Detailed instructions for using a Thermex water heater with a volume of 15, 30, 50 and 80 liters

Termex electric water heaters are manufactured using high technology and quality materials. Such water heaters are equipped from the factory with a safe shutdown function (RCD), which increases the level of safety of the device.

Such devices are manufactured according to international standards and meet all safety and environmental requirements. These devices must undergo state certification and meet GOST standards.

Electric water heaters of the Termex model range differ in their characteristics and the volume of internal space, which can be 15, 30, 50, 80 or more liters, and in this article we will talk about a Termex water heater with a volume of 30 liters, and we will also consider detailed instructions for using this models.

In fact, the Italian electric water heater is a design with a tank, in the inner part of which there are heating elements, in other words, heating elements. The larger the volume of such a tank, the greater the amount of water it will be able to heat to the required temperature. 30-liter water heaters are perfect for a small apartment, small house or construction trailer. This volume will be quite sufficient for domestic use. This model is very economical and practical to use, and its cost is not at all high compared to similar versions of other models. Such devices do not require special installation, as they operate from a regular outlet.

The Italian company Termex produces water heating devices of excellent quality and various internal tank volumes: 15, 30, 50 and 80 liters, respectively. According to customer reviews, 30-liter water heaters can last more than ten years without problems, of course, if you follow certain rules for servicing the device.

Main technical characteristics of Termex 30 liters

As with most appliances powered by electricity, Thermex 30 liter water heaters require a voltage of 220V (an error of +/- 10% is allowed), with a frequency of 50 Hertz. The capacity of the internal tank is 30 liters. The inlet/outlet thread size is 1/2. A device with a capacity of 30 liters heats water in no more than 50 minutes.

Thermex kit includes:

• The water heater itself with RCD
• Safety valve RSD, one piece
• Directory
• Special mounting anchors, four pieces
• Package

Safety rules during operation

The following rules, which are stated in the operating instructions, must be observed.

• Connect the device to the power supply if there is no liquid in the tank.
• Try to remove the protective panel while the device is connected to the network.
• Use the EWH when it is not grounded.
• Use the device when the water pressure in the main line is more than 0.6 MPa.

• Use water that has passed through the EWH for cooking.
• Use spare parts that do not meet the recommended technical specifications.
• Use water that contains sand or other particles.
• Change the fastening design.
• To extend its service life, it is strongly recommended to clean the tank, followed by changing the protective anode once a year. And if you have very hard water and the device operates constantly, you need to do it every six months.

Taking water procedures:

• Connect the device to the network
• Set a comfortable temperature. Depending on the device you use, mechanical or electronic, there are two ways to adjust the water temperature.

  
  Heating temperature adjustment

For example, in the thermex bio glasslined line, the temperature is adjusted by rotating a mechanical relay, while in thermex stainless g.5, to set the temperature, you need to press the up arrow on the display and hold it until it reaches the desired value.

The optimal heating temperature is 45-55 degrees; this range will protect the heating element from plaque formation. Also in this model it is possible to use an economical mode using one heating element.

• Wait until the water heats up.

Rice. Storage water heater THERMEX IS 50.

Any new equipment, even the most simple one, arouses some creative curiosity among non-specialists. The subject of study, this time was an electric water heater.

This week, at the end of the working day, they brought an electric storage water heater, specifically THERMEX IS 50 2011. Electronics specialists surrounded the miracle device with curiosity, and... the production process stopped for almost an hour - everyone was carried away by the new toy. Despite the simplicity of the breakdown, the lack of experience in working with such devices somewhat delayed the diagnosis.

A brief description of the operating algorithm of an electric heater ; we admit that some conclusions are erroneous, as they are based on subjective conclusions.

Rice. Operating principle of storage heater

The hot water outlet tube is located at the very top of the tank, the cold water supply tube is located at the bottom. Hot water collects at the top of the tank and is taken from there by the top tube; the pressure in the heated water tube is carried out due to the pressure of cold water. Purely theoretically, the tank should not be empty, since the intake tube is located at the top of the tank, but there is a chance that water can escape through the inlet.

Safety.

The study, as well as diagnostics and repairs, began in order.

First of all, we checked the power elements for breaks; both heating elements were not broken.

The emergency thermostat, despite external damage, works, the error is less than 10 degrees C. The thermostats were checked with a hairdryer, the sensors were heated to the required temperature and the operation of the thermostat contacts was monitored. The simple circuit with a minimum of control elements could not be repaired; the presence of a capacitance between the housing and the filaments of the heating elements was confusing.

Rice. A visual inspection quickly revealed the problem.

Logically, there shouldn’t be a capacitance, but there was, and we couldn’t find an explanation for this until we visually saw the heating elements, one of them exploded and formed a capacitive connection with the body. It was not possible to find heating elements on sale at an acceptable price, so after minor modifications to the heater and circuit, only a small heating element was left, which, in principle, did not significantly affect the overall operation of the heater.

Instantaneous water heater Termex System - a closer look at the device

Characteristics and operating principle

The outer casing of the device is made of high-quality material, and the inner part is made of stainless steel combined with titanium, resulting in high resistance to rust and durability of the device.

The remaining space between the body and the internal tank is covered with a special sealed material (polyurethane foam); this is a very environmentally friendly and modern method of thermal insulation.

There is a temperature sensor on the outside of the case. Water is heated thanks to heating elements located inside the tank, the temperature of which is controlled by a thermostat. The thermostat will maintain the set temperature.

For safety, water heaters are equipped with a function to automatically turn off the device when the maximum permissible temperature is reached - 95 degrees.

Which water heater to choose - storage or instantaneous?

If you decide to approach the issue of heating water thoroughly, then it is better to go to the expense and choose a storage water heater.

We planned to go swimming and wash the dishes in an hour - we turned it on, washed and shaved, and turned it off. And the water will cool for a long time (several hours), it can be used without consuming electricity.

If you need hot water here and now, or are limited in funds, or have nowhere to put this huge tank, then, of course, it is better to choose a compact, instantaneous water heater. But here you need to take a special approach to the power supply, which will be discussed below.

Safety instructions for working with a water heater

To achieve the required level of safety, the device must be grounded in accordance with current regulations for the installation of electronic devices.

When installing a water heater, it is prohibited to perform the following actions:

• You cannot connect a water heater to the network without first filling it with water.
• It is not permitted to dismantle the equipment while it is in operation.
• It is forbidden to use the water heater without grounding
• Do not connect the water pipe to the water heater without using a safety element
• When connecting the device, the pressure in the water supply system should not exceed 0.6 MPa
• You cannot use for installation of equipment those elements that are not included in the kit.
• The water in the system must be clean, free of impurities and other heavy elements that may adversely affect the operation of the device.
• The water from such a water heater is not food grade.
• Drain water from the water heater only when the power is turned off.

Finding the cause of the breakdown

Before you begin repairs, you need to find out what is causing the problem.

This can be understood in advance without disassembling the device itself.

The main malfunctions of electric water heaters are:

• the device does not turn on;
• short circuit protection (RCD) is triggered;
• the water heater does not heat water or does not comply with heating standards;
• boiler leaked.

If a leak appears, you need to find out where the leak is. If it is the heating element gasket that has leaked, then such a defect can be easily eliminated. You just need to replace it with a new one, especially since they cost pennies.

You can find out how to make the right choice of water heater and not make a mistake here: https://teplo.guru/vodonagrevateli/ariston-termeks-elektrolyuks.html

You can first understand that it is the heating element that has failed by the following indirect signs:

• automatic protection is triggered;
• knocks out the machine on the meter;
• the water does not heat up, or the device does not heat well;
• the hissing of the water heater and the release of water with a cloudy consistency and an unpleasant odor.

With such symptoms, the heating element is most likely to fail. This can also be determined by the appearance of the heating element itself - the shell is damaged.

Sometimes heating elements burn out without visible damage to the shell, then this can be determined using a tester.

If the ohmmeter shows infinity at the terminals, then the nichrome spiral is broken.

If it is zero, then there is a short circuit somewhere. In any case, such an element needs replacement.

In some cases, the heating element fails for the following reasons:

• The heating element has served its term;
• the unit was turned on without water;
• the water heater was turned off for a long time, but the water was not drained;
• sudden changes in voltage in the network.

In any case, the heating element needs to be changed. Of course, the easiest way is to use the services of a specialist, but it is quite possible to change the heating element yourself. It is necessary to warn that repairs must be done in a certain sequence to avoid confusion. This is an important key to successful repairs.

Instructions for installing and connecting the device

The installation and connection of the water heater must be carried out only by a qualified specialist, otherwise it may malfunction and cause physical and property damage to health.

Placement and installation of the water heater

It is important that the location of the water heater is close to the place where hot water is used, this will help reduce heat loss when passing through the pipes.
The water heater is attached to a special housing bracket using pre-hammered anchors.

In the room where it is planned to install a Termex water heating device, there must be waterproofing of the floor and an outlet to the sewer. It is not allowed to place electrical appliances and objects that are “afraid of water” under the operating device. If such conditions cannot be met, it is necessary to at least install a special protective pan with access to the sewer. Termex kits with tank capacities of 15, 30, 50 and 80 liters do not have a protective tray.

Electrical connection

Before connecting the water heater to the electrical network, it must be completely filled with water.
The device comes with a standard cord and plug for connecting to the mains. The outlet must be modern (with a grounding terminal) and located in an area protected from humidity. In this case, you need to take into account the maximum permissible power for the socket and cord, which must be more than two thousand watts, otherwise the wire or socket may overheat and a fire hazard may arise.

Do-it-yourself Termex boiler repair

Before you begin the repair, first gather the necessary tools: a set of wrenches, an adjustable wrench, electrical tape, various screwdrivers, pliers. After this, turn off the water by closing the inlet and outlet valves to the water heater. Then drain the water from the boiler tank and disconnect it from the power supply .

The next step is to remove the protective cover. If you have a vertically located boiler, then the lid is located at the bottom, and in the case of a horizontally located one, it is on the left or in front.

When removing the cover, pay attention to the stickers. Often the screws for securing it are located under these stickers. If you have unscrewed all the screws and the cover still does not come off easily, check the stickers again.

Replacing the heating element

First, perform all of the above steps and remove the tank cap.

To make it more convenient to work, you can even remove the tank from the wall.

It is worth noting that most Thermex models have not one, but two heating elements. Therefore, it is imperative to remember how and in what sequence the parts need to be connected . It’s better to photograph the whole process.

To remove the heating elements from the Thermex water heater, remove the top cover by unscrewing the bolt; disconnect all plugs and unscrew the bolts securing the heating elements.

The heating element itself is turned off as follows:

• After removing the cover, find the protective thermostat, remove the tips from it;
• also remove the tips (3 pieces) from the heating element;
• cut the plastic clamp;
• Unscrew the screws, removing the sensor;
• now disconnect the cable and unscrew the four screws;
• then you need to dismantle the nut on the clamping bar and pull out the heating element.

After dismantling the heating element, it is necessary to clean the surface of the tank from dirt and scale. Only after this can you install a new heating element and put everything back together.

Do not forget that the heating element does not always need to be changed. If the water in the tank still heats up, but it happens slowly, then, most likely, scale has formed on the heating element. Then dismantle it and descale it. Then install. The problem should go away. Also, do not forget that it is advisable to clean the heating element with chemicals rather than scrape off the dirt. In the latter case, there is a possibility of damage to the part.

To clean the heating element, you can use a solution of citric acid or vinegar (its percentage in the solution should be about 5%). The part must be immersed in liquid and wait until the scale falls off. Then you need to wash the heating element.

Faulty thermostat

The thermostat in Termex water heaters is located under the cover, next to one of the heating elements, and its sensor is located inside the tank.

Sometimes the thermostat fails. This element cannot be repaired; it must be replaced . To perform the replacement, you need to do all the preparatory steps, remove the cover, then remove the thermostat. But before dismantling, we recommend checking this part. To do this, use a lighter to heat the tip of the sensor (copper). If the thermostat is working properly, you will hear a characteristic click, which means that the protection mechanism has activated and the circuit has opened. Otherwise, you will have to replace the part.

Tank leak

No matter how trivial it may sound, but first you need to find where the water is coming from. A lot depends on this, since if the tank is rotten, you will have to buy a new water heater. So:

• if water oozes from the side seam, then the container is rusty and repairs will not be possible;
• If water comes out from under the lid at the bottom, then you need to disassemble the tank.

If traces of leakage are found in the places where the heating elements are attached, then your water heater is not hopeless and can be saved by replacing the gasket.

In the case of the second option, complete all preparatory steps, then remove the plastic cover. Next, take a close look at where the water is leaking. If it comes out near the flange, then the rubber gasket has deteriorated (less often this is a problem with the heating element). Otherwise, the tank is rusty and the boiler can be thrown away. To replace the gaskets, you need to remove the heating element. But it is necessary to carefully examine the heating element itself. If it is cracked, it is also better to replace it.

Other faults

If you have checked and replaced all the parts, but the boiler still does not work, then it is quite possible that the electronics have failed. The control board cannot be repaired, and it will be extremely difficult to find a similar one in a store. Therefore, in this case, we recommend contacting specialists.

Maintenance and operation instructions, tank capacity 15, 30, 50 and 80 liters

The device is controlled via the control panel, which is located on the front side. Such control can be either mechanical or touch, depending on the selected model.

In Termex models with a tank capacity of 15, 30, 50 and 80 liters and with mechanical control, control is carried out using buttons (1 or 2), which indicate the power of the water heater, where “1” means a power of 1.3 kW of energy, and the total power is 2 kW. The power level is selected based on the situation and need, as well as depending on the time of year.

A water heater with touch control and a digital screen is considered more functional and modern. Switching on and off the power of the device is carried out using the “ON/OFF” keys on the equipment screen. The screen also displays information about the current temperature level. The power can be adjusted using the button located in the middle - “Power selector”.

While using the Termex water heater, the temperature is adjusted:

In devices with a mechanical control system using a regulator on the front side of the device. In such a device, the temperature decreases by turning the knob from right to left, and accordingly, by turning the knob from left to right, the temperature increases, the maximum level of which can reach +75 degrees. You can turn off such an electric water heater by turning the regulator from right to left until it stops. It is worth noting that the Termex RZB10 water heater model does not provide for manual temperature control.

Devices with electronic (touch) control have an LCD display. Control is carried out using three touch buttons. You can also select the appropriate operating mode of the water heater on the screen. To set the required temperature, you need to press the “Temp” key a couple of times. Selector" on the front side of the device. In all Thermex electric water heaters, the default temperature value is set at 75 degrees from the factory, which is also restored in the event of an unexpected power outage.

If during operation of the water heater the automatic shutdown system operates, then after the time has elapsed, you must turn on the device using the corresponding key. If the device turns off again after turning it on, then you cannot do without involving a specialist in this matter. Under no circumstances try to open or repair the device yourself, as it can only be repaired with special tools and professional skills.

If during the cold season the water heater is not used for a long time, it is recommended to turn it off and drain the water from the internal tank of the device in order to avoid freezing and damage to the water heater.

Possible malfunctions and methods for their elimination of the Termex electric water heater

The above malfunctions are not defects of the EWH and are eliminated by the consumer independently or at his expense.

Maintenance

Maintenance involves the identification and subsequent removal of scale that forms on heating elements.
Also, sediment may form in the lower part of the internal tank of the device, which must also be removed. Descaling is carried out using special cleaning agents. The intensity of maintenance is determined by special workers after analyzing the accumulated scale. It is recommended to carry out the first maintenance of the device after a year of use. Failure to carry out cleaning work will lead to a decrease in operating efficiency and a decrease in the level of efficiency. In most cases, the cause of failure of water heaters is precisely the scale formed on the heating element. If the heating element or heating device fails and the cause is scale formation, then repairs are not covered under warranty. Periodic maintenance must be carried out by the user himself. To carry out proper maintenance of the device, you must: 1. Turn off the device 2. Wait until the hot water cools down, or drain it through the tap 3. Shut off the cold water supply 4. Unscrew the drain valve 5. You must put a regular hose on the valve and direct it to the sewer 6. It is also necessary to drain the hot water through the mixer 7. Now you can remove the device body, disconnect the wires, unscrew and remove the support flange 8 from the water heater. Check for scale on the heating element and at the bottom of the tank, if any, carry out appropriate cleaning. 9. Reassemble the device in reverse order.

This article discussed the technical characteristics and instructions for using a Termex electric water heater with a capacity of 30 liters. Note that the manufacturer has established a minimum service life of a Termex water heater of seven years. But this is only provided that the water in the system meets the necessary standards and does not contain a large amount of impurities and heavy elements, and that the installation, operation and timely maintenance rules are followed when using the device.

Recommendations for self-repair of Thermex water heaters

When hot water supply cannot be called stable, many people decide to get a household water heater, for example, a Thermex electric water heater. However, it can fail quite unexpectedly. This is especially true for inexpensive boiler models. Of course, you can immediately contact a specialist, or you can try to fix the breakdown yourself.

About company

The most popular model is the Termex storage boiler.
The Italian company Termex was founded in 1949. It specializes only in the production of water heating equipment, which is why it now occupies a leading position in the ranking of high-quality and reliable boilers.

Every year about two million units of heating products enter the market.

The concern includes its own research laboratory, design bureau, and workshop for the creation of instruments and spare parts for them.

Products are sold in more than 160 countries, including Russia. All devices come with a manufacturer's warranty, which averages 94 months. The Termex boiler comes with a 1-year warranty.

Error codes

Many Thermex water heaters are equipped with an electronic display that shows the main equipment error codes. Knowing how to read these emergency symbols can help you save big on professional repairs. The following errors occur most often.

• E1 or Vacuum - the storage tank cannot be completely filled with water when the heating element is turned on. Solution: turn off the heating element and wait until the container is full, and then turn on the heating element again.
• E2 or Sensor – the temperature sensor does not work. Solution: Disconnect the boiler from the power supply for 30 seconds and then restart the equipment.

E3 or Over Heat - the water heating temperature has risen to a critical level (95 degrees or more). Solution: Press the safety thermostat button.

Thus, if you notice problems in the operation of the Thermex water heater, this is not a reason to immediately contact the service center - armed with the above recommendations, a number of malfunctions can be eliminated yourself. But when starting repairs, remember that the main thing is to soberly assess the scale of the breakdown and not exaggerate your strength, so as not to provoke even bigger problems.

Internal tank

The design of the internal tank of the boiler must meet the criterion of increased corrosion resistance and at the same time withstand constant temperature changes, so manufacturers pay a lot of attention to this element, developing new coatings for the tank and applying methods to protect it.

Steel tanks coated with glass enamel or glass porcelain

This coating is obtained by spraying a protective layer followed by firing it at high temperatures (up to 850 o C). Glass enamel is not capable of oxidation, therefore it does not corrode at all. In addition, its smooth surface resists scale formation.

Photo of an internal enameled water heater tank

Paradoxically, the main disadvantage of such a coating stems from its advantage - the high hardness of the layer has little plasticity and over time, constant changes in water temperature lead to the formation of microcracks in its layer, which ultimately contribute to the destruction of the tank.

Manufacturers are constantly looking for new compositions for coatings of this type. For example, the addition of titanium powder equalized the temperature expansion coefficients of glass porcelain and steel, slightly improving the layer's resistance to cracking. You can slightly reduce the harmful effects of temperature exposure by setting the water temperature in the boiler to no higher than 70 o C, although you will still have to warm up the device at least once a month as much as possible to comply with sanitary rules. Another disadvantage of the glass-porcelain tank coating is the increased weight of the boiler. Companies that produce water heaters with tanks of this type provide a guarantee for their products for no more than 3 years.

Kinds

Thermex water heaters with a capacity of 50 liters are available in a wide range.

• Flow-through boilers are small-sized boilers that are installed in places where there is not enough space to install large water heaters. They have the undeniable advantage of quickly heating water. The disadvantage of instantaneous water heaters is that they cannot be used in rooms with several water intake points. They are used for small consumption of hot water, for example, for washing dishes.
• Storage heaters are protected from corrosion and scale, which increases the service life of the device. This is ensured by a special material - glass porcelain, from which the internal surfaces of water heating devices are made. To maintain the temperature of hot water, polyurethane foam is used, which prevents the water from cooling by more than two degrees per hour.

It is recommended to change storage heaters every 6 or 12 months. The main difference between storage equipment and flow-through equipment is that in the inner part of the tank there is a heating element, which is necessary to heat the incoming liquid to the required temperature. During the entire period of use, the water will be at the same temperature.

To select the optimal 50-liter boiler, you need to study the characteristics of the product lines.

Flat Plus has a flat white shape and is equipped with an ergonomic electronic unit, which includes a display with the heating temperature value.

It has the following characteristics:

• power – 2 kW;
• internal tank – stainless steel;
• body – plastic;
• automatic cleaning and draining of water;
• water heating time – 80 minutes.

The seams of the tanks are welded, which helps protect the tanks from depressurization. The electrical system is equipped with the ability to self-diagnosis, as well as adjust the liquid supply mode and heating level. If a fault occurs, all information about the fault is displayed on the screen.
• Praktik is small in size, which allows it to be installed in small apartments. It has a round shape made of stainless steel. By welding the seams, the seams are sealed and resistant to corrosion. The internal surfaces of the water heater are covered with a heat-insulating layer, due to which water heating and the efficiency of the equipment are stabilized. The power of the device is 2.5 kW.

The electrical circuit of the water heater is protected by a two-pole circuit breaker with a fuse. The delivery set of this equipment includes a technical description of the device and instructions for its operation. It also provides recommendations on how to connect the heater to the water supply system. Water heater instructions help with installation and provide information on proper use.

The Thermex Stream Manual flow heater is also very successful. The electrical diagram explains the operating principle of the equipment. It shows which parts provide the main workflow. In addition, the order in which each element is connected is indicated.

When purchasing a product, a sales consultant will explain how the electrical circuit works and tell you how to make the necessary connections. However, installation should still be carried out with the participation of a qualified specialist who will perform the work quickly and efficiently, observing all instructions related to the required electrical safety standards.

Advantages of Ariston water heaters – manufacturer’s version

The Ariston company reports the following advantages of its products:

• The breadth of the range covering all the needs of the household sector. And this is true - Ariston produces more than seven dozen models of storage water heaters, the capacity of which varies from 10 to 200 liters.
• High quality components. The manufacturer uses proprietary corrosion protection. Mounts magnesium anodes even in budget models. Supplies standard check and safety valves, as well as taps for draining water. Uses environmentally friendly polymer as insulation.
• Energy efficiency of devices. Models with a tank capacity of up to 0.1 m3 are equipped with a 1.0-1.5 kW heating element. Therefore, the operation of Ariston boilers does not overload the family or personal budget. After all, the lower the power of the heating element, the “easier” the payment for light.
• Ease of operation of the unit. Budget models are equipped with a mechanical regulator. Expensive boilers are equipped with digital control units. Moreover, any water heater has an internal temperature controller that optimizes heating in the selected operating mode.

Advantages of Ariston according to customers

Owners of Ariston boilers talk about the following advantages:

• Possibility of choosing a budget model - some 80-100 liter boilers cost no more than $90.
• Easy maintenance - the mounting hole of the heating element is equipped with a flanged pipe, which facilitates the process of assembling/disassembling the heating unit.
• Good heat resistance of the housing - a switched-off boiler cools down by 10-12 °C per day.
• Acceptable heating rate - relatively warm water can be obtained after 25-30 minutes from the moment the boiler is connected to the network.

Disadvantages of Ariston boilers

Ariston boiler owners include the following facts as obvious disadvantages of water heaters from this company:

Water heater Ariston AM 60SH2.0 Ei3 FE

• The location of the temperature regulator is inconvenient - on some models it is located at the bottom, under the lid.
• The absence of a standard reducer that reduces the pressure in the water supply to 6 atmospheres - the boiler can withstand only 7 bar, although the peak load is 16 bar.
• Problems with the check valve - some owners report cases of leaks.
• The mount is externally flimsy - there are complaints about the standard screws and the number of brackets - there are only two of them. Although no one talks about the facts of the water heater “falling off” from the wall.
• The lack of a standard power cable complicates the installation process, forcing the user to use an automatic fuse instead of a plug and socket.
• Manufacturing of the tank body from ferrous metal. As a result, the corrosion resistance of the boiler depends on the quality of the enamel or the Ariston AG+ proprietary coating. However, no one has any special complaints about the quality of corrosion protection.

After installing the water heater, proceed to its startup. To carry out this process correctly, it is recommended to follow the instructions for use of the heating apparatus. Proper start-up determines the lifespan of the boiler and the frequency of maintenance. Starting and setting boiler modes will differ depending on the type of water heater. However, in general, the order of inclusion is based on the same principles. It looks like this:

• Before turning on the device, it is necessary to close the shut-off valve for hot water supply from the common riser. This must be done even if there is a check valve;
• then they proceed to filling the reservoir with liquid and displacing the air;
• after which you should plug the plug into the socket and adjust the settings. You can start using the equipment in a few hours.

To check the functionality of the Thermex water heater, you need to perform the following steps:

• notice the power indicators turn on (they start to light);
• determine the temperature of the liquid leaving the mixer;
• After 20–25 minutes, you can see increased temperature readings on the touch panel.

In most cases, all consumers are satisfied with the Thermex 50-liter water heater. When choosing the optimal heating equipment option, reviews from real customers will help solve this problem and answer the most pressing questions. Many consumers unanimously concluded that a heater with a capacity of 50 liters is much more economical than larger units. The manufacturer offers a fairly wide selection of models - from the cheapest to designer boilers with electronics and a touch screen.
