9.1 Project design considerations & guidelines

NOTE: All CIR Infrared Heaters must be installed on a
timer or timer switch.

NOTE: Refer to “9.5 Minimum required clearances”
on page 7 regarding the minimum required
clearances.

The size and quantity of heaters (amount of heat input) required
over an area to provide comfort is affected by the following factors:

9.1.1 General:

— Amount of air movement in the area: “wind chill” requires

additional heat input
—Provide wind breaks wherever possible
— “Spot heating” comfort is most effective if people are heated

from at least two sides
— Available mounting height for heaters at the project site

9.1.2 Indoor application:

— “Space heat” the entire structure (accurate heat loss

calculation required. For assistance contact Stiebel Eltron at

800-582-8423 or [e-mail]), or
— “Spot heat” only part of a cold indoor area

» Input formula = Site Length x Site Width x Temperature Rise x

Heat Density per Degree

Example:

— Outdoor patio: 30 feet long by 10 feet wide
— Desired temperature rise: 20°F (average over the area)
— 30 x 10 x 20 x 2 = 12,000 Watts total input required

Compare the values of the available mounting height and area
dimensions at the project site to the recommended mounting
heights, length and width of coverage area, and typical average
he at dis tribut ion in “9. 1 Pr oje ct design considerations & guidelines”
on page 6.

Layout:

— Space the heaters uniformly around the perimeter (and if

required, in the center or throughout the area) to provide
suffi cient heat density to accomplish the desired temperature
rise or spot heat only specifi c locations within the area.

— Provide heat from at least two sides wherever possible

NOTE: The design information presented here is
intended as a guideline. The accuracy of determining
or estimating all factors above will affect performance
and satisfaction. Air movement in particular will
affect comfort.

9.2 General installation instructions

NOTE: Read all instructions and plan the installation
before proceeding.

— The activity level of the people: seated at rest, hard physical

labor, etc.

9.1.3 Outdoor application:

NOTE: MODEL CIR 150-1 I IS FOR INDOOR USE ONLY!

— Any area heated outdoors is “spot heat”
— Models CIR 150-1 O, CIR 200-2 O, and CIR 400-2 O are for

indoor or outdoor use

» Desired temperature rise:

— In what seasons is comfort required and what is the outside

design temperature?
— Then what temperature rise is desired for comfort? (10°, 15°,

20°, 25°)

» Calculate the required input to get the desired average

temperature rise:

Input Required per Area per Degree Comfort Temperature Rise

Heat density
per degree F
W/(ft2)/°F

Outdoor heating
(up to 10 mph wind) 2 40
Indoor spot heating
(protected area, low
air movement) 0.75 14

Heat density
