Current setup is a OSO 330l unvented cylinder which also supplies four bathrooms. The house is old and big, with the water having to flow that bit higher. There is also a Grundfos Hot Water Circulator Pump attached to the pipe work. The flow rate isn't great so we're looking to see what we can do to improve the situation.
Static pressure is approx 5.5 bar
Flow rate at cold taps is 7.5l/min
Flow rate at hot taps is 3.6/min (this is probably due to the strainer needing a good clean)
With three taps running static pressure falls to 3 bar and the cold flow is negligible from the three taps.
The options as we understand them would be to either boost the incoming supply or add an accumulator. Attached is a picture of the stop cock and piping which we believe is a candidate for an upgrade. However, what we don't know is how much the water board will charge to update the pipe work into the house.
The other option is an accumulator. Would that improve the flow rate we're currently getting, or should we be looking at another solution?
Thanks
