Especially in spring, when it can be very fast cool or cold evening, the heater is fun and provides many pleasant evenings without thick winter jacket. For a smaller balcony I might recommend the "smaller" device with 2,000 watts.
BENEFITS
+ Insane heat output, which is still 6 meters palpable
+ Long line (about 5 feet)
+ Immediately warm without long heating
+ Warm, very pleasant for me infrared light on the skin
+ Radiates in a very large angle
+ Not the air but only bodies and objects are warmed
DISADVANTAGES
- Adjustment of levels in example 800, 1,600 and 2,500 watts missing me
Suitable device in the order only for very large rooms, balconies and terraces -
Overall I am very satisfied with the Semptec heaters and would buy it again. Maybe next time with fewer watts, as much in this case does not help much. But for very large balconies, rooms, tents or terraces I speak from a strong buy recommendation and awarded 5 stars.
