The idea is that the alloy has no heat capacity at all

I knew there'd be magic somewhere in there.

and transfers
all the energy given to it immediately. That resulting in fast results
and no losses.

There are never any losses, all the heat generated by an element
*always* ends up in the surroundings.

They claim that in a well insulated house the real
consumption is only 20% of the time the heating is turned on. So if you
are running it for 10 hours a day, the consumption would only 2 hrs
worth.

I won't even pretend to understand that statement.

Also, the increased heat transfer area ensures more even heating.

This may be true, but it depends on what the heating element is
installed in.
