Heat Pumps

Researchers in Austria have developed a new heat pump system for residential applications that reportedly achieves a coefficient of performance ranging from 2.82 to and 3.11 at an outdoor air temperature of 10 C and 20 C, respectively. They also found the system was able to supply the comfort conditions at all tested outdoor temperatures.

Havells India’s new 3.5 kW HP30 White Silver (300 L) system has a rated power input of 940 W. The manufacturer says it is ideal for large households.

Sixty-one heat pump industry chiefs have signed a letter to European Commission President Ursula von der Leyen, warning that delaying the EU Heat Pump Action Plan jeopardizes a key net-zero European industry.

New research from Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) has shown that combining rooftop PV systems with battery storage and heat pumps can improve heat pump efficiency while reducing reliance on grid electricity.

A new research project, thought to be the first to assess hydrogen as an energy source for heat pumps, has found that hydrogen-backed heat pumps could be an eco-friendly option for the building sector and support decarbonization in line with the UK’s net-zero targets.

Heat pump sales in Germany rose by more than 50% for the second year in a row in 2023, according to new figures from Bundesverband Wärmepumpe (BWP).

Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) says rising CO2 prices could make PV-powered heat pumps the most cost-effective choice for residential heating in the country, with heat pump uptake and district heating adoption proving more economical than replacing gas heating.

Researchers in China have designed a heat-driven thermoacoustic refrigerator/heat pump for room refrigeration. They said the system is easily combinable with PV energy and its coefficient of performance can reach up to 1.69.

The Netherlands-based home and office energy specialist raised capital to expand its offering into Italy, Spain, France, and Scandinavia. It is already active in Netherlands, Belgium, Germany, South Africa, and the United Kingdom.

US-based Johnson Controls says its new screw heat pump is able to deliver high-temperature hot water as high as 80 C. The system reportedly has a combined coefficient of performance of 4.1.
