Hello,
this is the first winter in my newly built house,
so I am starting to optimize the heating system.
I have installed the Buderus Logaplus package W22
GB172-14, G20, WU160W, RC300 package with an outdoor temperature sensor.
The house is completely equipped with underfloor heating with 10cm (4 inches) pipe spacing, triple-glazed windows, exterior walls consisting of 24cm (9.5 inches) Poroton bricks plus 16cm (6 inches) external thermal insulation composite system (ETICS).
Now my question is how to best set up the heating system, unfortunately I did not receive any instruction from my heating engineer.
Let me first give you some data.
Maximum flow temperature: 50°C (122°F)
Heating setpoint: 22°C (72°F)
Lowering temperature: heating off
Summer mode from 13°C (55°F)
Domestic hot water: 55°C (131°F)
Circulation pump switching frequency: 3/hour
Burner starts: 5247 (since mid-February)
Burner runtime: 2387 hours (since mid-February)
Service menu:
Menu 1:
1.7d. 0: no external flow temperature sensor connected
Menu 2:
2.1A: 14 kW
2.1B: 15 kW
2.1C: 2: Constant pressure 200 mbar
2.1E: 4: Intelligent heating pump shutdown...
2.1F: 0: Heating pump and 3-way valve (internal)
2.3b: Time interval between burner switch-off and switch-on 10 minutes
2.3C: Temperature interval for burner switch-off and switch-on 6 K
2.3F: Hot water keep-warm duration 1 minute
2.9F: Heating pump post-run time 3 minutes
2.CE: Number of starts of circulation pump 3 min on, 17 min off
Menu 3:
3.1A: 14 kW maximum heating output
3.1B: 15 kW maximum domestic hot water output
3.2b: 50°C (122°F) maximum flow temperature
3.3d: 3.2 kW minimum nominal heat output
These are the details I know, I hope I didn’t overwhelm you too much.
I would appreciate any advice.
Thank you very much

It doesn’t really make much sense, but if it helps you sleep better at night, then you can lower the temperature overnight.
I’m thinking of the idea that a night setback is programmed. Because ideally, heating should be done efficiently at night so that the bathroom is warm in the morning when you get up.

For me, it doesn’t help at all since I have to get up at 5 a.m. Then I would have to start heating again by 3 a.m. at the latest to get a comfortable indoor climate back. I would have to lower the temperature starting at 8 or 9 a.m. – I’m not sure if that’s really a good solution.
You have to try it yourself... but I would say that lowering the temperature setpoint (whenever) doesn’t really make a difference... maybe a small saving in the low single-digit percentage range... but it’s not really worth the effort.
My ground source heat pump has been running in automatic mode (outdoor temperature-controlled) for about 5 years without any setpoint reductions... and the house is always comfortably warm with reasonable energy consumption.

I have now set all the room thermostats to 30°C (86°F) so that the heating system controls everything completely.
The level is set to 19°C (66°F), the starting point to 20°C (68°F), and the end point to 36°C (97°F).
Currently, I have a flow temperature of 28°C (82°F), and the rooms seem to be warming up very well.
I plan to observe this for a few days initially.
