evaluation of existing hydronic system

eric_9

What is the quality of the components of my 8 years old hydronic system and what should I do to prevent problems in the system? Is there anything that needs to be changed ASAP?
Here are the components: Slant/Fin hot water boiler, Watts #ET-30 expansion tank, Comfort-Jass by Tam, and PolyB tubing?
Thanks.

did you say ...

PolyB tubing? Is there any kind of oxygen barrier in your tubing?

You could take a water sample form the system and have it tested. This could help.

Post some pictures.

Without looking at it in the real world we would only be taking a wild guess.

polyb tubing

Yes, it is polyB tubing without oxygen barrier- I thought all polyB tubing are non-oxygen barriered? There are copper tubings running from wall to Watts expansion tank. House was built in 1997.

Have ..

the water tested.

Are your pumps iron body pumps? The boiler is cast Iron correct?

You could have problems caused by oxygen permeation. Oxygen and cast iron will cause rust and corrosion. If you had all nonferrous parts in the system and a heat exchanger to separate the boiler and the polyb system then you could be o.k.

Good luck,
Joe

replace system parts now?

Would you replace ferrous parts of system and add another heat exchanger now? What is the likelihood that this will prevent future problems?

you need to get

a heating pro to the house to evaluate the situation. I can't do it on the ineternet.

good luck

Cleaning and treament

of your system would be a good idea. This would extend the life of your system and help to prevent future problems.
Check out our web site www.rhomarwater.com under hydronic products. Our cleaner and treatment were specifically formulated for use in hydronic systems.

I agree you would be well advised to have your system checked out and a sample of the water tested.

one option would...

be to replace the ferrous parts w/non ferrous parts(cost more), purge/clean the system and replace the boiler with a non ferrous 90+ boiler like a munchkin or a w/m ultra. This would create a savings in your gas bill wich would offset the added cost of non ferrous components.

I belive that damage has been done to the system by oxygen permiation, but how much will be hard to tell.
