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.

Thermal expansion is absorbed within the system because the Central PEX, urethane insulation and the durable outer jacket are cast together. The corrugated design allows flexing for easier installation. ThermoPEX is a proven product and maintenance-free.
