Heat Pumps

The Finnish company said its novel AmbiSteam system can produce process steam above 5 bar. It is based on the company’s SteamLevel heat pump technology.

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 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.

The EU’s third hydrogen auction is open for applications until Feb. 19, 2026, alongside a pilot auction for decarbonizing industrial process heat. The 2025 edition of the Net-Zero Technologies call is also underway, accepting applications until Apr. 23, 2026. Together, the three funding streams have a budget of €5.2 billion ($6.07 billion).

Latest boiler upgrade scheme (BUS) data reveals more than 100,000 applications for heat pump grants have been made since support scheme launched in May 2022. Demand has significantly increased in 2025, and the scheme was expanded in early November to include an air-to-air heat pump grant.

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.

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.

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.

Scientists in China have developed an optimized energy management strategy for a wind-PV hybrid heat pump system that uses both thermal and electric energy storage. Using different seasonal interaction management strategies, they simulated four operational cases.

The company’s demonstration centre in Dallas, Texas, showcases its Arcturus steam-generating heat pump, which it says is eight times more efficient than natural gas boilers and six times more efficient that electric boilers and thermal energy storage.
