The UK Department for Energy Security and Net Zero says the latest round for its Boiler Upgrade Scheme – an initiative awarding GBP 7,500 ($9,500) to families in England and Wales to replace traditional boilers for heat pumps – “surged” with a threefold increase in applications.

Daikin has released a line of residential air-to-air heat pumps, using difluoromethane (R32) as the refrigerant, with outdoor unit dimensions of 662 mm x 442 mm x 1022 mm. The output ranges from 2.5 kW to 3.5 kW, and the seasonal coefficient of performance (SCOP) is between 4.85 and 5.17.

The new product utlizes propane refrigerant with a lower global warming potential and has a seasonal coefficient of performance (SCOP) of over 5. According to the manufacturer, it can achieve a flow temperature of 75 C and 100% heating output at outside temperatures of -15 C.

German researchers measured a PV-powered heat pump with battery storage in a single-family home in Freiburg, Germany, for a period of a year. It features smart grid-ready tech that adjusts operations based on the grid.

Infinite Turbine has developed a heat pump turbine for residential and commercial applications, using PV or alternative electricity sources for simultaneous cooling and hydraulic power. The tech can be retrofitted with existing CO2 heat pump systems for air conditioning, hot water, and process heat.

Developed by scientists from the UK and Spain, the new model uses high spatiotemporal resolution weather data and data from heat pump field trials. It finds “significant regional differences” compared to a British nation-wide estimation.

EDF has purchased UK heat pump installer CB Heating for an undisclosed sum.

Intended for applications in commercial buildings, the new VRV 5 heat pumps have reportedly a 9.1% higher seasonal efficiency compared to the company’s previous models. The new products use difluoromethane (R32) as the refrigerant.

LG has formed a partnership with the University of Alaska Anchorage to conduct lab research and perform real-world testing of heat pump technologies, with a particular focus on Alaska’s extreme temperatures.

A British-Chinese research group has developed a novel heat pump concept consisting of a heat pump, the PCM tank, and tube solar heat collectors. Intended for demand shifting in space heating and domestic hot water (DHW) applications, the system is reportedly able to achieve a higher coefficient of performance than conventional heat pumps.
