The pump reacts, it doesn't decide

It's got the power, it's the thing that's moving, it feels like it's in control.
But it doesn't decide anything. It just reacts to whatever the system design hands it.
Cold radiators aren't usually a pump problem, they're a design problem the pump is quietly struggling with.
Once you stop looking at the pump first, everything else starts making more sense.
Resistance, flow rate, ΔT, pipe sizing, they're not separate facts to learn one at a time.
They're one connected system and the pump is just the last thing in the chain reacting to what happened everywhere else.
