Hi, I am Weaver, new to this interesting forum.I have a Vokera Hydra 26.
When originally installed on a new system, no problem with hot or cold water running from taps.
I then needed to extend the domestic water to another shower room.
Drained the system and carried out the work.
Turned the water main back on, got cold water ok, but no water running from the hot side.
Connected the cold mains to possibly purge air, water ran from hot side, but did not continue.
Is it possible the boiler is not allowing the 'hot' water to flow?
I have tried reverse flow etc.
I would appreciate some help, so please if you can, reply to this forum.
Kindest regards
