How to improve indirect-expansion PVT-assisted heat pump performance
Scientists in Thailand have simulated an indirect-expansion photovoltaic-thermal-assisted heat pump and measured its performance under various cold water temperatures and tank sizes.
EU countries to pilot subscription model for heat pumps
An EU-funded project is introducing a heat pump on subscription model designed to increase the uptake of heat pumps in rented accommodation, with pilot actions planned in Austria, France and Greece.
Clivet releases residential air-to-air heat pump
The Italian manufacturer said its new Fullness heat pump system has a coefficient of performance of 2.8 and a seasonal energy efficiency ratio of 3.79.
Chinese scientists unveil thermoacoustic ultra-high temperature heat pump prototype
Researchers at the Chinese Academy of Sciences developed a thermoacoustic Stirling heat pump prototype that offers high thermal performance, a peak coefficient of performance of 1.68, and potential applications in high-temperature industrial processes, enabling zero-carbon heating for sectors like petrochemicals and metallurgy.
UK government backs more than 180,000 heat pump installations
Subsidy support has driven heat pump adoption, with the pace of deployment increasing since early 2024. Second largest subsidy scheme to be wound down in 2026 leaving expanded boiler upgrade scheme as dominant support mechanism. Full details on UK government’s Warm Homes plan expected in early 2026.
M-Tec launches modular propane heat pump for residential, commercial use
The new residential heat pump system can be configured modularly and requires less than 150 grams of refrigerant, which allows it to be installed indoors. The system integrates with M-Tec’s energy management platform and supports multiple heat sources, photovoltaics, and battery storage.
German startup installs industrial heat pump producing 139 C steam
German start-up SPH has installed its ThermBooster heat pump at Philip Morris International’s Italian factory, producing high-temperature steam at 139 C. The system boosts energy efficiency, cuts gas use by up to 50%, and recovers 20–30% of water from exhaust.
Enerin offers industrial heat pump delivering heat up to 250 C
The Norwegian industrial heat pump specialist said its HoegTemp system has a heat supply capacity of 0.2 MW to 5 MW and a coefficient of performance above 2 at high lifts.
Open-access online tool helps homeowners replace gas boilers with PV-driven heat pumps
Italian research agency Enea has created a web tool that assesses the feasibility of replacing residential gas boilers with heat pumps by providing an estimate of the potential energy and economic savings. The app also provides information on the technical specifications of the photovoltaic system necessary to meet the heat pump’s electricity demand.
European heat pump subsidies tightening, says EHPA
Analysis by the European Heat Pump Association finds several European countries have restricted available heat pump subsidies over the last two years, with the general trend moving towards targeted aid linked to low-income or energy performance.
