Hi there,
I installed a solar thermal system to a property in the summer and changed an old vented cylinder over a two coil cylinder (also vented). Has worked fine until last couple of weeks when the customer is complaining of air locks in his hot water taps. My first thoughts are that the temp stat might have gone and the water is getting far too hot (he does say that it's very hot when it comes out) and blowing off causing an air lock in the system.
Any other thoughts on this?
