I didn't say it would! I was simply saying that when comparing gravity with
pumped HW - using *any* boiler - the boiler will have to run for less time
for pumped, resulting in less wasted heat.

To a certain - but lesser - extent this is also true when comparing a fast
recovery with normal recovery cylinder (both fully pumped in this case).
