IMPORTANT!! GB142 AND WATER QUALITY

J.C.A._3

I got the fax on Wed. afternoon. The directions got 3 holed and put into the manual on thurday morning, and everyone was told it was there.

For all of you guys using Capco, they will be stocking Rhomar products if not already...soon.(next week?) Chris

New installation supplemental

Attention all buderus GB 142 installers, please make sure to check the PH level of the water you are using in your GB 142's it must be between a 7 and an 8.5. Secondly, NEVER use salt bed exchangers (water softners) to fill the boiler or for make up water. Lastly, the ONLY two glycol manufacturers buderus is allowing for their heat exchangers are NOBLE 'Noburst Al' and Rhomar 'Rhogard'

Thanks Ray:

I have not had the pleasure of installing Buderus yet, but I just wanted to add that PH levels are always important no matter what manufacturer you go with. Even if you think the water is suspect, it is always a great idea to at least check. I live in the NE and the Buderus is not really available or at least I haven't seen many wholesalers dealing with it. Weil McLain and Dunkirk dominate the market here, but I am always open to change in search of a better product.:-)

Ithink that goes for ALL aluminum block boilers...

Not just the Buderi GB's....

pump speeds

I thought that was particularly interesting. I'll have to go back and set some primary pumps to low speed.

What Memo?

Does anyone have a link to this memo from Buderus.

Water Quality

For systems that already in that has softened water what are you supposed to do.Up here in Southern Ontario you have some nasty water with calcium,iron and sulfur.Is there a treatment for those conditions?

the lesser of two evils

if the water is extremely hard it will do as much, if not more damage then the softened water. In my opinion. It will coat all the HX surfaces within hours of firing and stay there forever.

Keep in mind when a softener is first installed with new, never backwashed media there is no salt residue.

And actually, if the softener is adjusted and operating properly there should be little of no salt residue left. That's why it is called an ion exchange process. The salt attaches to the hard water deposit and they wash down the drain.

Knowing how well that actually occurs is the question

By far the best answer is to import DI or DM water. I buy mine from Rhomar, which happens to be local.

If you do enough boiler work Culligan, and probably others, will rent these DI tanks and swap them out as they required.

All this is a mute point, however, if you don't use a cleaner first. As you still have solder flux, cutting oil, assembly lubes, pipe dope, and who knows what inside a new system.

Ever read the label mon a jar of solder flux? Ever see how much is left INSIDE the pipe after soldering. Any idea how that reacts with new inhibited glycol?

I'm glad the boiler guys are adding this info, and I thank them but I still think they are missing the more important cleaning step. And the list of acceptable products.

Failed HXer issues will go down considerably when both steps (cleaning and treating)are properly carried out

Thanks Hot Rod

Is there a sodium test that can be done such as test strips.

Thanks

I have a question. I have done a few DI systems for ice skating rinks and that DI water is extremely agressive. We have to use special pipe for the DI side.

Are you really using DI water in your systems??

DI water only if

you add the inhibited treatment, in my case Rhomar 922, with the fill water. DI and RO water can be very aggressive. Which is why it is not handled with copper piping.

The boiler treatment product will buffer the ph back to where it needs to be. As well as adding that most important thin film to prevent attacks for aggressive fluids.

Same goes for blending glycols with DI water. The inhibitor package in the glycol handles the aggressive (pure)water.

Thanks for bringing up that point.
