The second small tube of geothermal water released hot water last night, and it was cold when touched this morning.

First, there is air in the geothermal pipeline, which hinders the water circulation. Generally, the water separator will have an exhaust valve, and the newly used and installed geothermal water must be drained. The method is as follows: For example, if your home is a five-way water separator, first close four roads (only one road can be opened), open the backwater exhaust valve, and drain one of them until only water comes out, and so on. Second, if the indoor temperature is low, it will reach 65433. The water supply temperature of floor heating must reach above 45℃ (the radiator needs a water temperature of 60℃, so the geothermal heat is not hot, and the radiator is even less hot). You can find a professional (or yourself) to measure the temperature of the water inlet pipe. If you can't meet the standard, you can contact the property in your respective community. Third, the circulation of the system is poor, the water pressure difference of the heating company is small, and the water flow rate drops, resulting in geothermal heat not being hot. This should also be solved by the property.
