Greenstone was founded in 2008 in Denver, Colorado, to bring the radiant wonders of soapstone masonry heaters to North America. 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 Valencia 7 masonry heater.
