Open vented, radiators but no hot water!!!!

[hippo69]

Hi I have a potterton house warmer55 back boiler I have radiators but no hot water? I was recommended to put the hotwater on only, and as High as possible this seems to work, but only very slightly?

is there anything else that I can do to possibly shift this air block which I got after draining the system???

please help and many thanks in advance....

Have you checked the level in the F&E cistern?

When you vented the upstairs radiators do get water out?

Could be valve, limescale, knackered cylinder, sludge, thermostat, wiring. Need a bit more info on what happpens

Boiling it up is your next step but that involves taking fire off to get at boiler stat , so prob need to get someone in.

Try and keep fault all under one heading and don`t open new topic it does help us.
