Heating cable for water

To provide special care pipeline system, which runs deep into the ground, the heating cable is used for plumbing.

It will support necessary for normal circulation of the fluid temperature and protect it from freezing.

require extra care tube on which the hot water flows in winter.

Very low temperatures can cause excessive condensation and frosting, destroying not only metal, but modern plastic products.

what the market offers?

Before you buy a kit for water heating cable, you must decide on the proposals in the market.

It is produced in two versions:

1. Self-Regulatory;
2. Resistance.

widespread self-regulating heating cable for the water system, which is based on the semiconductor matrix.

When the ambient temperature varies, the matrix changes its current conduction characteristics, thereby changing the heating temperature.

The self-regulating cable two conductors made of copper, which flank the polymer resistor on both sides.

When voltage is applied, the latter is heated to a certain temperature.

resistor increases in size and decreases the load current, reducing power and cooling down the cable.

This cycle recreates self-regulating effect.

Since the entire length of the load varies depending on the conditions around the pipe section is supported at each specific temperature required at a given moment.

Not less popular resistive heating cable for water, working on a completely different principle.

He will warm all the time, when it is supplied with electricity and does not regulate its temperature depending on the surrounding conditions.

missed by pipeline resistive cable, it is needed for the care and supervision of his condition.

should be familiar with the characteristics of the product with the purchase, paying attention to its rated capacity.

If necessary internal heating cable for water, preference is given exclusively resistive products.Thus

power to not more than 10 Wm / m.For outdoor installation it is recommended to purchase a cable, a power of 15-17 W / m.

proposed model is very expensive market.

To find a replacement, you can use a self-made heating cable for water, which is required for the manufacture of:

• metal tube;
• heating element (cable that will go current);
• aluminum tape, which is attached by a wire to the pipe;
• heat insulator.

To automate the process, set the thermostat.

As an actuator used triac (contactless switch), which is able to withstand loads up to 10 kW with the heat sink and up to 2.2 kW without him.

Production Pipeline heating cable - a serious business that requires knowledge of electrical engineering and compliance with all safety regulations.

Any error bude cost more than buying a prefabricated kit.

Installation

organize the installation of the heating cable for the water supply system in two ways:

1. inside the pipe;
2. the outside of the pipe.

pulling the heating cable inside a large pipe should hold master capable to calculate the parameters required for the heating system equipment.

Working from the mains cable lies in the water, making it a high hazard.

in private and suburban homes, where pipes plots rarely exceed 2-3 dozen meters, can be carried out independent internal cable assembly.

During work it is necessary to observe a number of rules:

• In areas where the cable is introduced into the pipe, installed adapter and T-piece, observing the norms of sealing;
• The adapter is screwed into a special cutting, and then run the cable inside it;
• banned cabling in the shut-off valve, and in a place I hang a warning sign.

Outdoor installation of the heating cable for the water supply system is more secure if to protect the operating element from the impact from the outside.

There are several different ways of stacking:

• One cable in a straight line along the pipe;
• several cables in a straight line along the pipe;
• wavy styling;
• The spiral styling.

The entire length of the cable must fit snugly as possible to the heated product.

Attach it can (do not use plastic tape) using aluminum adhesive tape every 25-30 cm.

then applied an adhesive tape along the entire length, to prevent contact with the insulator.

If you swing the cable around a plastic pipe, the surface also wrapped with tape on an aluminum base.

Along pipe fittings cable must be laid in such a way so as not to impede access to it.

purchasing working set, it is always there to guide the heating cable for water with a description of the product parameters, and other of its features.

Before starting work, it must necessarily examine.

If the cable is wound or spiral wave, you need to make sure that the distance between the segments are the same.

This will ensure uniform heating over the entire length of the pipeline will increase its effectiveness.

in accordance with the instructions in the instruction is carried out to connect the heating cable to the water pipe network.

It can be done with the help of ready-made adapters sold in the market or via terminals.

Where to buy and how much it costs?

is not difficult to buy a heating cable for water with a variety of parameters.

It is freely available on the structure of markets or plumbing stores.

Today, more than a dozen manufacturers offer their products.

most widely used products and firms Nelson Limitrace Thermopads, brand domestic production HBS.

Today, the price of heating cable for water does not depend on power, and the firm, producer and model parameters of the proposed product.

example, Nelson Limitrace CLT Series cable capacity from 9 to 26 W / m is from 440 to 500 rubles per square meter.

In turn Thermopads FPC SR with a capacity of 10 W / m can be purchased for a modest 250 rubles.

In general, the cost of the following:

• Without Braid - 70 rubles;
• braided - from 120 rubles.

provided on the product warranty is 20 years.
