New air-to-water heat pumps from Italy

Italian manufacturer Thermocold is offering new heat pumps with output ranging from 8 kW to 30 kW. They use propane as the refrigerant and reportedly have a seasonal coefficient of performance of up to 4.5.

New model to predict defrost cycles, behavior of air-sourced heat pumps in cold weather

UK-based researchers have developed a novel method to estimate the amount of defrost cycles a heat pump will experience in the winter and how much energy it would require to implement the cycles. The results of their simulation showed a strong relationship between the number of defrost cycles and the ambient temperature.

Up to 1,150 families sign up for UK heat pump scheme

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 unveils series of residential air-to-air heat pumps

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.

LG launches residential air-to-water propane heat pump

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.

High-resolution model to identify hourly usage patterns of residential heat pumps

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 acquires CB Heating

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