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.

Or until they are fully charged and the thermostat cuts
the input off. Unless you live in a very cold house they
don't discharge fully each day so they don't stay on for
the full 7 hours each night.

Then the stored heat is released at a rate
effectively determined by the dial thermostat?

The discharge is (partially) controlled by the output
dial, which moves a flap connected to a bimetalic
strip. However, most of the heat radiates through the
case and the flap only makes a small difference to the
rate of discharge
