i do not have any pressure at all on my Halsted ace and when i switch it off and on soon afterwards it just boil for few second and then cut down.
Is there anyone with similar experience who can help me with this please ?
Check that the system is full (if not use filling loop or internal tap) DO NOT fill above 1Bar cold. Why did you loose pressure has a rad been removed to decorate or do you have a leak?
