Drinking (potable) water and combi boiler!

[ericmark]

In the electric section we have this thread https://www.diynot.com/diy/threads/boiling-water.509334/page-4. I have stated in my house the tap in kitchen keeps the hot and cold separate right to the point where it comes out of the spout, originally fitted when we had a header tank so cold water not contaminated by hot water. It now has a main 7 water heater so hot water is no longer stored, but taps never changed.

In mothers house the mixer tap mixes in the base,

as shown in the diagram, so if hot water used last, then we get half a cup of hot water, before the cold comes through, I thought this is OK with a combi as the water store is so small and not open to atmosphere. However we have one guy who says you should not drink water that has been heated by a combi boiler.

So do my mothers taps all need changing, or is water from a combi potable, and if it is potable can anyone direct us to where it says it is potable.

I can't direct you to any thing regarding potable water from a combi - but having drunk water from an old fashioned Direct hot water system, used for making tea- so the electric kettle didn't boil too long - then put in a flask. I can tell you that, although it tasted rank it never killed me, or my old Dad who used to do it. He was Norm F. The F stands for Frugal
