The new heavy-duty SunStar RCH Series spot heaters from SunStar Heating Products do not use electricity and can comfortably heat an enclosed area of up to 2,500 square feet without using fans or moving parts common with many other spot heaters. The heaters are CSA design certified and rated at 95,000 Btu per hour for propane models or 100,000 Btu per hour for natural gas models. Both models are available in manual or thermostatic control. A flame failure safety device is provided for safety. In operation, a stainless-steel heat exchanger beams radiant heat around the entire circumference of the heater for a continuous flow of heat.
