h all ,
i have a faily old s plan fully pumped system with a worster bosch r 18 heat only boiler,
the boiler was replaced about 4 years ago had a potterton neta heat before. 16/18 i think,
what i want to know it has a gate valve coming from the cylinder back to the reurn to the boiler , what should be the bet setting for this fully open as per the lasted regs or about half way as it is at the moment,
which setting will heat the hot water fasted fully open or half way , one thing i noticed on the the old bullet proof neteheat the boiler would run at full steam but on the newer boiler on hot water it modulates down is this due to return thermister sensor .im talking when only hot water is called for thanks baz
