Why carbon panels are common
Large panels can distribute radiant energy over more wall area and fit behind guards. Product pages often emphasize even coverage, but the cabin layout and whether your body blocks one user from another still matter.
Why ceramic emitters remain useful
Ceramic elements can produce concentrated radiant output and may warm quickly. Poor placement can create hot spots, while good placement can target areas missed by broad panels. Judge the complete heater map.
How to compare two models
Sketch the seated body position over the heater diagram. Note back, side, calf, floor, and front coverage. Then compare wattage, controls, service access, electrical requirement, and manufacturer documentation instead of counting panels alone.
Sources and documentation
Specifications, claims, and installation requirements can change. Confirm the current manufacturer manual for the exact model and variant.
