Electric UFH is just a big electric resistance heater, and unsurprisingly

We've got it installed in our (downstairs) bathroom. It's not the main
heat - it's got a towel-rail-come-radiator - and it's only on for an
hour or two in the morning.

Which means we have warm feet getting out of the shower

I don't think I'd want to do the whole house like that though.
