ELEKTRA VCDR
Heating Cables
Stage 1
Installation in gutters
and downpipes
Preliminary proceedings:
• measure the length of gutters and down-
pipes,
• 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.
Heating cable fixing in gutters and downpipes
Heating cables should be fixed in order to main -
tain steady spacing between neighbouring ca-
ble’s segments. The segments must not touch or
cross.
Gutters
Heating pipes can be fixed with holders (holder
spacing should not exceed 30 cm) or a wire with
clips.
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 lead excess
cable in the pipe.
