Indoor Spot
and Zone Comfort Heating
Spot heating locates the heater above the areas
you are located so the air in the entire room is not heated. Infrared heats
objects not air, so you are kept warmer even in a relatively cold room. Some
heaters use a quartz glass heating element and some use a metal sheath tubular
element. Metal and Panel heaters last longer, do not emit light, and are not as subject to
damage from environmental factors, shock and impact. The advantage of quartz is
quick heat up (seconds) and a higher efficiency of infrared.

An Indoor Spot
Heating Design will maintain an isolated comfort level within
a larger and cooler area. The ambient temperature of the surrounding
areas must be considered to help determine proper input to the work
area, but will not in turn be affected by the isolated heated area. Many
times a series of spot heat areas can be incorporated within the total
area to avoid maintaining a higher ambient temperature throughout the
building.
Comfort levels
will depend on the intensity of the wattage delivered. Wattage should be
sufficient to balance normal body heat losses, and will depend on
ambient conditions, dress, and activity of the individuals in the work
area.
Since actual ambient
temperatures are not maintained, several factors involved with
indoor spot heating must be considered:
1) Beam patterns should
always cross approximately 5’ above floor level to provide even heat
at the work area.
2) Avoid installing only one fixture directly over
a person’s head at a work station.
3) All spot heat
applications, regardless of area size, should heat the person
or object from two sides.
4) Fixtures
should be mounted so that the long dimension of the heat pattern is
parallel to long dimensions of the area to be heated.
5) Spot heating systems can
be controlled manually, or preferably, with a thermostat located away
from the direct pattern of the heaters. Percentage timers may be used,
but are not as effective.
6) Avoid
mounting fixtures at heights less than 8’.
The Estimator
must also have the following specific information available before
calculating the heating load and fixture layout:
1) Design voltage and phase to be employed.
2) Minimum practical mounting height for the
heating equipment.
3) Specific dimensions of the area to be heated.
4) Specific statement of the heating task
including the design temperature required.
|
Calculation Method for Indoor
Spot Heat
1) If there is no heat in the
building, determine the lowest potential outside design temperature and add 15
degrees to arrive at the lowest inside temperature.
2) Determine the desired temperature to be maintained
at the work area.
3) Subtract (1) from (2) to find the change in
temperature level required or temperature rise.
4) Find (3) above
(or the closest number to
it) in Column 1 of Table 1. Select the "watts
per square foot required" for the type of building and appropriate fixture
mounting height.
5) Multiply (4) above by the total square feet of the
area to be heated. This determines the total watts required.
