Since 1967 Sunglo has been manufacturing USA-made residential and commercial-grade outdoor gas patio heaters! Sunglo patio heaters operate quietly, using highly-efficient infrared radiant energy, this heating method is simple to operate and draft-free. There are four basic models of the Sunglo patio heater line to provide as much flexibility in patio design as possible. For uncovered settings, the Sunglo PSA265 is the best choice by providing a permanent post mount with the option of manual, semi-automatic, and fully automatic ignition systems. Furthermore, the Sunglo A242 adds versatility by providing the convenience and economy of a natural gas heater, but with the flexibility of a portable heater. For a complete portable and self-contained appliance, the Sunglo A270 propane heater can be set up almost anywhere. Lastly, for covered settings and commercial application, the Sunglo A244 is a suspended heater that will heat the patio while leaving the floor free of obstruction.
