How long is a piece of string?

Have a look at the specification of it, which will be detailed somewhere on
the unit, usually near the mains input.

At the risk of being accused of hi-jacking this thread, is Economy 7 (or
a lower tarif nighttime rate still available for new customers?

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?

You have two controls. One the input charge controls how hot the bricks get
during the E7 period, the other controls a flap that lets the heat out.

Storage heaters normaly have two controls "input" and "output". Both are
thermostatic devices.

The input one controls how hot the bricks are made in the off peak
period. The hotter you make the bricks the more heat is stored and the
longer it takes to heat them up.

The output control is a nominal room thermostat that opens/closes a flap
that controls how much air convects through the bricks and thus how much
heat is released into the room.

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.

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
