Construction of water supply system in the country winter

How to choose the heating cable.

There are a number of proposals to protect the sewer and water pipeline from peremerzaniya at low temperatures.One of the most affordable and easiest is to use a heating cable.

How it works:

• heating cable does not allow to freeze water or sewage;
• Performs heat saving function for external heating passage from one building to another, which is an important aspect in terms of energy savings;
• Allows you to save a certain temperature in the system;
• Prevents condensation to form in the pipe, and thus prolongs the life of the thermal insulation;
• It can produce in a certain place the initial warm-up and to ensure the smooth passage of fluid a certain temperature.
  

To date, the method of heating cable used in several kinds of systems:

• Self-regulating, which is equipped with special heat-sensitive matrices, which gives the ability to control the power of the heating wires, depending on the temperature change in the water.The advantage of this system is that the cable is not allowed to overheat, and also allows to save energy.
• resistive, which is equipped with heating cables constant resistance.Entering such a cable in operation is performed only after accurate calculations and more careful control over his work.Disadvantages of this system is the rapid deterioration and the need to purchase additional devices, which will regulate the operation of such a system.

Methods of heating installation.

Which method to use in the heating system will depend on the location of the pipes, their kind.Also taken into account, whether this will be carried out on an already laid pipes or new.

mounting method can be two:

• Outer;
• Inner.

Laying the heating cable on top of the pipe (external method) is more convenient and simple way.If your communications are made of plastic, they should be pre-wrap tape and only then to carry out cable laying.

Internal installation is applied when the pipeline is already laid, it should be noted that this type of insulation is not suitable for water pipes.

In any case, it is necessary to choose a wire to heat that it will release was much higher temperature in the pipeline.Cabling is made along the tube parallel or spirally, it depends on the required computational capacity.Cable itself is covered with a waterproofing and heat (this can be a foam, glass wool yl other materials).A layer of insulation has a thickness of not less than 10 mm.

After that, be sure to secure the wire using a special mounting tape.And the last layer - aluminum foil wrap design, which makes it possible to evenly distribute the heat.

When planning the system and procurement of materials, be sure to also acquire the necessary assembly and fastening elements, such as valves, temperature sensors, switches and so on.Ask for help in specialized stores, consultants whose prompt and help you choose the quality you need and the items and installation for better use the services of a professional plumber installers.
