Heata installs rented business servers in UK homes and routes their waste heat into hot-water cylinders, reducing gas-heating demand. It says it pays for additional electricity and aims to provide about 80% of the heat for a home's heating system.
The system requires fast broadband for data routing and works only with vented hot-water cylinders; unvented, pressurised cylinders are incompatible. Heata says waste heat from a single data centre could provide hot water for around 30,000 homes.
Wales-based Thermify is seeking trial customers for a different HeatHub system that uses a cluster of Raspberry Pi Compute Modules and replaces a home's boiler. The article says new homes will not be permitted to install gas boilers from 2027.
