Yes & no.

Very long time ago, when we wanted to install a water heater, the electrician tap from 1 of the lesser use power socket (13A) at the room next door. Controlled by a 20A switch.

So far 28 years, I'm still surviving.

The othet suggestion I have which are cheaper and do not require major rework would be changing the socket to the WH type 15A at least, and before the switch just install a dedicated RCCB 10ma  before your 20A switch which should give you a good protection already.

The old Thai houses wired the WH using a single RCCB usually planted next to or on top of the WH.
