Deputy to the answer: the need to heat pipe cooling effect of a good pipe, PB pipe heat works well, resistance to stress is also very good, but prone to crack. However, due to PB in possession of a good insulating effect, and therefore not applicable in the geothermal heating.

In addition, some owners of the tube material itself is not very understanding, some are not particularly put a professional construction side as PB pipe PPR pipe or other pipe directly changed, so that after the direct connection of different materials, over time will be because the water pressure, and so hierarchical cause trouble.

Moreover, the most suitable for geothermal water pipes, for the present from a cost point of view, do geothermal heating time can choose PRT tube. Because of its high temperature, thermal effects are better, but also the most affordable, cost is not high, so majority of the owners of geothermal heating can be rest assured that purchase.
