water color

rod robbins

I have a new system, buderus.311 control, with wirsbo pex.I noticed the water looked dirty after week of use.I flushed the system last week and cant tell yet if it will get dirty again.Can any tell me if the water in these systems stays clear or is it normal for the water to dis-color over time.
Thanks for the help

Quite often You get what you put into it.

let the water back out and put red food colouring in the boiler then the water looks a nice cherry red:)

Did you use

a cleaner or just a fill water flush? The fluid will pick up some color from the oils and fluxes, etc left behind from assembly and installation.

I use a hydronic system cleaner and it does flush out some ugly water. It leaves the water with a tan tint, instead of the greasy black, common with uncleaned systems.

Check the ph of you final "fluids" to assure you have protected the components of your system adequatly. Be sure to use a good quality fill water also. Hard water will coat all the heat transfer surfaces and drive down efficiencies. In worse cases cause noises in the boiler from poor heat transfer.

which \"hydronic system cleaner \"?

What Cleaner?

If it's a new system and is not Aluminum, use TSP and then flush the system with water. Ours is Noburst System Precleaner.

TSP

is one option. Used to be a suggested method in many boiler installation manuals.

These days with aluminum, alloys, stainless, and many other materials in the system, I prefer a cleaner designed for the job.

Many of the chemical companies manufacture hydronic system cleaners. I use a Rhomar product, one of the few aluminum friendly products. In addition to soap (TSP) hydronic system cleaners will have ph buffers, O2 scavangers, film providers, and stronger cleaning power.

You can read about

our cleaner and treatment products on our web site www.rhomarwater.com under hydronic products.

These two products were specifically formulated with all of the modern hydronic componants in mind. The cleaner sets up the system and treatment protects the system for at least a year or more.

I am with Hot rod on this one.

there are rust ,flux,oil small copper shavings ,silver and or lead,maybe some sawdust, sheet roc mud, paint small wood shavings and perhaps some teflon and assorted pipe sealants, and really we havent even begun to consider the water quality. as much as a hassel as it is ....hauling water to sites with a well is my general standard.water at high heat is going to rid you of lots of stuff you wouldnt want in the boiler and system.so ,i'd drain it down and add some food colour to it just to be able to see the fluid. that is one good thing about anti freeze that isnt clear, you can easily see how well your spirovent is working .

hr

Air vents are typically

the first thing that gets slimed in a dirty, oily system. This often leads to improper air removal, which leads to further corrosion, and on and on. A mere speck of solder flux or pipe dope will plug that pin hole air vent discharge.

If NOTHING else, run a flush to get the chunky products out! copper chips casting sand, threading remenents, solder balls, etc.

But if you do that step, might as well add a cleaner at initial fill, run it to temperature, and flush.

Trying flushing this method into a 5 gallon bucket to see what really comes out.
