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.

Kensol said its new air-to-water heat pump uses a Panasonic Inverter DC twin rotary compressor and is able to achieve a maximum water temperature of 60 C.

pv magazine speaks to Jan Rosenow, principal and director of European programs for the Regulatory Assistance Project (RAP), about Europe’s top heat pump markets. He says Poland, Slovakia, Sweden, Germany and Finland posted the strongest growth in 2022.

German company Mefa Befestigungs- und Montagetechnik has developed absorbers made of polypropylene that are intended to simplify the use of brine heat pumps. The novel technology should make it possible to combine multiple heat sources, including water, earth, air and also ice storage all within a single system.

The photovoltaic boiler can be easily be installed by the users themselves. The solar modules are connected to the boiler via an MC4 contact plug, and heat the water.

Dutch transmission system operator Tennet, which also serves Germany, is planning to create flexible electricity demand and reduce grid congestion by promoting the use of smarter heating systems and heat pumps that can also be powered by solar and wind energy. According to its experts, intelligent control of heat pumps may result in the creation of between 0.5 and 1 GW of temporary grid flexibility by 2030.
