Design Scenario

A tube heater system is being installed in 27.4m (L) x 15.2m (W) space with 4.3m ceilings. Two overhead
doors are located at one end and an equipment storage area exists on one side. The calculated heat load
is 110 kw.

•

Two burners (55 kw each) are
placed at one end, opposite
the area of highest demand
(overhead doors).

•

Recommended mounting
heights are not observed.

•

Produces an uneven heat
distribution.

•

Four burners (30 kw each)
are placed in each corner.
Burner (hotter) ends direct
heat to areas of highest heat
demand.

•

Recommended mounting
heights observed.

•

Distributes heat more evenly.
