Smart energy, smarter business: unlocking the potential of heat networks

The way we heat our homes, offices and communities is changing. Across the UK, developers and housing providers are looking for ways to reduce carbon emissions, cut costs, and future-proof estates against rising energy demands. One of the most effective answers is already here: heat networks.

What are they?

Heat networks supply heating and hot water to multiple buildings from a shared energy source. Instead of every home or apartment block having its own boiler, a central plant (often powered by renewable technology) distributes energy efficiently through a connected system.

The benefits are clear:

• Lower operating costs thanks to shared infrastructure.

• Reduced carbon emissions, supporting net zero targets.

• Scalable design, adaptable to developments of all sizes.

• Future proofing with systems built for integration with renewable energy.

NIBE and Cetetherm

To support the UK’s growing demand for heat networks, NIBE has introduced Cetetherm technology to its portfolio. Well-established across Europe, Cetetherm Heat Interface Units (HIUs) and substations are designed to optimise performance, save space and integrate seamlessly with heat-pump-led networks.

Paired with NIBE’s market-leading heat pumps, Cetetherm gives developers and housing providers a reliable, scalable, end-to-end solution that is backed by our dedicated UK team.

Key features include:

• Proven space-saving HIUs for multi-dwelling and communal projects.

• Smart monitoring via myUplink.

• Compliance peace of mind with BESA and UK Reg4 approval.

• Compatibility with centralised heating systems.

A great example of this innovation in action is Bankside Yards, London’s landmark fossil fuel-free development. Cetetherm’s bespoke Maxi Select Special substations are powering eight buildings and 3.3 acres of public space without relying on a single fossil fuel.

Working with Price Building Services, the project demonstrates how heat networks can combine sustainability with comfort, efficiency and reliability. Bankside Yards isn’t just a development, it’s a statement of what’s possible when cities choose to grow sustainably.

What it means for communities

Heat networks aren’t just about large scale engineering, they’re about people. By connecting homes and buildings to a shared energy source, they can:

• make heating and hot water more reliable

• reduce energy bills by sharing resources more efficiently

• lower carbon emissions, helping every household contribute to climate goals

With innovations from NIBE and Cetetherm, heat networks show how smarter energy can create warmer, sustainable and healthier places to live.
