We bought this radiator, because we have a difficult space to be heated and for this now and need a booster heater. With an already older radiator we have not managed to get the temperature below 5 ° C outside temperature to over 14 ° C in the room. This radiator made it within 2 hours, the room temperature hochzuheizen to 18 ° C (which in this case was requested temperature) and not even at full heating power only Level 2 half turned. And he has this temperature was maintained well. And the unit also looks appealing. We have the same 2 more devices risen and we are sure that we do not have to be cold this winter.
