Combined UFH and radiator system

[Pkitch]

Hi guys, probably a silly question but in my new extension I have water UFH connected to my combi which runs the radiators in the rest of the house.
Although both are controlled separately do they use the same water? What I mean by this is if I put inhibitors in a radiator will it also enter the UFH loop or are they separate closed loops?

Yes

Yes

Great thanks for the quick reply, so I guess when draining or flushing I treat it all as one system as well?

Yes

It's also recommended to use a biocode Inhibitor for underfloor heating systems. So on top of your inhibitor you should be using a bottle of either sentinel x700 or adey mc7.
