Little Giant Pumps

Little Giant Pumps, developed by experts of the Little Giant - is a versatile pumping units used for drainage of industrial and domestic waste water, fluid handling to wastewater treatment plants, pumping out rain and surface water. With a special one-piece design with different types of impellers, Little Giant pumps can pump liquids containing higher amount of abrasive and fiber components.

Little Giant Co. has produced the first models of pumping equipment in 1989, and, as evidenced by positive feedback from consumers, the use Little Giant Effluent Pumps leads to an increase in productivity pumping stations with a significant decrease in the cost of their care. Moreover, the effectiveness of sanitation increases not only the replacement of obsolete units, but also during the installation of pumping equipment series Little Giant Sewage Pumps instead of modern foreign-made pumps.

Among the large selection available on the market of imported plumbing pumps, and many are indeed examples of high-end technology. That's just the level of their suitability for use in the Russian conditions is extremely low so that it is almost always expensive equipment operate smoothly for a long time and at the proper level.

Broken snail, broken impellers, a burned-out pump rotor, worn hydraulics or ongoing mechanical seals - fairly common types of injuries Grundfos pumps, after a short service at the local water utility companies. Very often, the discrepancy of sewer systems to European standards, regulations, specifications, etc. is the reason for denial of service centers to repair the pump. And all that remains is the owner of a failed pump - is the purchase and installation of spare parts, often at a cost of only slightly inferior to the new unit. And in those rare cases where all conditions of operation can be aligned to the required standards and in the presence of all necessary additional equipment, such as the shield of automatic control, maintenance of imported pump still leaves a lot of money.

The reason is the high costs and the price of bearings, mechanical seals, gaskets and other, requiring the timely replacement of parts, and that the installation, repair and maintenance of Grundfos pumps must be carried out by experienced qualified professionals, whose content the state enterprises are also expensive. It turns out that the purchase of imported plumbing pump - just the beginning in a series of upcoming expenses.

That's why today is such a popular low-cost domestic pumps, among which pumps Little Giant highlighted a number of its advantages. Compared with pumps from other Russian producers, such as pumps Circulator Pumps, Transfer Pumps, Condensate Pumps not afraid of flooding - very common in sewers. Besides pumps "Little Giant" structurally suited to automation, which greatly simplifies their maintenance. Which can not be said of most domestic units, to control the operation of which requires the presence of the operator and periodic adjustments and debugging equipment.

Moreover, the inability to automate starting the engine to open the valve inevitably leads to water hammer every time you start and stop the pump, and the lack of an automatic fluid level check - to the rapid deterioration of the impellers, check valves, gate valves, pressure gauges, coupling, pipeline.

Avoid these problems and allows the equipment pump control panels, through which plumbing units Little Giant is a complex automated, self-oriented in a liquid that can track and maintain the water level at a given value. Self-diagnostic system monitors the pump pump rotor windings changes in temperature, humidity degree of isolation and, in case of deviation from the allowable loads and to detect leaks, displays the data on the bulletin board. Ease of operation of pumps Irtysh is also achieved through plug-type connections, allowing quick and easy enough to dismantle the unit for maintenance and set it back in line.

Summing up the above, it should be noted the following advantages, which ensures operation of plumbing pump Irtysh:
1. The small cost to purchase the pump.
2. Reduce operational and maintenance costs.
3. Reduce time spent on maintenance.
4. Compactness of the single-warhead Little Giant Sump Pumps to reduce the volume of construction of sewerage systems.
5. The process of pumping effluent becomes completely automated. There is no risk of accidental flooding.
6. Increased energy efficiency pumping stations: first, due to optimally matched equipment, and secondly, due to improved flow-through unit.
7. The broad scope - from pumping rainwater to the pumping of clean water.
8. Environmentally friendly use of running Little Giant Utility Pumps provided a low level of noise, vibration and the lack of heat.
9. Possibility to order the pump with the necessary operating parameters corresponding to specific technical requirements.
10. Finally, the Little Giant Submersible Pumps - a modern high-performance, high quality and reliable equipment, adapted to work in the USA context.

Pumps and pump equipment

To answer these questions must consider the characteristics of pump units in a group of parallel connected pumps. Work the pump unit in the group is fundamentally different from the conditions of a single unit. Maximum supply a single unit due to the minimal hydraulic resistance pipeline and the correct choice of pump shift it to the high values of the innings is impossible. Therefore, the operating point at the same time is a boundary that prevents the displacement unit in a zone of possible occurrence of cavitation and overload the pump rotor drive.

When working in a group of any change in status of any unit, through its inclusion in the closed (shutdown) or regulating the speed of the impeller changes the state of the system. In this case, a redistribution of load between the units, which can lead to an increase in supply of one group of units with the risk of getting into the zone of cavitation and overload and Little Giant pump Little Giant pumps Little Giant submersible pumps drive the other group with the risk of hitting them in the region of instability and surging.



For this purpose, we developed a mathematical model of the pumping unit with adjustable drive and is composed of a special computer program, allowing to scan characteristics of practical interest range of loads. At the same time as the initial data about the pump is its pressure and cavitation characteristics, as well as the characteristic efficiency. As background information in the program also introduced the following parameters: power of the Taco drive, the difference between the elevations of water level in receiving tank and the axis of the impeller, the dependence of head loss in the suction line of the pump from its filing, the maximum and minimum allowable values of the frequency of rotation (K = nm / nh, where nm - the current speed of the impeller, nh - nominal), the minimum acceptable efficiency values.

Grundfos Pumps

In any case, you have to disassemble the pump and remove the shaft obstruction. The special design of hydraulic parts with advanced impeller pumps Grundfos company, allowed not only to once and for all get rid of this problem, but also to ensure greater protection of the impeller from the effects of friction particles in suspension and shock loads. In addition, these pumps are used alloy impellers made of different materials, which when exposed to shocks are more reliable than welded.

The presence of such features as double mechanical shaft seal in oil-filled chamber and the oil-filled Grundfos 15-58 pump rotor, cooling pump ensures even when dipping it into liquid in less than half.

A distinctive feature of the Grundfos 15-42 pumps is the presence of grinding mechanism on the input. These pumps are specifically designed for pumping plumbing and liquids containing long fibrous particles. They are able to grind all the suspended inclusions, such as hair, tissue, pulp, down to individual pieces of plastic and wood, in a gelatinous mass. Yet they have higher pressure head characteristics, since they can use smaller diameter plumbing pipeline without any danger of clogging.

On these design features can be said for quite some time. Unfortunately, many sellers, in addition to data listed on the label of the pump (which is mainly flow, pressure and power), they do not know such technical subtleties and distinctive features of some pumps from others.

Overabundance of pumping equipment on the USA market, a wide range of cheap pumps, sometimes does not even have an elementary thermal protection, are pushing to buy a cheap pump. And in a short amount of time you are experiencing problems with repairs and service. It takes time, money, and who knows how long this pump will run until the next repair. Much calmer, pay once more, to get buy really high quality and reliability.

0013 model of Taco pumps

Buy now pump there is no difficulty: the shops and firms involved in trafficking of pumping equipment quite a lot. It only remains to sort out a number of questions: What pump for its purpose, its scope, design features and characteristics. After that, we can assume that you are ready to choose the pump that best meets the specific domestic goals.

Consider some of the technical details of the example pump company Taco, offering a wide range of pumping equipment to meet the needs of any customer such as: Taco 007, Taco 009, Taco 0013 and other circulators.

Thus, small portable pumps Taco in plastic made from corrosion-resistant materials and have a ceramic shaft, which ensures long-term operation and reliable operation of the pumps in aggressive water. The presence of plug connectors between the pump rotor and supply cables prevents the failure of the pump in case of suspending him for the Taco cable.

Pump rotor connection to the network

To connect to a network of Taco penciled him a wire or cable is cut and attached to the ends of the excretory or terminal screws in the inlet box. Some types of pump rotors have the box for fixing and commissioning of cables, steel pipes, metal hoses and other cable carve and finish steel pipes, flexible metal hose, etc., outside input boxes can not, because the ends of wires or cables in this case will be protected and can be damaged. Explosion-proof Taco pump rotors are connected to the network by entering into a box of wire and cable cross-section of 25 mm2 with a rubber or paper insulation.

If you connect a cable, whose cross section greater than 25 mm2, in front of the pump rotor install a special adapter box, which operates cable preparation. Wires and cables with a single-current-carrying conductors attached to the terminal screws of the Grundfos pump rotor directly to the inlet box (using bent at the end of the vein rings), and the wires and cables with stranded conductors supplying tips, fixed on the veins pressing or soldering. Tip and ring wear on the screws, opening the box and tighten the two nuts and washers, making sure the reliability of mounting screws and contact the correct jumper settings, connecting pump rotor windings in a star or triangle, depending on the rated voltage of the pump rotor and the network. Then the inlet box closed with a lid or cover to avoid accidental touching of naked, although isolated, conductors, and also keep water and foreign objects on them.

Grundfos pumps

The operating principle of the volume-the inertial pumps with electromagnetic vibration actuator based on the use of electromagnetic waves transmitted by the valve-fin. At the maximum pressure up to 40 m delivery pump is 1,5 m3 / h. Their capacity to 250 Tues
Electromagnetic Household Pump "The Kid" is designed for lifting water from tube wells with a diameter of 100 mm. When the pump must be completely submerged in water. Mono-space NEB-1/20 pump is designed for wells with a diameter of 200 mm. These pumps are powered by single phase line voltage of 220 V. The time of continuous operation up to 2 hours, followed by switching off for 15 ... 20 min.
Vibrating pump «Taco» raises water from a depth of 20 m, and Grundfos 15-42 F - from a depth of 40 m. The pump " Grundfos UP15-42B5" in its parameters is not different from the pump, "
Grundfos UP15-42FR
". Pump power «Taco» 300 W, flow 0.5 m3 / h.

Taco 006 - high-pressure pump

These pumps are typically multi-stage. Intensity of the pump depends on the size of the impeller, and other factors. Head in Circulating pumps of high pressure is achieved by using multiple impellers installed in series. Kinetic energy is converted into pressure in the working part, and partly rectifying apparatus.

Due to the possibility of varying the number of stages Taco 006 pump high pressure develops a higher pressure than low pressure single stage Circulating pumps.

Some pumps are up to 20 degrees. Thus, they can provide pressure up to 250 m. Almost all of the Taco 006 pump pressure, which we have described belong to the family of Dry pump rotor. Nevertheless, in recent years manufacturers successfully equip their engines with wet rotor.

Special instructions for block pumps
• Block pumps should be installed on the respective bases or brackets.
• Installation of block pump, at which the pump rotor and terminal box facing down, is not allowed. All other mounting methods are considered acceptable.
Detailed information on how to install, see the instructions for installation and operation.

Circulating pump: Types of installation

Permissible mounting methods

• In-line pumps are designed for horizontal and vertical mounting directly to the plumbing pipeline.
• To remove the pump rotor, the pump elements is sufficient space.
• When connecting the plumbing pipeline to the pump should not be given voltage and weight plumbing pipeline, a pump must be installed on the support (if any).

Improper installation

• Installation at which the pump rotor and terminal box facing down, is not allowed.
• If the power of the engine exceeds a certain level, before installing the pump in a horizontal position should consult with the manufacturer.

Mechanical seals


The basis of design of the mechanical seal are two rings with carefully polished surfaces. They are pressed together by a spring, and work together. CTS are dynamic seals and are used for sealing a rotating shaft in a fluid at high operating pressures. Grundfos is composed of two highly polished wear rings (for example, silicone or graphite), which are pressed together by axial forces.

One ring (dynamic) rotates with the shaft, while the other ring (static) still fixed into the body. Between the sliding surfaces a thin film of water that serves as lubrication and cooling. Depending on the mode of operation of the pump are several possible types of friction mating surfaces: a mixed friction, boundary friction or dry friction, the latter (which occurs at no lubricating film) causes environment destruction of the surfaces.

The service life depends on operating conditions such as composition and temperature of the working fluid.

Mechanical Seals

The materials for seals use high quality yarn from synthetic fibers such as Kevlar ® or Twaron ®, PTFE, porous graphite yarn, yarn of synthetic mineral fibers and natural fibers such as hemp, cotton or ramie.

Material for the seals is available in the form of threads or compacted coils in dry form or with special impregnation depending on the destination. If the material is purchased in the form of threads, you must first form a ring and give it shape. Then, the ring gland is wrapped around the pump shaft and tightened using crimp sleeves.

Circulating Pump Installation

In installations where the level of fluid intake is below the axis of the circulator pump used to fill in two ways:
1) in aggregates of a small filing with the diameter of the suction pipe of 250 mm at the end of her under the water level have a foot valve. In this case, make the filling through a funnel and a crane at the top of the pump casing from the PEX Plumbing system or special filler tank;
2) in the aggregates with d> 250 mm receiving valves do not put produce and fill with suction air from the pump is a special expansion pump (commonly used types of Grundfos pumps and Taco, creating a expansion to 97%).

If there is contamination of the liquid intake funnel on the suction tube is combined with a slit or a strainer. Control over the operation of the pump is over the testimony of the gauge and pressure gauge attached to the suction by the discharge nozzle, flow measurement is made on the flow-meter mounted in the pump discharge line.

So how about a load of the pump can be measured by manometer readings, are often reluctant to install meters on each pump and have a meter on the common plumbing pipeline, controlling for his testimony filing unit as a whole. As the flow meters are used diaphragms, Venturi tubes and wing water meters. Power expended by the unit, is determined by the voltmeter, ammeter or wattmeter, disposable on an Taco board assembly cli install.

To start the pumping unit should produce preliminary tasks: to ensure free rotation of the shaft, check the tap and manometer gauge, fill pump and suction pipe, open the flow of cooling water into the bearings (in units with a cooled bearings), to check the position of the oil in the bearings (at bearings lubricated). Valve on the discharge plumbing pipeline Circulating pump during start-up must be closed (for n <250 br="">

Start the pump is as follows: turn on the motor and speed it is brought to normal, slowly open valve on the pump discharge nozzle to achieve the required filing date; open valves that lead to the cooling water pump seal. When the pump should monitor the temperature of the bearings and the motor housing, which under normal circumstances should not exceed 60 ° C, the presence of oil in the chamber bearing (with oil lubrication), the density of glands (tightening of the packing is considered normal if he misses a few drops of water and temperature it is low).

Stop pumping unit is closing the valves on the discharge pipe, turn off the engine, close the valve on the suction tube and the cooling off seals and bearings). Start, the service at work and stop assemblies considerable power necessarily governed by special instructions. Special instructions subject to the exploitation of nutrient pumping units of steam boilers and pumps for hot liquids.

With modern technology development of automatic process control automation of pumping units is not difficult. Automatic pump control provides the following operations:
1) preparation of pumps to start, is to monitor the position of valves and pumps filled with liquid;
2) starting and stopping of pumps depending on the flow required by customers;
3) Stop the pump at fault it and start another pump to replace a faulty;
4) protection against overheating, seals and bearings;
5) the protection of hydraulic pumps, it becomes impossible to start the pump, not filled with fluid.
In developing the scheme of automation and protection of pumps may be provided for the necessity of pumping unit for the intended program. Automation improves the efficiency and reliability of the pumping unit, reduces the number of attendants.

Practical advice for brass valve installation

The role of substance that fills the thermostatic element is very significant bellows with gas filling have a large ball valve. They provide the maximum increase in the working volume of the bellows, and therefore the working stroke the brass ball valve at 1 "C. So, for example, when the temperature is lowered by 1" with respect to a given at the thermostatic element of the cone valve RT with the gas filling will rise above the saddle higher than in the case of liquid, oil or paraffin. Increased stroke valve for 1 "deals, as is known, more precise control characteristics and the bandwidth of the ball valve, and also provides less plugging of the valve.

The design of RT for two-pipe heating systems should be able to produce a preliminary hydraulic setting capacity brass ball valve. This is due, firstly, providing engineers calculated the required pressure loss in the circulation loop for hydraulic linkage heating system. Secondly, with the possibility of quick and efficient adjustment of the system after installation, because in practice when setting up heating systems often need additional activities to address the deviations from the project or design errors.

History of the pumps

The invention pump dates back to antiquity. The first NA to suppress fires, which invented the ancient mechanic Ktesiby, was described in 1. BC. Oe. The ancient Greek scientists Heron from Alexandria in the book "Pneumatica", and then M. Vituviem at work "De Architectura". Simple wooden pumps with a through piston for lifting water from wells, probably used even earlier. Before 18. Piston pumps, compared with water engine used sparingly. In the future, due to increased water demand and the need to increase the height of its filing, especially after the steam engine, pumps gradually pushed the pumping machine. Requirements for pumps and conditions of their use became more diverse, so along with piston pumps began to create rotational, as well as various devices for feeding pressurized fluids. T., historically there have been three areas of further development: the creation of reciprocating, rotary and hydraulic devices with no moving working parts.

The rise in the development of reciprocating pumps. observed in the late 18 century. when their manufacture began to apply the metal and use the drive from the steam engine. Since the mid 19. Have been widely implemented in the production of steam direct acting piston pumps for this period include the establishment wing of pumps, a prototype of which is a piston pump with a circular cylinder is described by the French engineer A. Rammell in 1588 ("Le diverse et articiose machine"). Development of the theory of piston N. closely associated with the work of local scientists and engineers (C. Bach, G. Berg, AP Hermann, Shukhov, PK Khudyakov, I. Kukolevsky, AA Burdakov, etc.). Advances in reciprocating pumps have been widely used also in creating reciprocating compressors, hydraulic presses and other devices, but the piston pumps ranging from 20 to 30-ies. 20. Became markedly displaced from a number of areas centrifugal, rotary, etc.

Specialty pumps Grundfos

Another way of pumps began with the invention of the so-called rotary pumps

Another way of pumps began with the invention of the so-called rotary pumps, had one rotor, which were also described Rammell. Pump with eccentric rotor is the prototype of modern sliding pumps. In 1624 I. Leyrehon in the book "La recreation mathematiqae" described the rotatory rotor pump, which can be regarded as the prototype of modern gear pumps. Later came other varieties, and rotary pumps, representative of which is, for example, labyrinthine pump, already established in the 50-ies. 20. The first vortex pump, called the centrifugal self-priming, was proposed in 1920 in Germany, engineer S. Hinshaw, and then appeared and others species.

The idea of using centrifugal force, the liquid appeared in 15. Even Leonardo da Vinci and, apparently independently of it was implemented in the early 17 century. Blankano French engineer, to build a simple centrifugal pump for water, which served as a working body of the open spinning wheel. One of the first centrifugal pump with volute casing and the four-bladed impeller was proposed by French scientist J. Papen, who perfected the design previously known blowers "Hessians". In the late 19 century. When there were high-speed heat, and then electric motors, centrifugal pumps have wider application. In 1838 Russian engineer A. Sablukov established on the basis of his earlier fan built single-stage centrifugal pump, in 1846 an American engineer, Johnson proposed a multistage horizontal pumps, in 1851 a similar pump was set up in the UK patent Guinn (Guinn pump), in 1899 a Russian engineer VA Pushechnikov developed a vertical multistage pump for drilling wells up to 250 m. This pump is built in Paris at the factory Farcot (pump FARC), was intended for water supply in Moscow, had a supply of 200 m3 / h, the efficiency to 70%.

Third direction development of devices for feeding pressurized fluid combines several ways of creating pumps

Prototypes of the propellants, according to the testimony of Heron, already produced in ancient Greece (the device to dislodge from the vessel of water heated air or steam). The first propellant production facilities were proposed in 1698 by British engineer T. Severi steam pumping plant. This device can be considered a prototype invented in Germany in 1871 Hullem pulse meter, which took two cameras and operate automatically.

The idea of using compressed air for water expressed in 1707, Papen and other engineers, but little has been applied much later (20.) - In monzhuse and double chamber water pump replacement for water wells (design engineer VP Savotin, USSR) . The water under the pressure of the combustion products of liquid fuel has been implemented in the UK in 1911 NL Humphrey.

Fundamentally different way of water or oil from wells with compressed air or other gas was used in gas lift, which had been proposed in the mid-19 century. And later found a practical application.

With the invention of the Montgolfier in 1796 automatically acting hydraulic ram there has been another way of development of devices for feeding pressurized fluid whose operation was based on the use of water spray from time to time created by water hammer. In the future, have been proposed various designs of hydraulic rams.

One variety of pump-sets was water-jet pump, which is like a laboratory device was proposed by British scientist D. Thompson in 1852 and served for the suction of water and air. The first design jet apparatus employed engineer Nagel in 1866 (presumably in Germany) to remove water from mines. Later established various jet pumps in the form of water-ejectors, steam-water injector, and many other fundamentals of the theory of jet pumps were laid in Tseynera G. and W. Rankin for the 2 nd half of 19. And received a significant development in the 30's. 20. Thanks to research by American engineers and O'Brien Goslina and Soviet specialists LD Berman, K. Baulina, A. Lozhkin, E. J. Sokolov, N. Singer, and others later proposed hydro-pneumatic water pump for wells (VP Sirotkin, YS Surenyants), in a design which combined jet pump airlift and. One of the directions of development of pump-sets is the creation of magnetohydrodynamic pumps. The first of these pumps at constant current proposed Golden (1907) and Hartmann (1919) and pumps with alternating current - Chubb (1915). However, they have become widely used in the USSR and abroad, only in 50-60-ies. 20., Mainly due to the success of nuclear energy. T., equipment lifting and moving initially only the water, then oil and other liquids in every period mainly corresponded to the level of development of productive forces and production relations.

- Summer residents are very popular among domestic circulator pumps "Taco". The capacity of 0,2 kW and 0,43 m3 / h capacity enough to ensure the garden plot and a house with water from a nearby reservoir. Household vibrating pump differs from the circulator pump and the lack of engine rotating parts, which greatly enhances its mechanical efficiency. He has a small size, it is easy to use and capable of pumping water at a distance of tens of meters.

- Which Taco pump to use if you want more water for household use?

- Automate the process of plumbing from wells or shallow (5-7 meters) wells will help small pumping stations. This station is mounted on the same basis and a small pump, at 22-25 liters, a membrane tank (accumulator). I must say that the weight represented in the assortment MPO Wiring "pumping stations is around 12-22 kg, that is, it may well carry one person.

How to size Taco-007 pump?

The most important parameter characterizing the Taco-007 pump, is its capacity (m3 / h). This figure indicates how much water is available for a certain period of time with such a station. We presented a range of alluvial stations manufactured by "Grundfos" (Denmark-Germany), "Taco" and "Speroni" , "Leader" (China), this figure is from 2.7 to 3 9 m3. Rated power ranges from 0,55 to 1,3 kW. Products are represented in the product group N07 on the price-list company.

An excellent solution for a country house will be a system of automated water "fountain house" production company "Dzhileks. It includes a submersible pump, control unit, pressure sensor, pressure gauge, hydraulic accumulator and a filter. The system costs much more affordable foreign counterparts, has a protection against "dry run" and surges.

- If the water in the well, poor quality, and the shallow well has ceased to provide the right amount of water, many have to think about the drilling of deep wells. What pump should be used if the aquifers are at a level below 10 meters?

- There should consider the option of using submersible pumps. Our company offers downhole pumps manufactured by «Grundfos», «Sumoto» (Italy), "Promelektro" (Ukraine) and "Dzhileks" (Russia).

Features passes through the PEX Tubing constructions

When the device internal PEX tubing networks (radiant heating, hot and cold running water, gas, sewer and drains) used tubes of different strength and surface hardness of materials (steel, copper and various PEX).

Some of these pipelines are almost always located in the interior ceilings, walls, walls and foundations. For risers, for example, the length of this part can be up to 10% (the distance between the sexes of adjacent floors - 3 m and the thickness of the floors - 0,3 m). The above elements of buildings can be implemented as a solid (concrete, bricks, etc.), and a relatively soft (wood, plaster, sheetrock, etc.) of building materials.

In this context, the assemblymen domestic pipeline networks, the question always arises [1], which are connected with the omission of polymer piping through constructions:

* How will affect the long-term strength behavior of soft polymer piping it into direct contact with the element of solid building material;
* How will affect the strength of the direct contact element of soft construction material to the pipeline of solid material.

Individual heating systems with Tankless water heater Takagi JR

Individual heating has long been common practice in Europe. Such popularity of individual heating systems is well founded. The main reason is that this method of heating rooms at least 2 times more efficient than the system of collective public services. Wall mounted gas tankless water heaters allow consumers themselves to regulate the temperature in the apartments, turn off the heat for prolonged departure or during the summer. This reduces gas consumption and save money.

Now individual heating actively developing in Japan. It's no secret that our country is central heating in some regions no longer operates. The introduction of individual heaters can solve this problem. This practice already exists and is constantly expanding. Here are some examples.

As the benefits of domestic tankless water heaters in the Voronezh region has been able to see about three thousand families. It is so much home "mini-tankless water heater" is set in the apartments of Voronezh for the 2002-2004 year. The program continues. About his participation in the implementation of high-efficiency innovation have 27 districts. In this case Semiluki and Talovskoye areas expected to be installed over a thousand domestic tankless water heaters, Takagi Tankless Water Heaters - about 700, and Stiebel Eltron Tankless Water Heaters - over 500. The total number of people wishing to transfer their apartments to individual heating close to six thousand. According to experts, the introduction of individual heating circuits can also make a much cheaper housing, because there is no need for expensive heating systems and heating units, as well as help to reduce tariffs.

Small city of Ogahawa region move to individual radiant heating. Thus, in Solonyanskom area of more than 70% of apartment buildings have already installed in their apartments needed gas equipment. Head of Housing Governor noted that this process is not under pressure from provincial authorities, as dictated by the need and desire of the population.

The effect of the introduction of the above systems is directly dependent on the quality of tankless water heater equipment. The most technologically advanced and reliable wall-mounted gas tankless water heaters developed by German company Takagi JR. Special attention should be a new series (Takagi, Stiebel Eltron).
