ᐅ How to Properly Adjust an Air-to-Water Heat Pump with Underfloor Heating

Hello,
I have been searching around and reading the manual for my Elco air-to-water heat pump, but I haven’t fully figured it out yet...
I have a manifold on the ground floor and first floor; the recommendation is to fully open everything, set all thermostats to maximum, and then adjust the heating curve on the heat pump low enough to roughly achieve the desired temperature.
Is that more or less correct?
At the moment, every thermostat (except bathroom/bedroom) is set to 20°C (68°F), and the temperature in each room is about 20.9°C (70°F) (bathroom slightly warmer, bedroom slightly cooler).
However, I’m surprised by the high electricity consumption — it has been 800 kWh in just 2 months.
135 m² (1455 sq ft) living area
Elco Split 7 kW
Circulation pump not yet connected
Thanks in advance

If no defrost water accumulates inside the unit and the drainage path from the heat pump itself remains clear, it’s not a big issue initially. But usually, that’s not the case; the water should also be directed away from the house.
Is the drain simply not yet connected to the drainage system? It looks like a PVC pipe (commonly used for underground drainage) still needs to be connected at the front, but it’s not visible in the picture. If that’s the case, I would first enlarge the hole where the small ice patch currently is so that water can drain over a larger area and doesn’t freeze up to the heat pump.

The outdoor unit usually has a condensate drain. Currently, it just drains onto the sloped ground, but this will likely change. It will either be connected to the drainage system or directed into a gravel bed for infiltration. The amount of water is not an issue right now, just a small puddle. It actually rains more here in two minutes. No need to worry.
The heat pump itself should defrost to operate efficiently.
