Just think of the UFH as installing a new rad,coupled to either a TRV or coupled to a separate stat.

You're over complicating a very simple addition to your existing system.

In terms of your existing boilers capacity,and whether it will cope,check the KW/BTU output of your boiler.
Find a calculator online that will work out the extra capacity of the UFH,and do a comparison against the extra load of the UFH on the Combi.

Never argue with an idiot on the internet. He will drag you down to his level and beat you with experience.
