What is this photo indicating

• The paint is coming off the radiator

• The radiator is getting too hot

• Poor circulation due to a build up of iron-oxides

• Poor circulation due to a build up air

Whats wrong in this photo

• The valve is positioned on the wrong pipe

• The valve has not been fitted in the correct orientation

• Nothing its a well install radiator and valve

• I would need to check the manufactures instructions to be able to answer this question

• The valve should be fitted on the lower connections
