A hotel suite at dusk: a linen sofa, a black marble table with champagne on ice, and lamps glowing behind the bed.

A quiet amenity for exceptional homes.

Radiant heating and cooling by GLN. Water, warmed or cooled outdoors, flows through slim panels, and the room settles at the temperature you choose. No vents, no ducts, no fan.

Comfort you never hear.

A heat pump outside warms or cools water. The water runs through aluminium-fin panels that stand 90 mm from the wall, and the walls, ceiling and furniture come to the temperature you set. Warmth and coolness then reach you by radiation, the way you feel the sun on your face or the cool of a stone hall, rather than on a current of air.

On a July afternoon the air may read 27 °C. With the walls at 22 °C, the room feels close to 24.5 °C.

Felt temperature is roughly the average of air and surface temperature (ASHRAE 55, ISO 7730).

  • No vents, no ductsNothing is cut into the ceiling, and nothing blows across the bed.
  • No fan or compressor in the roomThe heat pump and its compressor stay outdoors.
  • No pipes on the wallsPipes come down inside the wall from the ceiling and meet each panel at a single fitting.

The residences

Six homes, from morning light to midnight. In each, the panels sit quietly in the architecture and the air is left alone.

Photographs are illustrative. They are not GLN projects.

  1. A bedroom with a sculpted wooden headboard that curves up the wall, lit from behind, and a white bed.

    The Suite

    Warm walls behind a sculpted headboard, and no draught across the pillow.

  2. A bedroom with frameless glass walls on two sides, opening onto a terrace, a lake and mountains.

    The Lake Residence

    Radiant panels, no vents. Glass on two sides, and the room stays calm through a July afternoon.

  3. A classical drawing room with painted panelling, a marble statue in the window and the sea beyond.

    The Sea Villa

    Silk curtains that hang still. Nothing is blown through the room.

  5. A dark penthouse at night, a wall of windows full of city lights.

    Cooled through the night, with no fan to hear. Only the city lights move.

  6. A bathroom with a freestanding tub on black marble, a carved screen, and a glass wall over a city at night.

    The Bath

    A warm bathroom in January, and no grille in the ceiling.

Silence

No fan to hear at night and no unit humming on the wall. The heat pump works outdoors; inside, the room simply holds its temperature.

Stillness

Air that isn’t blown at you. Curtains hang straight, papers stay where you left them, and there is no draught on your neck.

Materials and finishes

Each panel is 90 mm deep. Behind the face, extruded aluminium fins carry the warmth or coolness of the water, and a single fitting joins the panel to pipes hidden in the wall.

For architects and developers

GLN is planned alongside the ceiling and wall build-up. Our engineers in Wuhan prepare panel layouts, room-by-room loads and the heat pump selection for Hubei’s hot summers and cold winters, and they coordinate the concealed pipe runs with your contractor.

  • Panel layouts and loads for each room
  • Heat pump selection for hot-summer, cold-winter conditions
  • Pipe routes inside the walls, agreed with your contractor
  • Drawings and finish samples for client presentations
