Mineral composition

As for the origin of the hot springs of Cieplice, they are infiltration water 16-22 thousand years old.


Cieplice water is:

  1. low-mineralized (mineralization lower than 1000 mg/dm3)

  2. fluoride/silicon (fluoride content 2-12 mg/dm3,the amount of silicon dioxide as metasilicic acid is up to 135 mg/dm3)

  3. thermal (in shallow wells the temperature reaches 370 C, in the deep well 650 C, and at 1500-2000 m below the surface the temperature may reach 870 C. , making it the hottest springs in Poland.

Mineral composition of hot water:

  • Sodium Na  
  • Potassium K  
  • Lithium Li  
  • Calcium Ca2
  • Magnesium Mg2
  • Iron Fe2
  • Fluoride F-
  • Chlorine Cl-
  • Sulfate SO4
  • Bicarbonate HCO3

The Hot water field

of Cieplice is located within the Cieplice Valley, being part of the Jelenia Góra Valley. The presence of hot springs in Cieplice is determined by the tectonics of the area. The hot water field connected with granite rocks should be viewed as a special hydrogeological structure. It is a spatially complicated reservoir of underground waters made by a network of rock fissures. The earth's thermal resources constitute the source of heat for those waters.

Currently water is being exploited from three shallow and one deep well:

  1. Source No 1 "Marysieńka" – 0,5 m3/h

  2. Source No 2 "Sobieski" – 0,04 m3/h

  3. Source No 4 "Nowe" – 1,00 m3/h

  4. odwiert "Cieplice-2" (depth 661 m) – 10,00 m3/h

The well called "Cieplice-1" (depth 2002.5m), with possible 45 m3/h, is not being developed or used. On the basis of that hot spring well, it is planned to build a complex of thermal swimming pools and baths or to use the geothermal properties as a source of energy.
