Low-Carbon Heat Sources & Generation

Low-carbon heat generation is at the heart of the UK’s net zero strategy — and for many developers, funding bodies, and councils, it’s no longer optional.

At Design Tech Solutions, we help clients integrate modern, renewable, and recoverable heat sources into their networks. From heat pump-first design to solar thermal and hybrid systems, we engineer for both carbon reduction and buildability.

Why Low-Carbon Heat Matters in District Heating

diagram-of-low-carbon-district-energy-network

The UK government has committed to decarbonising heat — and district energy networks are a major part of that transition.

Whether your project is chasing PSDS, HNIP, LEVI or BREEAM targets, your heat source strategy will make or break your carbon case. DTS supports design teams to:

  • Integrate ASHPs and GSHPs at the right scale

  • Capture usable waste heat

  • Use solar thermal for DHW topping

  • Combine sources for resilience

  • Ensure outputs match planning and compliance requirements

FAQ

What is considered a low-carbon heat source? +
Typically, air and ground source heat pumps, solar thermal, waste heat recovery, and some CHP setups depending on grid carbon factors.
Do I need to use multiple sources? +
Not always — but combining sources often improves carbon performance, resilience, and eligibility for public funding.
Can you model how a heat source performs in different seasons? +
Yes — we model seasonal performance, COP, and load profiles to ensure each source is effective and efficient.
Can DTS help with public sector funding applications? +
Yes — we regularly support clients applying for PSDS and HNIP with layouts, performance data, and compliance summaries.

How We Deliver Low-Carbon Heat Design at DTS

Source Evaluation & Feasibility
We compare cost, carbon, and footprint for different generation strategies — including hybrid options.

Load & Performance Modelling
We simulate demand profiles, daily cycles, and flow/return performance to size each source correctly.

Controls Integration
We define sequencing and BMS logic that allows smart switching between sources based on load, time, or tariff.

Modular & Scalable Layouts
We build in flexibility for future add-ons or upgrades — including stubs, zones, and control expansion.

Funding-Ready Documentation
We provide performance specs and layouts to support PSDS, HNIP, or private sector funding applications.
