I am looking at a Telford unvented cylinder it has "Aquastat pocket " and "Secondary Return " - are these for the secondary pump to make sure you always have hot water near the taps? I am nit sure but I thought you only need one return for that circuit?
Got it now! One is a thermostat port and the other is the secondary return.
