Heat Pumps

Designed for commercial and multi-residential buildings, the Aqua‑G EVO heat pump can replace gas boilers, cascade up to eight units, and integrate with Panasonic’s complete HVAC ecosystem.

The Croatian government’s latest set of energy support measures includes new financing for residential solar, batteries and heat pumps, expected to support up to 15,000 applications, as well as an extension of existing electricity price subsidies for homeowners.

The Chinese manufacturer has unveiled a hybrid photovoltaic–geothermal heat pump system that uses solar electricity to directly power the unit, boosting efficiency and self-consumption. The 8–112 kW ground- and water-source system delivers heating, cooling, and domestic hot water with coefficients of performance often exceeding 4–5, while smart controls and the ground loop act as a thermal battery to optimize year-round performance.

Researchers in China demonstrated that integrating energy tower heat pumps with evaporator-side boilers, air-source heat pumps, or solar-assisted systems can significantly improve winter heating efficiency and economic performance in commercial buildings. Among the four configurations tested, the evaporator-side boiler and solar-assisted systems delivered the highest performance and energy savings, offering a sustainable, low-carbon alternative to conventional heating.

Analysis across 16 European countries finds an around 240,000 increase in the number of residential heat pump sales year-on-year. The European Heat Pump Association attributes the upward trend to governments stabilizing subsidy schemes.

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 Nexis solution combines a flexibly configurable hybrid inverter with a modular high-voltage battery offering up to 14 kW charging capacity per stack. The inverter delivers 8–20 kW AC power, supports up to 200% DC oversizing, and features IP65-rated design with integrated backup power.

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.
