HNTAS: Draft District Distribution Network technical specifications for new build heat networks
Draft Heat Network Technical Assurance Scheme (HNTAS) regulatory technical requirements to help heat network developers, contractors and operators demonstrate compliance.
Applies to England, Scotland and Wales
Documents
Details
These technical specifications for district distribution networks detail the draft requirements and technical obligations to be fulfilled as part of the upcoming Heat Network Technical Assurance Scheme (HNTAS).
A district distribution network is a pipework system that is external to buildings and which distributes thermal energy from one location within a heat network to another. This pipework can be comprised of buried or above-ground pipework and typically contains pipework, valves, heat meters and other ancillary equipment.
The specifications include the:
- technical requirements to be met
- performance monitoring requirements to be met
- key failures to be avoided
- evidence requirements to be provided to demonstrate conformity with HNTAS
They are for use by:
- heat network developers
- heat network designers
- heat network operators
- heat network equipment suppliers
- organisations within the heat network supply chain
These technical specifications correspond to the draft HNTAS assessment procedures for district distribution networks.
Next steps
We will run a change management process in parallel with the HNTAS technical standards consultation which will launch shortly.
We will make final versions of these documents available before the scheme starts.
