Tarnoc’s turbine heat pump for old homes

Field notes

Tarnoc describes a reversed Brayton-cycle system in which a compressor, turbine, heat exchanger, and recovery stage operate on a single high-speed shaft. Its stated installation model keeps existing radiators and routes two air ducts through a roof or façade. The page identifies a 24 kW nominal, 30 kW maximum Combi Max configuration, claims supply temperatures up to 80°C, and lists deployments ranging from occupied Dutch homes to a hospital and a 1610 monument.
