Heata's UK 'data furnace' turns server waste heat into free hot water

UK company Heata installs rented servers in homes and routes their waste heat into the hot water supply. It covers any extra electricity used, and the setup can supply around 80% of a home's heating. Wales-based Thermify offers a similar HeatHub built on Raspberry Pi modules.

• Heata installs servers in homes and feeds their heat into the boiler
• The system covers about 80% of heating demand
• Heata pays for the extra electricity the mini server uses
• Only vented hot water cylinders work; unvented ones are incompatible
