Why Calcana
Calcana low-intensity infrared tube heaters warm people and surfaces directly instead of the air, using up to 40% less fuel than forced-air systems. The flame is fully enclosed inside the emitter tube, so there are no open flames, no glowing red parts, and reliable operation in wind, rain, snow, and temperatures down to -40°F.

How Calcana Compares
Infrared heat isn't blown away by wind like forced-air heaters; heats efficiently even in breezy conditions
Only patio heater on the market with a patented variable/modulating burner: one heater covers everything from gentle warmth to snow melting
Marine grade (316) stainless available for coastal/salt-air installs, beyond the standard 304 stainless most competitors offer
Wall control panel included standard: unlike Bromic and Infratech, where advanced controllers are sold separately, every Calcana heater ships with its own dedicated low-voltage On/Off Hi/Lo wall control panel at no extra cost.
