How to use a Thermex boiler correctly - operating instructions for Thermex water heaters. Water heater "Termex" (80 liters): instructions for use. Scheme

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.

Instructions for installing and connecting the water heater

Boiler installation consists of 3 main stages:

Installing the unit on the wall.
Connecting the device to the water supply system.
Wiring assemblies and connections of the water heater to the network.

The installation of the boiler must be carried out by qualified personnel with appropriate skills. Improper installation of the device can lead not only to improper operation of the unit, but also to damage to property or human health. You can buy a Thermex water heater and order an installation service in Tyumen.

Placement and installation of the device

The installation location of the water heater must comply with safety standards. You need access to sewerage, distance from electrical appliances (and other equipment for which contact with water is undesirable), the possibility of emergency drainage and autonomous connection to the switchboard. The installation process takes place in several stages:

Taking measurements, marking anchor attachment points.
Drilling holes, screwing in anchors.
Mounting the boiler to the wall.
Connecting taps to water supply circuits.
Installation of filters and pressure reducer on the cold circuit.
Installation of a safety valve, tee, drain hose and other auxiliary and protective elements.

To seal the seams between elements when installing a water heater, flax is used. It protects against the effects of hot water.

Electrical connection

The last stage of installing the boiler is connecting it to the electrical network. The procedure consists of the following steps:

Laying wires in grooves or in an overhead box.
Connecting the RCD to the panel board.
Route the cable from the electrical panel to the fuse.
Connecting the boiler to the machine with a separate cable.
Connecting the “phase”, “zero” and “ground” wires to the bottom of the water heater.

The wiring connection to the boiler is carried out exclusively by professionals.

The devices are not equipped with cords and a standard plug-socket system. Instead, they are connected to the network using a 3-core cable d 2.5-3 mm with the mandatory installation of a 16-amp fuse.

Trial run

Boiler installations are often carried out by professionals. They are the ones who should carry out a test run immediately after installation. But if you installed everything yourself, then be sure to do the following.

Make sure that the water heater is installed efficiently, according to its instructions.
Inspect it for leaks. Fill with water after disconnecting from the power supply.
To see when the tank is full, open the hot water valve. If water flows, the tank is already full.
Close the valve and examine the outside of the device.

Only after this can you safely connect the boiler to the power supply and set it to the desired temperature.

Advantages and disadvantages

Having decided on the brand and model of the water heater, you should study in detail all the advantages and disadvantages of the product, and only then purchase it.

Thermex electric boilers are produced using the latest technologies and developments, so they are endowed with many advantages.

Economical energy consumption. Regardless of the volume, the device consumes 1.5-2 kW. Thanks to additional thermal insulation, the desired water temperature is maintained for up to nine hours.
The ability to properly distribute energy. Regardless of how far the boiler is from the point of water consumption, the temperature remains unchanged; both pipes and walls do not heat up.
Availability of an automatic shutdown system in emergency situations.
High degree of strength and reliability of structures. It is due to the use of high-quality materials in production - plastic and stainless steel.
Easy to install and connect to the electrical network. To connect the device, a three-phase power supply is not required.
Environmental friendliness. Each device has an antibacterial system that prevents the development of microbes.
A variety of shapes (flat, cylindrical) and sizes, thanks to which the model can be installed in a small room or in a closet.

Long operational period. Reviews from boiler owners indicate that the devices can operate without breakdowns or failures for 7-8 years.
High performance: 80 liters of water can be heated in 1.5-3 hours.
Water supply to several points.
High safety indicators.
Some models have a silver heating element.
Resistance to corrosion processes and deformation.
High class of housing protection against moisture.
Most models have a self-diagnosis system.

Despite the huge number of advantages, Thermex water heaters have disadvantages:

high price segment;
the need for an additional filtration system that protects against water with increased hardness.

In addition, boilers from this manufacturer require special maintenance: regular cleaning of the tank, heating element and replacement of the magnesium anode.

Features of gas connections

When connecting gas stoves, water heaters and other types of equipment, flexible hoses are also used. Unlike water models, they are yellow and are not tested for environmental safety. For fixation, end steel or aluminum reinforcement is used. There are the following types of devices for connecting gas appliances:

PVC hoses reinforced with polyester thread;
made of synthetic rubber with stainless steel braid;
bellows, made in the form of a corrugated stainless steel tube.

The Santekhkomplekt holding offers engineering equipment, fittings, plumbing fixtures and devices for connecting them to communications. The assortment is represented by products and materials from well-known foreign and domestic manufacturers. Discounts apply for bulk purchases, and product quality is confirmed by standard certificates. For information support and assistance, each client is assigned a personal manager. The ability to arrange delivery within Moscow and to other regions of the Russian Federation allows you to quickly receive the purchased goods without unnecessary hassle.

How to choose?

Any electrical appliance is selected according to certain criteria, and the boiler is no exception in this matter.

When choosing a water heater from the well-known manufacturer Thermex, you should pay attention to some factors.

A heating element. It is preferable to choose models with built-in heating elements rather than coils, since the latter quickly burn out.
The material used to make the tank and body, since the service life of the device depends on this. It is also desirable to have an antibacterial coating and protection against corrosion and mechanical stress.
The presence of a safety valve, which is necessary to drain water in the event of a long break in the operation of the device.
Anti-corrosion anode that performs a cleaning and protective function.
Protection class. The high quality of the device is ensured by protection levels IP 24 and IP 25.
The power of the water heating device and the presence of different modes, with the help of which you can significantly save electricity, and therefore money.
Installation method: vertical or horizontal. When the device is positioned horizontally, water of the same temperature is evenly distributed.
Type of device - storage, instantaneous or combined boiler.

After purchasing a water heating device, you must carefully study the instructions for use and only then use it.

Instructions for use contain the following information:

purpose of the device;
main technical characteristics;
equipment;
detailed description and principle of operation of the water heater.

The last point is a paragraph that includes precautionary measures, which spells out everything that should not be done:

turn on the boiler when there is no water in the tank;
remove the cover while the device is operating;
use a boiler without a filter, etc.

Situations that require draining water

Long-term and trouble-free operation of the device greatly depends on its correct operation. Note that the boiler must be filled with water at any time, since the material from which the tank is made is metal. It rusts when exposed to air. Water interferes with this process. But there are situations when you simply need to drain the water. In accordance with the instructions for use, in order to operate the device, it is necessary to periodically perform a medical examination and clean it from accumulated dirt. Water heaters are often installed at the dacha or in other rooms that can freeze. In these circumstances, the owner has to drain the water from the device. Due to savings, more and more people prefer to perform this procedure themselves.

Operating principle of an electric heating tank

The operation of the water heating tank is based on the principle of convection:

Cold water always enters the storage water heater from below, and when heated, it rises upward, where the hot water intake tube is located.

cold water enters the tank through the inlet tube;
the heating element turns on and heats the water to the set temperature (there is a regulator on the dashboard with which the temperature is set);
thanks to convection, hot water rises independently to the top of the tank;
the hot water outlet tube is located at the top of the device, through which the heated liquid enters the pipeline;
when the water temperature in the tank drops, the thermostat turns on the heating element, and when it reaches the maximum, it turns off.

it-yourself repairs are carried out in the same way for both the 80-liter Thermex water heater and the 50-liter Thermex water heater . Their design is identical, only the tank volumes differ.

Inclusion

The sequence of actions to turn on the Thermex boiler:

It is necessary to shut off the hot water supply to the riser. This is one of the essential rules on how to properly use a heating device. If you have a check valve, you still need to shut it off, since its breakdown, which you may not immediately find out about, will result in you providing hot liquid to all neighbors in the riser.
Fill the tank with water; to do this, open all the valves on the boiler (cold inlet and hot outlet at the boiler). Open any faucet in the apartment so that the air comes out of the tank; this moment will come when liquid flows from the tap.
Then connect to the mains. After 15-20 minutes, check if the liquid is heating up.
When you turn it on for the first time, you must set the water heating temperature in the range of 70-75 degrees.

Brand Description

Thermex is an international corporation that has been on the market for 70 years. She represents a group of companies. This is a large manufacturer of heating equipment. Its peculiarity is the introduction of independently developed technologies. The manufacturer does not use other people's ready-made solutions.

The company was founded in 1949. In those years, production was located only in Italy. The company now offers services in 60 countries. Termex products have become widespread due to their quality, reliability, and long-term operation. The company entered the European market in 2007. More than 100 branches have already been opened.

Equipment of this brand can be used in difficult conditions. It is developed taking into account the influence of negative external factors: high and low temperatures, changes in coolant parameters in heat supply systems (within +5...+20 °C), differences in liquid compositions. In this case, the characteristics of highways and water supply sources are taken into account. The company focuses on the individual characteristics of different markets.

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.

The boiler does not heat the water well. Causes and methods of eliminating them.

Have you started to notice that you are getting less hot water? Do you feel like your boiler is not heating the water well? Let's figure out what could be the matter:

1 The valve on the common riser is not completely closed.

The valve is either not closed or is not in working condition, thereby hot water goes to the neighbors below, and you get noticeably less water from the water heater. To reliably determine whether hot water is flowing to your neighbors, you need to check that the pipe below the valve is hot/warm. If the pipe is warm, then it is necessary to replace/close the valve.

2 The temperature setting on the thermostat was changed.

It often happens that children/wife/mother-in-law changed the temperature setting of the boiler without your consent. Thus, you begin to receive significantly less hot water. Check whether the temperature has remained at the same level or has changed downward?

3 The first heating element is switched off.

In boilers where two heating elements are installed, someone may have turned off one heating element without your consent. Check this, because one heating element heats the water twice as slowly.

Frequent errors and malfunctions

When you turn on the water heater, various problems and malfunctions periodically occur. List of common problems and their solutions:

Problems with the electrical network. The broiler has a lot of power, so due to its operation, the socket often burns out or the wiring becomes unusable. To correct the situation, it is worth ringing the electrical network with a special tester, and if faults are detected, replace damaged elements.
Burnt out or broken heating element coil. With this breakdown, the device not only does not work, but also produces an electric shock when you touch the body. The problem is solved by replacing the faulty part.
Overheating protection triggered. This happens when the temperature inside the device exceeds the maximum allowable value. The reason for this may be the accumulation of scale on the heating element - then it needs to be cleaned. In addition, such a malfunction occurs due to a broken thermostat - it will have to be replaced with a new one.
Incomplete water tank. The problem is solved by pumping out and refilling the tank with liquid, as well as removing excess air to the outside.

Water heaters with touch control display an error code on the display. A complete list of them with a description of common breakdowns is contained in the operating instructions that come with the device.

Varieties of Thermex water heaters 50 liters

There are a large number of units in this group. They differ in several parameters, including: dimensions, weight, installation method (installation, connection), electrical characteristics, functionality, degree of protection against scale. Review of Termex 50 l boiler models:

Thermex ERS 50 V Silverheat. The tank is cylindrical in shape. It is made of metal, the walls are protected from the inside by enamel, thereby reducing the risk of damage to the boiler due to rust. Communications are connected from below, the installation method of such a unit is vertical. A mechanical method is used for control. Withstand pressure - 6 bar. The device heats the liquid to a temperature of +75°C in 105 minutes. Power is 1.5 kW. The kit includes an RCD.
Thermex Fusion 50 V. In terms of the main parameters, this model differs little from the previous one: the type of control is mechanical, the mounting on the wall is carried out vertically, the method of connecting communications is bottom. However, it looks different - in the form of an oblong cylindrical device of small diameter, but of significant length. Withstand pressure - 7 bar. The unit has a higher power - 2 kW. This affects the heating rate. So, the boiler will bring the liquid to the required level of +75°C in 65 minutes.
Thermex GIRO 50. The device is made of stainless steel, the inside of the tank is covered with enamel. The installation type is universal, which means that the unit can be fixed to the wall vertically or horizontally. This is due to the location of the hooks on the boiler. The pressure inside the tank is no more than 7 bar. The heating element is wet, tubular type. The power of the unit is 1.5 kW, largely because of this, the heating rate of the liquid increases: it is brought to +75°C in 105 minutes. There are no auxiliary functions other than display.
Thermo 50 V Slim. The internal walls of the device are covered with bioglass porcelain. The tank is characterized by a cylindrical shape. Like the previously discussed analogues, this model is installed vertically on the wall. You can connect to the boiler from below. Control type: mechanical. It is important to use such a unit in accordance with the pressure of the water supply line. For this model, the withstand rate is 6 bar. The power of the water heater is higher—2.5 kW—than that of its analogues. Thanks to this, the liquid temperature of +75°C is achieved in just 1 hour.
Thermex Nova 50 V Slim. This is an enameled cylindrical boiler. It is designed to be installed on a wall in a vertical position. The pipes are connected from the bottom. Such a boiler is controlled mechanically. The maximum temperature is +75°C. The water is heated to the specified value in 80 minutes. This is due to the high power - 2 kW. The advantage of this model is the presence of a dry heating element. However, there is no display, which makes it difficult to control when changing the values of technical parameters.
Thermex MK 50V. This is a flat water heater, it is manually controlled mechanically. The upper limit of withstand pressure is 7 bar. According to the main parameters, this model does not differ from the previously discussed one: power - 2 kW, maximum temperature is +75°C, heating duration - 80 minutes. It is equipped with a wet-type heating element; there is no display. The boiler is equipped with an RCD device. There are no auxiliary functions other than indication and overheating protection.
Thermex Optima 50. This is another flattened model. Characterized by a rectangular shape. This is an enameled boiler, protected from rust thanks to the coating on the inner walls of the tank. The unit is controlled using an electronic system. The pipes are connected from below. The device is equipped with a temperature indicator and can withstand pressure of 7 bar. The maximum water temperature in the tank is +75°C. Heating element of wet type, tubular. There is no display, and auxiliary functions are also not provided.

Device contents

You can purchase a water heater together with various elements (parts, devices). The contents depend on the model, but most often the boiler package contains: a user manual for the device, an RCD, a bag with fasteners, a check valve, and a magnesium anode. The latter is installed inside the tank before installation begins.

The set of models of this group (liquid volume 50 l) includes all the listed elements, which is an advantage, since you do not have to purchase parts and the device separately.

Instructions and operating features

The activation method depends on the model. Some boilers have a button for this. In order to monitor the condition of equipment, a display is often installed. It is not available in all models of 50 liter Thermex water heaters. If possible, use the regulator to set the required power value. For many devices in this group, this parameter does not change. In addition, you need to set the temperature value.

During operation of the boiler, you can change the temperature values at your discretion. When the network parameters change or the operation of the unit is disrupted, the RCD is triggered. To turn it on, you need to press the button located on this device. You can begin operating the equipment after installation by opening the mixer taps, which will allow air to escape from the tank.

The frequency of device maintenance depends on the composition of the water supplied to the boiler. For this reason, maintenance can be performed every 6-12 months, and sometimes once every 2 years. To do this, the unit is disconnected from the network, the water is drained from the tank, it is dismantled and washed from the inside. Additionally, a new magnesium anode is installed, since the old one quickly deteriorates - within a few months. In addition, it is necessary to clean the heating element from scale. Then it is installed in place and the device is reassembled.
