Heat Pump Truth or Myth#2 - Cycling uses a lot of power and ruins your COP
Posted by: @jamespaI understand that A2A heat pumps have better turndown than A2W thus sizing is less critical. I haven't seen the proof that this is true however.
I cannot state that I have noticed that our A2A heat pump can modulate to a lower output, but it can certainly respond much faster than an A2W heat pump and also may be more efficient, since it is cutting out at least one stage in the process.
