Heat Pumps

The ETS2 Frontloading Facility will provide €3 billion ($3.5 billion) to sectors set to be covered by the EU’s new emissions trading system. It will support low- and middle-income households with the deployment of heat pumps and electric vehicles.

Dutch utility Eneco is testing low-noise air-to-water heat pumps from startup Whspr in around 20 homes, aiming to ease installation constraints near property boundaries. The systems reportedly achieve coefficients of performance of up to 5 and show up to 80% noise reduction in laboratory testing.

The South Korean giant said its new EHS All-in-One provides air heating and cooling, floor heating, and hot water from a single outdoor unit. It can supply hot water up to 65 C in below-zero weather.

Researchers in Hong Kong have developed a hybrid-energy heat pump that seamlessly combines absorption and compression cycles using crystallization-free ionic liquids, improving efficiency and reliability across varying solar conditions. Simulations in multiple Chinese cities show the system can significantly cut electricity use and cooling costs, making it promising for sustainable building cooling and future commercial scaling.

US-based Copeland has launched its Sensi Hydro sanitary water heat pump designed to provide energy-efficient hot water for hotels, commercial buildings, and public facilities. The units feature ZW scroll compressors, independent refrigerant circuits, and backup mode to ensure reliable hot water supply.

Axinar has launched SolBox, a direct PV water heating system that powers electric resistance accumulators without thermal collectors. It’s designed for homes and businesses, offering real-time monitoring, MPPT optimization, and automatic grid backup.

U.S. startup Quilt has introduced a new three-zone ductless heat pump for residential use, offering independent temperature control across three areas with a single outdoor unit. The system uses R32 (difluoromethane) as the refrigerant and can reportedly achieved a coefficient of performance of 4.2 at 8 C.

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.

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.

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.
