MAXX-R Underground Pipe Insulation System

The flexible and economical MAXX-R Pipe Insulation System is a revolution in underground pipe insulation for wood burning outdoor boilers and furnaces. Until now dealers, contractors and homeowners have had to choose between cheap, poorly designed “home-made” insulation and expensive, hard-to-handle, metric sized, prefabricated pipe-in-pipe systems. MAXX-R, a system that gives you the performance you need, the price you can afford... And it’s easy to install!

Features and Benefits

Easy to Install
Ditch machine friendly. No need to dig up your entire yard. Cut your ditch AROUND obstacles and lay the MAXX-R insulation and pipe in the ditch. Then simply backfill and go.
Choose Your Own Pipe
Choose between 1” or smaller PEX type pipe (with or without O2 barrier). No need for hard-to-find (EXPENSIVE) special fittings..
MAXXimum R-Value
MAXXimum real life performance. Minimum of 1-3/4” closed cell polyethylene foam wall protects high temperature pipe from cold/frozen soil or air (temporary installation). See Performance chart in Specs for details.
Run Long Distances
Separation of FEED and RETURN lines assures hotter water to the home. Separating the feed and return lines with a minimum of ½” insulation prevent short circuiting of heat from the feed line to the return line. Without this feature, the water temperature at the home will be lower.
