Testimonals

From Scott K: "I have your PerformaFlex XT installed with my Hoss boiler and have tested temp loss with a proper thermowell set up. I lose less than 1" in my 180' run."

There's no comparison between XT and the other insulated pipes made for outdoor wood furnaces and other hydronic heating use. No matter which product or cost level PerformaFlex XT offers a superior package of performance, durability, and flexibility. For you that means:

  • Less Heat Loss and Fewer Trips To The Boiler
  • Confidence That You Have Installed the Best, No Worries.
  • Easier Install, Much More Flexible Than Urethane Style
  • Industry Best, Amazing Remediation Warranty Even Pays For Time And Trouble If There Is A Manufacturers Defect

We are happy to cut to the precise length you need from 50' to 475'.

Shipping is included with cut to order 100' plus orders to most states. Shipping for orders totaling less than 100' is $75.00 and is added at checkout.
