DUCTING RATING GUIDE
General Tips on Heating Air Ducting and Component Ratings

A heater has the biggest heating air throughput when it can operate with the air blowing freely. Heating air ducting components
reduce the throughput. To enable you to check whether or not the installation you plan reduces the air throughput to an
inadmissable degree, we have calculated a heater rating for each heater and a component rating for each heating air ducting
component:
0 = no temperature increase
- = no component rating
The sum of component ratings for the heating air ducting components must not exceed the heater rating, otherwise the outlet
temperature will become too high and trigger the safety cutout switch. If the sum of the component ratings exceeds the heater
rating, it can be reduced by selecting a larger diameter for the air ducting parts.
Rule of Thumb:
Double the cross-section or two identical components running parallel = 1/4 of the rating.
Example:
50 diameter hose
A = 19.6 cm2, R rating 1.0
The component rating of smooth welded pipes is only half that of flexible pipe of
75 diameter hose
equal diameter (e.g. double the pipe length).
A = 44.2 cm2, R rating 0.25
2-duct means:

Main-line Drawing for 1-duct and 2-duct Heating Air System

1-duct means:
A heating duct leads to or from heater. The
component ratings under “1-duct” are valid.

1-duct

2-duct

The heating air line branches into
two ducts after the heater. Up to the
branch the component ratings under
“1-duct” are valid, after the branch
they fall under “2-duct”. If an
adjustable outlet is used in the
2-duct heating system, one duct
must be unclosable. Note: When
determining the sum of the component ratings, do not take the closable
duct into consideration.
