Dimplex Quantum
Heater sizing guide
Dimplex provides a number of options,
to meet different property and timescale
requirements. If you need to obtain an
indication of the heating requirements for
estimating or if you need heating for one or
two rooms, please use this Selection Guide.
Alternatively use our online calculator
at www.dimplex.co.uk/heatdesign
For single properties, please complete
the form on our website (also at
www.dimplex.co.uk/heatdesign)
and send it with a sketch plan to
our heating design department.
We aim to provide an accurate
assessment within 7 working days.
For multiple properties, please send us
comprehensive scale drawings (scale
1:50 or 1:100) together with construction
details and any other relevant information.
We offer a 14 working day service for
this type of assessment.

The tables below provide heater sizing
guidance for Quantum heaters. Knowing
the floor 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 our website so that we can
provide a more accurate assessment.
