Heat gas fuel can be classified in the first place, the type of burner used. Gas Tankless water heaters are divided into the atmospheric and fan. The boilers are equipped with fan burners, more stable work at a reduced pressure in the line, but have one major drawback – Gas tankless water heaters noise. Atmospheric burners operate virtually silently, but the boiler is manufactured in Europe with such a Takagi works properly only if the gas pressure is not lower than 150 mm. waters. Art. When the pressure is reduced to 130 mm. waters. Art. boiler gives out 85% of capacity, which, in itself, is not so bad. The problem is that at lower pressure gas flame, as experts say, “sit” on the burner. As a result, the burner burns with all its consequences. From Takagi venting parts do not, therefore, their use should be considered preferable, despite the increased noise. Note that US-made boilers are more adapted to our conditions (U.S. standards for gasification is much closer to ours than the European).

A few words about the device and a complete set of electric boilers
As mentioned above, electric boiler – a fairly simple device. Its main elements are the heat exchanger consisting of a tankless water heaters (Takagi), and a control unit and management. Electric boilers are available for certain firms have staffed circulating pump, expansion tank, safety valve and filter (for example, some models of the Japan company Takagi).
Importantly, low-power indirect water heaters are in two different versions – single-phase (220 V) and three-phase (380 V). Boilers over 12 kW are usually made only three phase.
The vast majority of electric boilers rated at more than 6 kW produced multi-stage, which allows efficient use of electricity and does not include the boiler at full capacity during the transition periods – spring and autumn.
When using electric boilers is most urgent rational use of energy. Significant energy savings can be obtained by installing remote programmer, which support the room temperature to a predetermined timetable. Incidentally the cost of such programmers is not high. For example, the retail price of weekly programming by British company Wester varies among different dealers around 50 USD. In addition to saving energy Programmers noticeably increase comfort and ease of use of heating equipment.
Do we need an expansion tank heating system and tankless water heater indirect heating
Durable tankless water heater Takagi country houses, cottages, commercial and residential, where there is no central heating and water supply, a serious problem installing specialized equipment to ensure the autonomous heating and hot water.
To solve the problem with heating facilities to small and large, you can use solid fuel tankless water heaters safe Takagi or a more efficient gas equipment. The main disadvantage of solid heating element (expansion tanks, heat transfer plates or other radiant heating equipment), is the high cost of consumables. The cost of firewood and coal, exceeds the cost of diesel or gas needed to create comfortable conditions in a residential installation. Another distinctive feature of the tankless water heater with solid fuel, is the lack of the ability to install sensors automatically feed fuel.
Also as a heating tool for heating and hot water in a dwelling can apply modern gas tankless water heaters floor. This kind of tankless water heaters for many decades of use as the primary source of heat and hot water, did not undergo specific structural changes. Heat exchanger element indirect water heater is of several types – iron and metal. Each species has its own advantages and disadvantages of a technical or construction plan. Metal pots are generally more resistant to external mechanical and physical effects, but at the same time, a metal pot less resistant to the corrosive formations. A major shortcoming of the metal pot is that when Misuse or improper installation and setup, often observed temperature drop below the “dew”. This means that the tankless water heater starts to collect the condensate, which is in effect and will be the main cause for the formation of corrosive coating.
Programmable thermostats for tankless water heaters
Takagi tankless water heaters with Lux Programmable Thermostats, with power, respectively, 16 and 28 kW, and the possibility of commutation. These tankless water heaters require separate wiring. Designed for one or several points of water pumping, for example, a kitchen and washing. The device is convenient because it does not require preconditioning water. With the help of the adjusting screw, you can even in winter when the temperature of incoming water is only 5C, get three liters of warm water per minute. But, in terms of comfort, low-power model is preferable for the summer time. In addition, it is recommended to replace the shower head at a more economical, with a small cross-section. The device can be installed anywhere in the transmission line, not necessarily close to the point of abstraction, so as not to violate the design space, corrosion-resistant copper and copper heater bulb will guarantee longevity.
Takagi tankless water heaters
Such equipment is relatively new. Takagi tankless water heater accidental called mini-water heater. In a small case of many models are not only a burner, heat exchanger and control unit, but one or two of the Circulator pump, expansion tank, pressure gauge, thermometer, and many other elements, without which it can not do work a normal water heater. Most of the Takagi water heaters equipped with devices to ensure safe operation. Thus, the sensor turns off the flame off the gas flame failure, locking thermostat switches off the water heater in case of emergency the temperature of water heater water, special devices for switching off the water heater power outage, blocking it at the gas cut off and reducing the volume of fluid below the norm, there is a sensor control traction.
By way of removing waste gas Takagi hung water heaters can be divided into a model with natural and forced draft. The latter have many advantages in the installation and operation, as exhaust gases are removed through the fan built into the water heater. They are ideal for rooms without a traditional chimney, as in this case the combustion products are derived through a special coaxial flue, for which is enough to make a hole in the Takagi. Coaxial flue is often called the “pipe in pipe”. In the inner tube of the chimney with the fan on the street displayed the products of combustion, and the external air is. In addition, these water heaters do not burn the oxygen in the room, do not require additional flow of cold air into the building from the street to maintain the burning process, reduce capital investment during the installation due to the replacement of expensive traditional chimney inexpensive coax.
Takagi Jr, Takagi T-K3-OS and T-K3-NG
Takagi water heaters are open, a series of “Takagi Jr“, or closed, a series of “Takagi T-K3-OS“, the combustion chamber. Closed combustion chamber allows the combustion gases are not in a vertical chimney, a device which is very expensive, and in coaxial horizontal chimney, directly through the Takagi of the house. This eliminates the need for a separate vent pipe on which the water heater must enter the air required for combustion of gas. This role performs the outer shell chimney. This design is called a chimney “tube in tube” and especially in demand in homes with Flats heating. When buying a water heater series “Takagi T-K3-NG“, coaxial flue supplied.
Burner, water heater «Solaris», due to the peculiarities of their construction is insensitive to fluctuations in gas pressure in the pipeline. At a nominal pressure gas 13 ICBMs, the water heater reliably at a gas pressure at the inlet burner 5 – 6 ICBMs. Power it while it is true, is reduced by 50-60%, but the wear of the burner is not increased. In addition, the burners in the water heaters modulating, ie intensity of combustion depends on the thermal performance of the water heater and the mode of heating and hot water. This property of the burner extends its working life and provides an economical mode of consumption of gas.
Most popular models of Takagi tankless water heaters
Takagi Tankless water heaters use the latest technology to provide the highest quality water heating appliances available in the market. These heaters do not require water storage and through this the supply of water remains continuous (which also depends on the fuel and the model type).

All the Takagi tankless water heaters except the outdoor models require pressure relief valve and the stainless steel venting (category III). In order to serve the easiest serviceability and the fastest installation, a tankless water heater valves is included in every Takagi model.
Tankless water heaters
Every summer has consistently for many citizens there is one and the same problem – disable the hot water. Hot water supply directly or indirectly associated with the huge and clumsy colossus centralized networks, aging with each passing year. So in the next 10-20 years, dramatically not solve this problem. Meanwhile, for individual families to solve this problem is to purchase savings elektro tankless water heater. Costs in this case would amount to only $ 150-200 with the delivery and installation – the price is comparable to the cost of the average mobile phone.
Selecting electrical water heaters (TAKAGI) is indeed enormous and can throw into confusion unprepared person. After all, in our market the products of more than two dozen companies – manufacturers of Japan, Europe, Asia and even America. The purpose of our publication – to help the reader navigate in this sea of information.
Key selection criteria cumulative TAKAGI bit: brand, size, dimensions, horizontal / vertical position, electrical power. Last but not least is the warranty period and price.
Let’s start with the volume and dimensions. It would seem simple: more internal volume – more than the external dimensions. But often, tankless water heater works on the intended purpose only month of the year, and all the rest of the time just takes up space, as a rule, already a small bathroom or kitchen. Some consumers tend to buy TAKAGI sufficiently large capacity. But do such a large volume? We recommend to pay attention to tankless water heaters volume of 50-80 liters. Stock up the hot water in them will be enough to take a shower, wash dishes. Surviving one month without bathing is not too difficult.
With regard to electrical power, here we must proceed from the situation. tankless water heaters of this class are usually equipped with heating elements (TENami) capacity 800-2500 Tues Do not abuse the increased power when wiring in the apartment shabby. Do not compare TAKAGI with iron, microwave and automatic washing machine: they consume more power from time to time, and TAKAGI may feel warm for hours. On the other hand, if the electrical network can connect 1,5-2,0 kW additional load, it makes sense to buy TAKAGI with a powerful Taine. In this case, the amount of TAKAGI may be less.
