Insulated Underground Pipe
The characteristics that make rigid Insul-Seal a superior insulator for hot water lines has finally been translated into a flexible version retaining the positive benefits of the original product.
Flexsul-Seal is an elastomeric thermal insulation used to retard heat loss in hot water plumbing and dual hot waterline systems. The Flexsul-Seal system is designed to trap dead air, within an expanded closed cell structure, thus increasing its total R-Value and reducing Heat loss in cold underground burial. Thermal performance is achieved by sealing the 2-5/8" centered air space, in effect reducing the flow of air and increasing the total R-Value of 6 by and additional factor of 5-9.
Pex tubing carrying hot water needs room to expand and contract. Without needed
space to expand, Pex tubing call cull and add unneeded stress at its connections. With the Flexsul-Seal system Pex waterlines have sufficient room to expand and contract with no stress added to connections ends.
For your Outdoor furnace Installation it only make sense to use a quality product.
Outdoor wood Boilers can only operate at peak performance when used with a quality insulated piping system. A poor quality insulated system will require substantially more wood and also reduce the amount of heat delivered to heat your home. Flexsul-Seal carries along the tradition of high quality and high standards already established by its manufacturer, Insul-Seal Insulated PVC.
