Soapstone looks fascinating, but it also stores large inner values. Soapstone keeps the heat long after the fire has gone out. Soapstone releases the heat very slowly and consistent to the room. After only 2-3 fillings the slightly larger soapstone stoves keep the room heated for up to 14 hours, so you do not get up cold in the morning.
Soapstone is a 3 billion years old mineral available in different hardness and colours. HETA’s soapstone is grey, but due to the fantastic play of colours not two stones are identical.
