Hi,

I would like to learn how the water flows in a hot water heater. Is
there a description somewhere on the web. I'm thinking of an old
fashioned cast iron radiator or a modern runtal, such as this one:

I'm basically puzzled how the water enters on the bottom left, leaves
on the bottom right and at the same is able to reach the top.

It's heat transfer and not irrigation. The water will give up it's
heat wherever it can.
