Dan is incorrect in stating that a pump in parellel would not increase the flow presure should the Boiler and Pump both be on at the same time it would however clearly this is a bad idea as any water going though the pump would not get heated
WTF is that first attachment supposed to be regarding circulators in parallel?
Obviously a clueless idiot with regard to the head/flow rate on a parallel set up.
No, as I will have an interlock so when ever the aux pump is off the bypass always opens. So should the boiler pump activate, it can send water around the bypass, it will just have a short 14 meter circuit.

Dan suggested I should connect them in parallel, I thought it was a bad idea for the reasons I stated, i suggested doing things in series. How would you suggest I boost the head pressure of my system? I thought having a pump in series that supports a 18 meter head should do the trick.
It does not need to, either the heating is on the aux pump will be on, and the motorised valve will be closed, or the heating is off, the motorized valve is open and the aux pump may or may not be running. Should the boiler need to shut water in the CH system it still can at all times.
havent read this thread fully so may have been mentioned
if your house is open plan your differentials will be fairly correct at 1-3 degrees per m in heat rise
in other words hot air rises
if your house has doors and you close them on the bottom floors the heat will rise in those rooms far faster than any from heat scavenged from upstairs
