Airsys moves into heat reuse as ThermAI turns GPU servers into home heating - markets.businessinsider.com
Airsys, a global thermal management company, is leading investment in UK GPU compute company ThermAI to develop a distributed computing infrastructure that reuses server heat for home heating.
The HeatBridge system is built around ThermAI's LiquidDock server cassette, which uses Airsys' LiquidPack spray-cooling technology to capture heat from AI and research computing. This heat is then converted into heating and hot water at no cost to participating households.
ThermAI will unveil its HeatBridge system at SC26 in Chicago from November 17-19, showcasing how server heat can be utilized rather than simply vented away. The company has also closed a pre-seed funding round led by Airsys, with participation from venture capital firm Augur VC and angel investors.
Free heating for households
Participating households receive heating and hot water at no cost, with ThermAI also covering backup heating needs when required. With typical UK households paying around £144 monthly for utilities, this system could deliver substantial savings.
The initial rollout will focus on social housing, targeting deployment in 100 homes with UK social housing providers in 2027. This aligns with government efforts to bring all social rented homes in England to EPC band C by 2030 through the £15 billion Warm Homes Plan.
Decarbonizing homes should also make them more affordable to heat, not just improve EPC ratings.
Research applications
Professor Jonathan Hirst of the University of Nottingham's School of Chemistry has signed a letter of intent to participate in a ThermAI compute pilot, supporting GPU-intensive research including drug discovery and molecular dynamics.
ThermAI's FlightDeck platform provides worldwide access to UK-hosted GPU resources for AI, research and engineering workloads, combining repeatable jobs, reusable datasets and clear cost visibility in one workflow.
Scaling from homes to districts
For Airsys, a single home serves as a proving ground for a model designed to scale. The same spray-cooling technology could eventually recover heat from full deployments and feed it into district heat networks.
Each installation pairs a custom six-GPU ThermAI Node with HeatBridge. An Airsys heat exchanger moves recovered heat into a water circuit with outlet temperatures up to 60°C, stored in Sunamp heat batteries until needed. The servers are built by 2CRSi using NVIDIA RTX PRO 6000 Blackwell Server Edition GPUs.
