I've been looking a long time for a heater for my covered patio. A gas-powered equipment came for me not in question, and in reading the many comments on the various electrical devices, I came to the conclusion that electric heaters are suitable mainly as a source of heat at the changing table and can be used more as a garden lamp outdoors. The Einhell heater ran my way when I wanted to give up my search already. Was particularly impressed and I am of the infrared technology that allows only objects of all kinds, whether dead or alive, directly heated and the energy is not wasted on the environment or blow away by the evening breeze. The delivery was made by Amazon, as always, very quickly. I guess I'm lucky that I live very close to a major Amazon distribution center, which in turn is located in close proximity to one also no small DHL parcel center. Perhaps there is a direct access. The construction of the heater was smooth and is also Grobmotoriker how loose hinzukriegen me. I read somewhere that makes the device adjusted in height. I'm just wondering how that is, when is the instruction manual that the telescope tube must always be taken off in the heating mode to the full length of min. 1.80 meters. The commissioning of the Einhell also goes easy: plug into the socket, switch pressed and thus set the desired temperature and ready, the heater heats. Incidentally, should children have problems to reach the switch on the heater head in 1.80 meters, so not easy but good. As a further safety feature of the Einhell has a tilting protection and automatic shut-off, but a hurricane should then again sweeping over the terrace and take or knock down the heater. When the hurricane also brings a few drops of water, the heater is on the other hand also prepared. So far so good. The heater is relatively petite, not take up much space, and we must not play with large gas cylinders. Unfortunately, the heat output does not match my (high) expectations. At first I wanted to send the unit back, have me but then changed her mind, if only for lack of acceptable alternatives priced. Meanwhile, Master Einhell and I arranged us because within about two meters of the Heizpils around can also be cooler evenings to spend a little longer on the terrace, and when a maximum of four people will sit around the artificial campfire them with adequate clothing and relative calm obenrum warm after a while even the red wine or alternatively of white wine, beer and all soft drinks in glass. Against the cold feet and the Einhell is powerless. So long story short: I would have liked a little more heat production, but can me so get used to the device. Five star for everything around it, 2 1/2 star for "the unit" makes me deserve three stars.
