The American EcoFlow has launched a new air-to-water heat pump for residential applications. The new product, equipped with R290 refrigerant, is available in 9 kW and 20 kW versions. The manufacturer has also developed a new smart immersion heater that uses excess solar energy to heat water. It is compatible with all available rooftop photovoltaic systems.
EcoFlow introduced new solar-to-heat smart heating solutions, the PowerHeat air-to-water heat pump and the PowerGlow smart immersion heater, at Solar Solutions Bremen 2024 in Germany this week.
The company said its smart solar heating solutions are designed to integrate into the EcoFlow Residential Smart Energy Ecosystem, offering users energy independence and reduced energy expenses.
“Thanks to its compatibility with PowerOcean series solar storage systems, EcoFlow smart heating solutions allow users to harness the power of solar energy for home air conditioning and water heating, providing a sustainable and cost-effective alternative to traditional heating methods, such as gas and oil,” the company stated.
The EcoFlow PowerHeat air-to-water heat pump, equipped with R290 refrigerant, is available in 9 kW and 20 kW versions. The system supports single-phase and three-phase connections.
The smallest device measures 1,263 mm x 440 mm x 875 mm and weighs 115 kg. The largest variant measures 1,263 mm x 440 mm x 1,375 mm and weighs 180 kg, according to the company.
The smallest heat pump has a cooling capacity of 1.53 kW to 5.96 kW, while the largest ranges from 4.40 kW to 14.40 kW. Heating capacity ranges from 3.50 kW to 8.81 kW for the smallest system, and from 6.70 kW to 20.36 kW for the largest version. The inlet water temperature is 30 ºC and the outlet water temperature is 35 ºC.
At higher water temperatures, 50 ºC at the inlet and 55 ºC at the outlet, the heating power ranges between 3.15 kW and 7.98 kW for the small system and between 5.80 kW and 18.48 kW for the big system. The maximum outlet water temperature in both cases is 75 ºC.
The smallest system has an input voltage of 220 V to 240 V and a maximum input power of 4 kW. The 20 kW system has an input voltage of 380 V to 415 V and a maximum input power of 6.8 kW.
The operating temperature range of both products is from -25 ºC to 43 ºC. The smallest system has a 2-liter expansion tank, and the largest version has a 5-liter expansion tank.
In addition to the new heat pump, EcoFlow has also introduced its new PowerGlow smart immersion heater as a solution for heating water with surplus photovoltaic energy.
The system can work in combination with the EcoFlow PowerOcean system or third-party photovoltaic systems, and energy usage scheduling is managed through the EcoFlow app. It is available in three versions: 3.5 kW, 6 kW and 9 kW. All versions offer an efficiency greater than 99% at nominal power.
The 3.5 kW system is available in single-phase and three-phase variants, while the other two systems only offer three-phase connections. They have an operating temperature range of 0ºC to 40ºC in the housing and a storage temperature range of -20ºC to 70ºC. The length of the heating bar ranges from 375mm to 550mm and the entire system weighs between 2.5kg and 3kg.
The PowerGlow smart immersion heater will be available in May, while the PowerHeat air-to-water heat pump will hit the market at the end of June, EcoFlow said in a press release. |
