Our oil central heating system has eight radiators, but the radiator in the hall only ever heats up slightly.
A plumber suggested to turn off all the radiators except the hall one and when the hall radiator heats up to turn on all the other radiators, but when i turn off the radiators do i need to turn off both the valves on all the radiators?
