Eureka Maxima Canister Vacuum 972B Reviews – Viewpoints.com

3 reviews

This vacuum is very powerful for it’s size. It’s great for hardwood, tile and stairs. It is very lightweight and easy to move from room to room. It does not have a rotating brush, however, so is not good on carpet. It gets the surface dirt only. The cord is VERY short and must be plugged and unplugged for every room. It is automatic, though, and goes back into the machine with the push of a button. I got only a little brush with mine, but called customer service and they sent out a very small crevice tool right away. There is only a place for 1 tool to be stored on the machine, however.

This is my 2nd Eureka vaccum cleaner. ..the first one had it for over 15yrs.
Gave it away…so I bought a more update one. And I LOVE it.
Great on wood floors and tiled flooring. It is very strong for being such a little compact unit.
It’s has a Euro Design…modern but simple. One of the things I really liked was the
design of the wand…you can ajust the length. It also has a two pedals..one to turn it on….other to retrieve the electric cord.
Comes with a combination floor tool…by pushing the lever it ajusts to carpet or bare floors.
I really believe that for the money….this vaccum is so worth every penny.

We have two dogs and a cat and hardwood floors throughout much of our house. We also have a year old child, so cleanliness on the floor is particularly important. I’m a busy work-at-home mom, so I need something lightweight to clean up the floors very quickly and very easily every day. I’m not the most motivated person when it comes to housecleaning, so I need things that are really easy to use and allow me to get it done super fast.
My husband got this little canister vac for me and even though it wasn’t what I thought I needed, it ended up being perfect. It’s light, long telescoping wand allows me to get under our huge sectional sofa as well as under the dining room table easily to get up dust, dog hair, crumbs and even the odd goldfish cracker. I don’t even have to move the dining room chairs because the wand swivels. It’s great. It’s very lightweight and the wheels roll easily so I can move quickly through each area of our great room space. I can clean the kitchen, laundry room, dining room, living room, foyer, two bathrooms, the hallway and nursery in about 15 minutes. It cleans great on ceramic tile as well as the hardwood (both prefinished – gets down in the cracks and traditional wood flooring as well. ) I was looking for a cordless stick vac but it turned out that this little canister is what I actually needed. The stick vac wouldn’t have done everything I can do with this, like get under furniture.
It’s not perfect, but I don’t have many complaints. The main attachment to clean the floor is made of flimsy plastic so it might not hold up over time, but we’ll see. The cord is way too short, but I should’ve known because I’ve bought other Eureka models with the same issue. It’s not a deal breaker for me, but a longer cord would be nice, as I have a pretty expansive space to clean. My only other complaint is that it uses bag instead of a canister that you empty. I don’t know much about canisters since this is the first I’ve ever owned so maybe they’re all this way, not sure. It comes with a handful of replacement bags, which is nice and they’re pretty inexpensive so that’s not a big deal. It doesn’t do a great job on carpet, but that’s not what I bought it for. I still intend to use my big full-size upright vacuum for the carpeted areas.
All in all it helps me get my daily floor cleaning done quickly, effieciently and effectively. I would recommend this product to someone with similar needs.

Answer

beta-pozytron, what do you say to that?
“”One of the main characteristics of celestial bodies is the second space velocity – this is the minimum speed that must be reported to the spacecraft in order for it to break away from the planet into free space. It is easy to derive a formula for calculating the second space velocity: the kinetic energy of the body must be no less than the energy of gravitational attraction:
mv2/2 = GMm/r
v2/2 = GM/r
Accordingly, the second space velocity is defined as follows:
v2 = 2GM/r
For all known celestial bodies, the second space velocity is much less than the speed of light: for example, Earth – 12 km / s, for the Sun – 435 km / s. However, in the course of the evolution of stars, they can reach a state in which their escape velocity will approach or even exceed the speed of light.
Most of the stars during most of their lives remain stable in size due to the fact that the huge force of gravitational contraction is balanced by the force of thermal and light pressure generated by thermonuclear reactions in the interiors of stars. But when the reserves of nuclear fuel in the stars are exhausted, then nothing balances gravity, and the star begins to shrink.
If the mass of the star does not exceed one and a half masses of the Sun, then the compression of matter inside the star ends at the stage when the core of stars turns into a white dwarf (with a mass close to the mass of the Sun, their size is approximately equal to the size of the Earth – the density of matter in white dwarfs can reach up to tons in a cubic centimeter), and the outer shell expands (which looks like a red giant star from the outside) and gradually “dissolves” in space. It will be the same with the Sun.
If the mass of a star is in the range from 1.5 to 2.5 solar masses, then the compression of the matter in the star reaches such a state that the electrons in the atoms are “pressed” into the protons, only neutrons remain in the star, attracted to each other by nuclear forces . The star begins to look like a giant atomic nucleus. It’s called a neutron star. Its dimensions are only a few kilometers, and the density of matter is the same as in the atomic nucleus – 1012 – 1014 grams per cubic centimeter.
However, both white dwarfs and neutron stars have a second cosmic velocity less than the speed of light.
But for stars with a mass greater than 2.5 solar masses, compression cannot be stopped by any of the currently known forces, and they can shrink to such a small size that for them the second cosmic velocity becomes higher than the speed of light. This means that light cannot escape from this star. Such a star absorbs light, but does not release it back. For an external observer, such an object looks like a “black hole” in space. The term ‘black hole’ in relation to such objects was introduced by J. Wheeler in 1968 year. For the first time such objects were predicted back in 1801 by the famous astronomer Laplace, but interest in them appeared only a century and a half later, after the discoveries of the general theory of relativity and cosmology.
The concept of gravitational radius is associated with black holes. Recall the formula for the second escape velocity: v2 = 2GM/r. If the second space velocity is equal to the speed of light (v = c), then the “critical” distance is equal to rg=2GM/c2. For none of the celestial bodies, we can not say what happens inside its gravitational radius, because light cannot go beyond it. For example, the gravitational radius for the Earth is 9millimeters, and for the Sun – 3 kilometers. These are negligible values in comparison with the sizes of these bodies.
But for black holes, the gravitational radius is greater than the real radius of these bodies. Therefore, any body or substance, once inside the gravitational radius, seems to “disappear” for an external observer.
Since the theory of relativity states that the speed of light is the maximum possible, the conclusion is drawn from this that matter, having fallen into a black hole (or, what is the same, having fallen inside the gravitational radius) completely disappears, since it cannot either return back or give signal of its existence. Therefore, from the assumption that the speed of light is the maximum possible, the statement follows that if matter can disappear without a trace, which contradicts the generally accepted principles of materialism.
The theory of relativity puts forward various artificial resolutions of this contradiction. It has been suggested that when approaching the gravitational radius, time slows down, and for an external observer, the approach to the gravitational radius takes infinite time (therefore, for an external observer, matter does not seem to disappear). Very dubious assumptions were also made that black holes are special points in space-time and even almost transitions to other Universes. Hypotheses were put forward that black holes can still be connected with the external environment – through the gravitational interaction (but this required recognizing that the gravitational interaction propagates faster than light, which contradicts the theory of relativity). Finally, Einstein himself honestly admitted that, in his opinion, such celestial bodies as ‘black holes’ do not exist [1], because if one admits their existence, then one thing – either the theory of relativity or materialism – does not exist. right. Einstein, of course, did not want to recognize the theory of relativity as incorrect, but he also did not risk openly infringing on materialism.
However, at the end of the twentieth century, black holes were discovered experimentally. If we assume that black holes are capable of gravitational interaction, then in binary systems consisting of an ordinary star and a black hole, gas can flow from one component to another. In the gravitational field of a black hole, the gas will move along spiral trajectories and get very hot (up to temperatures of the order of 10 million degrees). In this case, powerful X-ray radiation should arise, the intensity of which changes rapidly with time. At 19In the 80s, real space objects were discovered that could claim the title of black holes – this is the object SS 433 in the constellation Aquila and the invisible satellite of the star HDE 226868 in the constellation Cygnus. This satellite has a mass of about 10 solar masses and a rotation period of 5.6 days. In the 1990s, it was established that black holes exist in all the nuclei of galaxies, as evidenced by the constant background of uniform cosmic X-ray radiation, which is similar in its properties to relic radio emission.
Observations of black holes made it possible to establish the following:
1) black holes (that is, objects whose mass and radius allow us to assert that their second space velocity is greater than light) really exist
2) black holes can be fixed by their gravitational interaction – that is, gravitational the field is able to penetrate the gravitational radius
3) the statement of the theory of relativity about the slowing down of the flow of time as it approaches the gravitational radius does not correspond to reality – otherwise the process of falling matter into a black hole for an external observer would look like a cloud of gas around a black hole, the density of which becomes infinite as it approaches the gravitational radius, which is clearly not observed.
Thus, the fact of detection and observation of black holes indicates that the propagation velocity of the gravitational interaction exceeds the propagation velocity of the electromagnetic interaction (the speed of light). In other words, the experimental discovery of black holes is an argument against the theory of relativity. Estimates given in 36 show that the speed of propagation of the gravitational interaction should not be lower than 105 speeds of light
Additions.
1. Interestingly, besides ‘black holes’, other bodies are also possible that interact with the surrounding space only through gravitational interaction. Such particles are called WIMPs (more about them in 36). All the oddities in the behavior of such particles can be explained if we assume that they move at a superluminal speed. Thus, after this class of particles is discovered, this will be another evidence in favor of the fact that, firstly, the gravitational field propagates much faster than light and, secondly, there are material bodies that are also capable of moving at superluminal speed. .
2. In 2005, material was published on the Internet, indicating that the existence of black holes contradicts the theory of relativity. It says, in particular, the following:
‘Until now, it was believed that black holes are one of the most convincing confirmations of the correctness of Einstein’s general theory of relativity, according to which gravity is nothing but a property of space-time deformed by massive bodies. True, Einstein himself, points out George Chaplin, did not believe in the existence of black holes. “Unfortunately, he didn’t explain why,” Mr. Chaplin says. The root of the problem, apparently, is in quantum mechanics, another revolutionary theory of the twentieth century, in the formation of which Einstein also took a direct part.
From the point of view of general relativity, there is no ‘universal time’ in the universe. Moreover, the speed of the clock, generally speaking, is not constant and depends on where they are. At the same time, quantum mechanics, as George Chaplin points out, makes sense only if universal time does exist, otherwise its apparatus is simply inapplicable.
In particular, the glaring divergence of the two theories appears when trying to describe the physics of events occurring around the so-called ‘event horizon’ of a hypothetical black hole. To a distant observer, it will seem that time has practically stopped here. But for the crew…””

Water heater FAQ

Objections

Are the tanks safe when the water heater is in constant use?

The internal tanks of ARISTON water heaters are quite reliable, because have a double margin of safety: the working pressure is 8 atm., while the pressure during testing is 16 atm. Reliability also depends on the coating of the steel inner tank of the water heater. ARISTON uses finely dispersed and titanium (exclusive development of the company) enamel, which protects the tank from corrosion for the entire service life. When it comes to stainless steel tanks, the durability largely depends on the grade of steel. On the Russian market today there are EVN tanks made of the following steel grades: 301, 304, 439, 316L, etc. The highest quality and most expensive stainless steel is INOX316L. This grade is used in the manufacture of medical instruments, has improved corrosion resistance with lower carbon for welding, as well as higher elongation and hardness. It is this brand that is used in the production of Ariston Platinum and Steel Tronic EVN lines. Also, the strength of the tank depends on the quality of welding, because. welds are the tank’s weakest point, where leakage and corrosion can occur. ARISTON uses only high-tech types of welding: argon-arc and plasma. These welding technologies are the most effective way to protect seams.

Which water heaters consume more electricity: storage or instantaneous?

Storage water heaters consume relatively less electricity than instantaneous water heaters. Thus, a water heater of the TiTronic series with a capacity of 80 liters consumes only 4.5 kW of electricity for 3 hours of heating water, while you get 80 liters of hot water (75 ° C) and twice as much (160 liters) of warm water (40-45 ° C). C), as you dilute it with cold water. Instantaneous water heaters with a capacity of 4.5 kW per hour will heat only 120 liters of warm water (35-40 ° C), while the temperature at the outlet of the instantaneous water heater, as a rule, is not the same due to voltage fluctuations in the network and water pressure in the line. After heating in the storage water heater, the water retains all the heat, because ARISTON water heaters have excellent thermal insulation. You can use this hot water for one or two days.

EWH device, principle of operation, assembly technology

How is enamel applied?

Enamel powder is applied according to the principle of the difference in electrostatic charges (as if attracted to the walls of the inner tank), which in principle eliminates the formation of bubbles, bumps and cracks. The tank is then heated to a temperature of 850°C, whereby the enamel coating is melted and sintered with the material of the tank.

Why do you need a magnesium anode if you said that the tank is covered with titanium enamel?

Magnesium anode is an additional protection of the tank against corrosion. Only in ARISTON water heaters is an oversized magnesium anode, that is, the life and protection of the tank is much longer than in other water heaters.

How do you save energy?

Electricity is saved due to the thermal insulation of the tank made of dense polyurethane foam, which provides a daily heat loss of an 80-liter water heater of about 1 kW.

What is the maximum working pressure in the tank?

Maximum operating pressure – a value that characterizes the ability of the water heater to withstand water pressure. The maximum working pressure is 8 atm. If the pressure in the tank rises above 8 atm, then the safety valve is activated.

What is the wall thickness of the stainless steel tank?

Stainless steel tank wall thickness from 0.6 to 1.3 mm depending on the model.

What is stainless steel passivation?

Special chemical treatment of the tank – a “passive” to oxygen film is formed, which prevents oxygen from reaching the walls of the tank. From the point of view of corrosion, passivation is the formation of an inert film on the metal surface, which slows down the corrosion of welds, since ordinary metal is used when welding the joints.

The passivation process is only used for stainless steel tanks, as in steel tanks double corrosion protection: enamel coating and magnesium anode.

What is the capacity of ARISTON storage water heaters?

The power of the heating element, depending on the model, can be 1.2; 1.5; 2.0;3.0 or 6.0 kW. This information is contained in catalogs, booklets, instructions.

How quickly does the water heat up in the storage EWH?

Depending on the volume of the apparatus and the power of the heater: from 20 minutes to 5 hours. For example, a TI-Tronic Best series water heater with a capacity of 80 liters heats up in 3 hours and 6 minutes.

How many heating elements in EWH of large volumes?

All EWH uses one heating element.

Construction and material of thermostat?

In models 30SLIM and 50-20 l we have bimetal thermostats. They work on the difference in thermal expansion of metals: shell and rod. Temperature error up to 5-7 degrees.

In 10-3 L and Ti Shape small displacement models, we use capillary thermostats, more accurate, error up to 3-4 degrees.

Ti-Tronic BEST thermostat is electronic, the most high-precision, the error is 1 degree, the principle of operation is the different resistance of the material at different temperatures, when the temperature changes, the resistance value changes and is fixed by the control board.

What is inside the heating element?

Inside the copper sheath is a nichrome helix. The spiral is isolated from the walls of the shell by a compressed dielectric filler having a high coefficient of thermal conductivity. To protect against moisture ingress, the ends of the heating element are sealed.

What is the temperature and volume of water obtained at the outlet of the flow EWH? Does the heating element coil affect the heating in the flow EWH?

Any flowing EWH with a power of 3.5-7 kW gives 2-4 l / min of water heated by 25 ° C compared to the inlet temperature. For example, with the help of a flow-through EWH, filling a 150 liter bath with warm water will take about an hour.

Yes, it does. The spiral is made of high ohmic wire

How does the safety thermostat work?

If the temperature control is not carried out correctly, the temperature in the water heater can rise significantly and lead to the formation of steam!

To avoid this, an independent safety device will cut off the supply voltage. The restart is done manually. Before manually restarting and restarting, the cause of the safety device operation must be determined.

To what temperature is the water heated in the storage EWH?

Up to 80°C maximum (up to 75°C on models with mechanical thermostat). However, in order not to form scale on the heating element (heater), the heating temperature should be set to 60 ° C, because at temperatures above 61 ° C, intensive scale formation begins.

What is the difference between open and closed circuits?

In an open circuit, overpressure is compensated according to the law of communicating vessels, i.e. there is no pressure in the tank. To connect water heaters of the Evrika series, only an open circuit is used. On Eureka, a valve is installed at the hot water outlet. The valve is triggered when there are problems with the exit of water from the shower head (nozzle blockage, etc.). In a system with a closed outlet, excess pressure is compensated by a relief valve, which is also a safety valve that prevents water from escaping from the EWH through the cold water inlet pipe.

What is TIG welding and how is it different from vacuum welding?

In argon-arc welding of seams, an inert gas argon is used, which displaces oxygen by 100%, that is, no oxidation occurs. Welding in a vacuum is not so reliable, because. it is impossible to achieve absolute vacuum in terrestrial conditions, i.e. the oxidation process is still going on.

Volume selection

I have very soft water in my house. Does this affect the operation of the water heater?

Soft water can accelerate the corrosion of the tank, so you’d better buy a water heater with a stainless steel tank (PLATINUM series) or a plastic tank (EUREKA series).

How many people can wash Eureka series EVN?

The volume of the water heater of the Eureka series (13 liters) is enough to quickly wash one person, but due to the powerful heating element (2 kW), the water will heat up again in just 20-25 minutes.

How much warm water is produced by mixing?

Since hot water is mixed with cold water, the volume of warm water from the tap will be approximately twice the volume of the water heater. For example, a 50 liter water heater will give you 100 liters of warm water (40°C – 45°C) – enough for several people to wash.

I have a small bathtub, how do I put a water heater in it?

ARISTON offers a wide range of water heaters of various sizes and designs. I would recommend you the TI-SHAPE SH QB 40 or 50 liter model, it is an excellent model of the SLIM series with a narrow diameter and a unique design that can be installed even in a small bathroom.

Benchmarking

Why is the PLATINUM series water heater more expensive than the SUPER GLASS series even though the tank capacity is the same?

In PLATINUM series water heaters, the tank is made of stainless steel. It has a 7 year warranty. Tanks made of stainless steel are more reliable and durable, and, accordingly, more expensive than steel tanks with an enamel coating. In water heaters of the SUPER GLASS series, the steel tank is coated with finely dispersed enamel and has a 3-year warranty.

What is the difference between ARISTON and Electrolux EWH?

All models of Electrolux water heaters have a tank with a fine enamel coating, while the guarantee is given for only one year. Several types of tank coatings are used in ARISTON water heaters, in addition, tanks are made of stainless steel, respectively, the warranty period has been increased from 3 to 7 years. In Electrolux water heaters, the heating element (TEN) does not interact with water, the so-called “dry” TEN, this presents a certain convenience when removing it, but, on the other hand, leads to an increase in heating time and energy consumption.

Why is ARISTON stainless steel better than Thermex stainless steel?

Based on our laboratory analysis, Thermex uses 301 or 304 steel grades, one of the characteristics of which is intergranular corrosion. This type of corrosion leads to embrittlement of the material along the grain boundaries of the metal during operation. ZAO Real-Termo (Real water heaters) came to a similar conclusion.

Water heaters are designed to operate at pressures up to 8 atm. Such a loaded state should be provided by materials that work well within the limits of elastic deformation.

ARISTON uses 316 stainless steel, which belongs to the grades that are especially resistant to corrosion and aggressive environments, and, accordingly, are more reliable and durable.

EWH models, which can be placed both vertically and horizontally, are very convenient for sellers, other manufacturers have them, why doesn’t Ariston produce such models?

Models that can be positioned both horizontally and vertically are convenient, but lose functionality. In a horizontal arrangement, not the entire volume of EWH is used? Mountain mixing zone. and hol. more water than in the vertical EWH. The horizontal arrangement is rarely used (a small percentage), and if the model has a universal arrangement, this increases the cost of the product. Conclusion It is not advisable to produce such models

Safety, reliability

Can the tank explode if overheated?

All ARISTON water heaters are equipped with several safety devices. This is a thermostat that regulates the temperature of the water in the tank; safety valve protects the inner tank from excessive internal pressure; The overheating thermostat is activated in the event of a malfunction of the main thermostat.

Are water heater materials safe for health?

One of the priorities of the water heater manufacturer ARISTON is the protection of health and the environment, i.e. use in the production of only safe and environmentally friendly materials.

I have small children. Will the water heater be dangerous for them?

ARISTON water heaters are absolutely safe, including if there are children in the family: the devices have 3 degrees of protection that make the water heater reliable in any situation. In the event that the child even turns the temperature regulator, the maximum temperature can be set to 80 degrees, which is the operating temperature for the device. The possibility of a child’s burn is completely excluded, because. the outer casing has an ambient temperature, and penetration into the tank is impossible: the design is sealed.

How is the tank leak tested?

Testing takes place in a special pressure bath 16 bar

What kind of high pressure protection is provided?

In addition to the strength of the inner tank, made of high-quality steel, all models of ARISTON water heaters are protected against high pressure: the safety valve at the inlet will not allow the pressure in the tank to exceed 8 atm.

Will the bolts on the flange not loosen under water pressure?

The type of bolts used ensures that the flange is secure and tight, as well as easy to operate when removing internal parts in case of cleaning or replacement.

How is quality control carried out?

Quality control takes place at every stage of production. Constantly there is a modernization of technological processes, as well as thorough testing of finished products. The prestigious Corporate Certificate Europe confirms the highest quality of the company’s products.

Warranty

The tank is guaranteed for 3, 5 or 7 years, what about the warranty for the rest of the internal parts?

Warranty for electrical components is 1 year.

How will the guarantee for the tank change if the EWH has been replaced by SC employees?

The warranty for the tank will be reported from the moment of purchase of the failed EWH.

What is the service life of EWH?

Depending on the series from 5 to 7 years. Basically, the service life coincides with the warranty period.

Why is the TyTronik Best warranty higher than the TyTronik Mechanic?

Tai Tronic Best series water heaters use a unique electronic thermostat that allows you to set and control the temperature with greater accuracy, and therefore does not overheat the water, which increases the life of the internal tank.

What is the weakest point in the inner tank?

The weakest point is not even the seams of the tank, but the area between the seam and the tank, because when heated and cooled, places in this area are most susceptible to deformation. To protect these places in stainless steel, a passivation process is used.

Installation, maintenance, service

Is the storage water heater affected by low inlet water pressure or low electrical voltage?

No. The water heater can even work in a country house with a water tank installed directly above the unit. Water flows by gravity and that’s enough. If the voltage is lower than usual, then the water heater will heat the water anyway, only it will take a little longer.

How fast does the water in the Eureka water heater cool down?

The water cooling time is calculated using the formula Q1? Q2 where, Q1=CM?T are the required heat losses for cooling to a certain temperature, (where C is the specific heat capacity of water, M is the mass of water, ?T is the difference between the initial and final temperatures). Q2=Const – heat loss per hour (value given in the catalogues).

Thus, a water heater of the Evrika series with a water temperature in the tank of 60 ° C will cool down to room temperature for about 6 hours.

Is it possible to drain all the water from Eureka?

Yes, you can. The instructions show in detail how to do this.

I have high water pressure, will this damage the water heater?

If the pressure in the network is above 6 atmospheres, it is necessary to install a reducer to reduce the pressure in the water supply.

What should be done if the water from the non-return valve does not drip, but flows in a jet?

In all likelihood, the pressure in the water supply is higher than 6 bar, so a reducer is required to reduce the pressure in the water supply. The non-return valve may be defective. I recommend contacting the service center: specialists will quickly and professionally solve your problem.

When using tap water, scale forms on the walls of the tank and heating element. What should be done in this case?

Scale on the walls of the tank serves as an additional protection against corrosion, but the heater must be cleaned once a year or every two years, depending on the hardness of the water. You can do this with our authorized SCs.

Hard water increases scale in the water heater. How to prevent it?

You can reduce the formation of scale with a filter dispenser that softens the water if necessary. The dosing filter is installed in front of the cold water inlet to the water heater.

I need a water heater only for the summer season at the cottage, can it deteriorate during the winter?

Low temperatures do not affect the condition of the water heater. After the end of the summer season, the water from the water heater must be drained to prevent damage to the tank when the water freezes.

I would like to purchase a water heater of the EUREKA series for a summer house for a shower. Do I need to empty the water tank if I’m away for a week?

No, it is not necessary in the summer, it is enough to disconnect the water heater from the power supply. However, in winter, the water must be drained.

Do I need to use a grounding plug for the flow EWH?

Required, as for all electrical appliances.

Do I need to change the gasket when removing the flange? Where can I get it?

Replace as needed (visible damage, etc.). You can buy it at the service center.

What kind of EWH maintenance is required?

Once a year or once every two years, according to the instructions, remove the heating element, clean the scale and check how much the magnesium anode has “eaten”. It depends on the hardness of the water. The magnesium anode must be replaced in time for the correct and efficient subsequent functioning of the water heater.

If I want to change the anode or clean the heating element, do I need to call a service specialist?

You can really contact our specialists at the service center. They will promptly and professionally “clean” or replace internal parts. You can also do it yourself: to do this, drain the water from the water heater, unscrew the nuts holding the flange, remove the flange, then carefully descale the heating element and replace the anode.

How to carry out EVN prophylaxis: how to flush the tank, do I need to scrape it?

Prevention can be carried out by specialists of the ASC, if carried out independently, then the walls of the tank do not need to be scraped off, scale is an additional protection against corrosion.

At least once a year, the heating element and thermostat are cleaned, the anode is changed once every 2 years, depending on the hardness of the water (consult with an ASC specialist) it may be more often.

Where can I get a magnesium anode?

Magnesium anode can be purchased from the service center.

I want to buy a 100 l water heater for a country house. If the tank leaks during the warranty period, do I have to take it to the workshop myself?

All you have to do is call the service department. Masters will come to your country house for free, repair or replace the water heater. It is forbidden to dismantle the device yourself, because this will make it difficult to determine the cause of the failure.

Can I install the water heater at home myself?

You can carry out the installation yourself by strictly following the instructions. However, when installing the water heater yourself, the manufacturer of the ARISTON trademark is not responsible for damage during installation.

It is very convenient to contact the service centers: the specialists will professionally perform the installation.
