Step 1: Review the buildingStep 1: Review the building

• What are the insulation values (R-values) of walls and ceiling?

• Where are the windows and doors located?

• What is the building height?

• Is the roof pitched, flat or round?

• Are there any cranes? Height of crane rails? Would heaters go above or below?

• Are there any exhaust fans? What is the cfm?

• Do any exhaust fans run all the time? Or only selected times?

• Are there makeup air units? What's their capacity?

• Is there storage racking? Where is it located? Will it interfere with installation or

impact performance of the heater?

Heat Loss FactorsHeat Loss Factors

• R-Value: The thermal resistance of a barrier system. The R-value is the reciprocal of the

U-value. The higher the R value, the less heat is transmitted throughout the material.

• U-Value: A measure of air-to-heat transmission (loss or gain) due to the thermal

conductance and the difference in indoor and outdoor temperatures. As the U-value

decreases, so does the amount of heat that is transferred through the material. The lower

the U-value, the more restrictive the material is to heat transfer. Reciprocal of R-value.

• Degree Days: A unit of measure expressed as Heating Degree Days (HDD) and/or

Cooling Degree Days (CDD). Derived from the variance between the average temperature

during a given time period (month, season, year) and a reference point, usually 65oF. (definition courtesy Silicon Valley Power)

Step 4: Choose the heater sizeStep 4: Choose the heater size

• Determine the hanging height of the heater

– Generally the higher the hanging height, the larger the burner you can use. For example, a

25ft ceiling could have a 220MBH heater, whereas a 16ft ceiling would only use a 100MBH.

Larger may be too intense.

– Cranes could affect heater choice. If you can hang them above the crane the normal rules

apply; but if you have to hang them below the rails then you must adjust the height for

comfort.

– Consider the location of work stations and people movement through those areas. A large

heater above a work station might overexpose occupants to heat. However, if people are

constantly moving in and out of the work station, a larger heater may be suitable.

• Loading Docks:

Loading docks should

have slightly more

heat than the normal

load because of wind

and door openings.

sudden cold.

Special SituationsSpecial Situations

• Exterior Applications:

Outdoor patios, golf

driving ranges, porticos

and driveway de-icing are

best done with R-Series

Heaters. Heaters are

generally placed closer to

the ground to get more

direct radiant effect.

HOME STEP 1 STEP 2 STEP 3 STEP 4 STEP 5

Special SituationsSpecial Situations

• Car Wash: The environment

in a car wash can be very

corrosive. Water absorbs

infrared much more than air

so more input of heat is

needed. The UXR Heater is

available with stainless steel

options, including tube,

coupler and hardware. This

will stand up to a severe

environment much better

then a standard UXR.

L-Series is designed for low ceiling

applications where more even

radiant output is desired. Long

hallways, covered patios and

animal confinement are good

applications.

Premier-VS Vacuum SystemsPremier-VS Vacuum Systems

• This award-winning system is suitable for many

applications, especially:

– Buildings with work stations where people operate in

one place (i.e. packaging areas, assembly lines or

airport baggage areas).

– Large canvas structures where minimum vent

penetration is allowed. Side wall venting is preferred

with canvas roofs. This type of structure requires a lot

of heat as well.

– Underground garages and in-between floors where

venting through the roof is impossible.

– Facilities where the design / owner requires

centralized controls

– Facilities where the design / owner requests variable

heater rates

– Vacuum system safety control

High Intensity HeatersHigh Intensity Heaters

• High intensity heaters naturally vent into the building space. Always remember to:

– Allow for mechanical ventilation.

– Take mechanical ventilators into account in your heat loss calculation.

• High intensity heaters are used primarily for spot heating because:

– A large degree of heat can be focused on a smaller area.

– They are very effective for small work stations in large, drafty buildings or by overhead doors.

Common Misconception: Very high ceilings require user to choose high

intensity over low intensity. Low intensity radiant does not get to the floor.

In fact, both send the same amount of energy to the floor. High intensity

is concentrated so you feel it more than the tube heater which spreads it

down the tube. Also you can see the high intensity working with the

reddish glow where the tube heater has no glow at all.

Step 5: The layoutStep 5: The layout

• A fundamental concept:

– Low intensity heaters are hotter at the burner end (900oF – 1,000oF ) than

the flue end (400oF to 500oF)

• Therefore, for best comfort and where suitable:

– Place heater head to tail

– Use U configuration

– Place the “hot end” over the “cold spots” (i.e. at doors, or near cold walls)

HOME STEP 1 STEP 2 STEP 3 STEP 4 STEP 5

Perimeter HeatingPerimeter Heating

• When buildings have large

areas relative to heat loss,

a perimeter layout may be

preferred. Put heat over

the greatest heat loss area

(i.e. exterior walls, doors,

windows and loading

docks). Place the heaters

parallel to walls and

doors, approximately the

same distance away from

the walls as the hanging

height.

Use of side shieldsUse of side shields

• Use of side shields are recommended:

– Where heaters have to be placed

closer to the wall than their hanging

height or shelves allow.

– Along walls where wall hanging

brackets are used, such as patios.

– In hockey arenas to reflect the heat

back to the people, not at the ice.

45 degree angle Side shields

Side shields reflect at least 15%

more infrared energy to the floor

compared to tilting the shield at

a 45o angle.Did

Common VentingCommon Venting

• Definition: When more than one

heater is vented through a

“common stack”, whether that

stack vents through the roof or

through the wall.

• Sizing of the vents is governed

by local gas installation codes

• Always one thermostat per

stack

• Generally, design for a

maximum of two heaters per

sidewall vent and a maximum of

four heaters for rooftop venting.

HOME STEP 1 STEP 2 STEP 3 STEP 4 STEP 5

Thermostat placementThermostat placement

• When you are locating the thermostat, consider the following

recommendations:

– Locate thermostats to minimize the impact of outdoor temperature on the

thermostat reading—preferably on an interior wall.

– Do not place thermostats in direct line of infrared heat.

– Keep thermostats away from direct sunlight, drafts or machinery that could

change the temperature readings.

– Hang approximately 5ft off the floor.

• Line voltage thermostats can have a maximum of 10 units.

• Low voltage thermostats can have a maximum of 6 units in combination

with a CE115 Relay.
