The benefits of storage heating
One of the benefits of storage heaters is that after their
night-time intake of off-peak electricity i.e. the ‘charge’ they
will always emit some heat throughout the day and night.
This helps to maintain a steady temperature so that the room
never gets cold, because the whole fabric of the room retains
some warmth.
In the morning, when the core is at its hottest, the amount of
heat being transmitted is at its greatest and the heater feels
hot over most of its upper surfaces.
As the day progresses, heat is transmitted from the heater to
the room and the surface of the heater becomes less hot.
If the amount of emitted heat becomes insufficient the
output of the heater and thus the room temperature may be
increased by using the Output Control.
Know your heater
Off-peak electricity is supplied from the national grid to your
house, usually overnight, when national demand for electricity
is low. This is called the off-peak period.
Because it is off-peak it is supplied at a cheaper price than
normal day rate electricity and requires a separate off-peak
electrical circuit and meter. This circuit only operates the
storage heaters, and switches on automatically during the
off-peak time period which will occur at set times of the night
or day. If you are unsure which off-peak tariff you have, you
will need to contact your electricity supplier for clarification.
In the same way as you charge up a battery, electricity is used
to heat elements in your heater, which over a number of hours,
gradually transfer the heat to a very high density material that
absorbs and stores the heat for use during the next day. This
process is referred to as ‘charging’ the heater.
In order to ensure your room stays warm overnight, storage
heaters are designed to give out some heat even when the
heater is ‘charging’.
When the off-peak ‘charging’ period finishes the heat is
gradually released in a controlled way over the course of
the day.
Storage heating can be used to provide all of your room
heating or as background heating which can be easily
topped up with supplementary heating as required.
