Mixergy at Hampton Court Palace: featured in Barclays Climate Ventures' latest 'In the Field' film
Barclays Climate Ventures has released a new film featuring our work at Hampton Court Palace, part of their ‘In the Field’ series, which follows the climate technology companies in their portfolio into the buildings and landscapes where their work is being put to the test.
Hampton Court Palace welcomes more than half a million visitors a year, and the demands that places on the building’s hot water system are significant. Kitchens, washrooms and visitor facilities all need reliable supply, and demand swings sharply across the day and the season.
That kind of variable load is exactly where conventional hot water systems struggle. They tend to heat large volumes of water continuously, regardless of whether anyone needs it, which drives up energy use and carbon. At a listed building like Hampton Court Palace, the usual response of stripping out and replacing infrastructure is rarely available. Every intervention has to protect the historic fabric.
This is where intelligent hot water storage offers a route forward. Our cylinders use sensing and machine learning to heat only what is needed, when it is needed, and they install as like-for-like replacements with no changes required to the building itself. For an estate like Hampton Court Palace, that combination matters.
The film captures this in conversation between Steven Poulter, Head of Barclays Climate Ventures, Jen Stone, Head of Sustainability at Historic Royal Palaces, and our CEO/CTO and Co-Founder Dr Pete Armstrong. Together they walk through what the technology is doing at the palace, and why hot water has become such a useful place to start when decarbonising a complex building.
One of the points Pete explores in the film is the idea of the cylinder as a hot water battery. By storing energy as heat at times when grid supply is plentiful and renewable generation is high, the system shifts demand away from peak periods. The hot water is there when visitors and staff need it, and the way it gets there does more to support the wider energy system.
The Hampton Court Palace project also reflects the role Barclays Climate Ventures has played in our growth. Their support has gone beyond capital. They have actively facilitated partnerships and helped connect British climate technology with the organisations best placed to put it to work at scale. Heritage decarbonisation is one of the harder problems in the built environment, and getting the right partners in the same room is often where progress starts.
