Tulikivi’s round Naava heater combines uncompromising design and Finnish soapstone with high technology. Intended for traditional sauna bathing, the Naava is made of beautiful, ribbed soapstone that retains heat effectively and releases it as comfortably humid and evenly soft heat. The heater is designed to serve sauna-goers for many years and to withstand the test of time. It is a modern piece of Finnish bedrock in the sauna. The Naava is especially suitable for small saunas and can be integrated into the benches. The heater can be connected to a KNX building automation system.
