Heating pipes

Terrendis’ comprehensive heating range contains pre-insulated single and double (flow and return) cross-linked polyethylene (PE-Xa) carrier pipes with oxygen-diffusion barrier.

The pipe systems are designed to transport heating water up to 95°C, at a maximum working pressure of 6 bar (PN6).

Terrendis’ complete heating assortment includes pre-insulated pipe solutions for buried networks with heating capacities ranging from the single digit kW up to 1 MW.

The multi-layer thermal insulation is made from cross-linked, microcellular polyethylene (PE-X) foam with a water-repellent closed

cell structure, reducing heat loss to a minimum in underground distribution networks.

Terrendis’ heating range is ideally suited for district heating schemes, serving residential and commercial complexes from a central heat source:

  • Traditional fossil fuels (Oil, natural gas, and coal);
  • Biomass/Biogas cogeneration plants;
  • Renewable energies;
  • Etc…

Terrendis’ pre-insulated heating pipes can also be used in individual central heating applications (e.g. to connect a domestic heating system to its dedicated boiler located in a remote utility room).
