Heata has developed a novel way to use the waste heat generated by servers: mounting them on domestic hot water tanks to cut energy bills for homeowners.
The company, whose services now include cloud compute, 3D rendering and ways to help landlords improve the efficiency of their housing stock, has hooked up with cloud provider Civo to offer the compute resources for running some workloads.
The hardware itself comprises a box that houses an ATX motherboard, with a large metal plate that is bonded to the domestic hot water tank using thermal epoxy. The plate is linked directly to the heatsinks on the CPUs, which in the trial are refurbished Xeon processors providing a total of 56 cores

About Heata - Heata began as an innovation project with British Gas; how could we help people living in fuel poverty? At the time there was a lot of coverage of Bitcoin mining and the vast quantities of energy miners were using, and the vast quantities of waste heat they were generating.
We wondered if we could utilise that waste heat to help, so we put a miner in a barrel of mineral oil and connected it up to a radiator to demonstrate the idea.
