1" oxygen barrier PEX tubing typically replaces copper pipes when running supply and return lines to a heat source, a PEX manifold, a buffer/storage tank, etc.
It is most widely used for installing outdoor wood furnaces and is well suited for direct underground burial in a trench (with proper thermal insulation provided).
Q: How deep should the trench be?
A: The depth of the trench is generally determined by ground freezing level in your area. Tubing must always be buried below this level to prevent the water inside from freezing if the system is off. The colder the climate, the deeper the trench should be.
