The types of systems that is used to connect the water heater in the form of a flow-through cable to the water pipe

water heating methods to connect the cable to the water supply.

To date, there are three basic systems that use a heating cable for applying heat to your pipes, namely:

• Resistive system uses in its work water heating cable, which does not have the function of self-regulation.For such a system and a constant resistance characteristic for the design of heat supply to the tube requires a very accurate calculations.During operation requires constant monitoring of the temperature of heating cable.Due to the small amount of energy expended on work rezestivnogo cable, these systems use a certain demand among buyers.
• Zonal heating pipes is due to two isolated from one another, of conductors.Wires laid on top of these metal coil that has high impedance and the hinging one, then the second conductor, forms a parallel "zones" heat, about one meter in length each.

• most effective in terms of protection of pipes from freezing have an organizational self-regulating system.Connected water heating cables such a system also has two current-carrying conductors, but they are closed plastic shell.One of the properties of this material have a thermal conductivity of its dependence on the ambient temperature, and based on this, there is self regulation of heat generated.

elements for connecting to the water heater can be mounted from the outside, so the internal surface of the tube.

water heating cable installation can be performed by one or more lines along the outside of the tube.Depending on the desired heating power calculated amount laid parallel heater segments.It is also possible to lay the cable and the spiral, but must follow a certain distance between the coils.

Inside the aqueduct can also install the heating cable, but in this case the cable insulation must be suitable for the passage therethrough of water, which is used in cooking.Due to a more rigid construction of this type of cable installation is advantageously carried out on the straights aqueduct.

Construction of internal water heating cables are often used owners of gardens and farms.They have a water supply system is laid, open, above ground and the pipe can be frozen quickly in the winter.

Rules cylinder connection to the water supply.

When installing any cable pipe heating system it is necessary to observe the following rules:

• water heating pad cable to be carried out at a temperature below 0 ° C;
• connect the cable to the network for a short time, if it has lost its flexibility in low temperatures;
• sure to check the integrity of all the water pipes;
• when laying cable must not be allowed its intersection with the sharp edges of the water system;
• bend the cable by an amount in excess of $ 6 cable diameters;
• After connecting, check the insulation resistance of water-heating cable.This value must not be lower than at the Bat coupling.To carry out this manipulation is necessary to have a multimeter or a megohmmeter.

Pin to pipe water heating cable, you can use aluminum tape, keeping the distance to 300 mm.between the bindings.To avoid contact with the cable insulating material tube, and lay the tape over the whole length of the heating element.Temperature sensor water heating cable is installed in the coldest part of the aqueduct.
