To provide proper heating it is essential to calculate the
heat input necessary. This may be carried out professionally
by summing up the total heat losses for the various surfaces
and for the number of air changes however the following rule
of thumb methods give reasonable results:-
Radiant Panel Heaters
Take 160 watts per square metre of standard conservatory size.
Example:
Size of conservatory = 20 m2
20 m2 x 160 w/ m2 = 3200 watts
Total heat requirement = 3.2 Kw
Convection Heaters
Take 200 watts per square metre of standard conservatory size.
Example:
Size of conservatory = 20 m2
20 m2 x 200 w/ m2 = 4000 watts
Total heat requirement = 4 Kw
Infra Red Heaters
Take 160 watts per square metre of standard conservatory size.
Example:
Size of conservatory = 20 m2
20 m2 x 160 w/ m2 = 3200 watts
Total heat requirement = 3.2 Kw
Oil Filled Heaters
Take 200 watts per square metre of standard conservatory size.
Example:
Size of conservatory = 20 m2
20 m2 x 200 w/ m2 = 4000 watts
Total heat requirement = 4 Kw
The above methods are for normal domestic use and are only
approximate, for other conditions or for rooms with different
construction materials, please contact our Sales Department.
After calculating the total input required it will be necessary
to provide this in the form of one, two or more individual
heaters depending upon the shape of the conservatory e.g.
an 'L' shaped room would be better heated with heaters on
each 'leg' of the 'L'.
Location of furniture may also influence the number of heaters
required.
