A Braintree couple, Terrence, 76, and Lesley Bridges, 75, have successfully implemented a new energy scheme in their home, reducing their heating costs to just £40 per month. They replaced their gas boiler with a data center comprising over 500 computer banks stored in their shed. This innovative system generates heat that is then channeled into their hot water system, resulting in substantial savings.

Previously, the Bridges were spending £375 monthly to heat their two-bedroom bungalow. However, since installing the data center in December 2024, their bills have significantly decreased to a range of £40 to £70. Mr. Bridges, a retired RAF sergeant, expressed relief at the newfound affordability and efficiency of their heating system, emphasizing the comfort it provides, especially for his wife who suffers from spinal stenosis.

The HeatHub data center, developed by Thermify as part of UK Power Networks’ SHIELD project, aims to assist low-income households in transitioning to a net-zero environment. By utilizing electricity efficiently, this technology not only reduces costs but also contributes to a cleaner energy future. The successful trial at the Bridges’ home has shown promising carbon reductions and cost savings, prompting plans to expand the initiative to more households in the upcoming phases of the project.
