One shot in main heat exchanger

[gileros]

Can I ask if anyone has used one shot to clean main heat exchanger

That's Sulphuric Acid, you'll have no heat exchanger left if you pour that in.

Is it ally or stainless?

 

[gileros]

It was stainless gastec, I've done the job now and it worked a treat, Been told not to use it on ally tho. An Ariston engineer told me when I was on a product training day that he always carries some in his van. Was working on a Heatline Vizo that made a loud groaning noise that you could hear around the whole house and turned out to been the main heat exchanger was partially blocked

I believe 'spirit of salts' or brick cleaner are good alternatives .
