| Reason | Specific performance |
|---|---|
| clogged pipes | The water flow in the terminal radiator is not smooth and the heat cannot be transferred. |
| Insufficient system pressure | The overall circulation efficiency of the heating system is low and the terminal heat is insufficient. |
| Gas accumulation in radiator | There is air in the radiator, which blocks hot water circulation. |
| The valve is not fully open | The water inlet or return valve of the end radiator is not fully opened. |
| Unreasonable design | Heating system design flaws lead to uneven heat distribution at the end |

| Solution | Operation steps |
|---|---|
| Exhaust treatment | Open the radiator exhaust valve to exhaust the internal air |
| Check valve | Make sure the water inlet and return valves are fully open |
| Clean pipes | Contact a professional to clean your heating pipes and remove blockages |
| Adjust system pressure | Check heating system pressure and add pressure if necessary |
| Redesign the system | If the design is unreasonable, it is recommended to re-plan the heating system. |
