- The last flushing of the heat exchangers was less efficient, hence the decision.
- That is why after the disassembly, I want you to install flanges on the pipes.
- Yes, the new ones are acid resistant. We have made such a decision together with the user.
- We will have to weld them.
- But the new ones have flange connections?
- What is the reason of this change?
- Close the shut-off valves on supply and return pipes. Next, open the valve on the bypass. Once you have done it, disassemble the old heat exchangers and install the new ones.
- What is the action plan?
- Yes, I saw your license and it is still valid.
- Good morning. Your task is to replace the old plate heat exchangers for hot water and central heating.
- But the new heat exchangers are different from those which are to be disassembled?
