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.

ThermoPEX insulated piping saves energy and maximizes efficiency by keeping heat loss to a minimum. Greater system efficiency maximizes the delivery of heat from each pound of wood. Reduces wood consumption.
