Repair of TERMEX water heater. Part 2
Selecting a water heater
Specialized stores offer a wide selection of units that heat water.
The combination of high quality and affordable cost is contained in water heaters of the Thermex brand.
They are available in storage and flow types.
The storage units have a reliable design; they can be installed by a person who has no experience in such a matter.
Such a water heater can be installed anywhere in a house, apartment, or cottage. Through it, you can simultaneously supply heated water to the kitchen, bathroom, and shower faucets.

In case of any malfunction, the safety valve built into the system will operate.
Termex flow heaters are assembled from high-quality parts, so their service life is long and the quality of their work is high.
They, just like storage units, have a safety valve. With its help, the device is protected in case of damage.
Before giving preference to any type of boiler, it is worth analyzing the capacity of the tank, the conditions in which the equipment will be operated, and its appearance.
To connect the water heater, you can use the services of specialized companies.
Installation will not take much time, but will cost a lot of money. The cost usually depends on the type of water heater.
It is worth considering that the installation cost only includes basic installation activities. All additional procedures will have to be paid additionally.
There is another option - installing a boiler yourself. For installation to be successful, you must have experience working with plumbing.
By following the sequence of work, the water heater will be installed correctly.
At the same time, you can acquire the following benefits:
- money will be saved;
- you can acquire new knowledge and skills that will help solve problems in the event of a water heater failure;
- If the unit breaks down, you will not need to call a technician to dismantle the water heater.
To install a boiler with your own hands, you need to have the necessary tools and additional elements. To measure the distance between the holes you will need a tape measure.

The tank is installed using anchor bolts, which require holes in the wall. To make them, you will need a hammer drill with a drill of the required diameter.
In addition, you will need wrenches, pliers, screwdrivers, and wire cutters.
To seal joints, it is recommended to use tow, special paste or fum tape. Modern silicone sealants can be used.
You need to purchase shut-off valves in advance, and the corresponding number of tees for them.
Do not forget flexible connecting hoses and the required number of meters of plastic pipe if you need to change the water supply in the house.
To install new wiring, it is worth purchasing a three-core wire, the length of which should be no less than the distance between the boiler and the panel. In addition, you need an outlet and a circuit breaker for the panel.
Reasons why the heater does not work
The error code for a malfunction can be found in the instructions.
Installation is only permissible if the electrical network, sockets, circuit breakers are in good condition and cables of the required cross-section are available. If after connecting the boiler does not work, you need to check the electrical network:
- Using a tester, the functionality of the outlet is checked.
- Checking the correct connection of the terminals.
If power is supplied to the Thermex heater but the system displays an error, the user manual will be required. There you can find the fault code and how to resolve it.
If the user does not have basic skills in working with electrical appliances, it is prohibited to fix problems on their own. You need to contact a service center under warranty to replace a broken part or change a faulty device.
Carrying out preparatory work
Installing a water heater requires determining where it will hang or stand. For rooms with a small area, you can install a small boiler that will hold 50-80 liters of water.
Such tanks are most often hung on the wall. You can choose a water heater with any diameter and design.
If you need to install a container larger than 220 liters, then you cannot hang it on the wall. For such a tank you need to choose a place on the floor.

When mounting a water heating tank on a wall, it is worth choosing a load-bearing wall so that it can support the weight of the unit.
To secure the tank, you need to have anchor bolts available. In some models they come complete with the tank, sometimes you need to purchase fasteners separately.
For water heaters that are placed vertically and have a volume of 30-100 liters, you will need 2 anchor bolts.
If you need to install a horizontal unit with a volume of 50-100 liters, then you need to have 4 fastening elements.
The place where the boiler will be located must meet the following requirements:
- The water heater must be accessible throughout its entire service life;
- Installing the tank on the wall provides the ability to withstand a load equal to double the weight of the water heater;
- It is worth checking the wiring; it must withstand the operation of the water heater. If the wiring is old, it will need to be replaced;
- It is necessary to check the condition of the pipes in the room, connections must be created to connect the water heater.
Water heater installation
Due to their size, Termex instantaneous water heaters can be installed above the sink, which will significantly save space in the room. Water is heated in a metal flask.
Due to the use of powerful heaters, it is worth making a separate machine for a flow-through boiler.
Thus, the general wiring in the house or apartment will always be in good order and will not depend on the unit being turned on.
The water heater installation scheme can be temporary or permanent. In the first case, a cold water supply is connected to a tee, and then combined with a water heater.
The stationary installation scheme involves the creation of a parallel system for water intake and liquid supply.
Tees must be installed separately for cold and hot water. Shut-off valves are installed behind the tees.
The inlet pipe of the instantaneous boiler must be connected to a water pipe with cold water.
The outlet pipe is connected to a tap through which already heated water is supplied.
The tightness of the system must be checked during a temporary, permanent connection.
To do this, you need to turn on the hot water tap in the shower, bathroom, and kitchen at the same time. If there are no leaks, then you can turn on the electricity.
Termex storage water heaters do not have the same wiring requirements as instantaneous ones.
Installation and connection requires the use of a circuit in which water can be supplied simultaneously to the tap and shower.
Installing this type of boiler yourself is not difficult if you have the necessary tools. Markings are applied to the wall where the water heater will be located.
Fastening elements are installed at the marked locations.
After mounting the tank on the wall, you will need to connect the water and install a safety valve.
When connecting the water supply, make sure that the valve is closed. After the entire system is installed, the operation of the Termex water heater is checked.
When checking, all connections of the pipeline parts must be sealed, and heated water must come out of the tap.
To see clearly what the installation diagram for a Termex water heater is with your own hands, you can watch the video in our article.
Examples of Termex boilers
All supplied devices are designed for a mains voltage of 220 V, the excess pressure in the main water pipeline is more than 0.5 Ati. Let's look at the most popular broiler models used in everyday life.
Thermex water heater with a volume of 80 liters
For a family of three or more people, the best water heater would be a Thermex device with an internal tank volume of 80 liters. The volumetric tank maintains temperature for 9 hours. The models have different shapes and locations, are compact and fit comfortably into the allocated space. It is recommended to choose a device with a water heating element in the form of a heating element; the spiral will fail faster. Before installing the Thermex 80 liter water heater, read the instructions for using the device and safe operating conditions.
Paragraph 3 lists the equipment delivery package, including connection elements. It is necessary to check the completeness in accordance with the specifications before purchasing.
The buyer needs to know that the warranty period for electronic and electrical parts on all Termex products is 1 year. But the mechanics are designed for many months of trouble-free operation. The price of an 80 liter water heater depends on the materials used and equipment. The use of electronic control with multi-level process regulation will make the model noticeably more expensive. The more complex the shape of the model, the higher the device is rated. The product becomes significantly more expensive if, instead of enameling the inner surface, a tank made of special austenitic steel is used.
The device is based on a physical process associated with the occurrence of stray currents, electrochemical corrosion, possible water hammer, and wear of gaskets. Do-it-yourself repair of a Termex 80 water heater is allowed only by cleaning and replacing the heaters. A professional can set up the automation and electronics correctly.
Selecting a 50 liter water heater
A small container can be installed even in cramped spaces.
liters of water are enough for 1-2 consumers. You should pay attention to the Thermex ER 50 V water heater. These models are leaders in demand. A heater power of 1.5 kW will not create a high network load. Heating water within 1 hour 45 minutes. The steel tank is coated with bioglass porcelain enamel and maintains the quality of water as in a ceramic vessel. The tank is guaranteed for 7 years. Retail price 6757 rubles.
The Thermex IF 50 V water heater is more complex. It has a metal tank made of stainless austenitic steel and two heating elements. In total, they provide a power of 2 kW, but the electronic control system allows you to connect one element at a time, depending on the task on the display. The price of a Termex 50 liter water heater of this design is 11,259 rubles.
30 l model
The miniature water heater Termex 30 is presented by the company in various designs. There are models with an enamel tank and an eternal vessel made of Japanese stainless steel. The outer casing can be plastic or metal, coated with durable paint. Devices with heating elements of 0.7, 1.3, 2.0 kW are installed on different models. It is easy to select a device that creates a low load on old networks. There is enough water for one person; a new portion is heated within an hour. The service life of the installations is at least 10 years, with timely cleaning and replacement of electrodes.
Even a small boiler is more economical than a instantaneous water heater, which requires separate wiring. With the installation of a boiler, the quality of life in a rural or country house will improve. When choosing a device, it is necessary to take into account the state of the electrical network and the number of users. The more powerful the device, the faster the water will heat up, but the same amount of energy will be consumed.
How to properly connect a water heater to the water supply system
In order for the connection of a flow-through storage tank to be correct, a certain sequence must be followed.
Most often, each kit contains a diagram that describes the installation of the boiler.

Information for each model:
- the number of holes that will need to be made in the wall;
- types and quantity of fasteners;
- detailed description of pipe connections;
- what units and equipment will be useful for the installation of the tank to proceed correctly.
To connect a Termex boiler with your own hands, you need to perform the following sequence of actions.
It is worth inspecting the water pipes. If they are worn out, it is recommended to replace them with new ones.
It is allowed to install pipes from any material: metal-plastic, plastic, steel, copper.
It is imperative to install a safety valve on the boiler. Its role is to protect equipment from excess pressure.
Installation must be carried out on the pipe where cold water is supplied. Be sure to use fum tape or sealant to ensure a tight seal.
Ball valves are installed on the pipes that are connected to the water heater. Thanks to them, you can regulate the flow of water into the container.

It is recommended to install a pressure reducer on the cold water pipe. It will regulate the inlet pressure.
At the outlet, water will be supplied at constant pressure. This device is important when installing a boiler in multi-story buildings, where the pressure in the water supply system fluctuates.
After the installation of the water supply is completed, you need to open the tap to supply water to the tank. After it is filled, well-heated water should come out of the tap.
At this stage, the tightness of all connections is checked.
