Spot heating principle
In most outdoor or difficult
-
to
-
heat indoor applications, there are 2 methods when looking at the quantity of heaters required.
Option 1
is to comfort heat the entire area based on the total dimensions of the space, regardless of whether the entire area is
being fully occupied or not.
Option 2
is to spot heat the high use areas, such as over outdoor tables, BBQ
’
s, lounges, assembly lines or indoor work-
stations.
Often it is more practical and efficient to spot heat these areas. Spot heating will help to reduce the initial capital cost, as well
as the on
-
going running costs. Spot heating will allow the area to be
“
zoned
”,
meaning heating only the areas that are being
used, such as tables in a restaurant or outdoor alfresco area.
