Factors influencing the choice of pre-insulated pipe systems for heat networks

If you are involved in any aspect of the development of pre-insulated heat networks - from feasibility and design through to installation, operation and maintenance (and you are not a manufacturer) - we'd be really grateful if you could complete the following seven, easy-to-complete questions (only clicks are required).

The survey is designed to explore which factors are most important when choosing a pre-insulated pipe system. The information gathered will be used to improve the performance and reliability of buried heat networks and help lower the cost of installation and operation.

It should only take around 1 - 2 minutes of your time and you don't need to provide any contact details. All data submitted will be kept totally anonymous.

We do intend to publish our findings and, should you wish, we’d be happy to provide you with a copy. Simply add your contact details to the second page of the survey form and we’ll make sure you receive a PDF.

Thank You
