We started with a line of five soapstone masonry heater models and have grown to over one hundred unique designs incorporating various bench designs, mantels, bake ovens, cook tops and a variety of soapstone color combinations, surface finishes and edge details. Our integrated water coil, heat exchanger allows our customers to warm the areas of their home furthest from the masonry heater and even heat their domestic hot water. Our heaters have been featured in some of America’s most sustainably built, off-the-grid homes. When the US Fish and Wildlife Service needed a sustainable, clean, wood burning radiant heater for the Wildlife Refuge Visitor Center, they turned to Greenstone and our Vitoria 7 masonry heater, featuring Alberene soapstone from Virginia.
In 2010 we introduced a line of refractory heater core kits. These masonry heaters allow for an even greater degree of customization and can be skinned in a wide variety of natural field stone, brick or stucco veneers. These heaters are designed to be installed by your local mason or a skilled DIY’er and deliver the best value available in thermal mass, contra-flow radiant heaters. If you are looking for a green, renewable, carbon neutral heating source, you have come to the right place. Masonry heaters are also known as a Russian fireplace, soapstone stove, heat-retaining fireplace, ceramic stove, tile stove, contra-flow stove, Finnish stove, Swedish stove or kachelofen. Now these are not all the same device but do share the central design feature of thermal mass heat capturing, radiant warmth. For too many years, Americans have allowed the majority of the heat produced by their stoves and fireplaces to escape up the chimney. Today it is our mission to stop the waste and clean the air, and we are proud to have introduced hundreds of families across the United States to a better wood heat.
