central heating inhibiters

[someonelse]

I'll be moving a radiator and so draining down the system.

When I refill it, should I add an inhibiter?

If so, Sentinel X100, or Fernix F1, or something else?

Or does it make no difference?

Either will be fine. I've no preference, but you should replace lost inhibitors.

As Pete said either of those are fine, when you fit the new radiator pour the inhibitor into the radiator before you open the valves back up and it will circulate into the system once the radiator is in use

?? How do you pour it into the rad? Via bleed valve at top? Surely not?

I was going to pour it into the attic expansion tank.

Or you can inject it in with bleed valve removed
