How to properly disassemble the Termex water heater with your own hands

Very often, during a move or when a malfunction occurs, people face a difficult task, because they need to disassemble a water heater. Do not forget that any boiler needs frequent regular cleaning and replacement of protection. In most cases, people do not want to overpay money or wait for a master, so they try to solve the problem on their own. Initially, it may seem that disassembling the boiler is quite a difficult task, but this is a misjudgment.

Analysis of water heaters of various brands

You can disassemble the device carefully, knowing the manufacturer and following clear step-by-step instructions.

Water heater Termeks

Since all water heaters have almost the same system, you might think that they need to be disassembled according to the same scheme. But manufacturers add some of their own details and functions, so each company has its own algorithm:

Shut off the water supply. In most cases, there is a tap or valve under the boiler that must be closed.
De-energize the boiler, after which it must be disconnected from the electricity.
Use a flat-blade screwdriver to remove the protective cover. In some cases and on some models, it sits tightly, so you need to perform the movements that are made when opening the canned food.
Use an indicator screwdriver to check if there is an electric current in the boiler. If everything is done correctly, the light in the screwdriver will not light up.
Drain the water from the water heater, for this there is a step-by-step algorithm, which you can learn about by watching the video on various resources.
You should take a snapshot of the connection diagram so that you do not confuse the wires later. After the shot, you can start disconnecting the wires.
The nuts that secure the heating element and the thermostat should be unscrewed one at a time. This is necessary so that the water that has stagnated in the tank will gradually drain.
Wipe the heating element and thermostat with a dry cloth.

The analysis is over.

Water heater Ariston

Procedure:

De-energize the device by disconnecting it from the power supply.
Remove the protective cover, which is secured with nuts.
Next, you should disconnect three cables: 1 - phase, 2 - zero, 3 - ground. This is done using an indicator screwdriver. The first two wires free the thermostat, so you can easily pull it out of the tube.

Further, the algorithm for parsing the Ariston boiler is similar to the previously presented manufacturer.

Protective cover

Water heater Polaris

In most cases, people tend to prefer Polaris boilers. The parsing order is as follows:

Disconnect the boiler from the power supply.
Drain the boiler. You need to get access to a tap that removes hot water from the reservoir.
Next, you should disconnect the thermostat, in this case it is not fixed, but simply installed on the terminal block.
The next step is to drain the remaining water from the tank.
Unscrew the retaining bracket and remove the heating element from the storage tank at the correct angle.

Water heater Electrolux

Procedure:

If the previous water heaters could not have been removed from the wall, then in this case you cannot do without it. Therefore, the first point of the algorithm is to remove the boiler from the wall. Before that, it is imperative to drain all the water from it.
The removed boiler should be turned upside down with the fittings and the protective cover removed from it.
Then, one by one, you need to start removing the thermostats, the thermometer's power supply, the thermometer itself, unscrew all the nuts to one, and eventually remove the heating element mounting flange.
Then take out the heating element.Further actions depend on the reason for disassembling the boiler. If the device was disassembled due to a breakdown, then the heating element should be replaced, if the boiler just needed to be cleaned, then all parts should be wiped with a dry cloth and various contaminants, such as plaque and rust, should be removed.

Water heater Garanterm

Algorithm of actions:

The first point of the algorithm for parsing the Garanterm water heater, as in most cases, is a power outage.
Next, drain the water from the boiler. In order for the water to flow from the two taps and drain as much as possible, the common apartment tap should be turned off so that the water can flow out without problems.
The next point is to work with different wires. We dismantle the terminals from the contacts of the heating element.
We unscrew the screw with the grounding wire, then the screw for the power cord retainer, as well as the screw for the protective block.
Remove all protection sensors and thermostat from the slot.
Next, you need to unscrew the last five bolts, and start disassembling the insides and, for example, cleaning.

Water heater AQUAVERSO

The algorithm for parsing this water heater is very similar to the algorithm for parsing the Termex boiler, which can be found at the beginning of the article. Only in this case, the water from the boiler must be drained immediately after the power is cut off.

Boiler Aquaverso

Water heater Atmor

This type of water heater is not recommended to be repaired on your own, since the manufacturers have set it up so subtly that independent intervention can lead to severe damage and you will have to pay many times more money for repairs than for cleaning and disassembling.

There were cases when independent penetration into Atmor boilers led to a short circuit in the wiring, to fires, electric shock, or a complete breakdown of the water heater.

Superlux water heater

The SuperLuxe boiler can be disassembled using the Electrolux boiler disassembly diagram. These types are completely identical, therefore, parsing, installation and everything else are the same for them.

Water heater Goranje

Procedure:

Disconnect the device from the mains.
Drain the water heater.
The first step is to remove the cover. In most cases, people cannot remove it and even break it, since it is plastic. It is very easy to remove it, pry it with a screwdriver from below and push the front panel towards you.
Next, pull the handle that regulates the temperature. Since the handle is not secured by anything, it will be quite simple to do this. Unscrew the two screws and the cover can be removed.
The next step is to disconnect all the wires, it will be very difficult to get tangled in them, since they are all of different lengths and when assembled, each fits perfectly into its place.
Next, you need to unscrew the flange, which is held by six nuts, and start cleaning the inside of the boiler.

Important! When cleaning the boiler and its components, in no case should you use sandpaper, brushes and much more, which can damage the surface. It is not necessary to rub every detail to a shine, and especially the inside of the boiler itself, scale on the walls of the water heater protects it from corrosion, so it is undesirable to get rid of it. Use a regular microfiber cloth to clean the parts.

Epico water heater

Algorithm of actions:

First you need to disconnect the boiler from the network. Drain the water and remove the non-return valve.
Remove the cover, which is secured with two bolts next to the pipes.
Pull out the thermostat, it is very easy to do, you just need to slide it down. If the wires interfere, then they must be removed from the terminals.
Next, you should drain the remaining water and scale into the container and you can get all the remaining parts.

Haier Water Heater

In this case, it is better to turn to professionals, since it is very problematic, and it will be difficult for an ordinary person to understand it.

Cleaning the water heater

There are also a large number of other models of water heaters, for example, Timberk, Stiebel Eltron, AEG and many others. All of them differ from each other in something, size, color, complexity of the scheme.

The main elements and the principle of operation of the TERMEX models

In order for the principle of operation of the water heater to be understood, it is necessary to have an idea of the key design details and the main indicators of the device.

The main components of the water heater:

Hot water outlet pipe - made of special stainless steel, corrosion-resistant, wear-resistant.
Inner tank - steel container, alloyed with special impurities. They provide high corrosion resistance and excellent mechanical strength.
Large magnesium anode - an important part of the boiler that affects the service life. It is a metal rod coated with magnesium alloy. The main purpose is to take over all the corrosiveness of the water and to protect the tank.
Steel flange - platform on which are mounted: heating element (heating element), thermostat, magnesium anode. Attached with 5 or 6 (depending on model) nuts to the body for quick removal and installation.
Outer shell of the water heater - made of enamelled steel sheet. It is applied by powder coating, which gives high protective and decorative properties.
Internal tank lining - a unique special coating developed and patented by TERMEX.
Cold water inlet pipe- made of special stainless steel, corrosion-resistant, wear-resistant.
Thermostat- device for automatic regulation of water temperature. TERMEX uses thermostats with a double degree of protection.
Heating element - tubular electric heater - the "heart" of the boiler.

The need and undoubted benefit when using water heaters from Termeks is shown in this video!

This coating is glass porcelain with special properties:

Antibacterial properties - the water in the tank is always clean and fresh.
Chemical neutrality - Harsh chemicals dissolved in water will not react with the coating.
Strength and elasticity - protects against thermal shock and pressure surges.
High adhesion - detachment of the paint during operation is practically impossible.
The coefficient of linear expansion of glass porcelain is equal to the coefficient of linear expansion of steel. This factor helps to protect the structure from cracking.
Thermal insulation- a layer of environmentally friendly polyurethane foam. The high density of the material is effective in conserving heat, which reduces the use of electricity.

Principle of operation

The principle of operation of a water heating tank is quite simple. We open the hot water tap. Cold water entering the tank from below is heated by a heating element installed on the flange. Heating occurs up to a certain temperature.

The water is distributed evenly throughout the volume thanks to the divider. The thermostat located at the bottom regulates the set temperature - turns on the heating element when the water cools down or leaves, and turns it off when the set temperature is reached.

The heated water rises by convection up the tank, where the hot water intake tube protrudes. The liquid inside does not mix, therefore we have a gradual increase in temperature along the height of the container.

When the tap is closed, the water flow stops and heating continues to the desired temperature. The speed of heating is due to the power of the heating element and the volume of the tank.

Tools for disassembling and collecting water heaters

To disassemble the device, a small number of tools are required, in most cases every person has them at home, so no additional costs will be required.

Before you start disassembling the water heater, you need to prepare all the tools in advance and lay them out in front of you, so that if something happens you will not be distracted by looking for this or that screwdriver.

List of required tools:

Indicator screwdriver.
Phillips and flat head screwdrivers (depends on the screws that screw the parts in).
Adjustable wrench.
A set of spanners.
Knife and scissors.
Tow.
Microfiber cloth to wipe down the insides and parts.

Is it possible to repair Termex water heaters with your own hands?

The world famous manufacturer of water heating equipment Termeks has launched production in Russia. The devices are simple, and a person with minimal locksmith skills can independently repair the Termeks water heaters. This is relevant, since service centers can not be found everywhere in the domestic open spaces. Having carefully studied the technical instructions, you can diagnose malfunctions.

Disassembly of the safety valve

The safety valve is an important thing in the operation of the water heater. This valve helps the water heater not to explode. It regulates the pressure inside, so you need to install it correctly so that when you turn on the boiler does not explode and starts working correctly, that is, to heat the water, and not just drive it through yourself.

Each boiler has its own individual valve, so a specialist should choose it.

The safety valve is like a simple piece of pipe with a small handle, with which the pressure inside the boiler will be regulated. The valve can be easily removed and installed back, but this must be done correctly in order to avoid breakage and other unpleasant situations.

Safety valve

Typical malfunctions and their cause

Since the boiler systems have a relatively simple design, their malfunctions do not differ in variety. They all boil down to the following manifestations:

The appearance of extraneous potential on the case (they say that the equipment "shocks").
The liquid in the boiler heats up too slowly (and sometimes it does not heat the water at all).
The heated water cools down too quickly.
Leaks are detected.

When a water heater "shocks", then the cause of the breakdown is most likely in its electric heating device (TEN) or wires suitable to it.

If a foreign potential appears on the case of the device, turn it off immediately to avoid possible electric shock. If a lack of water heating is detected, the causes of the problem must be looked for either in the thermostat or in the heating element, the failure of which usually manifests itself in this way. It is extremely rare that this happens due to a breakdown of the control board.

If a slow heating of the coolant is detected, this can also happen "through the fault" of the heating element, on which a thick layer of scale accumulates during operation. The penultimate of the named cases (rapid cooling of water) is the most unpleasant, since this means that the tank has lost its thermal insulation properties and the need to replace it. Usually the same decision is made when leaks are detected in the tank.

From the analysis of possible reasons, it can be seen that in order to repair the boiler, one way or another, the tank will have to be removed from it, which is impossible without a special tool. Therefore, before starting the repair, you will have to worry about purchasing a set of adjustable wrenches, screwdrivers and pliers.

And to repair the electrical part of the water heater, you need to stock up on a special device - a multimeter that allows you to measure voltages, as well as check the health of wires and circuits.

Disconnection from the mains

An important and main element of disassembling a water heater is to disconnect it from the electrical network.It is simply necessary to do this, since the safety of not only the one who disassembles the boiler depends on it, but also of all those nearby, because if the boiler explodes, then the losses will be significant.

Even when the device is disconnected from the power supply, it is necessary to check the presence of current in the wires using an indicator screwdriver, since when the water is drained, the wires may short-circuit and a fire will start.

Dismantling the water heater, cleaning it inside or repairing it will not be difficult if you follow the clear instructions that are attached in a special book. If the documents for the boiler are lost, then the parsing algorithm can be found on the Internet in various forms: in written, exemplary, etc. But do not forget that there are such models of boilers, penetration into which is possible only by a specialist, since the developers have made the internal system difficult for ordinary people to understand.

When a water heater needs repair

The first sign of a malfunction will be the absence or weak heating of water in the drive or flow system. Possible malfunctions are analyzed. Repair of the water heater is required if:

there is no signal about the power supply, there is no current in the electrical circuit;
there is power, the indicator is on, and the water does not heat up - the heating element is out of order;
the thermostat has failed;
there are leaks or fistulas;
anode replacement is required.

Gas instantaneous water heaters

The devices require regular maintenance: lubrication of the internal valves to prevent gas and water leaks. Moving rods are periodically lubricated, rubber or silicone gaskets are replaced.

When carrying out work, the valves are closed. After processing, the nodes are washed to ensure the tightness of the joints.

When converting a water heater to a new type of gas, a trivial pressure adjustment does not give the desired result. We have to buy new components, for example, the pilot burner nozzle. Without additional adjustment, the water valve does not work correctly: a strong gas flow can depress the spring, and if there is no water supply, gas will continue to flow to the main burner.
