If the contents of a pipe is allowed to crystallise and freeze this can cause the pipework to burst, leading to considerable damage, disruption and expanse.
Thermal insulation alone cannot fully protect pipes from freezing. 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.
Typically in pipe frost protection, an air sensing trace heating thermostat is used to sense the ambient air temperature. This energises the freeze protection heating cable when the temperature gets below a set point - usually around +3°C to +5°C.
