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.
