The benefits of DuoHeat
The DuoHeat radiator is the latest in energy efficient heating.
With a slim modern design and user friendly electronic
controls DuoHeat is the perfect choice to provide efficient,
controllable heating.
Your DuoHeat radiator works by providing continuous warmth
from a carefully balanced combination of "stored" and
"radiant" heating. Some energy is taken in by the radiator
when electricity tariffs are low and this is supplemented
by top up from the low wattage element attached to the
front panel, to ensure the room temperature remains at
your preferred level throughout the day.
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 operates the storage
heaters and switches on automatically during the off-peak time
period which will occur at times of the night or day. If you are
unsure what off-peak tariff you have, you will need to contact
your electricity supplier.
In the same way as you charge up a battery, electricity is used
to heat elements in your heater, then over a number of hours,
the elements 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.
However in order to ensure your room stays warm overnight,
DuoHeat is designed to give out some heat even when the
heater is 'charging'.
The normal on-peak (or day rate) circuit supplies energy to
operate the low wattage radiant panel and the controls within
the heater, when needed for top-up heating.
