The heat capacity of cast iron is 20% higher than that of stone, and the thermal conductivity is 30 times higher. As a result, the cast iron stones heat the entire heater several times faster and the entire sauna accordingly. Cast iron stones do not crack or crumble due to sudden changes in temperature.

Why is it not recommended to use only cast iron to fill the entire space of the heater? Cast iron steam is very dry and hot. In order to balance the humidity and obtain a pleasant, soft, healthy steam, a mixe of cast iron cores and regular stones are used.
