I don’t fully understand the question, but for the bathroom there is a heat loss of 912 watts, which means that out of the required 1,612 watts only 700 come from the underfloor heating. The rest is coming from elsewhere ==> you need to tell us which electric heaters are installed on the walls.
It’s completely unclear how such a design can be made when different pipe spacing options are possible. You have 100 mm (4 inches) spacing everywhere. In the bathroom, 75 mm (3 inches) or even better 50 mm (2 inches) would have been an option.
Also hard to understand the choice of a 35/28 °C (95/82 °F) system. Why such a high temperature with such a large temperature difference? Well, in the bathroom there is also a partial wall heating, and the layout is a bit tighter. But clearly the design needs *optimization*.

Can you zoom in on one heating cycle? It looks like you have a return flow spike immediately after the heating cycle starts.Sure, I have resolved it a bit differently this time.Zaba12 schrieb:
The breaks are really way too short for such a long runtime.
What causes the return temperature to drop so quickly? I would say the -3 degrees Celsius (27°F) outside temperature 🙂. But since you have that too, it wouldn’t be an explanation.
