Hi,
I’m Dario.

After extensive and detailed discussion of the GAS WATER HEATER, it’s time to talk about those electrical, especially given the great demands we have had from our readers.

The electric water heater was the most widespread type of domestic water heater years ago, it played the part of the protagonist in the homes of Italians.

Despite the widespread use of gas water heaters the electric ones continue to be used a lot!

This does not surprise me, the motivations in fact we will go to analyze them one by one calmly in this long and exhaustive article.

The guide to electric water heaters

Let’s start by saying that the electrical solution is certainly not the most ecological or economic, but sometimes because of the very limited space we have no alternative for the bathroom at home.

If you are forced to resort to the electric water heater you should therefore at least choose a model that is extremely optimized in terms of consumption, or that allows you to get the best results at the lowest possible cost.

The heating of water for sanitary purposes for our home is not in fact an optional, nowadays hot water for washing and cooking has become normal administration and it is mandatory to find a solution that meets both our needs for comfort and our pockets.

But let’s see what the ideal solution is.

Electric or gas water heater?

First of all, we need to understand if the electrical solution is actually the best one for our needs.

At the moment there is a strong preference for gas water heaters, the reason is simple in fact, as we have well explained previously in the guide always here on ProContro, these models allow to significantly reduce consumption in the short and long term and to save lot.

The electric water heater is certainly cheaper at the time of purchase, unfortunately with the passing of time the consumption of this one will turn out to be clearly superior to those of the gas water heater, the electric current is in fact much more expensive than the gas with the same heating effect of the water.

If you think about the long term it is better to buy a gas water heater, in fact if you take into account the average consumption of a family it is very easy to calculate the savings and realize how it is compared to an electric one.

However, there are cases where it is impossible to install a gas model due to space or legal issues, in fact the Italian legislation on safety on gas systems is very stringent and if you do not want to install an « abusive » device in these cases you will have to opt for an electric model.

There are also situations where hot water is used so rarely, we think for example houses inhabited only a few days a year, or places of work such as offices and shops where it is used very few times and in small quantities.

In these cases you can easily prefer an electric model without too many worries.

The gas water heater

The current trend is all in favor of gas water heaters, and in the coming years it is expected that these will prevail over electric ones.

We must not forget the strong environmental impact that a huge use of electricity can have. If you have global warming and pollution at heart, the choice of gas is obligatory, in fact these are the most ecological models that ensure less impact on Mother Nature.

Buying a gas system, however, can be much more expensive, even the installation is more demanding and usually requires the call of expert professionals.

The electric water heater vice versa lends itself much more to a do-it-yourself assembly and above all it is much cheaper.

Instant or storage water heater?

Another substantial difference to consider is that between instantaneous water heaters and storage water heaters. As suggested by the words that describe them, the difference is in the way water is supplied at the time of the « request » by rotating the sink knob.

Those there instantaneously can supply the water without any limitation instantaneously but they have some problems with the variations of the water flow.

The others instead accumulate hot water inside the tank and when this ends there is a need to « top up », normally it takes a couple of hours for the water to return to its previous level and can be heated.

How to choose the electric water heater

The electric water heaters are very long-lived, they can even work without giving problems up to ten years.

An economic electric water heater will not necessarily be convenient in the long run, because as we have already seen if it is true that gas water heaters allow you to save a lot of money within a year in terms of consumption it is also true that an electric water heater Optimized, it will allow us to keep its costs down on the bill.

Every home and every family will need a specific water heater that meets their needs, so it is impossible to actually establish a unique model that suits everyone.

Very often I am asked: Dario, but tell us practically what do you think is the best electric water heater?

I cannot answer this question because I would find myself in the very difficult position of having to identify a model suitable for all living contexts and all utilities, a mission in which, unfortunately, I cannot risk given the need to consider the model most suited to the situation from time to time examined.

It is also true that there are much more functional boilers, which present a great value for money and many excellent features that allow extreme ease of use and excellent heating performance.

There are different types of electric water heaters, and I believe that at this point of our guide it is essential to deal with them all one by one to be exhaustive and show what are actually advantages and disadvantages of each type and to guide you in this way in an optimal choice without leaving anything to the case.

It is essential to always take into consideration the flow rate of the water heater and the room in which it will be installed, these two elements are the fundamental ones from which to base our eventual choices.

Small electric water heater

The small electric water heaters usually have a declared flow rate between 10 and 30 liters, although reading them here may seem like many not to be confused by appearances, in fact this type of device is only recommended for very small users and contexts in which hot water is required only in sporadic cases, we think for example of offices and shops in which at most we usually need to wash our hands or perform elementary toilet actions. In short, let’s be clear, a few will think of taking a nice shower or a bath while they are in the office.

In other cases they are used in large houses where larger devices need to be integrated, given that it is difficult to bring hot water around in very large houses, or when a house that was originally small was enlarged, in these cases they are very useful because they allow you to generate hot water right next to the toilets that need it.

They are usually cubic in shape.

Vertical electric water heater

Here is the most classic type of water heater, it is cylindrical (although today we find much thinner versions for sale to meet any space requirement) and are installed vertically on the wall.
The capacity is between 50 and 250 liters.

They are built to be decidedly resistant to natural water corrosion, but also to limestone deposits that are very often formed despite all our precautions and the use of special products. Not forgetting the rust that in many cases manages to be a real killer of water heaters.

Very often they are equipped with a thermostat that is used to control the water temperature.

Horizontal electric water heater

Here are some water heaters with a somewhat more unusual shape, especially in our country, many of you I bet you never even saw them live.

These are the electric water heaters, also with capacity similar to the vertical ones oscillating between 50 and 200 liters.

The form that a horizontal installation provides is ideal in rooms where it is not possible to install vertical ones that might go to steal too much living space, therefore the need to refer to such models to solve the problem with tranquility is urgently needed. efficiency.

There are also models specially designed to be used both vertically and horizontally, these are my favorites as they allow some freedom and do not constrain the installation in one way or another by forcing us to choose by force at the time of purchase , with these we will in fact be able to also change ideas during construction and move their location if we wish.

Stable electric water heater

Here are other rather atypical water heaters, that is, those stable there also called a base because they are placed directly on the floor.

This type of very particular form allows us to deal with much more consistent volumes, in fact we start from 50 to get up to thousands of liters.

As you can well imagine devices of this kind are recommended for contexts in which a truly exceptional quantity of water is required and are not highly recommended for normal homes or family uses. They are often used in very large public or industrial environments.

How much does an electric water heater consume?

As we have repeated above, up to the nausea, the electric water heater is a few steps below that gas given its poor energy performance, mind you but it does its duty very well, it is only that with the same results it will take a lot more electric current that will go in some way to burden the bill.

In recent years, however, engineers who are studying how to improve the consumption of these devices have been able to perform real miracles since current models allow performance in certain cases even close to gas models.

Inside a normal home the water heater (equaled perhaps in some cases from the kitchen oven) is the device that usually weighs more on the electricity bill, in some cases you can even arrive in percentage at a cost of 30% on all the bill, think about it.

Having said that it is therefore essential to be aware of the fact that this purchase is vital to the health of one’s domestic finances and that a false move at this stage would risk being discounted in the coming years in a negative way.

Some inexperienced believe they solve it by relying on economic models or even from the Chinese market and in many cases not even equipped with mandatory certificates, thinking illusory of saving.

Friends, I have bad news for you, this kind of attitude is actually counter-productive and risks over time to be harmful not only on your wallet but also on your health and that of your family.

The ideal water heater is the one that combines a low price to the purchase and a saving on consumption, while at the same time it continues to guarantee a great efficiency over time.

Currently there are models that use a convenient heat pump powered directly by electricity, the surface is directly proportional to savings in this case.

Insulation inside the boiler is another fundamental factor to avoid unnecessary and crazy heat dispersions, imagine a little, all these efforts to heat the water completely frustrated by scarce insulation which could cause it to become cold again.

Obviously the most optimized water heaters in terms of consumption are often the slightly more expensive ones, but I can assure you that a few dozen euros invested at the time of purchase could prove to be absolutely the smartest choice in the long term, amply repaid by taking home a excellent safe product and little « glutton » of electricity.

Electric water heaters tend to consume a lot of energy in their minutes and in the first hours of use, then they light up in a much more spaced interval, so that they can always leave the water at the right temperature inside the boiler.

A 1000 W boiler that stays on for 12 hours a day consumes approximately 2 kWh of energy.

In our country, unfortunately, we know that electricity has very high costs, much more than in other European Union countries, this is the main inevitable reason that makes totally electric heating much more expensive than using gas.

In other parts of the world, on the other hand, gas is not so predominant, because electricity costs less and therefore the use of water heaters of this type is not a big problem.

How large should a water heater be?

It is clear that the choice of the size of the water heater to take home must be very careful otherwise you will risk spending more than it should or even buying a device that is difficult to install due to space.

A water heater that is too small compared to your needs risks leaving you very often without hot water, maybe even in the winter months when using cold water for your personal hygiene needs is a real nightmare.

On the other hand, buying an exaggeratedly large water heater will expose you to a significantly higher risk of consumption than you should.

First of all, we must first of all realize how much water we actually need for our health needs, based on a simple calculation starting from the family nucleus that lives in our house.

Two people will tend to consume more or less eighty liters of water every day, four people will be able to consume a good 150 liters instead. As your family grows, consumption will inevitably increase even as you go up, you can easily exceed two hundred liters without even realizing it.

Often we are not very wise in household consumption and we tend to waste a lot of water without realizing it, this is bad because it can aggravate both on our bill and on the environment, so I invite everyone to a more careful use of water, both hot and cold .

After having accurately calculated our consumption it will therefore be necessary to take into account how these are distributed during the day, in fact it is clear and obvious that in some hours of the day consumption will be much more intense while in others lower or even zero.

There are clearly homes where the components will all tend to use hot water in a well-defined time slot, for example before going to work early in the morning.

If you recognize yourself in this case you will have to think about adopting a larger tank, given that the water will run the risk of being consumed before the last person can use them in that specific period of time. Furthermore, it should be borne in mind that using the bathtub instead of the shower involves the use of an enormously greater quantity of water, in this case it will also be necessary to multiply the consumption by 4.

The actual dimensions of the boiler used by our electric water heater will also be very important, in fact the possibility of installing it in the room of our choice will depend on these.

Some are very small and can even be placed under the sink, but these models are recommended only for those with extremely low hot water requirements.

Another solution if you need a lot of water but the space does not allow it, is that of the instant water heater.

The larger an electric water heater is, the greater its consumption. This seems to be obvious but from personal experience it is not something clear to many, so it is important to pay attention to when the actual purchase is made.

There are even some water heaters that work by using decidedly reduced energy consumption, using a heat pump that helps to keep costs very low, saving up to about sixty percent.

A trick used by many is to position the water heater very close to the sanitary fixtures that you intend to use more, for example it is a good idea to keep it very close to the shower and the bathtub, it is clear that it is much more likely that we will need a greater quantity of hot water when we take a bath or shower, rather than when we use a sink. In this way we will avoid heat dispersion.

For the same reason it is good practice not to install the water heater next to very cold surfaces, for example walls that give to the outside, or even worse next to windows, in this way it would risk to make vain all the expensive process of heating the water .

Some opt for the installation of two water heaters in the house, placing a second one inside their kitchen to have hot water when using the sink without having to go and get it from the bathroom.

There is also a very insulating thermal paper to further avoid any type of heat loss and thus reduce costs to the bone.

Moreover it will be good to learn by heart the operation of our thermostat to be able to adjust it harmoniously according to our needs. In fact, it is not mandatory to always keep it at the maximum, risking very large consumption, it can be kept at a more limited temperature that still guarantees a sufficient supply of hot water, in relation to the surrounding temperature.

In winter it will be necessary to keep it higher, while in summer it will be possible to significantly reduce this parameter.

Be very careful because too hot water could also cause you to risk dangerous scalds while showering!

There are very comfortable flow reducers that can be positioned both on the taps of the home sinks and inside the shower, by using them you can reduce not only the use of hot water but also cushion the general consumption of water, going this way to weigh less on the environment.

Best Electric Water Heaters To Save on the Bill

1. Ariston Velis Evo 50 Lt, extremely quiet

Here is the Ariston Velis Evo electric water heater, with a capacity of 50 liters, so not too big but not even small. The dimensions are reduced and therefore allow to avoid the waste of space.

There is also the 80 or 100 liter version.

The boiler is multi-positionable, so you are not bound only to the classic vertical position but if necessary you can switch to the horizontal one.

It is easy to install for those with a minimum of experience with water connections and cannot be easily intimidated by this type of device.

We remind you that while for the gas water heater you need the assistance of a highly qualified technician since you are dealing with gas ducts and there is a need to follow certain regulations that electrical one does not provide for particular regulations or specific attention, what is certain is that if you are a beginner it will always be good to have someone help you, also because however small it is still heavy to place and install yourself.

It is silent and made in a workmanlike manner, the user interface is particularly remarkable and innovative.

It is equipped with a double tank, the boiler is enamelled so it allows not to disperse the heat and therefore to make the most of its power, thus optimizing consumption.

It has a double magnesium anode, a double 5-bolt flange and a safety valve tested at 8 bar, guaranteeing high performance and at the same time good energy savings. The water reaches the maximum temperature of 80 ° C.

It is equipped with an anti-legionella function, perfect if you do not use the device for more than 30 days in a row and in this case the water will be heated to avoid any proliferation of bacteria inside it.

The anti-freeze function serves to prevent the pipes from reaching their freezing point, making them unusable in this way and compromising the entire hydraulic system of the house. In fact it is easy for the water to freeze to break the pipes causing very serious problems that are not very easy to solve in the case.

The self-diagnostic function also allows you to immediately report any user faults via the LED screen located on the front of the water heater.

This function will indicate exactly what kind of problem has just occurred and you will be able to immediately resort to repairs, saving time and money.

Every time the water is heated, the active electrical safety function allows you to directly disconnect the device from the mains supply, thus allowing a level of safety not normally available with other instruments.

Moreover our Ariston Velis Evo will show us very clearly thanks to its spacious monitor-display the moment in which the water is actually hot and ready for use for a nice regenerating shower, in this way it is possible to optimize even more in consumption.

The anti-burn function is not to be underestimated because being very high temperatures if there was not a very careful monitoring of the water that comes out of the boiler and comes into contact with our skin there could be cases of burns even very violent, this type of block instead allows to always keep under control the temperature keeping it in the threshold of 100 degrees centigrade and in this way avoiding the worst.

Dulcis in fundo, the innovative anti-dry function that allows you to avoid overheating inside the system by avoiding the operation of the boiler in the event that there is not actually water to be heated inside it.

2. Ariston Shape Eco Evo, the ecological consumption-killing

A high water heater extremely interesting for those looking for an electric solution. Also on this step of the podium we find Ariston, which as always does not disappoint in this field by presenting us with the Shape Eco Evo model which, as the name suggests very clearly, has its strengths in a yield that is as ecological and smart as possible.

In fact, the ECO EVO product line stands out precisely for the great energy efficiency that reduces consumption. There are several versions of this model, both in terms of capacity and orientation, so you can choose whether to buy the horizontal or vertical version directly depending on the space requirements within your home.

But let’s look at its features now.

It is an interesting cross between a very efficient and attractive design and a set of innovative functions (especially if you opt for the non-basic function) that will satisfy even the most demanding user.

Enameled in titanium with a head at 18 bar it has a very interesting shape, I would dare to say prismatic.

There is also a very comfortable display that provides real-time operating data necessary to take full advantage of the features of this device without leaving anything to chance.

The energy class is the B class, excellent for an electric water heater in this range, thanks to the extra-thick polyurethane insulation.

But let’s try to better understand what this ECO function is all about.

Inside this Ariston water heater we will find a program that will allow us to optimize energy savings through complicated and efficient algorithms that will exploit the so-called self-learning machine-learning that is very fashionable lately in the latest generation devices.

The machine will learn from our daily use and will know how to self-adjust accordingly.

The usual functions already explained within this article are available, such as: anti-legionella, anti-freeze, self-diagnostics, anti-dry, active electrical safety and anti-burn. The same as the HotPoint Velis model.

This is the water heater undoubtedly indicated for all those who have the absolute priority of drastically reducing their consumption, certainly an excellent investment that will prove to be a winner especially with the passing of months and years.

3. Ariston Andris Lux Eco, small for offices and shops

Here is the younger brother of the other Ariston models, this one has as its fundamental characteristic instead the really reduced dimensions and it is recommended for those who for example need to produce hot water inside shops or offices, or places that do not have a continuous need of several liters of water but only occasionally.

The capacity is significantly reduced compared to the other devices presented in this article, but those who have basic needs and do not have a lot of space to mount their own water heater will be happy, in fact in this case we talk about 30, 10 and 15 liters for the three different versions of the LUX ECO.

The design is particular and very interesting, it will not look out of place in modern home or work environments.

The basic technological functions are the same as the models already presented, the particularity in this case is the Flexomix Deflector which allows this small water heater to have a significantly reduced water recovery time so that it can always be available again very quickly .

Let’s think, for example, of an unexpected unexpected shower by one of our guests.

The energy class is A due to its small size, and obviously with consumption so we can sleep peacefully and not fear because this Andris LUX ECO will certainly not weigh down on our bills, at least not to a greater extent than the average of electric water heaters .

The price in this case is a bit high if we consider the clearly limited scope of this small object, but certainly it is not prohibitive if we consider the large savings that it will inevitably allow on the various future bills.

Not everyone is in constant need of large quantities of water, so it is useless to buy a water heater with a boiler of hundreds of liters when you plan to use very little every day, or even to leave it unused for long periods.

As we said before, this is the ideal solution for houses that are used very little during the year or for commercial establishments where the needs of hot water are necessarily limited.

4. Ferroli Calypso 50 Lt, very robust

Ferroli Calypso Vertical Electric Water Heater 50 LT, Class ...

Ferroli Calypso Vertical Electric Water Heater 50 LT, Class …

  • Removable electric resistance in copper. Probe thermostatic control. Magnesium anode to protect the tank. 5-bolt flange to guarantee robustness and ease of periodic maintenance. Temperature level indicator. On / off light. Safety valve set at 8 bar. External manual temperature adjustment. Tank capacity l 48.5 Dimensions LxAxP 440x545x460 mm Electric power W 1200 Voltage V 220/240 Heating time 20 + 55 ° C 2

Here is a good alternative to the Ariston. Ferroli Calypso amazes with its performance at such a low price.

The capacity in this case is 50l, for a modestly sized family, a single who wants to live with plenty of hot water always available or a couple.

Very easy to install and composed of the latest generation materials, at first sight and touch it appears immediately very solid and robust, certainly an excellent choice for those who love reliability and durability over time.

The steel of which it is composed is worked to avoid the action of the corrosive agents that could just accelerate the wear, the cooked vitreous enamelled coating allows it to be very resistant to high temperatures.

It takes about three hours to heat the 50 liters and bring them to 55 degrees Celsius starting from the room temperature, but it is clear that this can vary depending on the season and the latitude to which we find ourselves.

Consumption is class C, so it is certainly not a sample compared to the other models presented, but in general it is a good product and should be considered given that it guarantees excellent insulation and the water remains perfectly warm, what is lost a bit on consumption you gain in this aspect.

5. Ariston 10 Liters, a small counter top with a competitive price

Again Ariston, which still proves to be a great leader in this sector.
We are dealing with a water heater that is even smaller than the one described above, in fact here we are talking about only 10 liters of capacity.

The weight is only 7 kilograms and the installation is actually very simple, designed for service bathrooms where hot water is occasionally needed, it can be positioned both above and below the sink without the need for special technical knowledge.

The price is very low, designed to be used as a secondary water heater, not recommended as a single water heater to keep at home, but great if for example you have a multi-storey house with the need to have hot water available very far from your main water heater.

A great product.

6., Instant Electric

Per chi vuole una seria alternativa ai modelli Ariston senza però cedere a grandi compromessi su affidabilità e prestazioni il Vaillant potrebbe allora essere l’alternativa se si è in cerca di uno scalda-acqua elettrico istantaneo.

Di dimensioni molto contenute può essere installato effettivamente pressappoco ovunque se ne abbia bisogno, i consumi sono ridottissimi e la capacità è davvero limitata, solo 5 litri.

E’ chiaro che questo prodotto è per la nicchia di coloro che hanno bisogno di piccole quantità di acqua da riscaldare in un tempo limitato.

In generale è un ottimo dispositivo nella sua fascia di prezzo.

7. Baxi da 50 litri, un’alternativa economica

Uno scaldabagno che deve sicuramente apparire in questa lista è il Baxi, l’alternativa economica a quelli presentati finora. La capienza anche in questo caso è di ben 50 litri, ovvero quella che basta per soddisfare le esigenze di una famiglia non troppo grande.

Il prezzo non è stracciato ma è di sicuro abbordabile e può essere considerato un interessante investimento che alla lunga farà senza ombra di dubbio risparmiare un bel po’ di euro sulla bolletta.

Il materiale che compone questo Baxi è l’acciaio vetroporcellanato, rivestito da un doppio strato di smalto al titanio e poi ulteriormente isolato con del poliuretano senza CFC e HCFC, in questo modo le dispersioni di calore sono appositamente evitate e l’acqua viene confinata all’interno del boiler evitando che si abbassi di temperatura proprio nei momenti in cui dovesse tornare più utile.

La temperatura viene regolata attraverso una manopola esterna, vi è un termometro in questo caso analogico e non digitale con una spia luminosa che indicherà in qualunque momento se l’acqua all’interno del boiler è troppo calda o troppo fredda.

Un dispositivo chiaramente da considerare per chi vive in un’abitazione di dimensioni non esagerate con un nucleo familiare limitato, se fate parte di una famiglia grande o comunque contate di essere in molti ad usufruire del Baxi è meglio ripiegare su un altro modello più capace.

Come installare uno scaldabagno elettrico

Dobbiamo assicurarci come first step di tenere ben sottomano i tubi di mandata e ritorno dell’acqua che avremo precedentemente acquistato in un negozio specializzato.

E’ chiaro che se stiamo sostituendo un vecchio scaldabagno rimuovendolo dal muro troveremo stesso lì questi due tubi e non ci sarà bisogni di acquistarli separatamente.

E’ forse meglio fare riferimento ad un tecnico specializzato nel caso non si sapesse bene quello che si sta facendo per evitare eventuali danni irreparabili.

Lo scaldabagno va quindi agganciato alla parete per mezzo delle staffe che dovranno essere applicate sul muro per mezzo di un trapano.

Fate ben attenzione al tipo di staffe che sceglierete perché se le prendete troppo deboli o le andate a installare su una parte del muro fragile rischierete di far fracassare al suolo lo scaldabagno elettrico che è di solito molto robusto e pesante.

I raccordi dello scaldabagno vanno connessi al circuito tramite due tubi flessibili e le relative guarnizioni.

Basterà in questo caso seguire le istruzioni presenti su tutti i manuali.

Il collegamento alla corrente di casa va invece effettuato nel seguente modo: bisogna collegare allo scaldabagno i fili della corrente compreso quello di massa, meglio se ad una presa nelle immediate prossimità dell’apparecchio stesso.

A collegamenti avvenuti basterà quindi far partire lo scaldabagno aprendo il rubinetto di mandata dell’acqua assieme a quello dell’acqua calda.

Prima uscirà l’aria e immediatamente dopo l’acqua, in questo momento capiremo che lo scaldabagno si è effettivamente riempito.

Manutenzione dello scaldabagno, come combattere il calcare

Lo scaldabagno deve essere regolarmente controllato per mantenerne inalterate tutte le sue funzionalità nel tempo.

Non è necessario stare di continuo a tenere sotto controllo che tutto vada per il verso giusto dato che i modelli più recenti sono dotati di una tecnologia molto avanzata che gli permette di salvaguardarsi autonomamente nel corso del tempo, ciò nonostante c’è bisogno a volte dell’intervento umano per accertarci che tutto stia effettivamente andando per il verso giusto.

Almeno due anni è consigliato rivolgersi ad un tecnico specializzato per un check up completo, ma ci sono diversi indizi che possiamo ritenere degli importanti campanelli d’allarme che devono spingerci ad intervenire immediatamente per evitare il peggio. Vediamone alcuni:

Un rumore forte nei tubi mentre scorre l’acqua calda ci segnala che la temperatura non è più sotto controllo e sta invece passando molto più calda del previsto.

Se l’acqua non scorre come si deve dobbiamo invece supporre l’esistenza di accumuli di calcare. Il calcare è il più grande nemico dei nostri scaldabagno, e si crea di solito intorno alla resistenza oppure al termostato.

Per rimuovere il calcare sarà necessario aprire lo scaldabagno provvedendo innanzitutto a rimuovere l’attacco della corrente e chiudere l’accesso alla rete idraulica dell’abitazione. Poi sarà necessario far confluire l’acqua in esso rimanente fuori.

Poi toccherà staccare i fili del termostato che dovrà essere sfilato.

A questo punto con una spugna si potrà procedere alla pulizia del dispositivo facendo bene attenzione a non essere troppo bruschi e violenti e magari utilizzando appositi prodotti anticalcare.

In conclusion

La scelta di uno scaldabagno elettrico per la propria casa non è qualcosa che si può sicuramente prendere sottogamba, ne va del proprio benessere psicofisico e anche perché no della propria sicurezza.

Non sono rari i casi in cui infatti per decidere di risparmiare optando su modelli economici o addirittura cinesi ci si trova poi alle prese con grandi problemi di installazione, manutenzione o addirittura si rischia di mettere in pericolo la propria vita.

Il mio consiglio è sempre e comunque di ponderare con estrema attenzione qualunque scelta così delicata per la propria casa e per l’utilizzo del nucleo familiare.

Tutti i dispositivi presentati in questa guida sono sicuramente quanto di meglio può offrire in questo momento il mercato e non c’è da temere perché sono estremamente certificati e testati, ma fate bene attenzione se decidete di ripiegare altrove, specialmente se acquistate da rivenditori non affidabili.

Lo scaldabagno elettrico non rappresenta certo, dal punto di vista economico, la soluzione ideale; c’è però da dire che dal punto di vista dei consumi sono stati fatti molti passi in avanti negli ultimi 20 anni.

E’ vero che in questo momento gli apparecchi elettrici sono molto più conveniente rispetto a prima, ad esempio ci sono delle funzioni interessantissime come l’anticongelamento, ovvero la possibilità per la resistenza di attivarsi nel momento in cui l’acqua si trovi a scendere sotto i 5 gradi per evitare danni all’intero sistema.

Anche l’anti-dry è molto innovativo, dato che non permette al boiler di attivarsi nel caso manchi del tutto l’acqua, per evitare in questo modo il problema opposto, ovvero un eventuale surriscaldamento che può rivelarsi pericolosissimo.

Anche l’antiscottatura è utilissima, che evita che l’intero scaldabagno super i 100 gradi centigradi di temperatura interna, la funzione anti-legionella per evitare l’accumularsi dei batteri, che riscalda l’acqua in automatico nel caso questa si accumuli oltre i trenta giorni.

E’ chiaro che nonostante l’implementazione al giorno d’oggi di queste numerose tecnologie si tratta pur sempre di uno strumento completamente elettrico e quindi se non si presta la giusta attenzione si rischia lo stesso di aumentarne spropositamente i consumi.

Seguendo i consigli di questa mia guida sono sicuro però che riuscirete a cavarvela nel migliore dei modi e a ottenere il giusto riscaldamento sanitario dell’acqua riducendo sensibilmente spese e sprechi.

Secondo i calcoli effettuati dall’Università di Harvard, un nucleo familiare composto da due persone necessita di circa 60-80 litri di acqua al giorno; nuclei familiari più numerosi (dalle 4 alle 6 persone) necessitano, ovviamente, di quantitativi decisamente più alti (190-210 litri).

Questi quantitativi implicano un consumo di energia elettrica non minimale; al momento dell’acquisto di uno scaldabagno elettrico è quindi necessario orientarsi su apparecchi ad altra efficienza energetica che consentono di limitare i consumi (i modelli di nuova generazione arrivano a consumare fino al 65-70% in meno di quanto non facessero i vecchi modelli).

Importantissimo e da non dimenticare quando si procede all’installazione è il luogo che andrà ad ospitare il nostro scaldabagno, è importante infatti che si trovi quanto più vicino possibile agli impianti che andrà a servire con la propria acqua, questo per evitare dispersione di calore durante il tragitto.

Lo scaldabagno inoltre non va mai installato vicino a finestre, non dimenticate questo fondamentale consiglio.

Non si può poi dare una risposta univoca a una domanda che molti pongono quando si parla di scaldabagno elettrici: ovvero se sia necessario lasciare acceso il boiler sempre oppure attivarlo solo nelle ore in cui effettivamente si ha necessità di acqua calda in calda.

E’ chiaro che se la famiglia è di dimensioni ridotte, o se si è single e si trascorre moltissimo tempo fuori caso il buon senso suggerirebbe di lasciare il boiler spento per la maggior parte delle ore del giorno ed eventualmente accenderlo alla sera quando si torna da lavoro.

In questo caso sarebbe saggio considerare l’installazione di un timer per comandare l’attivazione dell’apparecchio qualche ora prima del rientro. In tal caso rimandiamo al nostro articolo sulle prese smart che possono essere impostate secondo il proprio desiderio per attivare i dispositivi di casa agli orari prescelti.
