Five rooms of a 122.4 m² flat, each with its panels and a demo reading. “Feels like” is the average of the air and the surfaces around you: with walls cooler than the air in summer, or warmer in winter, a room feels calmer than its thermostat says.
9.4 m²1 panel, at the end of the hallway, facing the door
You come in from a cold stairwell and the hallway is already warm to stand in. No blast of hot air at the door, just walls that aren’t cold.
Demo reading, 8 pm in January, 3°C outside
43.5 m²4 panels on three walls
Two panels flank the TV, one faces the sofa and one sits by the table. The warmth reaches your back and feet evenly, and nothing blows across the room.
Behind the TV wall, pipes come down inside the wall from the ceiling and join each panel with a single fitting. None of it shows.

23.9 m²2 panels on the wall facing the bed
Two white panels face the bed from the far wall. The room holds its warmth through the night, with no warm air blowing across the pillow.

11.8 m²1 panel, opposite the bookcase
One panel is enough for a room this size. Hands and feet stay warm at the desk without a heater humming under it.

9.5 m²1 panel, opposite the vanity
In winter the bathroom is kept a little warmer than the rest of the flat, so stepping out of the shower is comfortable.

122.4 m²12 panels in seven rooms
No vents, no ducts, and no fan or compressor indoors. The heat pump that warms or cools the water sits outside.
The rooms you just walked through have none of the usual hardware on show.
No grilles in the ceiling or over the doors. Air isn’t blown at you, so there is nothing to aim, close or talk over.
No bulkheads or lowered ceilings to hide them in. The hallway keeps its full 2.8 m ceiling.
Water pipes come down inside the wall from the ceiling and join each panel with a single fitting. They never show on the wall.
Indoors there is no fan and no compressor: the heat pump that warms or cools the water sits outside. No condensation water appears indoors.
List your rooms and their floor areas. The count uses a simple demo rule, one panel for every 12 m², rounded up; it is the same rule that placed the panels in the flat above. A real layout starts with a survey of your home.
12 panels for 122.4 m² in 7 rooms
Demo figures: about 420 W of cooling and 510 W of heating per 600 × 1800 × 90 mm panel.
The showroom is a furnished flat with GLN panels running. Come on a hot afternoon or a cold evening and stand in the rooms yourself.
