The power distribution system of an Inditherm under-grass heating
system will be designed to suit the unique needs of each particular golf course.
In general, there will be a central control room located in the main substation
feeding mains voltage to the control panels located around the course. These
will each house transformers and switchgear that will supply the heating systems
In general, there will be a central control panel located at the golf course
substation feeding mains voltage to transformer panels located at the greens and
tees. Where a green and tee are adjacent to one another, a single transformer
panel can be located to feed both heating systems. Transformer panels can be
mounted discreetly behind vegetation, so as to blend into the environment or
where they cannot be hidden can be mounted underground.
Although power may already be available at the greens and tees to power the
sprinkler system and provide lighting, it is unlikely that this will have been
designed to handle the current draw needed to run the Inditherm system. A full
analysis of the course will therefore be required by Inditherm to ensure that
the correct cable sizes are used. However, on new courses, the cables can be
sized to provide all the power requirements around the course.
The power consumption will depend upon a number of factors, including the
ambient temperature conditions, the heating pad spacing, and the way the control
system is managed (automatic or manual). However, a typical 18-hole golf course
is likely to be rated at between 400kW and 600kW if just the greens are heated
up to between 800kW and 1.2MW if the tees are heated as well.
