Are you absolutely certain about this?

Yes.

I've never seen a device intended
for this sort of use. FCUs are limited to 13 amps. Indeed it's now frowned
upon to connect any sustained fixed load - like say an immersion - to a
ring circuit, even within the 13 amp limit.

Not saying it's a good idea, but it's allowed, with a fuse
or breaker up to 16A.

Connecting the primary electric heating system (space or water)
to a ring is not allowed though. Supplementary heating and
small water heaters are allowed.
