Regular hot water supply isa real headache for many of our compatriots. Worn out networks and frequent repairs lead to the fact that even in the middle of winter you can stay without hot water.
That's why electric cars are so popularwater heaters. Reviews about them are very diverse, and therefore we decided to analyze the most common, making the final conclusions about the advantages and disadvantages of this kind of equipment.
Judging by the reviews, fans of "protochnikov"especially impressed by their ability to instantly heat water. I came home, plugged the plug into the outlet ... and you can immediately wash or wash dishes! Agree, the cumulative models in this plan are much more complicated.
The fact is that in such heaters a powerful heater is installed, which can immediately heat the water passing through it even under the condition of decent pressure (in theory).
Among other things, flow-through devicesconsume a relatively small amount of electricity, because strictly required time is working. If we talk about accumulative varieties, they spend a lot of energy on maintaining the preset water temperature.
In general, the power range of the "protochnikov"varies from 5 to 27 kW. The reviews show that for the shower and dishwashing most often the device is enough for "modest" 8 kW. Such a water heater running electric, whose price starts from 2-3 thousand rubles, is available to almost everyone. That's only if you intend to splash in a bath that is filled from such a water heater, you need a 380 V network and specialists who will stretch it.
And on the last you should not save:wiring for such a powerful consumer should only be done by qualified electricians with normal experience, and not "Uncle Vasya" from the neighboring entrance, which once screwed the light bulbs in one of the numerous state-owned enterprises.
So for what purposes can electric water heaters be used? Reviews of people using them actually point to several areas of application.
In the latter case, the water heater is flowingelectric, the price of which is small, can serve as an excellent one-time "warmer", which is not a pity to send to the landfill after the completion of construction. Considering that in the evening and in the morning (when there is a need for hot water) the network on the object under construction is free, the wiring must endure.
Feedback in this case is positive, since it is the rate of heating water for domestic needs that is extremely important for builders.
What is still good electric water heatersflowing? The testimonies indicate that their other attractive feature is the compactness: such a device can be placed anywhere in the corner of a bathroom or kitchen, and it will be completely invisible. Compare this to the huge tank of a storage boiler!
Strangely enough, but on this basic waveenthusiasm ends. The fact is that the very principle of their work makes electric water heaters flowing unacceptable for many houses and apartments in our country. Reviews of people say that at best, before starting their operation, you will need to completely change the wiring, which is far from being affordable for everyone.
The fact is that for the most primitive modelyou need at least 5 kW, and if you want to wash not under a weak stream of water, but under a normal shower, it would be better to provide at least 10 kW. Needless to say, such an electrical network is not in every new cottage village.
In most villages, people generally do not think about buying flow heaters, since more than 3 kW of the local network does not hold.
The most positive feedback about those devices,which have electronic stabilization of water temperature. Since flow-through heaters raise the water temperature almost instantly, it is desirable to be able to fine-tune it, since otherwise, even burns are possible. Despite all the existing shortcomings, there are quite a few people who put up with them. After examining their recommendations, we would like to share with you tips on what to look for when buying a water heater running electric. Which is better to buy? Let's try to figure this out.
Consumers unanimously say that they should notbuy cheap Chinese models, whose electronic components rarely last for more than a year. In case of its failure you can expect a lot of not too pleasant surprises, down to rinse with steep boiling water.
Electric water heater of flow typeit is advisable to buy complete with a battery tank for water. The pages of the Internet are full of sad stories that tell of the sudden disconnection of water right in the middle of the "bath day." If you have at least a small reserve of water in such a tank, then you can wash off the foam. Of course, it will not be too pleasant to finish the procedure with the complete absence of hot water, but this is in any case better than "soapy races" around the apartment.
Thus, the ideal water heaterelectric for cottages. Of course, if you have the opportunity to make a separate tap from the meter, and also change the wiring to copper (if it has not changed for a long time). The testimonies testify that these devices are extremely useful, they "eat" relatively little electricity, and therefore are simply irreplaceable in some situations.
A huge plus is the fact that the scum on the TEN of such equipment simply does not have time to be deposited, so in maintenance, these water heaters do not need much.
Now you know what a running electric water heater is. How to choose the most optimal model that will fully meet your needs?
They cost in the range of 1600-2500 thousand rubles, thatmakes them affordable even for buyers with a very limited budget. The power of such models ranges from 2.5 to 5 kW, which allows them to be used in most apartments and rural houses without the need for major modernization of the wiring.
In addition, in this price category, you canto meet even a relatively good water heater running electric with a shower. However, customer reviews immediately warn that you should not flatter yourself especially: the head of the jet is so-so, and when you try to add it, the temperature of the water drops significantly. Pleasures from washing with cool water a bit.
Thus, if you want to have something moreessential, you will need a normal running electric water heater for the shower. Excellent models have proved themselves from THERMEX. Their cost is about 6-7 thousand rubles, which is not so much. As a rule, they are equipped with a mechanical temperature regulator, the power is within 5-8 kW.
In this case, all buyers already say thatit is highly desirable to replace the wiring to a more reliable one. In addition, consumers are advised to use the services of a professional electrician, since for such a power it is highly desirable to make a separate tap from the meter in order to avoid any sort of trouble.
Finally, flow heaters for continuous andunlimited supply of the entire house with hot water - saving on such a purchase is strongly (!) not recommended. The list of well-proven manufacturers is wide: Bosh, ELECTROLUX, THERMEX, LG ... Combines them one - exacting to the operating conditions.
Despite the power of 10-15 kW, the wiring shouldwithstand all 20 kW. The network is needed for 380 V. In addition, it is strongly recommended not to engage in self-assembly of this kind of equipment, as the consequences can be sad. In the conditions of rural wooden houses, it is undesirable to use such a powerful technique, as this is poorly correlated with the fire regulations of the relevant authorities.
In this case, it is better to purchase a more or less large storage boiler, which in this respect is much safer.
Having dealt with all the positive sides andrecommended manufacturers, let's discuss those situations in which the use of flow heaters is not only pointless, but also simply dangerous.
First, it is better not to buy them in casehot water you need regularly and in significant quantities, but even the meter in your apartment is designed for a maximum of 10-16 A. Similar occurs in our country often. You can put the heater at 3 kW maximum (!), Which even in the most optimistic case can provide you with only warm water for washing dishes.
We talked about the fact that flow models do nottoo sensitive to hard water. This is true, but if you have a muddy water with impurities running out of the tap, it will be better to buy an ordinary boiler. The situation in this case is not saved even by the filter: the testimonies indicate that the flow heaters are extremely quickly clogged with the smallest organic impurities, after which their heating elements fail. Replace them unrealistically.
In addition, if in your house there is at least oneThe articulation of aluminum and copper wires (which in itself is very bad), moreover, located close to the place where you are going to connect the "protochnik", the idea of its purchase is not too good. In this case, the probability of formation of a galvanic pair and destruction of the wire is likely, which will almost certainly lead to a fire.
Buyers of flow heaters confirm,that in the course of their operation cheap Chinese sockets can be heated to such an extent that their melting begins. Than it is fraught, you can guess yourself. So before installing such equipment, be sure to change not only the wires, but also other accessories, since it is not recommended to joke with such things.
In general, reviews about running electricwater heaters are of the same type. As a rule, buyers are attracted to the opportunity to almost instantly heat water, they really like their compactness and extremely low cost.
But almost all of them agree that inIn most cases, you have to pay a tidy sum for a complete replacement of the wiring and the installation of more powerful automatic machines. In addition, there is no water reserve (you can buy an additional accumulator), which is very important for rural areas and small towns where water supply disruptions are not uncommon.
Впрочем, проточные водонагреватели электрические, the price (reviews are also quite good) which are so small, quite deserve their part of the market as small and compact sources of hot water in case of its sudden disappearance from the tap.
In addition, no one will forbid you to combinetwo types of heaters: in the kitchen, put flow model, which is quite enough for washing dishes, and for the bathroom to acquire a large boiler, which additionally will play the role of a reservoir for water.
