A device for an air valve, particularly for use with a fresh air inlet through a wall (7) in living rooms (20), and wherein the device (1) comprises a receiver (9) preferably consisting of metal, plastic or another air-tight material, and wherein the receiver (9) is adapted to be tightly attached to the wall (7) around the internal valve opening (8), and wherein the receiver (9) is divided into an outer room (12') and an inner room (15), a connection (11) being established between the rooms (12', 15). To the receiver (9) is attached a bulb holder (13) having a supply of electrical current for a bulb (3), so that the fresh air stream flows past the bulb (3) and receives heat therefrom before it leaves the receiver (9) and escapes into the living room (20). |
