radiator is about 16 ft2 (5 m2IURPWKHÁRRU

3C Radiator Mounting Angle

The mounting system for Listen LA-140 radiators allow you to mount the radiator in 15 degree increments. The best angle depends on the shape of the room and the orientation of the radiator to the seats within the room. In general, mounting angles of 15 and 30 degrees provide the best coverage.
