摘要

The pipe has an assembly including a cooling and heat recovery system fixed on a large central pipe made of metal such as stainless steel or cast iron, where the system recovers heat by diffusion. The assembly is fixed firmly to a wall and/or a floor by fixing lugs. A copper pipe is wound contiguously over the entire length of the central pipe, where water flows through the copper pipe. The copper pipe and the central pipe are welded together by two rings at the ends of the pipes.
