The Danish company said its configurable CO2 system delivers up to 4.8 MW per unit and is scalable to 50 MW for large industrial and commercial projects. The units offer hot water output of up to 95 C and compatibility with complex installations such as food processing, district heating, and commercial buildings.

The Italian heating solutions provider said its new Nuos Plus S2 Wi-Fi heat pump system offers up to 80% energy savings and a coefficient of performance of up to 3.51.

Lithuania-based Refra has launched its Oasis series of water-to-water heat pumps and chillers, offering capacities from 34 kW to 600 kW for small to large commercial and industrial applications. Featuring propane refrigerant, inverter-controlled compressors, and modular multi-circuit design, the units can reach a coefficient of performance of up to 5.1.

The Korean manufacturer has expanded its Therma V R290 heat pump line with three indoor unit options to improve installation flexibility. The new products are designed to deliver heating performance at ambient temperatures as low as -28 C and domestic hot water output of up to 75 C.

Heat pumps are increasingly used for domestic hot water in Europe due to their efficiency and compatibility with solar power, but their lower operating temperatures can create conditions where Legionella pneumophila may grow if systems are poorly designed. Proper hydraulic design, temperature control, and periodic thermal disinfection ensure both high efficiency and safe, hygienic operation.

The new product line covers 124–644 kW in heating and 128–632 kW in cooling, operates down to -15 C, and supports various configurations with R454B or R410a refrigerants.

Daikin has introduced two new propane heat pump lines for industrial and district heating applications, combining monobloc units from 20 kW to 85 kW with modular systems scalable up to 2 MW.

Researchers in Spain have developed a dual-condenser air-to-water heat pump that shifts domestic hot water production to daylight hours, maximizing PV self-consumption. The prototype boosted solar energy use from 9.9% to 55.5% and achieved a peak coefficient of performance of 7.59 under PV-assisted operation.

The UK-based manufacturer has expanded its Ecomod 290HT range with a new 65 kW monobloc air-source heat pump using R290 refrigerant, offering flow temperatures up to 70 C, a COP of 4.6, and cascade capability of up to 7 units.

The Irish heating specialist has launched a high-temperature heat pump delivering up to 110 C hot water and heating capacities of 100 kW to 370 kW for industrial and district heating applications. The system achieves a coefficient of temperature of up to 4.63.
