Property me the frost guard for a heating oil tank room (about 8 square meters) gained because it is located in an outbuilding at the house. So far I am very pleased with this unit and it has also been described in about 5 off C + by itself, and at 8 degrees C + thanks thermostat. (At its option, you can of course still higher place) With a Funktermometer what I specially concerned had I can now read the temperature in the room comfortably from the couch and does not need in the bitter cold and snow to the door. Let's see how it looks then at -20 degrees !!! ; D
Addendum: :(
!!! The frost guard has not even survived an entire winter season. For continuous operation so completely unsuitable !!!
