Their angular, fractured surface stores more heat and allows water to evaporate efficiently across a wider area — producing softer, more consistent steam. The irregular shape also allows for loose, open placement in the stone basket, which is essential in electric heaters to ensure heat can move freely between stones and heating elements. Good airflow through the stone space directly extends the lifespan of the heating elements.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eCaution: Light (ceramic), soft (soapstone), and smooth (rounded) stones are not suitable for electric heaters and may cause damage or poor performance.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eEach natural stone is unique in shape and size. We recommend purchasing an additional box to allow selection of the best stones for fit, form, and function.
