run out of hot water etc without needing to duplicate
the heating elements as you do currently.

That's how the systems that already have smart meters do it.

How?

I already run my dishwasher, tumble drier and washing machine in the
small hours. How will a smart meter help me do that?

Why can't the supplier simply tell me (or the appliance) directly
over the internet? How does a smart meter help?
