Hello everyone, I am currently optimizing my heat pump with halmi's help and just need a few opinions. Settings are as follows,
- ÜSV closed and ERR fully open
- Domestic hot water 48 degrees, hysteresis 6K
- Heating curve 27/21/0, hysteresis 2K for 1.5 days, which results in a target return temperature of 25.9 degrees
2-3 hours of heating operation and 4 hours break
Upper floor in degrees
- Child 2 21.2
- Child 1 20.9
- Bedroom 21.3
- Office 22.2
- Bathroom 21.5
Ground floor in degrees
- Living, kitchen, dining 23.9
- Wardrobe & hallway because of sliding door to living 23.5
- Guest bathroom 20.5
This results in 25 kWh per day just for the heat pump, which is too much for me.
Change since today 8:30 a.m.
- Domestic hot water 48 degrees, hysteresis 7K
- Heating curve 26.5/20.5/0, hysteresis 2K, which results in a target return temperature of 24.9 degrees
From my point of view, the temperatures will drop by about 1 degree everywhere. Probably less on the upper floor than on the ground floor because it is open upwards.
But 22.9 would still be too high on the ground floor, so my question is, I would only have to add the flow rate liters/min depending on the length of the heating circuit that is too much on the ground floor to the upper floor, right?
Also, I want to extend the heating cycles! Have I maybe already initiated this with the lowering of the heating curve?
