We warm the water supply. Heating cable for water supply: purpose, methods and installation options
It is easy for a beginner and not too experienced summer resident to make a serious mistake, which will lead to serious consequences. A failed crop, a rickety house, a greenhouse demolished by the wind, a collapsed well, these troubles will require large material costs, and most importantly, they will cause a serious psychological blow. The situation with defrosting the water supply system in winter also applies to such disasters, because putting the system in order in the future will require partial or complete replacement of the pipelines. And if the pipes are buried in the ground or laid under buildings? The scope of the repair work will be large, and the costs are quite substantial. It is necessary to take this into account and secure your water supply in advance from freezing. A great way will be discussed below.

What is a heating cable for water supply
How to save country water supply from freezing in cold weather? Draining water helps if the water supply is not in operation in winter. With regular use at any time of the year, you can insulate it along its entire length, but it is difficult to assess the temperature that will be on the street and in severe frosts this method may not help. It is much more practical to use an electric heating cable for water supply, which, due to its design, is able to ensure uniform heating of the pipeline and prevent freezing of water in it.
This is the most effective way to protect the pipeline from freezing today. The principle of operation of this device is laid in its name by heating, the cable transfers heat to nearby pipes, which at low ambient temperatures prevents the crystallization of water, which has been without movement for some time.
Types of heating cable
The heating cable consists of a copper wire protected by a special polymer coating, the composition of which does not affect the quality of drinking water. The cable is equipped with an electric plug for connecting to the network. According to its location, the heating cable for the water supply can be internal and external. If the pipe is buried in the ground or in contact with an aggressive environment, it would be more reasonable to use the cable inside the pipe, this will extend its service life and thereby reduce operating costs. If possible, it is more advisable to install a device that will itself turn on at critical temperatures. Using a self-regulating heating cable for a water supply system can significantly reduce the energy consumption of this process, because at a plus temperature, heating will not be performed.
Installing a heating cable
Contrary to stereotypes, the installation of a heating cable for a water supply system is not a complicated procedure and does not require special tools and skills. In the set of all purchased products are sets of necessary components for terminating and connecting cable parts both among themselves and with power wires. There is definitely a heating cable instruction, which describes the process of assembly and installation of the system. In the locations of shutoff valves during outdoor installation, the cable is wound on the pipe more often.
When installing a heating cable for a water pipe outside (or inside) a metal pipe, grounding is necessary.
Heating Cable Manufacturers
The most famous and widely represented on the Russian market is the heating cable for the Ensto water supply system, which is offered in various modifications and in different sizes (from 2 to 20 meters long), including one sold in footage.
A more economical option, however, of the same quality, is the heating cable for the devi water pipe, which can also be found in many retail outlets in our cities.
DIY heating water pipe
Craftsmen and those who want to save summer residents can be advised to make a heating cable on their own. To do this, it is enough to use the telephone field communication wire P-274M (field vole). The wire is relatively thin, hard, strong, in good strong insulation, can be used in water.
Voltage is supplied through a transformer at the rate of about 1 Volt per meter of double wire, current 8-10 Amps. It must be remembered that such a cable is not suitable for installation inside a pipe with drinking water. Good results are shown on a wire mounted externally on a plastic pipe. A self-regulating heating tape with machined ends is also quite suitable, as shown in the video
Monitoring the heating cable for water supply
The main point related to the efficiency of the heating system is its timely inclusion. To do this, there are special temperature sensors that indicate the temperature and the time on / off heating.
If it is not possible to constantly monitor the water temperature, it is necessary to use automatic regulation using a relay. It is also advisable to connect a color control indicator to the system for clarity and additional verification of the self-regulation system (if the indicator is constantly on, the process is inefficient). The use of a heating cable will benefit not only for a country water supply system, but also for a sewage system, because, for sure, many have come across the fact that in a bath, in severe frost, water freezes in the connecting pipe between the shower drain hole and a sewer pipe buried in the ground. Installing a heating cable will eliminate this problem.
