Germany-based heating specialist Viessmann has developed a new line of air-source heat pumps for residential and commercial applications.
“The heat pump is designed for residential developments, small- to mid-scale commercial and public sector applications,” the manufacturer said. “All models provide both heating and active cooling within a single appliance and can be operated in bi- or monovalent modes.”
The Vitocal 2o0-A Pro comes in three versions, with heating outputs of 32 kW, 64 kW, and 128 kW, as well as a cooling capacity of 34 kW, 69 kW, and 139 kW.
The smallest product measures 775 mm x 1,260 mm x 2,115 mm and weighs 460 kg. The largest model measures 2,130 mm x 2,260 mm x 2,265 mm and weighs 1,850 kg.
All of the systems are reportedly able to provide a maximum flow temperature of 65 C at -7 C.
“This makes it ideal for modernization projects where integration with existing systems is required,” said Viessmann.
The company said the heat pump has a COP of up to 4.57 and a SCOP of up to 4.4. It uses refrigerant R407C, which is non-flammable and has a global warming potential (GWP) of 1774.
“This means units can be placed anywhere, including under windows or next to drains,” the company said. “Vibration decoupling also ensures the Vitocal 200-A Pro is exceptionally quiet in operation; at A7/W35 (outside air temperature 7o C and DHW 35o C), the total sound power level is 69.7 – 71.6 dB(A).”

All of the systems are reportedly able to provide a maximum flow temperature of 65 C at -7, the question is what is cop at -7. if its 1 it is substantially cheaper to use natural gas.
Yeah, if you live around the arctic circle or any other place with regular below-zero temps, not where all the ordinary people live.
Don’t know why you would think they can’t maintain a reasonable CoP at -7. There are already plenty of heat pumps on the market which do.
