I should say it is. It’s well beyond the rating for a typical household
outlet.
 No, it's exactly the limit of a UK 13A socket (assuming the nominal 230V, in practice most will be above 240V) but they do tend to suffer when used with long running at full load (poor contact -> high resistance -> heating -> charring -> fire)
 
Whatever it is, I imagine you’re going to need professional
electrician help to set it up.
 I wouldn't trust a smart switch on a long-term load such as an immersion heater, there are 20A versions, I think I'd prefer using a smart switch to drive a chunkier contactor and hardwired terminals.
 
Well I have yet to code up my board that has a simple 20A relay.
I'd probably use a GTO thyristor with an opto-coupler than a contactor. It's cheaper
