De scaling

[Pacman]

If lets say a heat exchanger was seperate from a boiler lets say a Thorn appollo 15/30 gas boiler and you were about to descale just the exchanger on its own,

what would you use?
how would you use it?
whats the exchanger made from?

Thanks

 

[kevplumb]

lets say hydrocloric acid

lets say VERY CAREFULLY

copper

 

[Pacman]

Would the acid be ok with the copper?

 

[kevplumb]

WHAAAATTTT????? You trying to induce chloride attacks on the stainless steel or summat?

If it's on the DHW side, citric acid will work fine. If its on the primary side, phosphoric acid will work. I did it with Kamco's FX2, no problems.

I wouldn't have thought Cl would do a lot in the time it's in there. ?

I can't use Kamco without a clear flow, can I?

The seals or compound on the joints to the exchanger are red and look very thin, obviously not PTFE, what product is this?

Would it be worth removing the exchanger on its own or try to de scale the whole system? it seems the exchanger is so scaled it kettles the water inside, causing awful noises yet the boiler burns well and pumps fine

Lets say as in lets imagine didn't mean its actually sitting in front of me right now, just trying to get some useful advice which is damn hard from some.

Asking a straight question without all the flowery bits might have got a straight answer.

How do I know? I know nothing about gas boilers, damn dangerous if you ask me.

Just use Sentinel X200 and X100 together and leave them in.
