The opinion of consumers about the devices "Termeks"
Many models of the presented brand do not have gaskets under the thermostat. As consumers note, this element can wear out quickly, and this should be taken into account.
If we talk about the advantages, then it is important to note the high power of the device. However, the parameter of the operating frequency does not exceed 25 Hz.
Mounting plates in instantaneous water heaters are installed the most common, and they can withstand average loads.
The blocks have thermal switches. Also, buyers note fairly high quality regulators. In general, the models of this brand are distinguished by their multifunctionality, and they have quite a lot of modes. Due to this, instantaneous water heaters can be safely called universal. A good model on the market will cost around 6 thousand rubles.
Which devices are more economical?
more profitable economically
But if the task is to purchase a functional device with high power in the house, then an instantaneous water heater with a boiler in this regard will surpass storage-type installations. The price tag for the latter largely depends on the material that was used in the manufacture of the tank. The cost is also influenced by such factors as the displacement, and besides it, the coating material for the inner surfaces of the tank. The design of the storage tank is also an important factor affecting the cost of the boiler.
Both devices, both flowing and storage, consume the same amount of energy. Some experts say that a flow-through water heater demonstrates a greater power consumption during operation. This is due to the fact that heating elements of higher power are installed in such installations. To check the truth of this opinion, it is necessary to turn to the laws of physics, which also apply in the case of water heaters.
Heating water in the amount of 40 liters to 45 degrees both in instantaneous water heaters and in storage-type installations requires the same number of kW. The thing is that in flow-through devices, although heating is done quickly, the power supply stops only after the tap is closed. In storage-type installations, it takes more time to heat water, but the heating elements installed in these devices have a lower power.
But at the same time, people using such equipment have the opportunity to use hot water for a long time. But given that the storage-type installation continues to heat water even if there is no need for it, it can be stated that flow-type water heaters are more economical.
How does a water heater work?
At the bottom of the device there are inlet and outlet pipes. They may differ in their diameter. Filters are located above the pipes. Next, a special anode is installed, above which the heating element is located directly. There is a special gasket under the thermostat. The mounting plate in the device is installed above the control unit.
Hot water is removed via a heat exchanger. The heating element probe is located near the flow sensor. Additionally, the water heater includes a housing, a power supply unit with a switch and thermal insulation sheets.
What is interesting about the Electrolux 35S model?
This instantaneous water heater for an apartment is unique, and its power is as much as 12 kW. He uses a steatite heating element. Thanks to this, the productivity of the device reaches as much as 4 liters per minute of use. The control of the instantaneous water heater is provided by a button type.There are three modes in total. The maximum user is able to set the temperature to 50 degrees.
The power supply is installed of a fairly high quality, and is absolutely not afraid of overloads. In this case, the parameter of its operating frequency is at the level of 25 Hz. The unit has a thermal switch. The heat transfer zone is quite extensive, and the thickness of its thermal insulation is as much as 1.5 mm. A protective gasket is provided under the thermostat by the manufacturer. Separately, it should also be noted the reduced noise level of this model. This was largely achieved through the installation of a high-quality casing.
According to buyers, during operation, the instantaneous water heater does not make practically any sounds. There is also no vibration. The Electrolux 35S installation is more than simple. The pipes in the lower part are standard, and they are suitable for the water supply system of the house. Fastening to plastic outlets is permitted. This instantaneous water heater costs about 5100 rubles in the store.
Flow-through heater: what is it
The main thing, than a flow-through water heater differs from a storage water heater is the process of heating water. In devices of this type, it occurs much faster, which is ensured by heating elements of higher power, which are installed in these installations.
Hot water starts flowing within 15 minutes. This is provided by flow sensors, the main task of which is to regulate the number of included heating elements. With a small value of the opening of the valve, a small number of heating elements are in the on state. As the pressure increases, the maximum number of heating elements is activated. A similar principle used in the operation of storage-type equipment makes it possible to minimize the cost of power supply.
Instantaneous water heaters ensure that the water heats up in accordance with the specified parameters. Thus, overheating of the water is excluded and the risk of burns to the owner is also excluded.
Note that instantaneous water heaters can be equipped with additional equipment - electronic control. All processes are reflected on the display. During operation, all important information will be displayed on it: hot water temperature, consumption and power of heating elements. If a malfunction occurs in the operation of the equipment and the temperature of the heated water has exceeded the set value, then the security system will warn about this by highlighting a special indicator on the display.
Installation features
The weight of the storage water heater is decent, so you need to make sure that the wall can withstand the load. The flow-through unit can even be fixed to a plasterboard partition.
In terms of connecting to the mains, the storage device needs an outlet. For the flow-through, an automatic machine is installed, the connection is made through the switchboard. Water heaters with a capacity of more than 9 kW will be connected to a three-phase network.
Water supply method
According to the method of water supply, the heaters are divided into pressure and non-pressure. The first ones cut into the water pipe riser and serve several points of the fence at once. The second ones are installed near the point of the fence and only serve it. Non-pressure water heaters are supplied with shut-off valves installed in front of the unit.
Service
The storage units will have to be periodically cleaned from scale and sediment in the tank. Water is an aggressive medium, so the magnesium anode, which protects the inner tank, needs to be replaced once a year. Experts advise installing a filter in front of a storage type water heater if the quality of tap water is low.
Flowing ones are better in this regard. If you correctly connect all networks, then during operation you will not have to approach it.
Appearance
Manufacturers make sure that their products have a presentable appearance.Therefore, it is difficult to say which storage or flow-through water heater is better in this regard. There is no point in comparing this criterion.
Criteria for choosing a device for heating water
After analyzing the water heaters, you can choose which one is right for you:
- If you need a device for heating water during a breakdown in a boiler room, then it is better to use an electric instantaneous water heater.
- Do you need a constant source of hot water in a large private home? This means that a storage gas boiler will do.
- If the apartment has old wiring, and you are not going to change it, and there is nowhere to put the storage device, then it is rational to use a flow-through device with low power.
- Any type of appliance chosen should be purchased from the best manufacturers that provide a guarantee.
Popular models from well-known manufacturers
Water heaters are produced all over the world in one quality or another and differ insignificantly in basic parameters. It is impossible to list everything within the framework of a short article, but there are recognized industry leaders whom it is impossible not to mention:
- These include the Italian manufacturer "Ariston". Its distinctive feature is its unswerving adherence to market demands and constant improvement of its products. The main product line is represented by storage boilers with a volume of 30-100 liters. The proprietary solution is the inclusion of silver in the inner coating of the container. Stainless steel and titanium are also used for their manufacture. The positive aspects include perfect electronic control using touch screens.
- The well-known manufacturer Electrolux is no less famous (in 2019 this manufacturer will celebrate its 100th anniversary). With the constant growth of the functionality of the devices of this manufacturer, they are always distinguished by high quality products. In modern models, effective pressure and temperature automation is installed.
To cover the inner surface, durable glass-ceramic is used, which, moreover, has disinfecting properties.
Most designs use twin heaters. This design saves energy.
The disadvantages of the products of this brand include, first of all, the high cost of products with a noticeable difference when compared, and the low service life of the heating elements.
The products of the Electrolux brand are distinguished by their refined elegance of execution.
- The products of the Slovenian manufacturer "Gorenje" are distinguished by their desire to follow the wishes of their consumers with high quality products. High quality enamels and stainless steel are used for the inner surfaces of the tank. A distinctive feature of these devices is a wide range of capacities and power. An effective control system is installed in the products of this brand to control all the main parameters of work.
- It is possible that the consumer will be interested in the products of domestic consumers. For example, an interesting water heater "Alvin", which in 40 minutes will warm 30 liters of water to a temperature of 70 degrees. The unit is housed in a 1 mm thick stainless steel case. The power of the heating element is only 1.5 kW.
The principle of operation of an instantaneous water heater
First of all, two main modifications of flow-through heating devices should be distinguished: gas water heaters and electrical systems.
Electric instantaneous water heater is a sealed container of small volume, inside which the heating element and the necessary sensors are mounted. The appliance is equipped with a control unit that allows you to adjust the leaving water temperature.
Water heating occurs almost instantly, however, it should be noted that even powerful models of flow-through heaters will not be able to provide a temperature of more than 60C.In addition, the degree of heating is highly dependent on the pressure in the pipes and the temperature of the water at the inlet.
Gas water heater was developed by German engineers at the beginning of the twentieth century, and, at present, has become quite widespread in everyday life and industry.
At the moment the hot water tap is opened, the gas burner is automatically ignited. Cold water, circulating in the coil of the heat exchanger, heats up quickly and flows to the distribution points. If there is no need for hot water, the automatic control unit cuts off the access of oxygen to the combustion chamber and the burner goes out.
Despite significant differences in design, the principle of heating water in an instantaneous water heater and in a gas water heater remains unchanged: rapid heating of incoming water immediately before consumption.
Features of instantaneous water heater
Instantaneous electric water heaters have a number of tangible advantages, represented by:
- compact dimensions, due to which the installation of a hot-water device is possible in the most convenient place;
- almost instantaneous heating of water to quite comfortable indicators;
- the presence of a regulating device that allows you to set the optimal temperature regime for heating water;
- the ability to choose the heating element presented by the heating element that is optimal in terms of power level and consumption of electrical energy;
- no need to equip the chimney system.

The objective disadvantages of such equipment include increased energy consumption, not always sufficient throughput, the need to allocate a household network with a minimum limit on the supply of electrical energy.
Instantaneous water heaters with low power indicators can be installed even in apartment buildings, but are most often used to heat water in a private household.
Features of the water heater "Termeks S600"
This instantaneous storage water heater for an apartment is appreciated by many buyers for its versatility. As mentioned earlier, the devices of the presented company have many different modes, and this instance is no exception. The user is able to select a maximum temperature of 50 degrees. The connections in this instantaneous water heater are of a standard size.
However, before buying, it should be borne in mind that it is better not to attach the device to plastic pipes. This is due to the fact that the clamps are installed quite rigid. In this case, the wear of the plastic outlets will be inevitable. This was noted by many masters involved in the installation of such equipment. If we talk about advantages, then a reliable protection system also deserves attention. It is installed in this case, type IP 30. Sheets of thermal insulation in the device are used with a thickness of exactly 2 mm. The heating unit for the "Termex S600" model has a copper one. This instantaneous water heater for an apartment costs about 5800 rubles.
Water heaters in the apartment
In any private house, along with autonomous heating and sewerage, a water heating system is also installed. But it can also be useful for residents of apartment buildings. In the summer season, utilities are engaged in the repair and adjustment of equipment in the boiler room, therefore, interruptions in warm water are a story familiar to residents of high-rise buildings from different cities. For this difficult period, it would be nice to have your own water heater.
The water heater can be installed both in a private house and in an apartment
Standard device requirements:
- profitability of use;
- the ability to provide the desired boiling water for a bathroom, shower, sink and toilet.
Storage and instantaneous water heaters meet these requirements to one degree or another.But to understand which device is right for you, you need to understand the strengths and weaknesses of the two devices.
Efficiency of using an instantaneous water heater
Instantaneous water heaters are more compact. They can be installed in any place and, if necessary, can be easily dismantled. Apartment dwellers prefer flow heaters precisely because they take up little space.
However, there is a hidden danger here. In contrast to the storage device, the instantaneous water heater has a high power from 3 to 24 kW. This means that additional security measures are required during its installation. Such as: installation of an additional machine, and, if necessary, replacement of electrical wiring.
The principle of operation of the flow-through device also consists in heating the heating element. But more powerful heating elements are used here than in boilers. Water, passing through the heat exchanger, heats up quickly (from 30 seconds to 1-2 minutes, depending on the model), so the devices are often installed in kitchens and summer cottages.
Instantaneous water heaters take up little space and are quite efficient. The only drawback of the device is the significant consumption of electricity.
