3. Appliance description
This appliance is designed to store electrically generated heat. The
electrical heat is generated when the power supply utility enables
the supply of cheaper off-peak power.
The times when this supply is enabled depend on the relevant
power supply utility. The times when it is enabled are predomi-
nantly at night.
Subject to the required room temperature, the stored heat is
transferred to the room as hot air via a fan, and partially via the
appliance surface.
