Installation in gutters
and downpipes
Preliminary proceedings:
• measure the length of gutters and downpipes,
• assess the required heat output resulting from
the climate conditions in which the installation is
to be made,
• select the proper length of the heating cable
taking into account the number of the cable’s
segments in the gutter and downpipe.
* if the building is located in the regions of intense
snowfall
The values are given for gutters of diameters Ø100-
125 mm.
Note:
If the water from downpipes is discharged directly
to the rain channel, the segment of the downpipe
from the surface level to the soil freezing depth
also should be heated.
If the calculated heating cable length has no direct
equivalent in the available ready-made units, select
the longer cable and leave excess cable in the pipe.
