Adding inhibitor. How?

[Mr Blobby]

The good news is that the UFH is finally, sort of, up and running and the heat pump is totally awesome.  

 

The bad news is the plumber left the bottle of inhibitor I gave him on the floor.  I don't know what bit of "make sure you add this inhibitor and biocide when you fill the system" was not clear, but maybe I made it sound too complicated.

 

Everything here in Northern Ireland is closed for the annual marching and rioting holiday period.  The plumber is unlikely to return before August.  Obviously the thought of my heat pump rusting away is rather unsettling, but am I being too dramatic?  Its only a couple of weeks right?  Or should the inhibitor be added as a matter of urgency?

 

If it should be added now then how?  Its impossible to get a plumber and I have no plumbing skills at all.  The inhibitor is in a bottle, not the injector thingy, and we have no magnetic filter with a useful dosing thingy.

 

I suppose I could maybe drain a manifold.  Or just leave it.  Whats the worst that can happen?

I would just buy an express version make life easy. Do you have a filling loop? If so you inject directly in to there.  Do biocide and inhibitor from same company and range to ensure no compatibility issues

This was my first choice but Northern Ireland is shut down this week and all the merchants are closed.  Hopefully somewhere will be open tomorrow.

 

Daft question time.  I attach the inhibitor to the filling loop, open the valve and then inject it.  So there is enough pressure (>1.5 bar) in the inhibitor can to inject the inhibitor into the pressurised system?  Or depressurise it?

Leave it pressurised, thats the whole idea of it.  There will be zero issues waiting a week or two if required
