A practical route to process-heat electrification
Industrial heat pumps can replace part of the fuel used for hot water, drying and low-pressure steam when a plant has a usable heat source and a process that needs heat at a suitable temperature. They are not a universal boiler replacement. The strongest projects connect a stable source of low-grade heat to a nearby and simultaneous demand.
Spain has a large food and drink sector, refrigerated logistics, dairies, wineries, paper production and other plants with heating and cooling loads. These are credible early markets because useful heat is often rejected by refrigeration, effluent, condensate or ventilation systems.
Why Spanish conditions do not settle feasibility
Climate helps some air-source duties but ambient temperature is rarely the main industrial question. Source temperature, sink temperature, annual operating hours, electricity and gas prices, grid capacity and the cost of modifying the process matter more.
A site study should identify heat flows before selecting equipment. Direct heat recovery through a heat exchanger should normally be considered before adding a heat pump, because heat that can be reused without compression is cheaper to move.
Spanish evidence is still emerging
Publicly documented Spanish industrial heat-pump cases remain less abundant than cases from northern Europe. The project database therefore separates Spanish evidence from international operating references rather than presenting foreign projects as if they occurred under Spanish commercial conditions.
The CIRQLAR project at Repsol's A Coruña refinery is a Spanish demonstration backed by the EU Innovation Fund. Its public description establishes the intended recovery of low-temperature refinery waste heat and upgrade to process steam. It does not yet provide the sustained operating figures needed for an independent annual-performance claim.
Technology readiness
Systems supplying below roughly 120°C are in commercial operation. The IEA reports that systems below 160°C are beginning to enter commercial operation, while higher temperature bands remain more dependent on demonstrations, prototypes and specific refrigerant cycles. A catalogue maximum temperature is not evidence that a machine will deliver the required capacity and efficiency at a plant's actual temperature lift.
