Atmor storage water heater DIY repair

In detail: atmor storage water heater DIY repair from a real master for the site my.housecope.com.

Today, various water heating devices have become a completely natural phenomenon in our homes and apartments. Manufacturers in many countries produce a huge number of all kinds of models of this equipment that satisfy any consumer demand. But when purchasing a water heater or boiler, few think about meeting the requirements for the installation and operation of the device. As a result, this creates serious inconveniences and leads to significant costs in the repair process.

A significant number of manufacturers supply low-cost, low-quality products to the markets. Ambulance water heater breakdown This group does not come as a surprise, since even the minimum warranty obligations for the products are given. However, good-quality products, distinguished by their quality and reliability, may be repaired soon after purchase due to a number of factors that are not at all difficult to avoid.

The main causes of malfunction of the water heater hiding in our everyday life. Hard water and unstable power supplies have a detrimental effect on technology. Various salts are present in large quantities in our water. They are the ones that lead to the formation of scale inside the devices and working circuits. The installation of flow filters at the heater inlet will help to significantly reduce the salt content. In the supply networks of most regions, the voltage and frequency can change significantly in a short period of time. Connection of surge protectors or uninterruptible power supplies will solve the problem.

It is important to install and connect the device correctly. Many breakdowns occur precisely due to mistakes at this stage. Even ignoring the usual grounding can not only lead to electric shock, but will also contribute to the accelerated destruction of the magnesium anode and severe corrosion of all elements inside the tank. The optimum heating temperature is set at 60-70 ° C.

Devices of the TERMEKS trademark are highly respected by consumers. It cannot be argued about their complete identity with other brands, but the construction and principle of operation of the units are very similar. Also, the designs of flow-through and storage heaters are the same, the former differ only in a more powerful heating element, the latter have a large tank. Therefore, having analyzed the main reasons for the breakdown of the Termeks water heater, it will be much easier to repair any other model yourself.

The most problematic part of a water heating device is its internal capacity. It is made of stainless steel or coated with titanium enamel. Stainless steel serves for 10 or more years, the enamel deteriorates twice as early. Tank leaking is often fatal to further use of the heater. In most cases causes of malfunction of the water heater and its leaks lie in the corrosion of the bulb. Manufacturers protect it by spraying various compounds and installing a magnesium anode, but this rarely saves. Sometimes it is possible to weld the container with argon, otherwise it is impossible to repair the unit. Therefore, timely replacement of the magnesium anode and annual descaling of the tank is so important.

There are various malfunctions of water heaters, which are identified and eliminated on their own:

When turning on the device knocks out the RCD... Possible incorrect connection of the heating element (check), incorrect connection of the equipment to the power supply (check) or failure of the machine (replace).
The water heater does not heat water. The thermostat (check, replace) or heating element (check, replace) could be out of order or poorly connected. The device is not well connected to the mains (check).

Leaking from under the flange. The gasket was worn out or damaged (remove and look for a similar one - it is better not China), the flange itself is rusted and leaks (replace).
Temperature not regulated, heater overheats (boils) and turns off... It talks about the failure of the thermostat (check the thermal paste under it and the device itself, replace it) or incorrect connection of the device (check).
The device does not heat up at all or too heats the water slowly... Happens due to breakdowns thermostat water heater (replace), excessively scaled or burned-out heating element (clean, replace), failure of the control and monitoring unit (call the master, replace).

Water heater housing electrocuted... The heating element is covered with scale, cracked and the water contacts the coil (replace) or the control and monitoring unit (replace) is out of order. The device is not grounded (ground).
Unit does not turn on... The thermostat does not work (replace), the heating element has shorted or burned out (replace), the control board is out of order (replace), the mains power is not supplied (check).
The device hisses, heats up for a long time, makes extraneous sounds. The phenomenon is observed when installing pipes that are too narrow (replace with wider ones). If the heater is used for a long time without preventive measures (clean it).

There are others malfunctions of electric water heatersspecific to certain models. Ways to eliminate any of them can be found on the Internet upon request.

The main causes of boiler breakdown the same ones that disable water heaters (scale), although in these devices an important role is played by the fittings of devices: pipes, connections, taps, valves, valves, pumps. Here, the inner areas of the tanks are also prone to the formation of deposits, but most of them accumulate on the inner and outer surfaces of the coils (depending on what acts as a coolant). Frequent enough boiler breakdown - failure of its conductive tubes. Their welding is possible only with argon, but to carry out such a repair, you will have to remove the coil from the tank, and then hoist it back. Repair on your own is almost impossible here and contacting the service is inevitable.

It is difficult to imagine comfortable living conditions without hot water supply. Nevertheless, you will hardly surprise anyone with systematic interruptions in the supply of hot water on schedule or without a schedule. Tired of enduring the temporary lack of hot water in a city apartment, doing without a warm shower in your country house, or just wanting to improve your life in a private house? All these problems are solved by an elementary installation of a flow pipe or a boiler. One provides an uninterrupted supply of water when needed, and the other, solving a similar problem, will also help to save on paying electricity bills.

Currently, there are a huge number of brands engaged in the production of instantaneous water heaters. The Israeli brand Atmor enjoys a good reputation. The instantaneous water heater produced by this company has good performance indicators, is convenient and safe to use. Features of Atmor water heating equipment, installation instructions, DIY repairs and customer reviews - read about all this below.

When you need to buy large household appliances, you always want the choice to be right. It is for this reason that one should carefully study the performance characteristics of the offered products.

As for the choice of heaters, here you should first of all pay attention to the power of the device, which affects the pressure force, the number of serviced parsing points, and the installation option.The best option is a 5000 W device. If a storage water heater is required, then the tank capacity is added to these parameters.

It is equally important to understand the difference in the principle of operation of both types of water heating devices. Instant heating of a cold stream with flowing equipment is carried out by equipping such devices with heating elements. When the heating element is turned on, it starts to heat up. As a result of water jets hitting the heating element, they almost instantly warm up to the temperature parameters set by the user.

That is, as soon as you open the tap, you can already start using hot water. Without using a special tank, like in boilers, where within an hour or two the water will gradually warm up to the desired temperature, it is not necessary in principle to wait for the "readiness" of water with a running water heater.

The advantages of Atmor flow-through devices, which are distinguished by a well-thought-out design solution, can also be safely attributed to the following:

Compact dimensions of the equipment - due to their small size, the devices do not require much space, plus they are quite lightweight.
They work properly even with prolonged interaction with poor quality water.
Equipping with special tubular heating elements up to 12,000 W provides a high speed of water heating.
Quality materials and workmanship.
A protective mechanism is provided to automatically shut off the water flow in case of overheating over 50 ° C. A thermal fuse helps prevent heat burns.
Electricity consumption occurs only when water is used directly.
The new models of water heaters have a display and a function of smooth adjustment of the heating temperature.
Long-term operation - subject to the manufacturer's recommendations, the Atmor water heater will delight you with uninterrupted operation for 10 years or even more.

Instantaneous water heaters Atmor (Israel)

As for the disadvantages of Atmor water heating equipment, the following points can be highlighted:

Difficulties often arise when replacing a non-standard shower hose.
To connect the heater, a separate line must be drawn from the electrical panel. Although this requirement applies to the use of any instantaneous water heaters, regardless of the manufacturer.
The supplied mounting templates are far from always suitable, so the easiest way is to calculate by yourself where the holes for the fasteners will be located.

The wide range of products of the Israeli brand allows you to choose a compact device that will become a reliable assistant at the height of the summer season or more powerful for organizing hot water supply in homes with permanent residence.

The model range of Atmor water heaters is represented by several series of flow-through and storage-type water heating devices:

Storage heaters with a capacity of up to 30 liters. Indicators of power consumption are 1500 W, and the maximum heating temperature is 85 ° C.

Allows you to choose a flowing electric heater that complements the shower. The popularity of the BASIC models is due to the affordable price of 2200 rubles.

Atmor Platinum 5 kW (Crane)

Universal grooves. Platinum models are equally suitable for seasonal and permanent use both in summer and winter.

Heater models ideal for outdoor showers or kitchens. The maximum heating temperature is 65 ° C, the rated power is 3500 W. The set of devices includes a faucet nozzle and a shower head.

Atmor Blue Wave 405 Thermostatic

Water heaters of different power 5 kW, 7 kW with a productivity of 3 and 4 liters of water per minute, respectively.

ATMOR Aquaplus Supreme 5 kW Shower

Universal heaters with a power of 5000 watts.

These are the possibilities to choose a flow-through water heater with a capacity of 5 kW, 7 kW and 12 kW, where a water discharge system through a flow-through valve is provided. In addition, such models are integrated into the general water supply system, and the resulting water can be distributed among several points of analysis.

A series of models with a water gradual changeover mechanism. Any Optima model will cope with the task of supplying hot water for household needs.

The official website of the Atmor manufacturer contains detailed information on each model range, so when planning to buy a water heater, do not forget to study the technical characteristics of the models and compare prices from official dealers.

The compactness and low weight of Atmor devices greatly simplifies the task of their installation. It is enough to choose any free and convenient corner in the kitchen or bathroom, and you can immediately start installation. Although, in some cases, it will not be possible to install a water heater, even following the instructions, for a number of reasons.

Flow-through units have increased requirements for the parameters of the electrical network, which implies the need for an appropriate powerful, three-phase electrical wiring. Moreover, the electricity meter must withstand a load of over 40 amperes, otherwise it will need to be replaced. The same situation is with old pipes or the lack of appropriate connectors on them. That is, it may also be necessary to modernize existing communications.

If such issues do not have to be solved, then other difficulties should not arise. So, the installation of a water heater includes:

The choice of the optimal place where the structure will be located, so that it is not only convenient to use the heater, but also provides easy access to all points of the water intake.
Layout of the unit fastening diagram. If the walls are concrete, it is best to use a hammer drill to drill holes of the required diameter.
Connecting the water inlet / outlet.
Power supply connection. First you need to make sure that there are no leaks in the system.
Done: after 15-20 seconds you can enjoy hot water.

There are two options for connecting a water heater. Temporary use of a water heater involves the supply of cold water. A shut-off valve and a flexible hose are installed on the corresponding pipe, which is connected to the water heater. With a permanent connection, in a cold and hot pipe, it cuts through a tee with a shut-off valve. After that, both tees will remain connected to the corresponding holes of the equipment, and connect the tap and the water outlet with a hose.

In the absence of self-confidence, it is better to seek help from specialists. In addition, if the Atmor water heater is installed by professionals, warranty maintenance will be a bonus.

Over time, any, even the highest quality and most reliable equipment can fail. The Atmor flow-through electric water heater is no exception. Failure of heaters is often the result of low pressure inside the system, improperly selected water heating capacity, given the need to maintain several points of analysis. In such a situation, devices experience increased loads for a long time, working at the limit of their capabilities, which provokes premature wear of parts and a subsequent malfunctioning state. Repair is indispensable.However, the simple design of the Atmor water heater should not be misleading: setting up electronic components is a delicate matter, and they did it in production conditions. At best, attempts at unskilled intervention will ultimately "kill" the pipe, and at worst, they will cause a fire or electric shock.Self-replacement of rubber gaskets for flexible liners, cracked due to constant interaction with a hot stream of water, is the minimum that excludes negative consequences for water heating and your own health.In addition to positive reviews about Atmor water heating equipment, there are also negative opinions from the owners of the products of the Israeli manufacturer. If we summarize the impressions about the operation of the devices, then the conclusions will be as follows:Positive reviewsNegative reviewsCompact size of devices, which is fundamentally important for owners of small-sized apartments who have to constantly look for alternative solutions in the face of a shortage of precious squaresInsufficient water heatingThe ability of low-power devices to perfectly cope with the responsibilities assigned to them. This applies to seasonal use in summer cottages and during interruptions with hot water supply in city apartments.When distributing water between several points of parsing, the devices begin to malfunctionPowerful water heating equipment becomes a full-fledged alternative to hot water supply in the absence of it in private households where people live permanentlyDifficulty installing a heater or replacing parts (see repairing a water heater)Moderate consumption of electricity by water heaters with a capacity of 7 kW and 12 kW, many consider such a consumption not burdensome in terms of paying for electricityDespite the existing disadvantages, the Atmor water heater can be safely called a convenient and reliable household appliance. The main advantage of the Israeli manufacturer's equipment is its high quality and affordable price. Subject to the correct choice of equipment and proper installation, such devices will be able to please with trouble-free operation for a long time.VIDEO: What is better to choose - instantaneous water heater or storage

Figure 1. Diagram of an electric storage water heater.

To understand how you can repair electric water heaters with your own hands, you must first determine the causes of the breakdown.

For this, we will pay special attention to electric storage water heaters. If you figure out how to determine the cause of the malfunction, it will be easy for you to determine it for both gas and instantaneous water heaters.

So, we begin to learn to look for the cause of the breakdown of an electric water heater.To do this efficiently, you need to act step by step. To do this, consider the process of troubleshooting in turn order for storage and instantaneous water heaters.

Voltage check. As a rule, voltage is applied to the electrical installation at the terminals of the thermal relay. To check the functionality, it is necessary to check the presence of voltage with the device.

Figure 2. Diagram of a gas storage water heater.

Then disassemble the thermostat. Inspect the wires for oxidation and damage. You can clean them if necessary.

Then take an ohmmeter and use it to check the device again. If the problem is really in this mechanism, then you will definitely see the reason. If you find that everything is in order with the voltage, proceed to the next stage.

Checking the presence of a short circuit in the circuit. This can be connected both with the thermal relay, and completely with the entire current supply chain. To check for a short, set the thermostat to positive. Now make sure that all contacts are closed, then connect an ohmmeter. If everything is in order, the instrument will indicate the presence of negligible resistance. But if it is absent, this indicates an open circuit and a malfunction of the thermal relay or an adjacent circuit.

Opening check. To do this, set the arrow of the thermal relay to minus. After that, light a match and bring the thermostat to the flask. If it clicks and turns off, then everything is in order. If there is no response, a malfunction of the thermal relay can be identified.

Checking the health of the heating element - heating element. To do this, measure the resistance at the heating element using an ohmmeter. In the event that it is equal to infinity, the heating element must be replaced. If everything is in order, check the resistance between the heating element and the flange in the same way. With a very weak value, either the flange or the heating element must be replaced.

Figure 3. Diagram of a ceramic heating element.

So, having considered the main steps for identifying a malfunction in the electrical part of the boiler, it becomes clear that the main causes of malfunctions may lie in the thermostat or in the heating element. If you know for sure that a replacement is required, you can purchase a new item right away. In all other cases, specialist advice is needed, especially if you do not have the skills to work with electricity.

It should be noted that the same step-by-step troubleshooting diagnostics is suitable for both storage electric water heaters and instantaneous water heaters. Therefore, the repair of instantaneous water heaters is very similar to storage water heaters.

These were the main points concerning the electrical part of the water heater. It is also advisable to consider, using a specific example, how the repair of the working part of a clogged electric water heating tank or gas water heater is carried out.

So, first we shut off the code and electricity. After that, carefully remove the water heater from the hooks on the wall, put it on a flat surface and unscrew its lower part. Now we disconnect all the wires adjacent to the heater, and at the same time remove the thermostat by unscrewing it from the nuts and terminals.

Mechanical thermostat diagram.

Now remove the thermostat from the device and take a close look: if the tank has not been cleaned for more than two years, you will see a lot of dirt there (Figure 1). To get rid of it, just rinse the thermostat under running water, wipe it dry and dry it well. If the heating element still looks pretty bad after rinsing, it's best to get a new one right away.

Additionally, you can buy in advance an anode that you install in the tank for reliable protection if the anode previously located there has become unusable. But in order not to waste money, after unscrewing and rinsing the elements, it is best to show them to a specialist and listen to what he advises you.

During this time, you will need to thoroughly clean the container itself inside the tank. It is better to do this outdoors with a hose, since the bath will then have to be cleaned for a long time from rust and scale accumulation. To clean it, put the water heating tank on its side and rinse the dirt out of it with a strong jet of water.

To do this better, you can use a not too hard brush, with which it is good to clean the walls of the tank. After that, rinse it well and dry it upside down so that all the water is glass.

After everything is ready, you need to reassemble the tank and hang it on the wall. This does not require special skills and abilities. But if you doubt the correctness of the steps, even during disassembly, make notes for yourself where to insert and screw.It is necessary to start assembling storage water heaters by screwing the heating element to the bottom cover. Just make sure it is level and the screws are tight enough (Figure 2). When doing this, do not forget to put a new rubber gasket between the heating element and the small base cover. It is she who serves as the main hermetic sealer of this design. Now we connect all this together with the help of screws and nuts, trying to do the work so that there are no distortions. As a result, the bottom will look something like this (Figure 3).
