Hydronic Air PEX Piping Deteriorating - Repipe or Install New Heating System?
 
I bought my house 7 years ago and for the past month have been getting leaks everywhere from my IPEX piping from my Hydronic Air heating system. Fix one, another leak appears. Every plumber's visit is adding up. In addition I have tenants in there and supposedly by law, I cannot turn off the heating system because I have to provide heat to them year round (even though it is summer). I already contact IPEX and if it is determined the pipe is bad they only warranty the materials. Which is peanuts because the money is all in the labor.

So the plumber says it looks like there are other leaks and parts of the pipe deteriorating and that I will need to repipe the whole house.

I am trying to figure out if I should repipe or just reinstall a whole new heating system. A neighbor across the street is looking into a split ductless system.

If I do repipe, how do I find someone good? My worst fear is repiping and then another 7 years from now I get all these leaks again.

My property manager is also suggesting I file a home insurance claim for this. I'm not sure if that is a good idea?

Any help or suggestions appreciated. Thanks in advance.

The pipe is leaking, or the fitting?

Is it an oxygen barrier pipe, or regular pipe for plumbing.

IPEX has a recall on their fittings.

The pipe is leaking (doesn't look like its a fitting problem). From what I understand it looks like a bubble is forming in the pipe and then the leak starts. Apparantley the other pipes also look like they are starting to deteriorate.

Seems a little quick to deteriorate after 7 years??

I am not sure if it's an oxgen barrier pipe or regular pipe for plumbing. It's PEX piping, so I am assuming regular pipe? The plumber replaced the bad part with "12-14 inches of pex line cut out and replaced using WIRSBO Pex with "shark" fittings ( i/2 inch)".

My property manager says he hasn't been able to find a radiant heat guy and keeps bringing his regular plumber back which concerns me, since I am thinking he needs to get someone with this specialty?

Some areas, it is the plumbers that do radiant heating. In others, regular HVAC companies do it also.

Pex comes in both flavors. Non oxygen barrier, and oxygen barrier.

Might be better off just pulling all new pex(oxygen barrier type). 7 years is usually a manufacturer defect problem.

OK, so if I do repipe everything, the type of PEX I should look into is oxygen barrier type? I will research on that some more.

I was debating if I should even keep my Hydronic Heating. I'm not sure if it will cost more to repipe or look into a different kind of heating source. I'm just so worried that I will get leaks again in the future, but I am assuming, given the new piping is made good and of quality material, I should have no issues.

New type of heating system. Will probably cost a lot more to install.

What is making the hot water for your heating system.

Some systems don't need oxygen barrier per say. But, they seem to hold up much better. And have fewer problems.

i have a gas hot water heating tank in the garage, that brings the water into the house, and then there's the Hydronic main unit that heats the water higher to provide the heat.

Set up sounds a little strange.
If the boiler is cast iron, or other type of ferrous material, the tubing must be oxygen barrier.

thanks for the tips!

so whats a good way to look for someone that will do a good job? any questions in particular i should ask, besides referral?

beenthere 06-25-2010 07:36 PM

Look for someone that installs radiant heat on a regular basis.
The pex manufacturers, and boiler manufactirers will have contractor listings. So you can see if they have any listed for your area.

Then get their references.
