My daughter has an old system in her house whereby when you call for hot water, everything works fine.
Just the dhw, radiators stay cold
When you call for heating, you have to have the dhw on, and the heating cuts out on the dhw tank thermostat.
The system appears to be a fully pumped open vented s plan?
Is there a faulty valve?
is there a valve fitted?
There is the supply to the boiler, and the tank stat wiring only at the time clock, which makes me think there is no valve, or not wired?
any thoughts please guys?
