Hoping that an expert will be able to tell me what the correct setting should be for my central heating auto by-pass diff valve should be. I am experiencing some kettling/whistleing noise from the valve and connecting pipes when the heating comes on and switches off. I have already had the valve changed about 10 months ago, so i do not think it is a faulty valve.
the only helpful info i can provide is;
Boiler Worcester Bosch 37cdi greenstar combination
Flow rate 15 litres per minute. Not sure if this means 54 cubic metres per hour
numbered settings on valve are - open 0.1 closed 0.5 bar. Or have i got these the wrong way round, i.e. open is 0.5 and closed is 0.1.
I know that the valve must be open to get the flow going round the heating system, but not sure which is open or closed. my gut instinct tells me turning the knob clockwise is closing the valve and turning it anticlockwise is opening it up.
I would just like someone to tell me if i am right and what should the correct bar number setting should be. I have got it set on the manufactures setting of 0.2 at the moment
