The system is oil fired, Central heating works fine, it's an open system with a header tank.
Not used the hot water all summer maybe longer with economy 7 and immersion.
When turning hot water on, the motorised valve works fine and water does circulate to the hot water tank but is very
noisy with air?
Will this eventually be pushed to the pump and around the radiators and sort itself, maybe in the highest point
the towel rail?
There is no auto bleed anywhere and no bleed on the immersion loop.
The system is 10 years old but serviced with additive etc.
Any advice would be appreciated.
Thanks
 
On further investigation.
The hot water tank has inlet and outlet for the boiler.
One has the vent to header tank
the other has the output/ input to header tank. With stopcock.
Does that help. I think air is in the coil.
Thus making the noise.
Any suggestions please?
