Does nobody over run the pump anymore?

Until the rads go cold?

That wasn't quite the point I was making, just that "If the boiler is
off there's no point in the pump running" is not entirely accurate, pump
overrun can help the system extract heat from the boiler that would
otherwise be wasted. Something in the back of my mind tells me it's
kinder to boilers as well but that may not be true.
