Does anyone have a rough idea of how many kw a large storage heater is
set on number 5.

The biggest normal domestic storage heater is 3.4 kW (giving 24 kWh
'charge' in 7 hours).

The 'setting' (input charge control) is just an on-off thermostat, and
doesn't affect the power consumption, except in the sense that the
latter will be either zero or 3.4 kW.

Please can you clarify as I've never owned, let alone inspected, one of
these at close quarters.

Are you saying storage heaters stay on at full power for the 7 hour
daily Economy 7switch on. Then the stored heat is released at a rate
effectively determined by the dial thermostat?
