I have experience in buying and operating various convectors (from budget Rolsen to expensive French ones). This model (series) of convectors turned out to be the most poor-quality and unsuccessful of all that I have seen. My advice - do not get fooled by all sorts of fashionable things like "additional infrared heating" - it all pales in comparison with the workmanship and uneven heating, a buggy thermostat. Once again I repeat the feeling from the model - it warms itself.
