for traditional electric heating systems, including
Quantum, storage heaters and panel heaters.
For traditional electric heating the preferred
options for living and dining rooms are Quantum
orTSRACWcombinationstorageheaters.
Knowingtheoorarea,thewallconstruction
and the number of outside walls, the heater
loading in kilowatts is indicated in the
appropriate table. 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.
