Sentinal X100 concentrate in open vented

[kgreen84]

Around this time every year I put a dose of sentinal in the system normally via the F+E tank in the loft. Access is more then tight and with having to drain down is a pain in the bum to be honest.

Is there anything wrong with using the injected x100 into a bleed valve of a rad rather then the 1 litre stuff on a open vented system? Used the concentrate on my mothers at the start of the year via the filling loop as she has a combi.
