District Heating Network Design & Engineering

At Design Tech Solutions, we specialise in the engineering design of district heating systems that are efficient, scalable, and future-ready. As the UK transitions to low-carbon energy, district heating networks are playing a vital role — and good design is where it all begins. From early feasibility to detailed route planning, our team supports public and private sector clients in delivering district heating schemes that perform over the long term. With every project, we aim to simplify the complex — combining technical rigour with real-world constructability.

Why Network Design Matters in District Heating

Overview of district heating network showing both heat sources and heat demands

District heating systems rely on an interconnected web of pipework, energy centres, and heat interfaces — and their success depends heavily on how they’re designed. Poor planning leads to inefficiencies, cost overruns, and long-term performance issues.

At DTS, we approach design with a dual lens: technical accuracy and practical delivery. Whether it's navigating existing utilities, assessing elevation and flow considerations, or integrating renewable heat sources, we ensure each design decision supports the wider goals of cost, carbon, and compliance.

How We Design District Heating Networks at DTS

We embed best practice engineering into every stage of network design — ensuring resilience, efficiency, and low operational risk.

  • Feasibility Studies & Early Concept Design
    We assess heat demand, energy sources, and routing options to shape viable, fundable schemes.

  • 3D Modelling & Pipe Routing
    Using CAD and BIM tools, we model networks in detail — optimising layouts and avoiding conflicts with existing infrastructure.

  • Integration of Low-Carbon Heat Sources
    We support integration with heat pumps, waste heat, CHP, and future-proof connections for geothermal or hydrogen sources.

  • Hydraulic Modelling & Flow Analysis
    We model temperature loss, pressure drops, and pump sizing to ensure thermal efficiency across every metre of pipework.

  • Detailed Design & Drawings
    From construction-ready schematics to as-builts, we provide accurate outputs to guide procurement and delivery.

FAQ

What is district heating network design? +
It’s the process of planning, modelling, and specifying the infrastructure required to deliver heat through underground pipes from a central energy source to multiple buildings.
When should network design begin? +
Ideally at RIBA Stage 1 or 2. Early input helps shape routing, feasibility, and integration with planning requirements.
Do you provide CAD or BIM models? +
Yes. All detailed design work is supported by CAD drawings or 3D modelling depending on the project scope.
How does DTS ensure design meets regulations? +
We align our work with CIBSE CP1, HNTAS, and local authority guidance — ensuring designs are compliant and deliverable.

Industry Frameworks We Work Within

RIBA-booklet-for-district-heating-deaign-process

We help clients meet technical and regulatory standards that shape the design and delivery of heat networks in the UK, including:

  • CIBSE CP1 – Code of Practice for Heat Networks

  • Heat Network Technical Assurance Scheme (HNTAS) – Design and performance verification

  • RIBA Plan of Work – Aligned deliverables across every stage

  • Local Authority Design Guides – Ensuring integration with planning and environmental requirements

Our designs are created to meet — and exceed — these frameworks.
