Having had a cistern for 20+ years and water pump for the house I really like the analogy to a water pump in a well! Helps me wrap my head around it much better.
Now I'm thinking (guessing?) as long as the H/W tank water doesn't drain backwards through the water pump there should always be water in the H/W tank as long as you don't drain it yourself? I'm assuming there is some sort of check valve to prevent that?
