There is plenty of information regarding heat pump maximum output (and COP) for a variety of ambient and flow temperatures, but where do I find the minimum output?
Most state electronic (compressor speed) control, so I assume they can modulate down. But how much?
I have downloaded umpteen data sheets for the Vaillant arotherm+ 7kw model , but have been unable to find the information.
