I’m sure you can think of some immediate uses for this flexible pre-insulated Rhinoflex pipe. The dual pipe version holds two lengths of cross-linked PEX, and is available in lengths up to 1,000 feet. It can be used above or below grade, or even laid under water (if weighted down). The product is made Rovanco Piping, based in Illinois. The tubing can handle temperatures from -20 to 204 F, so it’s suitable for geothermal, solar hot water, or any project where heat loss over distance is an issue.
