Optimisation
A heat pump's efficiency depends directly on how large a temperature difference it has to produce. The lower the flow temperature, the higher the estimated COP.
28–35 °C for underfloor heating, typically 40–48 °C with radiators on a cold day. If your system consistently needs over 50 °C, the cause is usually heating surface area or balancing.
Lower by 1 °C at a time and observe. Before lowering further, make sure every room gets flow and thermostats aren't fully closed.
Not necessarily. If the heating surface is sufficient, the same amount of heat reaches the house at a lower temperature, just over a longer running time.
Most heat pumps show it on the control panel. If needed, it can be measured with a surface sensor on the pipe.
