Why electric heating and not vapour heating?
Over the last few years a steady tendency of transition from steam heating to electric heating systems using heating cables has been established at Ukrainian enterprises. This is greatly influenced by the high prices and costs of the gas used. The cost-effectiveness is primarily due to the fact that in such a system only the heating cable is the heat-generating element. Losses in the supply of electrical energy to the heat satellite are minimised, in contrast to the steam heating system, where heat losses occur in the steam supply pipework, distribution combinations and condensate drainage pipework.
The cost-effectiveness of electric heating is primarily due to the fact that in such a system only the heating cable is the hot element. In this way, the energy supply losses to the heat sink are minimised. This is the main distinguishing feature over vapour heating systems, where both the steam supply piping, distribution combinations and condensate discharge piping are hot. Even with the best insulation, there are heat losses. The operating costs for electric heating are on average 2 to 5 times lower than for vapour heating for various companies.
There are also industrial cable heating systems where the savings are most significant today.
Industrial systems imply the use of special heating cables, which are able to generate high power and maintain pipeline temperatures of more than 100…200°C. Such systems are used mainly in hazardous areas, quite often at petrochemical, oil production, chemical industry facilities.
Industrial electric heating systems are widely used all over the world and have shown their efficiency and cost-effectiveness in comparison, for example, with the system of steam heating used in the last century and still used in many enterprises in Ukraine. For the last 4 years (since 2014) in Ukraine industrial enterprises have been switching to cable heating system. Maintenance costs for electric heating systems are almost 40 times lower than for vapour heating. At the same time, comparing the cost of energy carriers, it can be noted that the electric tank heating system is almost 3.7 times cheaper than the vapour heating system.

The cost-effectiveness of electric heating is primarily due to the fact that in such a system only the heating cable is the hot element. In this way, the energy supply losses to the heat sink are minimised. In contrast to the electric heating system, in a vapour heating system, the vapour supply pipe, the distribution combinations and the condensate drainage pipe are hot. Even with the best insulation, there are heat losses. Operating costs for electric heating are on average 5-7 times lower than for steam heating.
The steam heating system is difficult to control, which causes additional energy losses due to fluctuations in ambient temperature. Various control systems have been developed and are widely used for electric heat tracing: from a conventional thermostat to complete electric heat tracing control systems that allow monitoring process temperatures in hundreds of pipelines from a single computer.
Another important indicator of the efficiency of an electric heating system is the service life. Here electric heating also wins out over vapour heating. The service life of electric heating systems is at least 20 years, while the service life of vapour heating is usually less than 10 years. In addition, with electric heating, the service life of the thermal insulation is increased.
