Does a HP emit heat over all 24hrs?

I might have raised this before

Starting my journey with a Daikin ASHP

It’s a shame you have no evidence about the insulated ceiling. I have set the (3rd party) internal thermostat to 30°C, so that it continually calls for heat. All the balancing is done with the weather compensation. The weather compensation “curve” calls for water at 21°C if the outside temperature is 21°C or more, effectively switching the system off. Until then the system modulates down as far as it is capable, effectively reducing compression. Between times the system switches off. As you me…

The figures above are out of date now but the broad description is still accurate.
