Nestor Martin’s cast iron is renowned worldwide for its exceptional quality. Since the beginnings of our first foundry in 1854, our production process has always been at the avant-garde. Moreover, our cast iron is made from 95% recycled materials, in keeping with our commitment to protect the natural environment. The S model is a fresh, modern take on the cast iron stove. Rounded lines gracefully outline the robust castings, which subtly hide the technical advances concealed within. The S model is available in three sizes: the compact S13, the mid-sized S23 and the larger S33.
