When, where and why to install trace heating. A little information on the different heat trace applications and the different types of trace heating installation areas. For more information please visit www.eshltd.com

1. Basic Application &
Product Guide

2. Trace heating introduction…
Electric trace heating is the application of a compensating heat source used to temperature maintain or
raise pipes, surfaces and vessels.
Trace heating cable replaces the losses of heat from a surface to allow temperature maintenance of a
product, which thermal insulation alone can not maintain.
Trace heating can be used to protect pipes from freezing (Frost Protection), maintain the temperature of a
hot water system (Hot Water Temperature Maintenance), or maintain process temperatures for smooth and
efficient running of process plant equipment (Process Temperature Maintenance).
Heat trace systems can be categorised into four main installation areas:
• Domestic
• Commercial
• Industrial
• Hazardous

4. Frost Protection
Trace Heating
If the contents of a pipe are
allowed to crystallise and
freeze this can cause the
pipework to burst, leading
to considerable damage,
disruption and expense.
Thermal insulation reduces
the rate of heat loss but
does not eliminate it. In
order to minimise the
effects of heat loss, frost
protection trace heating is
used to supply a heat
source to replace this heat
loss and therefore maintain
the pipe temperature.

5. Hot Water Temperature
Maintenance
Today’s market is calling out for more cost efficient and environmentally friendly solutions. The
combination of hot water maintenance trace heating and the correct thermal insulation will:
 Reduce the amount of pipework required
 Reduce power consumption
 Reduce the amount of water wastage
 Ensure hot water at the point of use
 Allow for periodic purging of the system to protect against Legionella

6. Process Temperature
Maintenance
Many products need to
maintain a specified
temperature in order to
remain in a liquid state for
processing. This
temperature is usually far
above the temperature of
the surrounding air.
Trace heating cable is
vital in ensuring that
process temperatures of
pipes and vessels are
maintained to allow for
smooth and efficient
running of process plant
equipment.

14. Hazardous area trace
heating
A hazardous area location is
defined as a place where
concentrations of flammable
gases, vapors, or dust occur.
Electrical equipment that must be
installed in such locations are
specifically designed and tested
to ensure they do not initiate an
explosion, due to arcing contacts
or high surface temperatures.
