Central heating not circulating after New Navien Combi fitted to Santon Premier system.

I agree. The boiler developed a leak from the heat exchanger seal 9 weeks in and charged 200 quid to do a 35
minute job under guarantee. Now they do not want to know.

That would of been a warranty job and the manufacturer liable for payment, not you!
Unfortunately to rectify this is going to cost more and the situation clearly demonstrates the installer doesn't understand the principles.

Time to get a solicitor involved

This customer is prepared to spend money in excess of what was paid for what should have been paid under
warranty in a small claims court.

So where in the system should the extra push pump be located please?

Where the old boiler pump was

I think between us we have arrived at the problem. My concern now though is as I mentioned above are the existing rads at ∆T 60°c, if so the flow temperature will need to be around 90°c to give a rad MWT temperature of 80°c and full out put.

yes hat makes sense but I have to get the water around the system in the first place.

The boiler is capable enough so where do I install a secondary pump?

Yes I agree completely. However I suggest separation, pumps in series is not always going to work.
