Decorative and generously warm the Larkspur Rapid Induction Patio Heater produces more heat than a traditional patio heater. The dual infared radiating screens in addition to the enlarged glass cylinder allows for bigger more impressive flame and function. A second air inlet gives greater efficiency to both the heat and flame. The powder coated steel base hides a 20lb propane tank that fuels this 46,000 BTU unit.
