I have an apartmanet in a new building, 2 rooms, 2 years warranty under the contract. The heating is the same in the whole apartment but in one room the temperature is +22, whereas in the other room it’s +18. It is incredibly cold to sleep there at night. The developers have tightened all the windows, we have insulated the floors and, using special equipment, we have revealed that the temperature of one wall is between +10 and +14 degrees. We have sent an official complaint (twice) asking to solve the problem and insulate the wall, but we only received lame excuses that all these claims are unreasonable, and that the temperature of 18 degrees is quite normal. In November, the insurance will expire and it looks like the developers are just dragging on time.
