Thorne & Derrick are the UK’s Largest Stockist & Supplier of Heat Tracing Systems for electrical heating of pipework, tanks, drums and vessels in both industrial and hazardous area locations with potentially explosive atmospheres, Zone 1 & 2 (Gas), Zone 21 & 22 (Dust).

Since 1985 we have been providing expert technical support, competitive prices and an international delivery service for leading manufacturers of heat tracing cables including ATEX Trace Heating from Chromalox, EasyHeat, Eltherm and Nelson.

Our Team of Trained Sales Engineers are available to advise and support your heat tracing applications – this includes design and supply of complex multi-kilometre, major-project systems to custom heat tracing cable kits for the Winterisation of plant and factory facilities.

Customised Heat Tracing Cable Kits

Each kit can be supplied ready to install with step-by-step instructions – simply attach the heat tracing cable linearly to the length of the water pipe, insulate and plug in to the mains supply. Controlled by an air sensing thermostat that will activate when the ambient temperature falls below 5° Celsius the pipe heating cables will gently trace heat the pipe, thus preventing water from freezing – our friendly and expert team of Sales Engineers or just a call away if you’re in doubt.

Thorne & Derrick specialise in providing specialist heating for industrial and hazardous areas including Eltherm’s heat tracing cables and heated hoses.

Self-regulating Heat Tracing Cable System For Hazardous Areas

Self-regulating Heat Tracing Cable System For Hazardous Areas


Precise, Medium & High Temperature Pipe Heating

  • Precision temperature control and pipework heating for anti-icing, fuel oils, paints and fertilizers
  • Medium temperature range pipe heating cables for polymers, acids, heavy fuels and chemicals
  • High temperature pipework heating including heavy oils, asphalt, sulphur and bitumen

Industrial heat tracing cables withstand steam cleaning processes and high process temperatures in the oil, gas and petrochemical industries. Typical industrial heat tracing applications includes caustic soda, chocolate, syrups, waxes, cooling and safety showers.


Heat Tracing Cables | Technologies


We supply tracing cables to optimise, protect and provide industrial process heating across all sectors including utilities, oil, gas, petrochemical, pharmaceutical, data centre, renewable energy, food/beverage and manufacturing facilities.

➡ Self Regulating these types of heating cables frost protect pipes and maintain critical industrial process temperatures.

The heating cable consists of 2 parallel conductors embedded in a heating core manufactured from conductive polymer – the core of the heat tracing cable is radiation-cross-linked to ensure long-term reliability.

Heat is generated as electric current passes through the conductive polymer core between the cable’s conductors. As the ambient temperature drops, the number of electrical paths through the heat trace cable core increases and more electrical heat is intelligently produced. Conversely, as the temperature rises, the core has fewer electrical paths and less heat is produced.


 ➡ Constant Wattage – constant power heating cables are a parallel resistance cut-to-length heating cable delivering the same power output irrespective of pipe temperature, 110V & 240V options.


 ➡ Mineral Insulated with extreme heating temperature capabilities (> 350 °C) and exposure limits (> 500 °C) MI cables are the most durable electric heat trace cable with high impact, fire and temperature resistance. Specified when the heat tracing application temperature and power output requirements exceed the operational and circuit length capabilities of our ranges of self-regulating and constant wattage heat trace cables.

Heat Tracing Cables | Types


Trace heating cables provide freeze protection and temperature maintenance (or heating) to pipes – commonly referred to as electric heat tracing, surface heating or heat tracing cables they are used to protect mechanical services (pipes, vessels, tanks, hoppers, valves, drums) against cold weather damage by sub-zero temperatures and frost conditions.
