The idea is that the alloy has no heat capacity at all and transfers
all the energy given to it immediately. That resulting in fast results
and no losses.

With any electric heating system there will be no losses. The size of
the heating wire is negligible compared to the thermal mass of the
building (even a "slow" wire based system will be up to temperature in
seconds, the house is at best going to take tens of mins to respond). So
basically you can ignore all the marketing bull and get back to first
principles.

If you house needs an average constant input of 5kW of energy to keep
warm, then that is what it takes - the source makes no real difference.
The cost of running any electrical system[1] that does that will be much
the same.

[1] Someone did mention heat pumps, which will recover heat from outside
and pump it in, giving and effective rate that exceeds the amount of
electricity consumed.

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.

This is more the key - good insulation will reduce heat loss
grammatically. The same percentage savings would again be archived with
any heating system though.

Just adding what I have heard from the distributor and read from
marketing docs. No real experience with the material.

Apply some logic and you will see you have electric UFH. If that is your
only source of heat it is likely to be pricey to run. Also look at the
power requirements - you are talking about lots of floor area - have you
worked out the power consumption for the house with it all running?

Have you done any heat loss calculations for the house? If not google
back on this group for some information. That needs to be the first step
so that you know what level of heating you are going to need.
