PEX tubing and its simple installation

Tubing is a building block of a water supply piping system that has various advantages over the ordinary metal and rigid plastic pipes systems. This pipe is formed from the highly cross linked polythene polymers. The polymer used in the construction of this pipe is known as HDPE which stands for high density polyethylene. This polymer is allowed to melt and is then incessantly extruded into the tube. This type of the cross linking can be performed in various methods.
Pex tubing - smart alternative for traditional pipes There are immense advantages of this pipe which makes it applicable for vast applications. PEX tubing are flexible, do not corrode or develop certain pinholes, provide resistance to chlorine and the scale formation which are very common in other ordinary rigid pipes. Also it allows very few connections and fittings than other pipes. And the main advantage of this pipe is that it can be allowed to bend at 90 degree without any fitting or connections.

There are some connection methods that are required for the fitting of the PEX tubing to brass PEX fittings that make the use of the copper crimp ring and different kinds of PEX crimping tools. This copper crimp ring is made to insert above PEX tubing, then this fitting is pushed inside that pipe and after that copper ring crimp is crimpled above the pipe and fitting is done using the crimping tools. These tools, crimping rings and fittings are easily available.

Tools for PEX piping There is another fitting method that is known as expansion fitting method. This method involves the use of expansion tools that allows the increment in the diameter of the PEX piping. There are some special expansion fittings that are made to insert into the expanded tube and also shrink back to the original shape around the fitting. After that a white colored ring is made to crimp over the fitting to ensure the tight connection.

Corrosion protection of my brass ball valves

Corrosion protection is one of the most important requirements in the construction of pipelines (especially the trunk). Protection expose themselves directly to pipes, fittings, valves ( The requirements for corrosion-resistant coating is constantly being tightened, modern insulation materials help to protect pipes and fittings from corrosion for 20-30 years. Because of the specialization of our company, detailing corrosion protection of valves and pipeline fittings in the system of "Transneft".

The main documents governing the various kinds of protection of pipelines and fittings from corrosion, are GOST 51164 "Pipelines steel trunk. General requirements for corrosion protection ", RD-23.040.00-KTN-189-06" Rules for corrosion protection of above ground pipelines, structures and equipment facilities of main oil pipelines, OTT-04.00-27.22.00-KTN-006-1-03 " Technical requirements for external anticorrosion coating molded fittings and valves of the pipeline "; OTT" trunk pipeline. Fittings.
In the foregoing documents detail procedures for all types of work on application of protective coatings, the requirements for materials and equipment, methods of acceptance and control of the paint.
Depending on the location and conditions of the coating are divided into two types: the factory and line. Typically, in applications from contractors engaged in construction at the sites of Transneft, indicated that fixture shall be factory-corrosion coating. In practice, very few factories reinforcing its own exercise of protective coatings, especially on products for underground installation. Costs for the purchase of necessary equipment, materials, training of qualified personnel are sufficiently large. To dye valves according to the requirements of Transneft manufacturers attract specialized organizations that have licenses and permits for this type of work, and maintained by applying a protective coating on valve or on the territory of the plant itself, either on their own areas. Typically, such teams have a mobile painting of insulating and conducting work in the factories as well as "in the fields. From personal experience would like to note that the cost of the work on protective coatings that claim manufacturers valves are often substantially higher than the cost of these works, which take the actual perpetrators, while painting and in the factory and in our territory is held by the same materials , the same people and on the same hardware.
To protect the valves installed underground (both directly in the ground and in the wells) to the requirements of PAS-04.00-27.22.00-KTN-006-1-03 The most widely used materials of the Japanese company "Kawakami Paint FIG. Co.Ltd. "Brands FRUCS-1000A and US materials brand Biurs." These compounds are epoxy-urethane coating and consist of an epoxy primer layer and the outer layer of polyurethane. Plot the data coverage in parts insulated pipes and fittings by "hot" airless through special facilities. Subject to the technology of the work life of these coatings may exceed 30 years.

Circulator pumps for private houses and apartments

The desire for a comfortable life proper to man. That is why most manufacturers of household appliances from one year to improve its products. For more options, higher reliability, elegant design - everything is done to ensure that consumers feel a new level of convenience and quality. But is the sphere of which we seldom think in everyday life. If large and small household appliances constantly reminds about themselves, then such subtle, but essential devices such as pumps urbanite perceived solely as a prerogative of municipal structures. Typically, the existence of these aggregates, we remember only when problems arise, which it is impossible not to notice. Other business owners of houses and individual houses. They tend to thoroughly know why their economy but there are some circulator pumps, but also private entrepreneurs do not usually think about innovations in this area, preferring to buy well known and usually fairly simple model, assuming that they reliable technical innovations. Let us say at once, both of these categories of consumers caught up in stereotypes. And the citizen and the owner of the cottage can significantly increase the level of comfort, if we pay attention to the modern pumping equipment for domestic purposes. It may seem strange, but today the once simple pumps for domestic use produced by leading manufacturers with advanced technologies, and not inferior to their industrial brethren. There is another aspect: technical innovations in this area not only improve the quality of life, but also help save considerably, saving precious now electricity and heat.

Technical characteristics

Chemical properties

Pipes are resistant to various chemical solutions. If you need to use pipes for transporting liquids other than potable water, it is necessary to obtain a preliminary consultation with a specialist firm Everhot.

Saving forms

PEX Tubing Wirsbo

Wirsbo PEX Tubing system is a low-temperature system that uses the floor surface as a source of heat distribution. Installation of such systems requires knowledge of the foundations of their work and practical skills.
Despite the fact that they can use the same sources of heat, floor heating differs significantly from the radiator, in particular the methods of heat distribution.

Key features and benefits of PEX Tubing:

• heating element is the entire surface of the floor. There are no heaters. The possibility of a more efficient use of space in residential, office or other premises;
• Low coolant temperature, which is about +25-45 ° C;
• Uniform and beneficial to humans in terms of physiology, the distribution of temperature in the room at his height;
• Ability to use various coating floors (wood, stone or ceramics);
• Can be used for water heating virtually any source of energy from coal-fired water heaters, gas, oil or electricity to nekonvektivnyh sources such as heat pumps, solar collectors or geothermal sources;
• Hygiene - repeated lowering the amount of dust in the air space and with it the bacteria that often cause various diseases;
• High impact pleasant for a man of the thermal radiation (50-70%), allowing a higher thermal comfort in the room;
• Cost of thermal energy. In residential buildings -20-30%, and in rooms with high ceilings, for example, sports halls, exhibition halls, etc. - Up to 50% and higher!
• Optimum humidity in the room;
• In contrast to hot radiators (over +70 ° C) floor heating does not contribute to unfavorable human positive air ionization, which provides low-quality impact on human health;
• Lack of a strong source of heat radiation in the vicinity of Rights;
• In areas where people reside, the maximum temperature of the floor is by European standards +29 ° C, and the average temperature during the heating period varies within +23-24 ° C.

In PEX Tubing, almost 70% of heat is transferred in the form of a pleasant, gentle heat radiation, which is not conducive to the raising of dust in the air. Why is this happening? When the air temperature in the room +20 ° C average temperature on the surface of the floor in the heating season is 23-24 ° C, which shows that the temperature difference of 3-4 ° C. And with radiator heating, radiator temperature 50-60 ° C, a temperature difference of 30-40 ° C. That is a big temperature difference is responsible for the strong convection. which contributes to isolation from the floor and dust lifting up.

Popular things for PEX installation

PEX tubing can be used for various purposes. For example, the popular PEX fittings for exhaust ventilation. Consider, for example, an exhaust tube in the garage, which consists of PEX tubing for ventilation. It should be located not less than 1,5 m above the roof. Please note that you need waterproofing tubing where it passes through the roof to avoid leaks of rain and melt water.

Ventilation apartment or house - also not as easy as it seems at first glance. In today's environment banal air conditioner and air cleaner often enough. Come to the aid of PEX tubing for exhaust ventilation. The most common solution - inlet ventilation system in combination with several independent exhaust. In cafes, restaurants and other public places large numbers of people also need good ventilation of premises, and once again - producers can use PEX tubing for exhaust ventilation. There is another category of institutions, which simply requires PEX tubing for ventilation. It gyms and fitness centers.

Usually installed inside a metal tubing vent exit diameter of 125 and 160 mm and plastic vent tubing with a diameter of 160 mm. In another case, you can install and plastic vent tubing with a diameter of 225 mm. To avoid unpleasant odors and the destruction of sewage systems in the house, sewage risers must have a vent out the roof. To do this, too, fit plastic vent tubing with a diameter of 160 mm. Fans with built shumopoglotitelyami can join tubing with a diameter of 160 mm and plastic vent tubing with a diameter of 225 mm.

Methods of PEX tubing installation

* Continuous strip;
* Trenchless laying;
* Horizontal drilling;
* Laying on the mountain slopes and ravines;
* Laying in artesian wells;
* Cutting into the existing pipeline.

1. The method of continuous laying of pipes

The method of continuous laying of pipes is smuggling in PEX tubing in the pipeline is repaired with the winch.

Before laying of pipes welded PE whip, which extends through specially prepared for the purposes of reconstruction of the well.

This method requires the use of powerful winches, through which new pipe is pulled into the old pipe.

This method is used for reconstruction of water pipes with nominal pressure: 10-16 kg/cm2, sewers: 4 - 6 kg / media are.

Method of trenchless pipe made of PEX with an excavator

Laying pipes in old pipelines with an excavator
1-old pipe, 2 - PEX pipe, 3-Nylon Stick 4-movable roller; 5-nose-cone.

Laying pipes in older pipelines is an upgrade of the old pipeline systems. However, it is important to have a complete understanding of the forces and stresses experienced by the pipe during installation.

This shows how installation of PEX tubing with an excavator. Pre-boiled whip of the PEX pipe is placed on the mobile videos. At one end of the pipe or welded, or with a bolted connection, fixed nose-cone.

The end of the pipe with a wound in the nose cone of the old pipeline. On the PEX pipe is fixed one end of a nylon elastic stick, the other end is attached to the tooth bucket excavator. Smoothly, without jerks, gradually whip is drawn into the old pipeline.

With the introduction of PEX pipes in the existing pipe outer surface of PEX may be damaged, eg scratched, if not to take special measures. These measures include the removal of burrs and sharp edges with the existing pipe inspection using CCTV and the protection of new pipe in the area of administration, particularly in the area it traverses the trimmed edge of the old pipe. Care must be taken so that the depth of the scratches did not exceed 10% of wall thickness. It is therefore recommended to use PE pipes with wall thickness of not less than 5mm.

PEX pipe plus

As noted above, in the literature these issues almost no personal attention. The need to equip piping liners at the intersection of individual elements of the buildings can be justified by several factors.

Straight sections, such as risers from PEX pipe (PEX Tubing) are very sensitive to temperature changes and are able to significantly move. It is obvious that there must install the cartridges. This will create conditions for free movement of pipelines in the case of thermal strains at the possible installation and maintenance, seasonal and diurnal temperature extremes. However, we can not prevent movement of polymeric PEX pipe in the construction elements of buildings. To do this, arrange them joints so as to completely exclude the movement of polymer pipeline construction elements.

PEX pipe for you

However, significant noise sources are the other internal PEX pipe [2]. The corresponding arrangement [3, 4] permits such as sewer PEX pipe through the building structures (Fig. 2, 3 and 4) can significantly reduce the noise emanating from them (the noise level is reflected in the figures the number of arrows). Thus, the study of certain regulations convinces us that the consensus about the mandatory requirements for the arrangement of passages is not yet formed. This is understandable, since the conditions of the intersection of metal and polymer PEX pipe are very diverse: they are material building elements (concrete, brick, wood, etc.), and the various elements (load-bearing walls and walls of living rooms, bathrooms and basements, as well as the overlap ). It is important, and what elements (walls, floors, etc.) traversed by the pipeline, in which the premises is carried out (bathroom, living room, etc.) and what a way to mount (indoor or outdoor) is used. It is from these factors in each case will depend on the criteria for cost-effective arrangement places the intersection, execution of which alone would ensure a reliable and durable operation of any sanitary system from any of the PEX pipe.

Internal PEX pipe systems

These issues are due to the fact that it is always important to know how the simpler, cheaper and more reliable for trouble-free service elements of buildings and pipelines to equip their intersection with the building designs. The analysis of numerous regulatory and literature data does not permit a sufficiently convincing answer to these questions.

Thus, in SNIP 3.05.01-85 ("Internal sanitary systems) - the basic document on the rules of national importance installation of internal systems - there are no recommendations on the arrangement of the pipeline goes through the elements of the buildings, except the following:" non-insulated pipe systems, PEX radiant heating, radiant heat, domestic hot and cold water should not adhere to the surface of building structures ", and" distance from the surface of plaster or lining up the axis of uninsulated PEX pipe with a diameter of nominal bore 32 mm inclusive, in the open strip should be between 35 to 55 mm, diameter 40 -50 mm - from 50 to 60 mm in diameter and 50 mm - was adopted by the working document. Do not reflected sufficiently rules of crossing the elements of buildings and pipelines in the national norm SNIP 2.04.01-85 ("Internal plumbing and drainage of buildings") on the design standards of domestic water and wastewater systems of buildings. Section 17 provides guidance, according to which:

* Aisle seats risers through floor should be sealed with cement mortar to the entire thickness of the overlap (n. 17.9g);
* Riser section above the floor at 8-10 cm (up to horizontal diverter pipe) should be protected by cement mortar thickness of 2-3 cm (§ 17.9d);
* Before burying solution riser pipe should be wrapped roofing waterproofing material without a gap (clause 19.9e). However, this statement applies only to the risers sewer systems. Consideration of various regulatory recommendations on arrangement of the pipeline crossing elements of the buildings shows that they are very incomplete and, moreover, are sometimes contradictory.

Types of PEX tube connections

Today the market in a variety of fittings are presented for metal systems. Talking about how adherence to the tube should be divided by all the fittings on the screw (threaded) and media (press fitting).

In the first case the connection is achieved through the pressure that arises when tightening the nuts on an open ferrule. The figure shows the device of one of the threaded fittings company Pex Al Pex . To seal its tip has a special retention profile with the radial notch and the two O-rings, immediately adjacent to the pipe. Tight connection fitting body with a tip is a special seal. Another gasket is placed between the tip and the end of the pipe. This piece, which eliminates direct contact of the aluminum layer with a metal fitting and thus prevents the electrochemical corrosion, it is usually made of Teflon. As the seals are also recommended teflon gaskets.

As already mentioned, mounting screw connection does not require a special tool: it is made with two wrenches (one nut is tightened, and the second is resistance). To facilitate the introduction of the sealing rings and extend the life of the fitting, use silicone grease. It is prohibited to use mineral oil or other petroleum products. Typically, grease is a range of products produced by manufacturers of PEX pipe.

Installation of PEX tubing

Today in the heating, hot and cold water pipes are successfully used, made of polymer materials or using them. In previous issues of the journal "Everhot" commented mostly on technologies based on the use of flexible pipes made of crosslinked polyethylene (PEX). At the current market of engineering equipment with this product compete vigorously Aluminum pipe. To speak clearly about the advantages of the latter can not, although it is known that a number of reasons, including - psychological, USA customers often prefer the PEX plastic.

An important quality of PEX pipes is their adaptability for installation. They are easy to bend, do not require exact fitting of linear dimensions, with no extras save the form, which gives them the installer.

Major foreign companies, manufacturers do not release PEX pipe themselves, and lead integrated production related equipment: reservoirs, fittings, fasteners, etc. Connect and the connection of pipes with special fittings does not require threading or welding and the application does not take much time.

Specificity of metal-tube requires careful handling it, strict observance of assembly technology. This is especially important because in most cases, the rules require a hidden strip of PEX pipe, where a bad leak is extremely undesirable.

PEX fittings are vital to ensure the installation of the PEX tubing systems. One of the most important fittings is the PEX coupling that is increasingly being used to connect the ends of various PEX piping. PEX couplings are of utmost relevance when it comes to connecting the PEX tubing systems.
The most commonly used materials for the PEX couplings are plastic and brass. Out of these two types, plastic PEX couplings are primarily used to check the pressure. The main purpose of PEX couplings is to ensure secure installations by bending tight corners, changing sizes and splitting branches. Straight connectors are the most basic types of PEX couplings that are increasingly being used to various connections of toilets and faucets.
There are basically two types of connections that are being used which include the crimp connection and clamp connection. Copper crimp rings and crimp tools are used for the crimp connection, whereas, clamp tools and stainless steel clamps are used for the clamp connections.

Stiebel Eltron or Takagi?

Saving water heater - this is, simply speaking, the expansion tank, which is installed heater and protective anode for the prevention of scale. Average power storage water heater of about 1.2 - 3.0 kW, and it is perfectly suited to the requirements of our power. As for the cost, it is determined by the volume of container and the name of the manufacturer. Average price - Italian Termex and Isea (from 70 to 500 ye). More expensive water heater will cost you from Rheem, Stiebel Eltron, and Takagi (Japan). Their value of 200 y.e and above. The principal difference between expensive and cheap is not just in English and German heaters plenty of space is insulated (due to its water loses only 5 degrees per day), and they are covered with expensive titanium enamel.

The more expensive model, the more it needed technical functions. For example, quick radiant heating (when the water cools to 0.5 degrees, turn on automatic radiant heating).

Before you buy a water heater, you should determine for what purpose you will use it. If you only want to wash the dishes, then you have enough water heater to 10 -15 liters. To take a shower - no less than 30. For the needs of a large family of at least 100 liters. Note also that the majority of storage heaters work under pressure, they are called artesian. There is also the so-called liquid - water, they poured directly into the tank, and they are designed for one faucet (sink).

Electric water heaters. Features of the national economy.

Consider the work of electric water heaters from the standpoint of physics. In the first phase electric power is converted into heat, here efficiency depends mainly on the material of the radiant heating element (from the loss of electricity in it and from the heat). In the second stage heat is transferred from element to water (efficiency depends on the area of contact with the water element). At each stage, some of the lost energy. Depending on the type of device, the efficiency is in the range 0,9-1,0. The magnitude of the Tankless water heater efficiency is close to the similar figure of perpetual motion, ie to 1, but, unfortunately, the loss still exists.

To do this in the Tankless water heater installed two radiant heating elements on the 0,8 or 0,9 kW, pressing on the front panel of EVN, you can turn on the economy. These models of water heaters quite expensive.

There are general guidelines for the selection and mode of operation of any EVN. Do not choose too small storage water heaters. With long-term mode of operation is better to use higher-capacity unit, but at 60 ° C than at 85 ° C. Temperature 60 ° C guarantees:

* Gentle treatment for the reservoir and pipelines by using water saturated with chemicals causing corrosion;
* Less fouling, which destroys the protective layer inside the tank;
* Reduction of energy consumption to maintain the temperature of hot water.

Accumulator for individual water supply systems

Outwardly, hydraulic accumulators are very similar to flanged expansion tanks like Extrol 15 or Extrol 30 of radiant heating systems. However, the appointment and service conditions have other, hence there is a positive difference.
First, the mode accumulator over loaded. In normal operation, its frequency response is from 5 to 15 times per hour with a well chosen volume accumulator. If the volume is chosen correctly, this value can increase up to 20-30 times per hour. Of course such an operation requires a reliable, flexible membrane which can withstand a large number of loads.
Secondly, hydraulic accumulators are used in household water supply systems, so the material must not be toxic and permitted for use with drinking water.
Thirdly, the water in the water supply system in most cases comes from a well or wells. It is saturated with oxygen, which is released and accumulates in the membrane. Therefore, large accumulators at the top of the diaphragm is pipe and valve for venting the air. The appearance of such accumulator presented earlier in Figure 5.
Fourth, hydraulic accumulators usually placed on the line of cold water in the water supply system, so in terms of the temperature at which they operate, the regime more sparing. Typically, the water temperature in the system can not exceed 30 ° C.
As expansion tanks of heating systems, hydraulic accumulators are filled with water is not completely. The volume of "issue" with the work accumulator water is less than the net volume expansion tank heating system.

The radiant heating system "warm floor"

One of the most common today is radiant floor heating. Most consumers find water "warm floor". As the coolant can be used and frost free agent, but the heat will still be water.
Let's look at one of the most common water floor heating systems, which is popularly called Stalinkas. It is a structure consisting of two-pipe routing and having an upper filling. Most often these systems are found in low-rise buildings Stalinist.
The main advantage of this system is its reliability. In addition, it requires in relation to a no maintenance. Ways to create Stalinkas only two:

* According to a parallel scheme
* According to the vector diagram
In the first case, the location of the heating system was determined by type of location of bottling. The system, made by a vector diagram, more often called - with a fair movement of coolant. Among other schemes, it is the most reliable. In addition, her work is characterized by constant uniform.
So, as mentioned above, the main advantage of this system is the uniformity of its heating radiators. That is, you do not have to wait until the required space heats up, going from room to room.
But despite this advantage in our days, the system is mainly used only in country houses. This is explained by the fact that her work is not possible at elevations above the fifth floor. This significantly limits the ability of the Stalinist heating system, but at the same time, does not make it less effective.
Order heating private houses can be in our company.

Invest In Radiant Heating for an Economical Choice

If you want to upgrade your existing heating system but still want to keep costs under control or better still, reduce electricity costs, then radiant heating devices are the best solution.

Given the fact that modern radiant heating devices are standalone floor units, they have the ability to heat up the whole room easily and rapidly. These units can be plugged into existing wall outlets. However, before connecting the device, you should check the existing load over the electrical circuit, which has the unit plugged. You must also check for the amperage in the breaker or the fuse that serves the outlet. Make sure to jot down this information.


You will also need to add on the dimensions of the area that has to be heated such as floor width, length and ceiling height. Once you know this information, it becomes easier to purchase the radiant heating at the store. Once you purchase an economy unit, you might need an additional thermostatic switch for controlling temperature. It is a great idea to invest a little more in a thermostat that comes along with timer device in-built. This enables you to operate the radiant heating unit even at low temperatures even when the room is empty. The typical cord length is six feet or even lesser, while other radiant heating units might necessitate an electrician for installation.

The main installation entails placing the unit near the outer wall couple of inches from the floor and placed away from all dressers, furniture, drawer chests etc.

What to choose - hydronic or electric heating?

Consider the water ways and PEX floor heating. Particular attention is paid to the features and advantages of PEX systems.

The value of thermal comfort for the health, performance and mood can not be overemphasized.

To the room was comfortable conditions, air temperature should be as little different from the average temperature of surrounding surfaces, and the temperature of the heating devices should be as little hotter than the body.

This requirement is fully consistent with the system "warm floor". Floor heating systems radiate heat evenly throughout the floor area, eliminate the formation of convection currents that create drafts and carrying the dust into the air. With no radiators, pipes, wires outside housing becomes more aesthetic and functional.

Floor heating can be done in two ways: using hot water or electricity.

With water heating in the floor to lay pipes through which circulates the heated liquid and the electrical uses special heating mate, which generate heat when passing by them current.

In terms of heat, both methods are equivalent. But there are several additional conditions, which should correspond to the heating system and which should receive special attention.

The first condition - is security. Too high a temperature (40 C or more) can cause illness, even the feet. When a liquid is heated floor needs a separate circuit with low temperature coolant, or a special system of regulation. In PEX tubing systems, this condition is fulfilled automatically install a special thermostat.

Second - is reliability. Replacement or repair of floor heating require significant expenditures. In water systems use special plastic or metal pipes from corroding materials. To ensure the reliability and integrity of the system, before concreting, as well as in the concrete, it is necessary to produce test tube under the pressure of not less than the black bar to check all connections and seals.

How to choose a tankless water heater for apartmens and house

Summer - season not only leave, but the hot water outages. Urban residents within three to four weeks, forced to return to the antediluvian techniques in personal hygiene - wash basin and teapot. Or maybe do not care about the vandalism of public services and establish a self-contained apartment hot tankless water heater? Shortage in boilers in the stores, so only select and install it should wisely.

In Europe, 35% of the housing stock is located in the autonomous supply of warm water. Every third resident of Germany water heats the boiler of Siemens or Takagi, and the entire Israeli army to clean the shower, attached to the device Atmor. Why do not we turn to their experience? Moreover, the hot water as disconnected, and will turn off every summer. On the Russian market water heaters are models of leading Western manufacturers - Takagi, Siemens, Electrolux, AEG, Stibel Eltron, Gorenje, Ariston, BAXI, Atmor. And the first question that needs to ask itself the buyer boiler: what type of device he needed - savings or Takagi Tankless.

In the instantaneous water heater heats water only when its costs, and directly into the stream. That is, you can use it as a normal centralized hot water supply - opened the tap and wash up. In the storage water is heated in advance, depending on the power and scope of the instrument, it must include an hour, and even a few hours before you have a need for hot water. In the warm water flow heater can spend all you want users in a row, and in the storage capacity of 30 liters of hot water enough for one not very generous souls. Then wait for hot water again.

It would seem that everything is clear: to take Tankless heater. Manufacturers of these devices actively using all of these advantages Tankless heaters in its advertising. But in reality the problem of choice is more complicated.

- The "dead" Tankless heater, which allows you to get a weak trickle of warm water from the mains power 5 kW. Such power in a modern apartment has only one place - in the electric outlet. Total apartment area network (wall outlet) does not allow for devices with a capacity of more than 2 kW.

PEX tubing and Copper pipe

Everything related to copper pipes.

Copper - one of the first metals reclaimed by humanity. But this does not prevent it, and today remain in demand in different household structures and devices. A special place in this series cover copper tubes for various intra Communications ..

Despite the long history of existence, copper pipes continue to compete successfully with the modern "family" - plastic and metal water pipes. And in many ways much superior to them. Copper pipes are practically impermeable to various viruses and bacteria, as well as fats, oils, herbicides, insecticides and other harmful substances. Chlorine contained in tap water, has no damaging effects on copper.

Moreover, chlorine, as a strong oxidizing agent, even prolong the life of copper pipes, because after about 100 hours operation on the inner wall of the pipe forms a thin but durable protective layer sanitary engineering.

Valuable for water supply systems is another property of copper pipes - they are not subject to the rise on the inner walls of organic

and inorganic deposits. The obvious advantages as high stability temperature differences (range of operating temperatures for copper pipes ranging from -200 ° C to +250 ° C) and low coefficient of thermal expansion.

When comparing the properties of copper with other materials attracts the attention of its high plasticity, which increases the safety of water: copper pipes, in contrast quilting, are not afraid of freezing in water-filled condition. A resistance to ultraviolet radiation distinguishes copper from PEX Tubing, which under the action of sunlight begin to evaporate. Finally, low roughness (less
than steel and even plastic pipes) makes the same conditions using copper pipes of smaller diameter.

The use of polypropylene pipes: external utilities

Outdoor PEX tubing communication include thermal network, water supply and sewage system. One of the enumeration is enough to understand how important they are for the normal life of any city. They are also required for the townspeople, as refrigeration for storage of perishable products. And just as in the case of refrigerators, the absence of these undoubted benefits of civilization, we are starting to notice, only if there was a malfunction of any of these systems. Central heating, water supply, sewerage - for the implementation of each of these systems need reliable pipe, the quality of which depends on whether the work of engineering services uninterrupted.

At the present time to build and repair of external engineering networks are increasingly used polypropylene pipes. However, the scope of the polypropylene tubes are much wider, because of their unique properties. Suffice it to say that it is possible to transport various chemical solutions. It is no exaggeration to say that the polypropylene pipes for the economy become as necessary as cold stores in the summer. In those cases when you need a special strength and durability of pipes, used their reinforcement by special trains, most commonly used aluminum and fiberglass. Reinforced PEX tubing on operational parameters may well replace steel pipes, known for their reliability. One of the technologies of reinforcement lies in the fact that the pipe is covered with a layer of aluminum foil on top of a layer of polypropylene. Thus we obtain three-layer construction - two layers of polypropylene and between them a layer of aluminum. Pipes manufactured by this technology, different lower coefficient of thermal expansion and can be successfully used for the construction of thermal paths.

Regardless of the technology of manufacturing all plastic pipes are resistant to corrosion and looks quite aesthetically pleasing, even without paint, which distinguishes them from the metal pipes. Through the use of plastic pipe during installation of the pipeline achieves great savings. It manifests itself in practically all phases of construction. For transportation of plastic pipes do not need heavy equipment and installation is done quickly enough. When laying pipelines in addition to PEX fittings, tees and other fasteners can be used for welding, which is done using special welding machines.

Taco pumps (dual)

Dual pumps can operate on a parallel circuit. This makes sense when you want more performance at a relatively low pressure, or when you want more processing power for a short period of time. In parallel work is possible to use the pump with a smaller engine, while having far greater potential for energy savings. All the characteristics of pumps with wet rotor "also include a description of parallel operation of a dual pump.

Characterization of two pumps operating on a parallel circuit is obtained by adding the productivity Q (m3 / h) of each pump at a constant pressure of H (m). But keep in mind that this characteristic for dual pumps operating in parallel, will be somewhat less. This is due to the pressure drop in the housing dual pump for high performance.

Universal Tankless Water Heaters

Approximately one-third of our population lives in individual houses and rundown apartments with stove heating, spending much time on the content of furnaces and furnace. It would not have been good stoves, they spend a lot of fuel, because the rate of use is low. Fuel, as they say, "flies in the tube. Furnace heating does not even maintain the temperature during the day in the apartment: it varies from normal in either direction to 10 degrees, and it is harmful to human health.

In the newspaper "New York Times" on January 13, 1985 under the title "Does warm oven?" Published an article by engineer A. Bykeer and correspondent A. Abigman, which describe the sad state of furnace heating and raise the question of its improvement.

I was young (as a former masonry, and then - civil engineer) had to put a lot of different design and brick oven. Unfortunately, they all violate the accomplishment of an apartment, demanded a large fuel consumption and time-consuming for fuel and maintenance. Therefore, you need to move the device hot-water heating small houses and apartments. And for this it is necessary to develop a versatile compact system, that they were given water and heating, and hot water flats.

The author of this book was developed such a combined system of water heating, hot steam and water, which eliminates many of the shortcomings of existing systems and significantly reduces labor costs for maintenance of the system, creates a comfort that is comparable with the conditions of modern well-maintained apartments.

Currently, much attention is paid to the development of horticulture cooperatives, where people allocated plots of land, usually built garden houses, which are used not only in the summer. Often the question arises - how and what to heat a house? Recommended electric heaters of the road. Offered and systems that use solar energy. Unfortunately, they can not be used in cloudy weather. Also known design solar installations are not without drawbacks. For example, in the newspaper "Communist Tajikistan on 06.09.87 was published information about solar energy. The fact that it offers to customers is important, but the installation was deficient:

* Valid only on sunny days, no accumulation of stored energy;
* Solar panels are flat and motionless - directed all the time from one angle to the sun.

Presented to the reader combined system allows the use of solar and battery, and the design is such that there is no need to rotate. You can still reserve accumulated heat.

PEX heat transfer plates

The radiant heat is being widely used to promote various heating systems for both residential as well as commercial sectors. The idea of generating the radiant heat seems easy however getting a heat system that uniformly distributes heat is tough. PEX heat transfer plates are one of the best ways to promote radiant heat systems.

How do the PEX heat transfer plates work?

These heat transfer plates work efficiently by distributing the radiant heat from the various PEX tubing, piping and valves. These heat transfer plates are available in variety of shapes and sizes to suit the requirement of the users.

Due to the molecular structure of the Brazed Plate Heat Exchangers is uniform because these are cross linked and thus offer a laminar flow. The PEX heat transfer plates are available in single and double width. Depending upon the thickness of these plates they can deliver a wide range of heat over a large area and that also for a longer duration. Another feature that decides the amount and rate of heat transfer is the design. The amount of heat transfer will depend on the shape and the heat would be delivered in the units of BTU per hour.

The use of these PEX heat transfer plates is that they can work in extreme weather conditions, both hot and cold. They do not get brittle at the temperatures below freezing point. Their cross linking nature makes them highly bendy so they can be easily molded and laid down in various subfloors, snowmelt systems and other radiant heat systems.
