Hi
I recently drained down my central heating system to replace a faulty radiator valve but when I filled it up I've been left with no hot water!
The hot water inlet to the cylinder is "piping hot" and the return is cold. I can't feel any movement inside those pipes by holding them and was wondering if it could be some kind of airlock inside the coil in the cylinder?
The system is gravity with pumped CH and the CH works fine. Everything was fine before I drained it down and then filled it back up again.
I'd be really grateful for any help or pointers on this!
Thanks!
