District heating is an energy system, consisting of a single central piece of equipment to heat several buildings, that is cheaper and more efficient than a separate heating / cooling system for each facility . Even greater efficiencies are achieved when heat and power are simultaneously produced through a cogeneration system.
District energy can provide one or more of the following services: heating, cooling, electricity, and mechanical shaft power. District energy also provides operational benefits and is better for the environment.
With this system, hot water is produced in a power station and distributed with a pipeline to the buildings. These pipes for hot water need a high stability to oxidation and to pressure, because of the extreme operating conditions and for the continuous flowing of hot water at a temperature higher than house heating.
To produce district heating pipes, a specific masterbatch (Catalyst PS/2) has been developed to enhance the physical and mechanical properties. PEX Polidan® pipes have been working for several years showing an excellent resistance to the high temperature and pressure of the water, and providing hundreds of houses in Northern Europe with district heating.
