Outdoor Wood Boiler (OWB) Insulated REHAU pipe is specially designed for the efficient transfer of hot water from outdoor wood boilers to residential and light commercial building such as barns and workshops. A flexible alternative to rigid pipe, OWB pipe offers ease of installation combined with the long-term performance of REHAU's 02 Barrier PEXa pipe for hydronic heating applications.

1 . CARRIER PIPES: transfers hot water through REHAU 02 Barrier PEXa pipe. Rated 180 degrees F at 100psi and backed by a 25 year warranty. PEXa contains the most consistent level of cross linking pex and can be used with virtually any connection system - compression, crimp or expansion.

2. POLYURETHANE FOAM: insulates the carrier pipes to maximized efficiency and save energy. Solidly filled makes it waterproof, un-crushable, and virtually un-measurable heat loss.

ThermoPEX is flexible pre-insulated piping that is ideal for use with outdoor wood furnaces. ThermoPEX consists of two 1-inch* oxygen barrier Central PEX lines or two 1-1/4 inch** oxygen barrier PEX lines (supply and return) that are insulated with high-density urethane insulation and a thick, durable, waterproof, polyethylene outer jacket.
