Modern heat-pumps have no problem achieving high efficiencies when heating hot water.
Even in the middle of Winter in Scotland we're seeing COPs of 3.8 for the hot water cycle.
That's 3.8 more hot water than we'd achieve with just immersion heater. Would be crazy not to use a heat-pump.

We have a air-source heat-pump and it provide ALL our hot water. It's even capable of heating it to 70C if required.
You really do need to find sources basic on facts.
Right now it's running the hot water cycle where it's heating up the 250L Hot Water cylinder to 46C. We bump this higher during high demand (kids all home.)
So far today it's generated 19kWh of hot water using 5kWh of electricity, with a COP of 3.8.
It's been down to -6C this this month and saw no problems with household heating and hot water cycles.
How about the noise levels? They seem to have mythical status for disturbance of the peace
