höyrykoreja

Höyrykoreja, a Finnish term often translated as "steam cores" or "steam bobbins," refers to a specific type of heating element primarily used in older Finnish saunas. These elements are characterized by their construction, which typically involves a metal casing housing a series of coiled heating wires. The unique design was intended to allow for efficient heat transfer to the sauna stones above, generating steam when water was ladled onto them.

The design of höyrykoreja was an integral part of the traditional Finnish sauna experience. Unlike modern electric sauna heaters that often use finned elements or ceramic rods, the höyrykoreja's coiled structure created a larger surface area for heat radiation. This allowed for a gentler, more pervasive heat that many sauna enthusiasts found to be characteristic of older sauna designs.

Over time, höyrykoreja have largely been replaced by more modern and efficient electric sauna heaters. These newer models often offer better temperature control, faster heating times, and improved safety features. However, some traditional saunas may still retain their original höyrykoreja, and enthusiasts sometimes seek out these older elements for their authentic sauna experience. Their maintenance can be more involved, and finding replacement parts can be challenging. The use of höyrykoreja is now considered a niche aspect of sauna history and practice.
