Ait-Group launches residential heat pumps with low propane charge
Germany’s Ait Group has introduced residential ground-source heat pumps using less than 150 grams of propane, based on results from the Fraunhofer ISE LC150 research project. The new systems deliver up to 6 kW of heating with a seasonal coefficient of performance of 5.14.
Panasonic launches new domestic hot water heat pump
The Aquarea DHW Heat Pump utilizes propane as the refrigerant and is reportedly able to reach maximum temperatures of 65 C. The standalone unit supports PV contact and is compatible with external recirculation pumps.
European heat pump customers face ‘fragmented’ installation journey
Apricum says in a new white paper that despite rising demand for combined energy systems with heat pumps in Europe, the installation process remains fragmented and difficult for customers.
Combining PV-driven heat pumps with district heating in multi-apartment buildings
An international research group has investigated how PV-powered heat pumps and district heating could be combined to heat a multi-apartment building in Sweden and have found that, of the three combinations they evaluated, relying on heat pumps as the primary heat source was the “most beneficial solution” in terms of operating costs and environmental impact.
French company offers router capable of redirecting surplus solar to water heating
French energy cooperative Solarcoop has launched a solar router that redirects surplus photovoltaic power from self-consumption systems to electric water heaters or other resistive loads, and can also control additional devices such as heat pumps.
Manitoba launches retrofit program to cut home heating costs
The Canadian province of Manitoba has launched the Affordable Home Energy Program to support ground-source heat pump adoption in electrically heated homes. The initiative, run by Efficiency Manitoba, offers no-upfront-cost options and could cut household electricity bills by up to CAD 1,000 ($730) per year.
Researchers demonstrate technical feasibility of retrofitting PV-driven heat pumps in multi-family buildings
A research group led by Germany’s Fraunhofer ISE has conducted what it describes as the first empirical study on PV-assisted two-stage HP systems in existing multi-family buildings. Its findings show that substantial PV electricity exports result in greater avoided non-renewable primary energy use.
Lennox launches residential heat pump with space-saving design
The US-based company said its new EL18KSLV Side Discharge Heat Pump uses R-454B as the refrigerant and has a size ranging from 2 tons to 5 tons.
Daikin launches new single-zone heat pumps for residential use
The new Oterra 115V heat pumps use difluoromethane (R32) as the refrigerant and have a heating capacity of 9,000 BTU/h to 12,000 BTU/h.
UK rooftop solar installations surge, new battery storage record set
Latest MCS data for small-scale renewables reveal a strong month for solar installations up to 50 kW, double-digit growth for battery energy storage installations and a milestone reached despite a muted month for heat pump installations.
