So my delta t on the Mitsubishi 6kW Ecodan Heat Pump is usually around the 3c. AI Gemini suggested that the pump speed was too fast, so I've bumped this down from 3 to 2. The current flow temp is 45c (for 2.5 hours), we're 1c off room temp target. Lets see if we get a change.

@ pump speed 3, 23w, 17L/min = ~3.5c @ pump speed 2, 18w, 15L/min = 3.5 - 4c @ pump speed 1, 13w, 13L/min = 4.5 - 5c

lol, IGNORE THESE FIGURES, the kitchen UFH was off!!

I thought the ufh actuators were NO, but they're NC

I suppose this info could be useful at some point
