John Vancak founded Calcana in 1989 with the goal of producing the best patio heaters for commercial and residential use. In fact, various figures from the restaurant industry approached him with the need for efficient and budget–conscious heating. Thus, he developed patent–protected infrared patio heaters.
The Calcana system uses the combustion of natural gas or propane to generate comfortable infrared energy, which heats the objects beneath it, rather than the air. Just as the sun's energy melts ice and snow, so do the heat waves produced by Calcana Infrared Heaters… unimaginable performance!
