenches or pipes (made of stone or wood in early times) and use it for bathing and space heating. A district heating system is a system which provides space heating and (or cooling, as well as hot tap water, to a relatively large number of users located in the same area or district. To build a district heating system which uses geothermal water and which operates properly for a long time in almost any atmospheric conditions in a specific area requires now the full co-operation of a team of specialists in different fields of activity.
