Kaiflex insulation ​protects ground source heat pipes.

Modern ground source heat pump (GSHP) technology can heat homes without the need for a conventional boiler by simply moving existing heat indoors. Even in the middle of Winter heat pumps can compress energy from the environment up to useful temperatures.

Ground source heat pumps, increasingly used in combination with underfloor heating, pass a frost resistant refrigerant around a pipe loop buried outdoors. As the refrigerant passes through the loop it absorbs heat from the surrounding soil. Although the temperature change is tiny the GSHP unit is able to extract it by manipulating the refrigerant mechanically to trap and release latent heat.

Outdoors the buried heat loop pipe needs to absorb heat and should remain uninsulated but where the flow and return are close and where the pipe is above ground insulation should be applied to maximise system efficiency. Buried insulation must be able to resist moisture ingress and provide a resilient protective surface.

Complex GSHP systems, such as those in schools and hospitals, have more associated pipework in the plant room. Although heated by the ground the flow temperatures here are still below ambient and without insulation condensation can occur.

Insulation should be present in order that, in order to prevent condensation and maximise efficiency, is able to demonstrate the following attributes:


 

 

Resistant to moisture ingress

As a water resistant rubber material, Kaiflex is highly resistant to moisture ingress and will not allow water to easily compromise the material properties and performance.

Protective surface

Insulation can occasionally be subject to mechanical impact, rips and tears. Whether accidental or intentional these look unsightly and reduce the insulation performance. Kaiflex is available with highly resilient coverings that protect insulation against the most common causes of damage.

Insulates complex shapes

Available in highly flexible tubes and sheets, Kaiflex is easily cut to size and wrapped around even the most complex shapes without the need for specially produced bespoke items.

In-built water vapour barrier

The cumulative moisture resistance of the many layers of watertight closed cells is so great that Kaiflex has no need for an externally applied water vapour barrier - the vapour barrier is built in and cannot be easily compromised or pierced.
