Dear Friends,
To start with , I would like to wish you all a very Happy New year and hope that it will be your dream year to begin .
I have recently worked on a floor standing Condensing boiler which is installed for a year . It works well apparently . for the start , I controlled the chemical water which circulates through the boiler . The PH is 8.5 and TDS 225 ppm . As I have read many of your stories here about chemical quality of water in Hydronic systems , this question came to my mind that what are the proper of PH . TH , and TDS or other chemical elements of water in condensing boiler which have less harm on the boiler ?
As always , thanks for sharing your thoughts and experiences which are valuable a lot to me .
Happy 2022 to you all ,
Sincerely,
Roohollah,

The manual for your boiler will likely have the specs you're looking for. Search online if you don't have the printed manual that came with the boiler.

Thank you for the posts . Unfortunately, the previous service company took them put and there is not on the site . Also, I communicated with the company which assembles the boiler screwed me up . Thus , I would like to ask you guys that the ideal range of important chemical elements of water in condensing boiler.
Thanks a gazillion for your support,
Stay safe,

In the absence of specific suggestions from the manufacturer, the most important spec. is chlorides and chlorine, as @TonyS mentioned (the two are different). pH is less important, so long as it is somewhere between about 6.5 or 7 and say 10 or so.Br. Jamie, osb

Jamie...I Agree on the Chlorides and Chlorine
IMO 6.5 is way to low ...
But then again O2 level are also a factor that needs to be considered
You could have a low PH with very low O2 levels and you system >>could<< be Okay.
With all the different materials that are present in modern Hydronic heating systems we like to be somewhere between 8.2 and 10...
Personally we hit a "homerun" when the system is balanced between 8.2 and 8.4
To double back on the Chlorides... If a professional Heating contractor is doing the proper thing he is either using at least 20% Glycol in conjunction with Deionized water..
OR
He is using "High Purity" water(Deionized Water)
In both cases no Chlorides or other harmful minerals should be present.1 -
Right . That was very kind of you all . Thank you . The standard number which you introduced will help me too.
stay safe,

A kit like this is a hood investment. I added the link so you can see the description of what is included. It is a global company, you should be able to source this kit
Happy new year
