Gas boiler, Eco or Comfort hot water setting

Good morning everyone,

I have a question about hot water preparation.
The following situation: I live alone in the house, my 8-year-old son is with me every 2nd week.
Now I wonder whether I should set the hot water preparation to Eco or Comfort mode and if my settings for hot water and circulation are okay?

Mon-Fri
Hot water between 6-7 and 16-18.
Sat-Sun
Hot water between 7-8:30, 11-12, and 17-18.

Circulation:
Mon-Fri --> 6-7:30 and 16-18:30
Sat-Sun --> 7:30-9, 11-12:30, and 17-18:30
Switching frequency 4/h

Hot water: 51°C and 20k flow increase, the boiler then heats up to about 60°C

Is this okay from your point of view?

Someone else told me to set it to Eco and hot water 24/7, which would apparently use less energy and reduce Legionella growth. Somehow it's not easy at all to know the right way now?

Thanks and best regards
Micha

How do Eco and Comfort differ?

In the turn-on hysteresis, 5K or 10K until reloaded.
