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...

@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...
