Why is the heating on the first floor not hot? We need to check these places.

1, the radiator vibrates. Check whether the radiator pendant is loose. If the pendant is not loose, check whether there is a seismic source on the system that causes the radiator to vibrate.

2. The main part of the heater is not hot locally, mainly concentrated in the installation mode of entering and leaving from below, because there is gas inside the radiator that cannot be exhausted.

3. The solution is to open the exhaust valve to exhaust the gas in the radiator. Or check whether the system pressure difference is too small or the flow rate is too low.

4. The heating system is not hot as a whole, and the installation mode of entry and exit is downward. When installing the radiator, check whether the diverter valve is installed upside down.

5. For the installation mode of upper inlet and lower outlet, check whether the flow valve is not opened when installing the radiator. There is still something wrong with the system.

6. The radiator has the sound of water, mainly concentrated in the installation mode of up and down, because there is gas inside the radiator that cannot be discharged.

7. The solution is to close the radiator water supply valve, open the exhaust valve to exhaust the gas in the radiator, close the exhaust valve and open the water supply valve. If it cannot be ruled out, check whether the flow rate of the system is too low or whether the air content of circulating water in the system is too large.
