British Gas partners with heata on waste heat reuse for water trial

British Gas and cloud computing provider heata have partnered on a trial to explore how the use of a ‘virtual data centre’ can reuse waste heat from data processing for water heating.
heata’s model distributes cloud computing workloads to servers in homes. In a data centre, the heat generated during processing is a waste product, and energy-intensive cooling systems are required to stop the servers from overheating.
To overcome this, heata has created a ‘virtual data centre’ – a network of servers distributed in people’s homes. Each server is attached to the home’s hot water cylinder, and as they process data, the heat they generate is transferred into the water.
This reduces the energy needed to heat water in the home, and as this is typically provided by gas boilers, it reduces the amount of gas used, lowering the carbon impact. heata pays for the electricity the heata unit uses, which means the household pays less to heat their hot water.
Commenting in a release was Paul Lodwidge, Head of Energy Product & Propositions from British Gas: “Innovative projects like this are another example of how the UK is becoming a leader in cutting carbon emissions. heata is a true pioneer in the way it has developed a solution that can reuse waste heat and deliver significant cost and carbon savings.”

As part of a three-month trial, 10 heata units will be installed in the homes of British Gas employees, and the energy provider’s computing workloads will be processed on these units. As a result, British Gas will be providing free hot water for its own employees as a byproduct of their own cloud compute.
The trial will provide feedback around performance and customer experience, as well as demonstrating the associated CO2 and energy cost savings to further co-develop customer propositions in 2025.
According to heata, the devices can provide up to 4kWh of hot water per day.
Chris Jordan, Co-founder of heata said: “We’ve created a solution that enables us to reuse the waste heat from cloud compute to provide free hot water for families in our communities.
“Our reliance on data centres is only going to grow, as they are fundamental to training and running artificial intelligence. By thinking differently about how we build and use data processing infrastructure, we can use a byproduct of this boom to help support our communities and reduce the carbon impact of compute at the same time.”
Added Jordan: “This trial with British Gas is an exciting step and we hope other businesses will follow suit. With a small change to where they place their data processing, businesses throughout the UK could be supporting their communities as a byproduct of their cloud computing.”
