Is this enough inhibiter?

[alan0259]

Hi

I have 17 radiators in my house and a combi boiler

Recently drained down and I’m refilling

Assuming this 1l bottle here is way more than enough for what I need? Guy at the shop had no idea...

Thanks in advance

Since you've gone to all that bother Alan I'd stick another bottle in.....it takes a huge amount to overdose.
Its Fernox F1 for me - easy to inject into a radiator direct which can save a lot of faff.

1 bottle usually does 10 single panel radiators as a rough guide. I suggest you may need a bit more, although that looks like a dodgy brand that may not actually do anything anyway. Buy cheap, buy twice...

Cheap inhibitor is usually a waste of time, but no matter what you use you will need more than 1L, whatever you use dont mix them use bottles of the same
