the heating is small and fits nicely even super under a computer desk. For me it is between the office chair and the wall. There is an outer wall, the arm's length of me away. This region is ice cold and the little heater warms the air there's business. Unfortunately, the heat is no longer sufficient to the legs and feet. Bad is that the power cable under the heater and thus very close to the hot parts comes to rest. In addition, the supply is very short about 120 cm. The cooling time from the hottest state on cold amounts to about 22 min.
