A gander at the rating plate should tell him all he needs to know
(notably, the maximum power rating and the nominal voltage - typically
since harmonisation, 230v). In some cases, the label may even show a
second higher wattage rating for 240v. In any case, since the heating
elements are a fixed resistance value, it's a fairly trivial task to
calculate the 240v loading from the 230v figures if more precision is
needed.

Quite allot of stuff specced for the UK market will quote the power
assuming its running on the genuinely manly 240V rather than the nominal
girly 230 euro volts.

So 2kW @ 240V suggests a load of about 29 ohms. So the actual power
could be anything from 1608W to 2207W if you swing across the full
permitted nominal 230V range of 216V to 253V
