Hi,
I'm a complete novice when it comes to this, so bear with me.
We had uf heating installed 6 years ago, controlled by individual room thermostats. For no reason the system has stopped working.
I've included a few photos of the system and would appreciate any guidance on where to start please. We have a heating engineer coming out in a week but could use it on now!
I wondered if it could be a sticking pump. I've played with the screw and released a few drips but no joy. The pump is a Grundfos Ups2 25-40/60.
As for the rest, I wouldn't know where to start!
All help appreciated. Thanks

When you played with the chrome screw did you remove it to see if the pump spindle was rotating? If not do this withe the system off and use a small screw driver to engage the pump spindle and give it a small amount of twist to break any adhesion, then carefully replace chrome screw and nip up so as not to damage the 'O' ring or thread.There should be some u-tube showing this trick.
