Just because I am now am really worried...What tube is this?

Todd_33

Doh...

CSA Canadian standards association..

b137 ? B137.0-05 Definitions, general requirements, and methods of testing for thermoplastic pressure piping

I can tell what is after the B137, I am guessing that it falls under

B137.8-05 Polybutylene (PB) piping systems for pressure applications

1 Scope

This Standard covers polybutylene (PB) pipe, tubing, and fittings. Nominal pipe sizes (NPS) covered are NPS-1/4 to NPS-2. Fittings covered include insert-type fittings, socket fusion fittings, plastic-to-metal transition fittings, and compression-type fittings. Pipes, tubing, and fittings covered by this Standard are intended for use in pressure applications such as hot and cold potable and nonpotable water distribution systems operating at a pressure of 690 kPa and at a maximum temperature of 82 °C.


So poly butyl tubing.. I am going to assume. So no oxygen barrier.

Derheatmeister said that limits my choice of boilers.

Please look at this pictures to help me determine the type of tubing....I am worried...

Hmmmmm

Any numbers, lettering, brand ID on the tube?

Todd_33

I don't see a thing... nothing zip nada...

Looks like...

regular old nylon tube to me. used a lot for things like the ice maker hookup on your fridge. I don't necessarily see it as a problem as long as it's carrying potable water and has nothing to do with your hydronic heat.

there was....

a brand of polybutylene that was silverish in color.

Todd_33

Puke,

it has been for 14 years...

What do you mean?

Heating system for 14 years?

Todd_33

It has been fine in my hydronic heating system for 14 years now. I have 3 of these manifolds spread throughout the house, in addition to the main manifold in the utility room.

As I contemplate a boiler replacement, I was trying to determine the type/brand of tubing. The only thing we new at purchase time (1998) was to avoid Entran. New questions have been raised about oxygen barrier/non barrier tubing..

Unknown

Right,,,

My guess is you have non barrier which is supposed to cause premature failure / excessive corrosion of iron components, especially the boiler. Can't be sure about the barrier thing unless you have a way to trace it back from whence it came.

Todd_33

I need some patience... Wait for Richard to stop on by and give me a diagnosis/prescription. Non barrier tubing is not the end of the world, just another thing that needs to be worked around..

I have spoken to three different contractors in the past few weeks, and at least 4 different contractors have worked on the system in the last 12 years...

Richard/Derheatmeister is the only who has any answers that make any sense. Heck he is the only to have asked any questions... Seriously.

I am just wound up that I have spent thousands trying to band aid something that was never set up right and no one has EVER really given a straight shooter solution to the problems...

Todd_33

I broke down and cracked a valve to sample the system. Clear with a distinct anti freeze smell.. 10 years on it, no chemistry ever done it. No brown rust at all...

I guess I will never know..

Derheatmeister

Clear Fluid

If the fluid is clear and has no rust that is a good,also your expansion tank is the original one

I will know in a couple days when i can make it to Leadville looking forward to it!

Maybe i can find some kinda information on the tube?? Richard

Possible ID

There is/was a pipe on the market called Hydronic Alternatives. It is a 5 layer pipe with an oxygen barrier, and is silver in color. Some of the info on the pipe is: PEOC-Plus PE-RT Dowlex 2388, DIN 4726, ISO 10508. Rated as 90psi at 180°F Made in Germany

Hope this helps!

Right,

no corrosion in the system is a good sign!

I have a roll of that PERT pipe, but I think it's black.

Mark_7

Looks like Infloor pipe which being that old it would not have a barrier.

Burnham Mega Steam install?

I may not do this install myself, but I am trying to understand it better. Here is my situation. I had a 70 year old oil steam unit that was 2000 lbs. when I finally removed it. It may have been 10% efficient at best. Most of the heat ran up the chimney. When I separated the sections, the bottom 2" connections were rusted with sediment almost solid.
My house is 2600 sf. I did a heat loss and came up with 46,000 btu's. EDR calculation came out to 300 sf (72,000 btu). The boiler I think I need is the Burnham Mega Steam 396. What other calculations do I need to take into account. Is this too small of a unit? Also, I have attached a diagram I created to understand the supply and return.

Some numbers found

What appears to be a SA in a small circle followed by what seems to be 613/R5

It is clear, if you shine a light through it it is opaque. The silver appears from when the gypcreted the floors..

That it does....

But one thing for sure, you have THE right techno-mechanic in Richard working on it. I'd (HAVE) trust him with my life.

Actually, in my 35 years of hydronicing, I have never seen PB in anything but grey, not clear. ANd it usually has so much pigmentation that you cannot shine a light through it. I suspect you have some grade of PEX, and if you can not determine whether it has a barrier or not, assume it doesn't.
