When considering the correct replacement
foracombinationstorageheater,thefrequency
with which the convector component is
used should be taken into consideration
(i.e. if it is used often, the heater may
already be undersized). Therefore it is
recommended that combination storage
heaters are replaced with a larger size
ofEco-Responseradiator,toensurethere
is sufficient capacity within the system
to match the capability of the convector
heater being replaced. In the case
of a 24kW combination storage heater,
it is recommended that an additional

Eco-Response radiator sizing – first time installations
The following chart provides guidance on
radiator sizing for first time installations
inkeylivingareasforexistingbuildings.
Simply select the floor area of your room
from the left hand column, and choose the
correct number of outside walls from either
the cavity or insulated cavity wall columns.
These tables do not take into account
particularly old properties or those built
very recently. If your property fits into one
of these classifications, please complete
the form on page 50 so that we can provide
a more accurate assessment.
Note: A ceiling height of 2.4m and a minimum of 75mm of roof insulation is assumed.
