Corrosion inhibitor coming out of hot water taps?

[PRS1]

Unless its a combined feed and vent Tank!

Nowt to do with tank anyway!

Might be a sealed heating system.

Can you take a pic of airing cupboard with Hot water tank?

Draining down cold water tank, bail out remaining water in tank and drain hotwater cylinder / flushing is the way to go to remove inhibitor.

That's probably the best bet I reckon.

Hmm, I have not seen that copper vessel above cylinder before.

I will have to google.

Dan.

He did explain that to me, cant remember the exact terminology but it was something like a fast response hot water vessel, contains 4 or 5 litres so theres instant hot water or something?!

The copper vessel above the cylinder looks like a hydro spartan unit,it uses the domestic vent as a top up for the heating.

 

[chunkymonkey2778]

theres a bleed nipple on top of it, not sure if this helps in any way.

so going on what people have said so far, he's put it in the only tank he could've done, but there shouldn't be any in the system?

thanks very much for all your help so far btw.

The loft tank in your picture is for cold water storage and not an F&E CH one.

okay thankyou, so the inhibitor shouldve been put into a radiator rather than just into the tank?

It should've been put in via a radiator (or other filling point), and not any in the tank whatsoever.

great. so if i turn off the hot water at the programmer and leave the hot taps running will this empty the tank in the loft?

and its cold water storage just for the heating system right? still safe to use the cold water taps as this is off the mains and isnt discoloured?

sorry to ask so many dumb questions but im used to cars not domestic heating.....

If you add it via a radiator or anywhere else it will still get in the domestic water as you have a hydro spartan unit,this makes it similar to having a primatic cylinder.

 

[chunkymonkey2778]

ok.

so i need to drain my cold water tank and flush the system then.

so how do you stop the internals of the system rotting out if you cant put any sort of inhibitor in the system?

Ah, apologies for my duff info re the radiator fill - I've not seen that type of setup before.
