A heat pump arrangement including a first heat pump through which a first fluid flows, a second heat pump through which a second fluid flows, and a heat exchanger to transfer heat from the first fluid to the second fluid. The heat is transferred from the first fluid to the second fluid at a fluid temperature of at least 120° C. for the second fluid. The first fluid and the second fluid each have a volumetric heating capacity of at least 500 kJ/m3 when the heat is transferred from the first fluid to the second fluid. Useful heat is extracted from the second fluid at a fluid temperature of at least 120° C. for the second fluid, and the first fluid and the second fluid each have a volumetric heating capacity of at least 500 kJ/m3 when the useful heat is extracted. |
