The Thermostone® CR line of room heaters by Climastar® contains stone. The heaters deliver heat via three methods: accumulation, convection, and radiation. Heat is absorbed by the heater's stone. The heat is circulated throughout the stone, then rises to warm the air above it. Once the selected temperature is reached using the unit's thermostatic control, the stone continues to radiate heat without any additional electrical consumption. Four models are available: CR500, CR1000, CR1500, and CR2000. The units feature a plug-in electrical connection, a thermostatic control, and a wall-mounting bracket. The heaters are available in two colors: sand beige marble and sienna brown marble.
