Timber supports for
hot water heaters
as per SANS 10254
We have been receiving queries regarding the timber
supports of the geyser drip tray and what the standard
requirement for a 114 × 50mm timber support is.
By IOPSA
SANS 10254 B.2.1 Installation of drip tray:
The drip tray shall be installed and mounted in the
following manner:
a) It shall be placed on the tie beams, over a load-bearing
wall and be supported by timber that complies with at least
grade 5 of SANS 1783-2, and of size at least 114 x 50mm,
spaced not more than 500mm apart and that complies with
at the IOPSA practical guide Installation Standards for
Electric Geysers in South Africa (page 22), it states that
a 120 × 30mm or bigger timber must be used at
500mm spacings.
So, what do we do now as plumbers to ensure our
installation complies to the standards?
This has caused major confusion and has a cost
implication that is not covered by most plumbers. The
required timber of 114 × 50mm is not a standard, off the
shelf timber product and this will mean that you will need
to increase the timber size to at least 225 × 50mm. This
cost is almost double that of a standard 114 × 38mm
timber that is currently used by most plumbers. Looking IOPSA would like to advise its members to take
the following measures when installing the drip
tray supports:
1. The tray should be placed on a timber that
complies with at least grade 5 of SANS 1783-2,
and of size at least 114 × 38mm, spaced not
more than 500mm apart.
