The present study examined the possibility of using geothermal energy in the area of Jędrzejów. Determination of the potential of thermal resources in this area was possible due to deep boreholes drilled in previous years. The analysis concerned the assessment of the geological setting, depth of aquifers, water temperature and mineralization, discharge rates of wells, reservoir parameters, and the value of geothermal resources. Promising zones for acquiring geothermal energy are the central (Cenomanian and Upper Jurassic aquifers) and north-eastern parts (Trias- sic aquifer) of the area. Taking into account discharge rates of wells and water temperature, the geothermal resources of the region are promising mainly in the context of their use in recreation and/or balneotherapy. There is a certain possibility of developing the resources for heating purposes, but generally this option would require using of heat pump systems. Based on the calculated value of the energetic potential of the aquifers, the Cenomanian aquifer has been selected as the most interesting. For this aquifer, a simple scheme of geothermal pool installation was proposed.
Celem niniejszego artykułu jest prezentacja dwóch średniowiecznych urządzeń grzewczych znajdujących się w zabytkowych zespołach klasztornych – cystersów w Jędrzejowie i augustianów-eremitów na Kazimierzu w Krakowie. Oba obiekty usytuowane są w obrębie obecnych piwnic klasztornych, które w przeszłości miały charakter suteren o funkcjach gospodarczo-kuchennych. Szczegółowa inwentaryzacja architektoniczna obiektów, datowanie i rekonstrukcja stanowią przyczynek do szerszych studiów nad urządzeniami i systemami grzewczymi na ziemiach polskich w dobie średniowiecza.

The aim of this article is to present two medieval heating devices located in the historic monastic complexes – the Cistercian monastery in Jędrzejow and the Augustinian hermits’ monastery in Kazimierz quarter in Krakow. Both objects are situate within the existing monastery cellars which in the past served as basement with utility-kitchen function. Detailed architectonic inventory of the objects, their dating and reconstruction are a contribution to thorough studies on heating devices and systems used in Poland during the medieval period.
