Microflex Heat Pump

Microflex Heat Pump pre-insulated pipe is specifically designed for heat pump projects. The intelligent design of Microflex Heat Pump combines the supply and return pipes for heating/cooling with two corrugated pipes for mains and control cables in the same outer casing. The empty corrugated pipes allow safe routing of the cables. It provides significant advantages such as low-weight, hyper flexibility, robustness, and easy and rapid laying even over obstacles and around corners.

Mibec specialise in the supply of underground pre-insulated pipe for the energy efficient distribution of water for point-to-point and district heating projects throughout the UK. We are leading distributors of Microflex in the UK and Watts Premier Partners.

Connection of external heat pumps, e.g. Air-Water Monobloc heat pumps.


The insulating material used consists of cross-linked polyethylene foam. In addition to the excellent insulating properties, the closed-cell structure of the material ensures that there is only minimal water absorption. The material is CFC free.

The UV-resistant outer casing in dark blue color is made from PE-HD according to the “closed chamber” principle, protects the inner pipe as well as the insulating material from external impacts. The ribs of the corrugated outer cover are completely closed; water ingress due to superficial damage to the outer cover is therefore impossible.
