Solarwatt enters heat pump business with new energy management system
Solarwatt and Stiebel Eltron have agreed to cooperate on the development of heat pumps.
District heating via solar-powered heat pump using industrial waste heat
The Fraunhofer Institute for Solar Energy Systems is assessing how a solar-powered heat pump system that uses waste heat from a distillery at a low-temperature level could be used to provide district heating. Waste heat is injected into an ice storage tank, to which heat pumps are connected on the source side.
Residential heat pump produces water up to 75 C
Scientists in Spain have developed a new heat pump that can produce 6.49 kWh of heat for each kilowatt-hour of power it consumes. The device could generate hot water at a temperature of up to 75 C.
Large-scale, high-temperature heat pump for district heating
Vattenfall and Siemens Energy are building an 8MW heat pump for district heating applications in Berlin. The facility will be powered by wind and solar via the electrical grid and will provide heating and cooling to the local district heating network.
UK governments slashes VAT for residential PV, heat pumps to 0%
The new measure will come into force on April 1 and will be in place for five years.
1Komma5°, Enphase plan European virtual power plant relying on solar, storage, heat pumps and EV recharging
Through a strategic partnership, the two companies want to equip 1.5 million buildings in Europe with photovoltaics, storage systems, recharging solutions for electric vehicles, and heat pumps by 2030.
France lowers grid fee for solar up to 500 kW, heat pumps
According to the new provisions introduced by the French government, owners of PV systems with a capacity of up to 500 kW will pay a grid fee that is 40% of the current rate. As for heat pumps, their owners will pay only 20% of the fee.
Rotation heat pump for industrial applications
Austrian tech company ecop has developed a rotation heat pump with a reported coefficient of performance (COP) of 4.0 – 7.0. The 700 kW machine operates under temperatures of 150 degrees Celsius and is based on an anticlockwise running Joule process, during which there is no phase transition of the working medium that always remains gaseous.
Photovoltaic forced ventilated facade for applications with air source heat pumps
Scientists in Spain have designed a BIPV forced ventilated facade that can be used as support for heating and a domestic hot water (DHW) building system based on air source heat pumps (ASHPs). In the proposed system configuration, the heat pump is expected to cover building heating demand at all times, regardless of the performance of the solar array.
Panasonic launches solar heat pump solution for water heating
Panasonic has unveiled a new product in Japan with a PV-based charging function that uses a heat pump and hot water storage unit to save energy by maintaining bathwater temperatures at constant levels.
