What Type of Water to Put in Your Hydronics System

Weezbo

devise that i would likely consider some other fluids than water .

not exactly certain of this however , to me it would depend upon the colour of laser .


there is something about the relationship to the length of the spectrum in angstroms to the medium in which it is used within the type of environment that one is sending information . in other words, i say it would Depend.

blue laser is particularly better to use under water for example.

maybe if you describe the experiment that you want to preform and in what medium and from what location ,it might help get a grasp on what specific means of cooling and the degree of attenuation required...

if you are concerned with a receptor plate or the lens of the laser i think that there are means to control unwanted heat with some very minute electrical absorption arrays...

you can look at the lens of the deep space orbital telescope....the lens of the super microscope, the LHC , the CERN project, National Oceanic Scientific laser experiments,...Fermi Lab,... KAK....

maybe some physicists here will have a clearer formula for you to help with your project.

like i said though , water is not the only fluid worthy of consideration of removing heat...depends upon the environment...and there are lots of variables to consider...




the fluid that we use in residential boilers does not operate in parameters beyond the control of known ,specific techniques. experiments within peoples homes is not what we are into for the most part.

This may be controversial

Okay, I have read over and over how it is really bad to use distilled water or RO water in a hydronics system while de-ionized water is okay. I could not figure out what the real difference is between the two so I set out to do some research.

I haven't reached a conclusion yet, but a lot of things I read seem to lead to the conclusion that DI water is every bit as corrosive as distilled. RO may be better simply because it doesn't do as good of a job at removing impurities.

Consider the following post by Dale Woika that I found at this website:

http://www.ece.rutgers.edu/~maparker/classes/467-Chapters/Class04/drink no DI.htm

Also, consider this thread by a bunch of engineers talking about how DI water is corrosive.

Here's another one:

My question to you guys is how did you decide that DI is better than RO or distilled? I am curious to know because what I am learning about it seems to point the opposite direction.

I have no idea what you said in your post

In the first link, they were talking about the corrosive properties of the different waters in general, which should be applicable to any situation.

The other threads are talking about using water for various things (heating, cooling, etc.) in industrial processes. But again, much of their discussion focuses on the corrosiveness of the different types of water.

So far, I can't see any reason why DI water would be any better than distilled water. In fact, they both seem to be equally as bad.

It seems that the best solution is to use high quality tap water (I think one of those threads lists the content of high quality tap water). Corrosion inhibitors could be added to the tap water, but as long as the hydronics system is completely closed these may not be necessary.

De-Ionized water


Years ago I was involved with a project at an ice skating rink. They needed to make DI water for the ice. When it freezes, it is almost perfectly clear because it is almost pure H2O. It "eats" just about anything it comes into contact with.

Municiple water is usually fine but I have seen instances where well water is unusable. Worst ever was a well that had enough CO2 disolved in it, the owner could have bottled it and sold it as soda water.

Keeping an eye on the Ph of the system water is a good idea.

H20

comes in so many flavors, who knew?

I have done work with DI and RO process systems and the pipe material of choice is 316L stainless steel for mains with polyethylene or propylene (I forget one, the other or both) for the terminal connections. Those were handled by the process folks to cool magnets in proton beam applications.

Yes, the DI stuff is corrosive. I would probably default to distilled only because it would be essentially mineral-free and low in free oxygen.

In the big picture though, when filling a small system, tap water if potable quality, I cannot see that being much of an issue in a closed system. Once heated over the critical temperatures and air is released, what few minerals are dissolved would come out of solution, be drained away and life goes on.

Hmmm....

"The opposite direction"

"For the most part"

"may not be necessary"

" in the long run"

"Good Idea!"

"Life goes on"

Consider...

... if your local water has a history of eating tanks, etc.... send a sample to Rhomar Water Systems. They're a class outfit and they know a lot about water, how to treat it, etc. I used their cleaner and passivating treatments both here in my own home as well as as a project I was involved with in Maine.

The Maine water was much more contaminated than my local supply and the boiler there had suffered through a lot of makeup water over the years. The result of the Rhomar treatment was a lot of black water coming back from manifolds and the radiant circuits in the home. Made a believer out of Mr. Brewer who installed the Vitodens there!

So, I would make that $15 investment with Rhomar before sticking anything into the heating system that might damage it in the long run.

One of the reasons I love Weezbo....
