Frequently Asked Questions
What does the DACH version mean?
The device, control system, and documentation are designed for the German-speaking market: menu navigation and documentation in German, mains connection 230 V / 50 Hz. This means the heat pump can be used in Germany, Austria, and Switzerland. Subsidies and registration requirements differ by country – your local installer will clarify this.
Why R290 and not R32 or R410A?
R290 is propane, a natural refrigerant with a global warming potential of 0.02 instead of several hundred. It is not subject to the shortage of fluorinated refrigerants and at the same time achieves higher flow temperatures – up to 75 °C here.
Does the 7 kW size fit my house?
The VWL 75/8.1 delivers 6.94 kW at -7 °C outside temperature and 35 °C flow. This is the typical size for a single-family house with a heating load of 7 to 9 kW, even partially renovated. The exact sizing is part of a heating load calculation according to EN 12831.
Can I continue to use old radiators with it?
Yes. With a flow of up to 75 °C, the aroTHERM plus reaches temperatures that can also serve older radiators. However, it only becomes efficient with a low flow – at 55 °C the efficiency is 142 %, at 35 °C it is 196 %.
How loud is the heat pump in operation?
57.4 dB(A) sound power at maximum, only 46.2 dB(A) in whisper mode at A7/W35. In night mode, it is 27.5 dB(A) at 3 m distance – quieter than a quiet living room.
What do I need in addition to the outdoor unit?
The aroTHERM plus is a monoblock; the complete refrigeration circuit is located outdoors. For a complete system, depending on the concept, a hydraulic station or a uniTOWER, a hot water storage tank, and the system control are added. We assemble the package as required.
