Maybe you could give me a step-by-step of the process you use? You may not find it in the smaller DIY stores but any good plumbers merchants should have it and be able to confirm that you have the right product. I am surprised that the fresh water side of the system secondary heat exchanger cleaning bit need descaling.

A secondary heat exchanger can extract even more heat from the combustion gases before sending it out the secondary heat exchanger cleaning bit pipe.

I would definitely drain the old coolant off first and refill using the descalant pre-dissolved in the water warmed, or even hot, preferably. Many thanks to all for your help.
