By prioritising copper in heat pump systems, stakeholders can meet the demands of today while anticipating the challenges of tomorrow, delivering homes that are not only compliant but also resilient and sustainable for generations to come
As the UK accelerates toward a net-zero future, the conversation around heating homes is undergoing a seismic shift. With the Future Homes Standard (FHS) set to take effect in 2025 and the Home Energy Model (HEM) redefining how energy efficiency is measured, low-carbon technologies like heat pumps are rapidly becoming central to residential construction and retrofit strategies.
The Copper Sustainability Partnership highlights the importance of integrating copper in heating systems to meet and exceed performance metrics. Its durability and compatibility with various technologies provide unparalleled versatility, ensuring that developers can adapt to future updates in legislation or energy models without significant overhauls.
Benefits of copper in heat pump installations
Heat pumps represent the frontline of the UK’s decarbonisation strategy. Their efficiency, safety, and performance are only as strong as the infrastructure that supports them. Heat pumps work by transferring heat from the air, ground, or water into a building, offering a highly efficient alternative to traditional heating methods. That’s where copper’s superior thermal conductivity and durability under pressure make it the material of choice for modern heating systems.
Unlike plastic pipes, copper enables rapid and efficient heat transfer, ensuring that heat pumps operate at peak performance, even in high-demand or colder environments. Withstanding higher pressures and temperatures with ease, copper provides the mechanical resilience needed for safer systems.
Crucially, copper eliminates fire risks associated with plastic pipes. The Plastic Under Fire campaign reveals that plastic pipe materials can ignite at temperatures as low as 210°C, releasing highly toxic fumes including hydrogen chloride gas, which pose serious health risks and complicate fire safety in buildings. Copper is non-combustible, does not emit toxic smoke and maintains its structural integrity even in extreme heat conditions.
Toxic fumes released from burning plastic are a major contributor to fire-related fatalities, accounting for approximately 60-70% of deaths in building fire incidents. Using copper piping dramatically reduces these risks, helping to safeguard occupants and improve fire safety compliance in both residential and commercial heat pump installations.
With the UK seeing a 63% increase in hydronic heat pump sales in 2024 and aiming for 600,000 annual installations by 2028, the infrastructure supporting these systems is under intense scrutiny. Heat pumps supported by copper piping are not just a choice, they’re a necessity for achieving long-term reliability and efficiency.
The UK’s Future Homes Standard and Home Energy Model are shaping the regulatory framework for heating solutions. By 2025, all new homes will need to comply with stringent standards focused on thermal efficiency, emissions, and overall energy usage. Copper systems seamlessly align with these goals, offering developers and contractors a proven pathway to compliance.
Copper’s ability to handle high pressures and temperatures ensures that heat pumps maintain peak performance under the most demanding conditions. This resilience also reduces the need for frequent maintenance, ensuring systems remain cost-effective and efficient over their lifetime.
Sustainable advantage in the industry
Copper’s role in sustainability extends beyond its performance in heating systems. As an infinitely recyclable material, copper supports circular economy principles, reducing waste and embodied carbon in the construction sector. It’s estimated that around two-thirds of the 550 million tonnes of copper produced since 1900 are still in use today.
Additionally, copper’s long service life reduces the need for replacement, aligning with sustainable building practices. Its natural antimicrobial properties further enhance its appeal in residential and commercial heating systems, promoting healthier living environments.
Research demonstrates that copper installations offer exceptional durability, with a lifespan well over 50 years. This longevity makes copper a cost-effective and environmentally responsible choice for developers and homeowners alike.
The UK’s transition to heat pumps is well underway, with major housing developments and retrofit projects showcasing the effectiveness of copper systems. From large-scale social housing projects in urban areas to bespoke rural homes, copper is enabling high-efficiency, low-carbon heating solutions across diverse settings.
For developers, contractors, and specifiers navigating the changing regulatory landscape, building future-ready homes requires future-ready materials. When it comes to integrating heat pumps into high-performance heating systems, copper delivers on every front. Its combination of technical superiority, environmental sustainability, and regulatory alignment ensures that copper will remain indispensable as the UK transitions to a greener, more efficient housing stock.
By prioritising copper in heat pump systems, stakeholders can meet the demands of today while anticipating the challenges of tomorrow, delivering homes that are not only compliant but also resilient and sustainable for generations to come.
