I fear I am not explaining things very well. Let me try again. Let's start with a very simple imaginary scenario. Over a 24 hour period, the outside...
I had a similar experience, but the range was wider, some clearly far too high, others definitely too low. I don't think the 12.4kW figure is that far...
I already have an external power meter, the heat pump supply has its own meter. I know exactly what the heat pump input is, recorded on a weekly basis...
Wow, that is a lot. I have nine which at full whack can theoretically deliver 12.4kW. If the primary pump in your 12kW (which is very likely the sa...

I suppose that is plausible but it seems on the low side. Assuming building heat loss vs temp is linear, 12.4kW @ -2 / 0kW @ 20 degrees ambient, then ...
@derek-m - thanks for the figures. I knew the adjustment wasn't linear, useful to have a bit more precision. Given some of the lockshields only have m...
Interim update: the rads are approaching being balanced, its taking a while because it is so mild and the heat pump is not running for longish periods...
