The boiler house´s original steam boiler and other parts of the central heating system for the Mikvah (ritual baths) have remained intact. Demonstrating a high level of technical proficiency in its time, the heating plant was manufactured by the Poledniak Karoly firm of Kosice, Slovakia, and was most likely installed following a fire in 1909. The heating plant’s main function was to elevate pressure and water temperature to produce steam. Because Jewish law requires that the water in the Mikvah cannot be heated by a direct flame, the water was heated by firewood in a boiler made of steel. The resulting steam was then used for heating the ritual bath water and for the Mikvah’s steam baths (saunas). The boiler house is a cultural monument listed under the number 1789/3 in the Central Register of the Cultural Monuments of the Slovak Republic.
