Who is responsible for the leakage of floor heating pipes?

Heating is guaranteed for two periods, waterproof for 5 years and pipeline for 2 years. During the warranty period, the developer is not responsible. If not handled, you can complain to the local quality supervision department. They are in charge of this matter, and then you can't go to court, otherwise you will be responsible for delaying the warranty period! In addition, if the same place is not repaired twice during the warranty period, you can find someone to repair it yourself, and the cost will be borne by the developer.
