A gentle simple thermal water — colorless and transparent, weakly alkaline and hypotonic, and hot enough at the source to be classed as a high-temperature spring. With little chemical bite, the posted analysis documents it for neuralgia, muscle pain, frozen shoulder and cold sensitivity, as well as convalescence and fatigue recovery. The bathhouse notice adds that roughly 300 litres per minute of source water is kept overflowing through a swirl-and-convection system, so there is no temperature gap between the surface and the bottom of the bath, and that the same water heats the floors throughout the building.
