Introduction: Why Pipe & Insulation Innovation Matters

Pipes are the backbone of any district heating system — but not all pipework is created equal. With growing pressure to improve thermal efficiency and reduce carbon impact, innovation in piping and insulation is playing a central role in future-ready heat network design.

At DTS, we stay on top of the latest developments in pre-insulated pipe systems, flexible polymers, and low-loss insulation, helping our clients improve performance, simplify installation, and future-proof their networks.

What’s Changing in Pipe & Insulation Technology?

New Core Materials
High-performance plastics and composite layers now offer flexibility, durability, and long service life — ideal for tight or retrofit routes.

Improved Insulation Foams
Next-gen PUR and PE-X foams dramatically reduce heat loss and can be tailored to specific temperature profiles.

Mechanical Joint Systems
Modern fittings reduce on-site welding, speed up installs, and improve future maintenance access.

Fire & Moisture Protection
Enhanced jacketing and barrier systems reduce condensation and improve fire performance in risers and plant rooms.

Modular Pre-Fabrication
Pre-insulated pipe kits (e.g. elbows, branches) are now available off the shelf, reducing site time and waste.

Design Considerations for Pipework Innovation

When specifying pipe systems, we help clients assess:

  • Operating temperature and pressure

  • Thermal losses and energy efficiency

  • Moisture protection and groundwater resistance

  • Installation method (direct bury, risers, suspended)

  • Embodied carbon and end-of-life recyclability

  • Warranty, supplier support, and service life

Our goal is to match technical performance with environmental responsibility — while keeping costs and logistics in check.

FAQ

Is steel or plastic better for district heating pipes? +
It depends on the application. Plastic is flexible and lightweight — great for lower temps and retrofits. Steel is often better for high temps and longer runs.
Can older networks be upgraded with new pipe systems? +
Yes — we help clients evaluate replacement options, route upgrades, and improve insulation during retrofit.
What insulation standard should I aim for? +
We typically design to meet or exceed CP1 and HNTAS guidance on insulation thickness and thermal performance.
Do pre-insulated pipes reduce install time? +
Yes — modular components and pre-cut kits can dramatically reduce labour and time on site.

DTS Expertise in Pipe & Insulation Specification

  • Pre-Insulated Pipe Layouts
    We produce detailed plans and sections aligned with supplier recommendations and CP1 standards.

  • Thermal Loss Calculations
    We assess the network for insulation performance and advise on payback for upgraded systems.

  • Material Evaluation & Selection
    We benchmark manufacturers based on service life, carbon footprint, warranty, and ease of install.

  • Retrofit Routing Support
    We help design risers and basement networks that minimise disturbance to existing infrastructure.
