Ground Source Heat Pump manifolds

 As we have two ground source loops in 32mm pipe coming into the house, they will have to be joined up, or “manifolded” as a plumber would say into 38mm pipe. Here is the neat manifold that comes in the kit from the heat pump suppliers with shut off taps. There is one manifold for the incoming “warm” water/glycol mix at about 12 degrees C and one for the returning cold water which will typically be around -5 degrees C.
