Most of us in everyday life is required hot water. Unfortunately, utilities can not always provide its presence, so you have to think in such cases how to provide yourself with hot water. The most popular solution to this problem is the installation of an electric water heater with a cumulative tank
Cumulative electric water heater (in use of a boiler) is a household device capable of heat water in a special capacity to a temperature of 55-80 s and maintain it automatically. Many attracts simplicity of installing such devices, because they can work from the usual outlet. The flowing water heater is so easy to connect, since it requires high power. Sometimes the accumulative models are used even in gasified houses. The fact is that the installation of the gas column is expensive and legally troublesome measure: it is required to obtain permission in the service of the gas economy, chimney and ventilation are needed. Therefore, if homeowners have no alternatives, they are forced to put up with the lack of design of cumulative models. They have amines: they occupy a lot of space, they are expensive, slowly warm water (TEN with a capacity of 2.5 kW approximately for 3h heats water from 20 to 75 s in a 100-liter tank).

Do not make mistake
First, decide on the volume of the water heater, which is selected depending on the tasks set before the equipment. For kitchen needs, models with a small tank capacity of 5-10l are usually used, it is usually enough. The device with a tank for 15-30l is suitable for a washbasin, and for 30-100l and more for the bathroom and soul (it largely depends on the number of tenants and, of course, from their love for water procedures). It is considered (very conditional) that 30-50 liter of hot water from the tank is consumed for a single reception of the soul (here and then there is a water, heated to a very high temperature, for example, up to 80 s, and when mixed with cold water, a total final volume Water with a comfortable temperature of 38-40 C is obtained in two large). Single people and families of two people usually choose a boiler for a bathroom with a tank for 50-80l, a family of three to four people with a capacity of 100 liters and more. Here you have to take into account, on the one hand, the desire to have a greater supply of hot water, with another possibility of placing a fairly bulky equipment in the bathroom. One thing is a compact 30-liter model, and a completely different - 150-liter "barrel", which also takes a lot of space, and weigh so much that not every wall will endure it (50-60kg technology plus 150l water).In the market there are heaters, the design of which is designed for wall and floor mounting. Connapoles usually include high capacity (150-300l). Wall mounting is provided for boilers of up to 200l.
The efficiency of the device depends mainly on the quality of thermal insulation of the tank. Proportion, spacious units may even more efficiently, especially if heated water at night (with a valid preferential tariff). Daily heat loss in models with good thermal insulation tank with a capacity of 80-100l are 0.8-1.2 kWh. This means that to maintain the water temperature at a given level (usually 60-65 c) with a full tank, a water heater requires about 1 kW h per day. Accordingly, for 1 h With this operation, the technique consumes an average of 40W. Hospital, this most important indicator is reflected in the description of products not all trademarks. Such information provides, for example, AEG (the indicator is indicated as "current consumption in readiness mode / 24h"), while Ariston is "thermal losses at T = 60 C", and in the Timberk documentation - "heat loss,% per hour "
As for the power required for the connection, most models are laid in the range from 1.5 to 2 kW. Less undesirable heating will be too slow, but also it is impossible because of the long load on the network.
How to care for machinery
Maintenance should be made by a qualified specialist, but its services will cost at least 1500 rubles. Once a year, the internal cavity of the tank, TEN, is observed, the state of the magnesium anode is estimated. Details should be cleaned from a lime deputy resulting due to stiffery salts. Magnesium anode is replaced with strong wear. Usually it is supposed to be changed once every 1-2 years, so check when you buy, where you can purchase a detail for replacement and how to carry out this procedure. In general, the problem of replacing the resulting anode can be very relevant, so manufacturers offer their own extension of its service life. Available, for example, water heaters with non-replaced by a titanium anti-corrosion anode connected to a current source (current overlapping). Such models have, for example, from Stiebel Eltron (SHZ series).
Features of devices
Handling or pressure? The absolute majority of boilers are designed for operation at operating pressure of water from 0.5 to 7-8 bar. This allows you to embed them into the water supply system, supply hot water into several waterproof points. There are also non-pressure heaters, in which water flow overlaps at the input (after filling the tank). These are small volume devices (usually 5-15l), simple design and inexpensive (on average 3-6 thousand rubles). They can only be used for one point of water treatment (more often in the kitchen). The like MS (THERMEX), BTO (DRAZICE), SNU (Stiebel Eltron), O'Pro Small (Atlantic) include citive.

Horizontal or vertical installation? Design devices are made for mounting in a horizontal or vertical position, as well as in any of them. The choice depends on the availability of free space. For example, boilers with horizontal tank are often located above the doorway. Most heaters are released in both modifications. If you are not sure which one of them will probably be a win-win solution to acquire a universal model that can be mounted in any position. Timberk (RE4 VH series), Electrolux (EWH Centurio Digital Series), Stiebel Eltron (PSH 100 Universal EL).
Additional modes of operation. This is, firstly, the water heating mode (provided in the models of a number of German producers). It provides automatic inclusion of the heater in the range of low electricity tariffs. Secondly, half-power modes and accelerated heating, which are involved, respectively, one or two tanks, thirdly, frost protection mode. We will automatically turn on weak heating when the temperature is reduced to a certain limit.
Why are the water heaters fail?
Most often, the technique breaks down due to the combustion of the Tan, for example, when forming an insoluble precipitate on it - scale. It is actively formed at temperatures above 60 C, so if the water temperature is maintained below the specified value, this will reduce the rate of scale of scale. The installation of the device can help the installation of the magnetic converter of water rigidity on the cold water supply pipe, as well as the prophylactic cleaning of the Tan.
Electronic control system and smart functions. Computerization often makes the operation of water heaters more convenient. For example, in the EWH Formax DL (Electrolux series) models implemented Multi Memory technology, which allows you to individually program the operation of the device, installing in its memory to three different water heating settings in its memory. It remembers the "favorite" user temperature, which can be selected without additional adjustments using the mode setting button. Eco Aqua and Smart Shower are acting differently in Haier models. The first allows the water heater to automatically track how you use it during the week, remember it and adapt to your needs. For the second, you need to specify the number of family members, and the device itself automatically sets the upper limit of water heating temperature.
In cases, the electronic control system is equipped with a liquid crystal display, which is derived from the current operation, water temperature and other information. Some models of water heaters, such as FS6 (Timberk), are also equipped with a remote control.
Tan design. For water heating, commonly used widespread in everyday life. In addition to classic submersible, there are so-called dry lands, they are characterized by high durability (service life is 3-4 times more), noiseless when working and do not overgrow. In addition, they are very easy to replace - you can simply turn out of the tank, without even merging water out of it. Dry Tan water heaters are produced by Atlantic, Stiebel Eltron and Gorenje.

Due to what will save?
The price of the heater largely depends on the volume of the tank, the material of the housing used by the automation. Cheap models for the kitchen with a capacity of 10-15 liters like EWH 10 Genie O (Electrolux) can be bought in 4-5 thousand rubles. The device of 30-50l will have to give 7-15 thousand rubles, and 80-100l15-20 thousand.What can save on? First of all, due to the shape of the body. Models with a cylindrical housing are cheaper than "flat" (flattened in depths), with other things being equal in technical characteristics. You can also save on the case material (but not a tank). Traditional water heaters with an enameled cylindrical corps are likely to look not so stylish as made of stainless steel, but at proper operation will also serve no less.
What does not save on? On devices that ensure safe operation of equipment, for example, on a protective shutdown device (UZO). According to the rules, all the devices located in the risk area of N 2 (no further 60cm from the edge of the bath) should be equipped with a 10 mA cut-off current. Residently models of the Uzo can be built-in, and in its cheap, most likely, no (do not forget to ask the seller about it). If the Uzo is absent, then you will have to spend on its acquisition of 500-1500 rubles. The same applies to the so-called security group, which includes a safety valve (from overpressure in the tank) and a check valve that does not allow drain of water from the tank when theft falls on the network. If there are no security groups in the kit, it will have to be purchased separately (approximately 1500 rubles), it is impossible to operate the device without it. Also, it may be necessary reduced pressure reducer if it exceeds the allowable (usually 0.6-0.7 MPa or 6-7 atm).
All on the fight against the smell!
With long downtime, water from the heater is recommended to merge. Therefore, the installation of the device must be manufactured so that it is available for this. If the water in the boiler tank has acquired an unpleasant smell due to long stagnation, it will need to be rinsed with water heated to the highest possible temperature (but not less than 70 seconds) to destroy microorganisms. We are much more convenient than the model with a built-in system for suppressing the livelihood of microbes (this may be, for example, the inner coating of the tank with silver ions). Water in such a tank will not bloom and will not turn.
We establish according to the rules
Decide with the location of the boiler. According to GOST R 50571.11-96, place this device should be placed at a certain distance from the bath and washbasin, depending on the degree of its moisture protection. Most water heaters correspond to the degree of protection of the IPX4, therefore, they can be installed at any convenient distance from the edge of the bath, a toilet bowl or shower unit. The plug socket for it should be located not closer to 0.6 m from the edge of the sanitary exercise, have protective curtains, degree of protection of at least IPX4 and be connected through a distribution transformer or UZO, and also properly grounded. There are many nuances, to observe all the rules is vital, so the connection of the boiler should be carried out by an electrician.Opinion of a specialist
In the absolute majority of cases, water heaters are installed in the bathroom or kitchen, that is, in rooms with high temperatures and humidity. Consequently, all non-metallic components should be resistant to thermal overloads, not to maintain burning, and the entire device as a whole is to have a high degree of protection against lesion. In addition, the device should not just warming the water, but also not to have a negative impact on its quality. Therefore, it is especially important that in the composition of the enamel of the internal surfaces there was not even potentially harmful elements. The inner coating of the tank should provide a high level of protection of the entire structure from corrosion and ensure the strength and durability of the water heater.
