Direct Thermal Flow™ describes FinSteam's multi-path heat transfer concept, in which heat is transferred simultaneously to the sauna stones, surrounding structures, and directly into the sauna air by the hot combustion gas and air stream. This allows the available heat to contribute to warming the sauna immediately from the beginning of operation.
Humidity Balance™ describes the continuous production of water vapor during properly adjusted LPG combustion and its contribution to maintaining the sauna's natural base humidity throughout burner operation. This moisture is generated as an integral part of the combustion process without requiring additional humidity-generating equipment.
Sauna Climate Engineering™ integrates heat transfer, moisture generation, thermal storage, and ventilation into one coordinated thermal management system. The objective is to support stable temperature distribution, comfortable humidity, and consistent sauna conditions throughout heating and normal operation.
