Geothermal is not hot, sometimes it is hot in water, sometimes it is hot in water, and sometimes it is cold up and down. The difference from another building is 10 degrees. I hope professionals can help me solve it. It is urgent. This must be a circulation problem. I think the water supply should be blocked, and it is normal for the backwater to be warmer. The main purpose of heating water for a period of time is to release warm water from backwater. Ask professional pipeline maintenance personnel to check the water supply pipeline. Many new buildings have this problem in heating. Don't worry.
