Morning
I was wondering if some one could help me ?
My house has an OSO Super S Unvented Cylinder 300L which is designed to operate at 3.5 Bar.
The mains cold feed to the tank is fitted with a Pressure Reducing Valve. When all the taps in the house are closed the pressure gauge reads 2 Bar. I understand that this is the static pressure reading. This pressure drops when a tap is opened.
I would like to increase the pressure of the water going to the unvented tank.
What I am confused about is whether I set the PRV to have a static pressure of 3.5 Bar or a dynamic pressure ( taps open ) of 3.5 Bar ? I understand that if the dynamic pressure was set at 3.5 Bar then the static pressure may well be higher.
Can any one please advise ? Thanks in advance.
