As per regs at that time, the hallway radiator hasn't got a TRV, the flow through it was turned down by the installers, so that it doesn't heat too quickly, shutting down the entire house.
But the new boiler has a bypass loop, so if all the rads are TRVed and shut off, the pump will keep running with the flow going through the bypass until the hall thermostat shuts it off. But the council refuses to accept that, despite it being in the handbook, so no hallway TRV.
