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

So, at an outside temperature of 8°C (46°F), I have a supply temperature of 27°C (81°F), which results in an indoor temperature of at least 23°C (73°F) in the bathroom on the ground floor and a maximum temperature of about 24°C (75°F) in the bedroom. I think these are excellent values.
So, the guest bathroom is set to 20 degrees Celsius (68°F), just like the other rooms. The issue is probably that it is only 4 m² (43 sq ft) in size, and half of the room doesn’t have underfloor heating installed because of the floor-to-ceiling shower, or the window is drafty—one of these two must be the cause.
