Dyna-Glo carries both indoor and outdoor heaters. Models include liquid propane, convection kerosene, radiant kerosene and natural gas heaters. Power levels range from about 10,000 to 300,000 BTUs.
For instance, the Dyna-Glo 30,000-BTU Portable Propane Tank Top Liquid Propane Heater is used only for outdoor heating. It provides warmth for a radius up to 25 feet. The heater's ignition system must be started with a match. The power supply is a 20-pound propane cylinder.
Other models, such as the Dyna-Glo 23,000-BTU Convection Kerosene Heater, are advertised as supplementary indoor heating sources. The 23,000-BTU model has a push-button battery ignition system. A safety switch automatically turns the heater off if it tips.
