Abstract

A device for heating a room (2) in a building by means of underfloor heating, the floor comprising pipe loops (4) for circulation of a hot medium, preferably water. The floor has a subfloor (1) and an upper floor (8) at a mutual distance, so that an air-filled chamber (16) is formed between them. In the outer wall (3) of the room there are inlet openings (7) for fresh air, which by means of negative pressure ventilation in the room (2) flows into the chamber (16), over the pipe loops (4) to heat up, and out through outlet openings (9) in the upper floor (8). The heat absorbed from the pipe loops (4) goes partly up through the upper floor (8), partly out into the room (2) as heated air. The pipe loops (4) extend transversely of the direction of movement of the air from the inlet (7) to the outlet (9) and are partly cast in concrete on the bottom of the chamber (16).
