Are things getting a bit nipply where you live? They are here, which means it's now fireplace posting season, and I think the Piet by Fredrik Hylten-Cavallius is an excellent way to start it off.Piet burns ethanol instead of wood. That means it's chimney-free and completely portable. A layer of rock wool fire insulation between its reflective interior and ceramic exterior protects surrounding walls and furniture. Gorgeous!
