Happy Independence Day!
Our Customer Support will be closed today in honor of Independence Day. We will be back on Sunday to answer your questions.
I recently upgraded my heating system with a condensing boiler which required the upgrade to my chimney. I used Duravent Poly Pro system. I found it easy to use, the product is well engineered, easy to assemble. Gaskets and clamps provide sealed combustion system. And it's legal in NYC. The catalog for the entire product line is available on-line and the Duravent customer service actually answers the phone and provides technical support.
As far as supplyhouse.com where I purchase the product, these folks have it together. Free shipping after $99 and the returns are easy to make. Good work. Thanks.
