These pipes help in saving of energy and water. The continuous use of these pipes can help you in saving money and conserving water and energy.

There are also PEX pipes with oxygen barrier. The oxygen present around the pipe can react with other elements and can lead to corrosion. This can be harmful in case of internal fittings. This corrosion can lead to leakage. Therefore, it is important to prevent it. The oxygen barrier prevents this oxygen from coming in contact with other elements. Therefore, it saves the material of the pipe. Therefore, it is always good to use piping with oxygen barrier.

These pipes are resistant to breakage. These pipes do not break with continuous use under different temperature. Due to the PEX material, these pipes contract and expand with the temperature. But, there is no weathering in the surface. These pipes withstand this phenomenon for longer. Therefore, they do not break very easily or early.

This is because these PEX tubing are more temperature resistant than any other pipe. Due to this reason, you can also see them in radiant heating systems. When we pass hot water regularly from these pipes, it does not affect these pipes. Thus, they easily warm a room with radiation.

The material of the pipe gives it elasticity and flexibility. This is the reason why you do not have to make joints whenever you need to bend the pipe. This in turn helps in preventing leakages. Moreover, the overhead of using joints during installation is not there.

If there is any repair in metallic pipes of copper or any other metal, we have to draw halls into the walls or the floor. Moreover, the repair of plastic pipes such as PVC pipes also requires the same. However, it is very easy with PEX manifolds due to the flexibility of these pipes.

PEX tubing manifolds have many certifications. Therefore, they are completely safe for use. They do not harm the user in any way. There are no corrosive metals inside the pipe. Therefore, it is completely fit for use even if you use it for potable water. These are a few reasons for the popularity of these pipes. Use them and see their advantages over other pipes.

General requirements for storage of pipes, transporting and working with them.

The ends of the tubes should be closed or protected so that dust and dirt would fall into PEX pipe.Pri storage, transportation and working with pipes, you need to be able to save the original packaging.

You can not keep the pipes under the direct sunlight, so long as the UV radiation affects the properties of the pipe.

Work on storage tubes need exercise care not to damage them.

In the case of mechanical lifts, the equipment should not damage the pipe.

Steel slings, hooks and chains should not come into direct contact with the pipe.

The bottoms of used vehicles should be smooth, blunt, or any other protruding structures.

After fixing the pipes, heating circuit is filled with concrete. Before filling the obligatory in a hydraulic test system under the pressure of 0,6 MPa for 24 hours.

Seamless concrete floors, formed after filling the heating circuit performs several important functions. First, it contributes to a uniform temperature distribution on the floor surface, and secondly, assumes operating loads and protects against damage to the pipe and the insulation layer. The thickness of the concrete layer must be at least 30 mm, and the total thickness of the floor from the surface to the layer of insulation (including pipe) – 50 mm.

Heating circuit must be made of one piece of PEX pipe or fitting connected to the press, pouring concrete, prefabricated joints is not allowed. It should be remembered that the minimum bending radius is R = 5D mm.

General view of the floor heating system is shown in Fig. 5.1.

Double-layer structure of the protective tubing for cable (outer layer – corrugated PEX, internal – smooth CVP) allows, in combination with low weight and high resistance to external force loads easily and effortlessly extend inside the cable. Laying can be performed both summer and winter at ambient temperatures not below -27 ° C. Operating temperature protective double-walled tubes from -40 ° C to +90 ° C.

Where to use protective double-walled PEX/ LDPE cable

As part of any autonomous heating system, there is usually a water heater plant, which is intended for receipt and transmission fluid at different temperatures in different circuit. The water heater plant is not only the water heater, piping, connectors, regulating valves, pumps, actuators – that different regulatory system, which provides integrated management of all elements of the water heater plant to produce the necessary temperatures in different rooms and different thermal contours depending from external and internal factors.

For example, device management company WOLF consider the basic principles of water heater plants and heating system as a whole.

All device management, including the company WOLF, can be divided into manual and automatic, the latter usually have a manual control mode.

Manual control device for a single-burner R11 and R11-SB, provides manual adjustment of temperature in the water heater in the range from 38 ° C to 90 ° C. They have the security temperature limiter (STB), which disables the control system, burner in the event of overheating of the water heater, temperature controller, temperature indicator, the possibility of connecting the circulating pump heating circuit, temperature of the water heater.

Safety temperature limiter (STB) is present in any device regulation, as the manual and automatic, and ensures safe operation of water heaters and water heater plant as a whole. It is a sensor with an actuating device configured at a predetermined temperature off switchable 110/100 ° C and manual reset into position in case of alarm.

Control unit R11-SB is able to connect the horizontal and vertical water heater, a detached water heater, using a temperature controller SP-1. As a result, in manual mode is provided priority and hot water. The temperature of water heaters installed on the control unit R11-SB, or the water heater temperature controller SP-1.

To connect the two-stage burner device is used for manual adjustment R31-STAV, which has the ability to connect the water heater and hot water on a priority scheme.

Automatic control device (Automatic) WOLF presents Automatic R12, R16, R20 DigiCompact for single burner, R32 DigiCompact, R33, R33 / 4 DigiComfort for two-stage burners and RK-2, RK-4 for dvuhkotelnyh units with two and four mixing circuits.

All automatic control device WOLF controlled water heaters and water heater plants, depending on outside air temperature. So with a decrease in outdoor temperature will automatically increase the temperature of coolant in the water heater or in the serving line, and with increasing ambient temperature – decreases. All weather-control system contain a permanent electronic memory a series of curves reflecting the dependence of the coolant temperature from the outside air temperature. Each curve describes a heating system, insulation of buildings, climatic zone, the heating circuit. Therefore, simply select and install the necessary slopes for heating for all conditions. The best is the one indicator of the slope, which at the minimum outdoor temperature reached a maximum temperature of radiators, floor heating.

In addition to the control device it is possible to increase or decrease the temperature of the coolant, without changing the heating curve, and shifting it from the slope in the direction of greater or lesser temperature. All control devices have the additional regulation, which allows to quickly adjust the temperature of the coolant in the water heater in the event of a dramatically changed climatic conditions.

Automatic control device not only control the burner, ensure safe operation of the water heater, but also control various circuits and heating system as a whole. Adjusting devices R12 and R32 provide the work of one heating circuit and dhw priority. R16 – manages a single heating circuit, one circuit with mixer and provides heating water heater on the priority scheme. Automation R20 and R33 except the heating circuit and the circuit hot water control has two loops with a mixer, and R33 / 4 DigiComfort four circuits with mixer. Adjusting devices RK-2 and RK-4 are intended for two water heaters with two two-stage burners each. Have the ability to connect the burner stages, depending on the load, a smooth increase in water temperature in the water heater, electronic device control heating water heater. RK-control unit 2 controls two independent circuits with mixer, and RK-4 – four mixing circuits.

Adjusting devices series DigiCompact have great information display and two multifunction regulator, which allow you to quickly select any option and change it.

Automation WOLF provides seven modes of operation of the water heater and water heater plant. Mode to control the waste gas, which conducts a service engineer. Auto mode, when the water heater is working on one of the three programs stored in the memory controller, which can be modified according to individual requirements and at the same time is always possible to return to the standard program. Continued operation of heating, regardless of the installed program. Mode with low temperature or economy mode when the water heater automatically lowers the temperature of the coolant at the value that can be set individually in each case. The water heater can also be translated only in the regime of hot water with the heating system is turned off. Automation provides a manual mode, when the water heater provides heating fluid to the maximum temperature set in the parameters of the regulator, regardless of the outside air temperature. The controller has a mode of frost protection, by default, heating and hot water are included, but at the same time, a minimum temperature of the coolant to prevent it from freezing in the case of lowering the ambient temperature.

When you open the front cover control device can access the next level of management. Choosing the left regulator or that option, the right controller can change its value. At this level of control exhibited time, day, year, selected the program is the automatic mode; exposed temperature continuous operation mode or operating mode with reduced temperature, the slope of the curve of heating. Device control allows you to automatically switch the heating system from winter mode to summer and vice versa. Upon reaching the desired temperature in the summer control device disables the heating system, but it keeps hot water treatment. In automation provides the ability to view temperature regimes of different contours, as well as testing of all actuators.

Adjusting devices also have the level of control used service engineer to set the parameters that provide an autonomous and safe operation of the water heater and water heater plant. At this level, exhibited the minimum and maximum temperature of the water heater, the burner operating conditions, temperature limit protection of the heating system from freezing, modes of operation in the preparation of hot water, the influence of various factors on the contours of the heating water heater work and mixing circuit in economy mode.

Options at the level of control specialist may vary within specified limits, but apart from this there are factory set, which is always possible to come back and are fully ensure the efficient and safe operation of the water heater.

Device management firm WOLF have the opportunity to connect analog and digital remote control devices, which can be installed in residential premises for the convenience of management of water heater and heating system. Regulators have the opportunity to connect, through a special device, the phone that allows you to control water heater system with remote access.

The water heater plant is equipped with devices such regulation can operate almost without human intervention and provide the necessary temperature conditions in the room, depending on the season and the outdoor temperature during the day.
