Dimensions and placement
Both occupy a similar floor rectangle. The Gracia’s published exterior is 39 inches wide by 36 deep by 75 high, with a 35 by 32 by 68-inch interior. Barcelona documentation is commonly around 39–40 by 36 by 73 inches. Preserve installation clearance beyond those numbers.
Heating and controls
The documented Gracia uses seven low-EMF carbon panels; the Barcelona uses six. Panel count alone does not prove faster heating. Compare placement around the back, sides, legs, and floor, plus total wattage in the current manuals.
How to choose
Choose the listing whose exact ASIN and model suffix match the documentation you reviewed. Favor the Gracia if its extra documented panel and interior measurements matter; favor the Barcelona if its slightly lower height solves a real clearance constraint.
Sources and documentation
Specifications, claims, and installation requirements can change. Confirm the current manufacturer manual for the exact model and variant.
