Hot water from combi boiler

[THL4KEL]

My tap water tds is 69 but when I draw hot water from my tap via the house combi boiler the reading is 150. Is that normal? The boiler is only a couple of years old, I had it put in.

From what I understand hot water picks up more dirt from pipes, thus is generally considered more dirty than cold water from the same system.

It was a brand new system installed, but I've had the engineers out a number of times to fix the boiler. Has a seven year guarantee. Just been thinking is something disintegrating inside it.. Also I was using it for pure for really dirty jobs lined up first thing, that was until I noticed the high tds reading. Cheers mate must be dirt built up.

If you get cold pure water with a reading of 000 heat it in a sauce pan then take a reading it will now show a high reading , let it cool back to normal temperatures and it will read 000 again , someone did explain it to me something to do with the mouocoles moving fast when hot or something like that !!!

I wonder if that higher reading it gives impacts the resin more when it runs through the DI with hot water?

Dont think you are supposed to put hot water through the resin I believe it reduces its life ,
