heat pump

A set of amendments to Germany’s law that offer a rebate program for sustainable heating has come into effect on January 1st. The new rules grant rebates of up to 40% to help homeowners to buy and install heat pumps.

Equium has developed a new thermo-acoustic heat pump core that reportedly produces 3 kW to 4 kW of heat for every kilowatt of power it consumes. It says the refrigerant-free device could generate domestic hot water at temperatures of up to 80 C.

Germany’s Fraunhofer Institute for Solar Energy and a group of heat pump manufacturers have started a project to replace gas and oil heating systems in multi-family homes with propane heat pumps featuring low-charge propane (R290) as the refrigerant.

The Flemish government will halve the solar panels premium from a maximum of €1,500 ($1,594) in 2022 to €750 from Jan. 1, 2023. It will also end the home battery premium earlier than initially announced, from April 2023. The premium for heat pump boilers, on the other hand, will be retroactively doubled.

A UK research group has proposed the combination of solar-powered heat pumps and thermal storage based on phase-change materials for residential applications. They said such a system could facilitate cost savings of up to 39%.

Th International Energy Agency (IEA) says unsubsidized heat pumps are already competitive with gas boilers in mature markets like the United States, Canada, Japan, Italy, and China. It says global sales will soar to record levels by 2030.

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.
