The National Health Service operates one of the largest and most demanding building estates in the country, spanning hundreds of hospital sites, over 200 NHS trusts, and more than 6,000 GP practices in England alone. Then, there are an additional 17,000 existing care home properties, to which a further hundred on average are newly built every year. Across these estates, the need for reliable, resilient hot water and heating is non-negotiable, underpinning infection control, patient safety and comfort, catering, and day-to-day operations.
Yet much of this infrastructure is ageing and decreasing in efficiency with rising demand and new net-zero targets. As services expand beyond their original design capacity, existing plant rooms are being pushed harder, often without the space, budget, or downtime for full replacement. While national programmes promise new and upgraded primary and social care estates, the immediate challenge lies in modernising and decarbonising much of the existing infrastructure. This creates an urgent need for scalable, efficient technologies that can reduce carbon and running costs while maintaining the uncompromising performance standards healthcare settings depend on.
We recognise the critical importance of a sustainable healthcare system. As the world’s first national health system to commit to reaching net zero, the NHS has set ambitious targets to deliver net zero operation by 2040 for direct emissions (NHS Carbon Footprint) and by 2045 for emissions it can influence (NHS Carbon Footprint Plus). Not simply aspirational; such commitments are essential for protecting public health from the impacts of climate change and ensuring the long-term viability of our healthcare infrastructure. Commercially, the same goals apply, but social care has the additional restrictions of privately funding these goals.
Healthcare decarbonisation strategy depends on moving away, where possible, from gas-powered systems to low-carbon alternatives. This includes adopting renewable energy, such as installing on-site solar panels and exploring power purchase agreements for renewable electricity. Efforts to improve overall energy efficiency will not only include upgrading water and space heating, but also address lighting, ventilation systems, and enhancing building fabric with better insulation. But to achieve all this comes with considerable capital and ongoing operational expense.
Delivering Sustainable Hot Water Solutions for Healthcare
The starting point for many sustainability strategies lies with the fundamental necessity of hot water. Healthcare facilities have unique and demanding requirements for safe and appropriately heated water. While direct electric water heaters offer zero on-site emissions, their higher running costs can be a concern for large, continuously operating facilities. The challenge lies in finding responses that balance environmental responsibility with economic capability and, crucially, uninterrupted operational reliability.
As experts in commercial hot water and heating systems, Adveco is uniquely positioned to support building operators and owners towards decarbonisation goals. Our approach focuses on providing balanced and strategic hot water systems that integrate low-carbon technologies, ensuring both sustainability and operational resilience, whilst maximising investment and controlling ongoing running costs.
Whether advocating lower cost retrofit or designing and implementing bespoke low-carbon hot water systems, Adveco brings its unique blend of engineering-led sales and technical support to any project. Comprehensive design, that delivers necessary thermal optimisation for new build or existing structures leverages a wealth of technologies, familiar and new, from high-efficiency, intelligent gas systems to electric boilers, heat pumps, truly renewable solar thermal and necessary storage cylinders, controls and ancillaries. With a holistic approach such systems are capable of significantly offsetting a building’s annual energy requirements for hot water, offering a rapid return on investment.
We especially advocate hybrid hot water systems that combine the strengths of various technologies. Our award-winning FUSION system integrates a storage cylinder with an electric boiler and the option of an Air Source Heat Pump (ASHP). Highly efficient, ASHPs, when deployed correctly, will generate up to 70% of the necessary system energy as preheat, thereby significantly offsetting the energy demands and emissions of the electric boiler.
The benefits of a hybrid approach when delivering domestic hot water (DHW) to healthcare facilities are well understood. Most notably, significant carbon reduction is easily achievable, actively driving decarbonisation efforts across healthcare estates. Buildings also gain assured reliability since hybrid systems offer built-in redundancy and the option of extra, temporary back-up in the form of additional electric immersion, ensuring a continuous supply of critical hot water, vital for healthcare settings. This approach also aligns with evolving environmental regulations and sustainability standards to offer a future-proof option that supports versatile and changing planning.
The decarbonisation of the UK’s healthcare is a complex but achievable goal. It requires a focused approach, moving beyond traditional thinking to embrace innovative, integrated systems. Adveco is committed to partnering with NHS Trusts and care home providers, offering our expertise to design, supply, and support the provision hot water systems that meet the rigorous demands of healthcare environments. By working together, we can contribute to a healthier and more sustainable care system for generations to come.
