Indicative Sizing

Selection should be made according to the building's thermal load. As a guideline, 12 kW can cover approximately:

• Well-insulated buildings (30–40 W/m²): 300–400 m²
• Medium insulation (50–60 W/m²): 200–240 m²
• Poor insulation (80–100 W/m²): 120–150 m²

Indicative values; always confirm by calculating thermal loads according to climate, emitters, and insulation level.
