Has anyone used RO water in a copper boiler and had problems because of the negative ions?

Bonjour Brad,
Excuse this question, what is RO water ?
Personally, I like alternating demineralized water and tap water because the latter is not calcareous at home (and demineralized water is remineralized with the metal of the boiler).

I've been only using distilled water - I keep gallons of it because we have extremely hard water here in central Texas.

I wished I would have gotten the water softener option added to my home when I had it built back in 2000 - worst cost cutting decision I ever made. I am pretty sure the amount of water parts and CLR I have had to buy would have paid for that option 10 times over by now. Though the CLR has come in handy cleaning out these steam engines I been working on.

Using RO water mixed with 5% tap water is good for your boiler, and will reduce scaling very much.

Here is some info on Reverse Osmosis, no copper piping:

As Maxwell says adding 5% untreated water is necessary to protect your boiler.
