just a quick one guys regarding the above does the thermal store require a PRV on cold main,it came with 1 litre expansion vessel and blender,then two days later a PRV arrives is this needed? incoming pressure is 4 bar but the domestic passes through the coil.its just cause PRV has safety valve on it which i would need to discharge to the outside which would be very difficut to do cause of where the cylinder is situated. cheers.
