Yorkshire water came out to check the pressure, they said that there is 5 bar of pressure at the outside tap which is fed off the stop cock in the kitchen. There is a flow rate of 18l/m at the outside tap apparently but I think he was being optimistic as the kitchen tap which is closer he was saying got 15l/m.
He then measured the shower for me and said it was 8l/m which is completely against what my bucket test showed and my bucket has measurements along the way! The bath taps were showing 15l/m apparently.
Anyway ive been reading up about removing the flow restrictor in the boiler. Apparently my boiler (Glowworm 30cxi) is only capable of 12.3l/m and has a 12l flow restrictor in place. I removed this yesterday as I do believe that these things especially in shower heads there is natural pressure loss through the boiler/shower itself. if I want really hot water for washing up then ill turn the flow of the tap down. The shower is a little more powerful now and the temperature is the same as before, nice and hot.
