top vs bottom inlet

All the sales material says a bottom inlet water heater saves money. But I thought a top inlet transfers the cold to the bottom through a dip pipe anyway.
So, what's the difference?

Secondly, I know you can't connect pex to the top but can you connect it directly to a bottom inlet?

I think Furd is right.

I am more of a copper pipe guy, but from what I have read you are right, you shouldn't run pex pipe to the top of a water heater. That being said, I have seen gas water heaters with pex pipe run right to the top connections of the heater.

Can you run pex into the bottom directly... For a bottom inlet

I cannot think of a single reason why not. The only bottom feed water heaters I have seen were for mobile homes, but I cannot say there may not be some others out there.
