heat pump

Mitsubishi has released a cascaded air source heat pump that can produce between 7.8 kW and 640 kW of heat. It is reportedly able to generate hot water at a temperature of up to 70 C without boost heaters.

The Irish government wants to introduce an unspecified renewable energy quota for the heating sector by 2024. The Sustainable Energy Authority of Ireland (SEAI) recently predicted that heat pumps could cover 20% of the country’s heating demand in 2030.

A new Regulatory Assistance Project (RAP) study shows there is a strong economic case for owning and operating heat pumps in Poland, which was Europe’s fastest-growing market in 2021. Air-to-water heat pumps cost about €8,000 ($8,210) in the country, with lifetime operating costs estimated at €12,500.

A new EU-funded project aims to show how heat pump technologies could supply various industrial processes with heat in the 90 C to 160 C temperature range. It also looks at how heat can be extracted from renewable sources like solar thermal, as well as ambient heat and industrial waste heat.

Carrier will soon begin field tests for a prototype air-source heat pump for cold climates. It is designed to provide high-efficiency heating performance in harsh climates with temperatures equal or below negative 29 degrees Celsius, while being grid-interactive. The US-based heating tech specialist expects to commercialize the solution by 2024.

A roof-mounted air source heat pump has reportedly been installed for the first time in the United Kingdom, as part of a pilot project at the University of Salford. The performance of the 200 kg Bosch 3400i Hydrotop will be compared to a similar unit mounted on the wall of a home.

The Japan-based manufacturing company has revealed plans to increase fivefold its production of heat pumps at its facility in Czechia by 2025.

Sprsun has developed a monobloc heat pump that is reportedly easier and faster to install. The product features a 3 kW/220 V electric heater, a water pump, an expansion tank measuring 5 liters, a three-way valve, and an 18 A AC contactor.

Scientists at Germany’s Fraunhofer Institute ISE and a consortium of heat pump manufacturers have achieved a new efficiency record in their development of a low-refrigerant propane refrigeration circuit. The device has a heating capacity of 12.8 kW with only 124 grams of propane, amounting to a refrigerant charge of approximately 10g/kW, compared to 60g/kW for commercially available devices.

Panasonic’s new heat pump can supply domestic hot water, heating and cooling from a single, integrated unit. It can also synchronize with the Japanese company’s PV panels and its CZ-NS4P technology printed circuit board technology, while also ensuring smart-grid compatibility.
